my name is arya chambers and i'll be your moderator for today's webinar just two notices before we begin first if you're joining webinar via mobile device please note that you'll have the option of viewing either a panelist or the presentation and you can change your view by simply swiping left or right on your screen and second we encourage you to ask questions throughout the webinar via the questions chat section at the end of the presentation i'll read out your questions for panelists to answer with us today we have aj patel and chris mahoney aj is our business development manager and has over a decade of experience in the oil and gas industry including time as a reliability engineer and maintenance and planning execution lead chris is an application specialist who joined our team in 2018 and provides solutions that repair protect and improve all facilities with applications like secondary containment coatings concrete repairs cooling tower repairs and more for today's webinar we're going to touch on these three main subjects what is considered a secondary containment where the governing bodies that regulate containment area standards and then lastly we'll go through some examples of secondary containment maintenance issues as well as big solutions with that i'm going to pass it over to aj to get us started all right thank you very much for that uh wonderful introduction as always arya so good afternoon everyone welcome on this uh beautiful thursday at least that's what it is here in new jersey a beautiful thursday morning as arya mentioned our conversation today is going to be framed around secondary spilt containment um and you know secondary spill containment comes in lots of different shapes and sizes there's various methods for it but we're going to have a few areas of concentration today so specifically we're going to talk in terms of metal dikes so when we think about secondary containment we think about metal dikes we're looking for situations right where my my laser pointer is you may have multiple tanks or maybe even a single tank we know what the volume is inside we want to build a tank dike out of metal to essentially hold and contain the material uh in the event that that that vessel might be substantially larger you'll actually see these um containment dikes actually come in as concrete and so you know we'll have a little conversation around some of the challenges that can happen there as well uh another application in in fact this is this isn't like it like except for just the last order so we're all carving and this is when you want to keep you have two large areas and you know that you have a chemical or some kind of uh material that you don't want to spill into it over to another area you generally understand the volume of what's being held in area one versus area b and or area two and you basically want to prevent it from getting over the proverbial hub so curving is another type of secondary containment and then finally um when we think about loading and offloading areas so a lot of times we transport uh chemicals and other materials by rail by truck you know and so those those vehicles and those transportation methods we also have to think about secondary spill containment there why do we have to do that because if you're in the process of loading and unloading something happens to the disconnect it falls off it pops out and you know we've seen that before and now all of a sudden you have whatever was supposed to be inside of the um was was supposed to be easily moved from you know the tank vessel itself to another tank vessel has come out so you often times you'll see a setup like this and we have an example one but you know there you'll see little holes like you'll see here and essentially those are drains so you'll see them pour out from the primary containment of the drains and really they serve a common purpose and that's the stop a spill from leaving its primary containment area and causing harm to people or the environment so why do we do it because look it's the right thing to do but the government tells us to do it as well so two two kind of uh factions control this uh the first one the first agency is the environmental protection agency and as their name goes they are concerned in protecting the environment so anything that's going to impact the environment in a negative way they want to make sure that when it spills that there is a secondary containment to make sure you're keeping it in place they focus on this material entering the waterways and the legislation itself the rule itself is the spill prevention and control counter measure rule osha essentially does the same thing they have the same concerns but in their case they have a focus on the material that can pose a risk to human health so they are worried about the human health the the human impact the epa is worried about the environmental impact ultimately they work hand in hand and we should be worried about both so anything that's an oil or anything that's a harmful chemical and it's contained in some kind of primary containment will require a secondary spill containment plan and that basically says hey if this thing lets out are we going to handle it and so the reason we have these rules is because we you know as as industry has gone over over the years we've learned many many lessons in terms of watching something spill out and ultimately impacting our water so this is a map from 1969 to the present of some of the larger oil spills that have affected u.s waters so it's not largest oil spills in the water it's oil spills that have affected water so one example is the ashland petroleum spill in 1988 out in florida pennsylvania which is by pittsburgh and it led to the contamination of the monaco halo river and in this example it was a 3.8 million uh gallon diesel tank which ultimately collapsed now the reason why it collapsed yeah that's that's absolutely a conversation but not a focus here but they had 3.8 million gallon tank and they only had enough you know secondary containment to contain 2.5 million gallons so as you can imagine some of that overflowed and this was on land and ultimately the oil itself or the diesel itself ended up inside of the river and moved on to the ohio river so environmentally a six inch thick oil slick moved to the ohio river that's that's roughly the thickness of your iphones right so that's about six inches thick that's a lot of oil from a societal impact 23 000 residents were without tap water why because as this material hit the land it's going to work its way into our into the water table which is you know where we actually get those aquifers are where we get our drinking water and so once that's contaminated we lose our our places from which we get water and then economically 18 million dollars in fines and cleanup costs and i can promise you this almost 30 years later it's going to be a whole lot more so just taking a look uh you know pictures say a lot this is where the tank used to be you can see it completely collapsed it's obliterated all of these other containments were filled up uh it was almost like a lake next to the tank itself it's an extremely dangerous situation one spark in the wrong spot and this thing would light up so you already have a much larger hazard than even you might think right on face value and then when you look at the impact of the river you know i've personally spent time on emergency response i've seen oil spilling to spill into rivers before i've been a part of containing them and quite frankly when you're talking about six inches thick there there's very little that you're going to be able to do in a quick emergency response to help you clean that up and that's just going to create bigger problems and so when we talk about solutions for chemical containment areas we're not just talking about you know the obvious thing which is okay i have a volume of x that i need to contain have i done my math correctly we absolutely want to be a part of making sure that you've done that part right but also beyond that we want to talk about what can happen even if you're volumetrically correct so anytime you have a containment area if you follow my laser pointer here you're always going to have some kind of a corner some kind of a rim that you need to make sure has good integrity so these corner areas when you're made of metal oftentimes that's where you'll find a weld a weld is an area of a lot of stress uh when containment is put together and quite frankly an area of stress is a potential opportunity for failure so we want to take a look at those if you're talking about a concrete containment you know you might be in a position where you kind of got slap sitting on each other and you might have caulk that may go bad uh delamination is another potential area where you may be exposed the lamination is essentially when concrete is put down and it's installed incorrectly what happens is it becomes white and flaky it starts falling apart it doesn't really have great integrity and all of a sudden you've got a lot more porosity in your concrete and it's just going to be that much quicker that if something does spill into your secondary containment now it's going to work its way into the soil cracking is pretty self-evident you have very large slabs of concrete the ground starts moving the cracks appear you know whatever you're trying to contain moves right into the crack i think you you folks can figure that one out and then finally uh you know in the event that you've got some expansion joints put into place you really want to watch those expansion joints because again much like you would see in the corner areas that's where you're going to see a lot of caulk sometimes that caulk isn't necessarily chemical resistant and even if it is if it starts breaking apart because it dries out over time the fact of the matter is it's just another opportunity for your chemical to enter the soil and so our conversation today is really going to be about what are the different ways that we can offer you some support in you know one figuring out is your containment good enough two you know what are the things that we can do to help you repair that so i'm going to go ahead and kick it over to chris mahoney he's our application specialist that's going to talk a little bit more in depth of some of the examples um i talked a little bit on the high level get really involved with the examples and then we're going to have mark uh who's our technical manager join us for a question and answer so chris take it away thanks aj good morning everyone uh so we're going to take a look at some actual work that we've done here at banks industrial group on secondary containment um here we have a before answer shot this is actually at a local chemical plant um there's secondary containment here for the rail car loading area so the way this works is the raw car pulls into the station here for loading there's a retractable arm over here on the left that comes over top and fills the tanker in this case with sulfuric acid and the containment here below is you know to capture any potential spills that may occur during the filling station process so if you look closely each panel has a drain in it and these drains would capture any spill and funnel into the underground storage unit now the underground tank was actually in good condition the reason they called us out was because of the issues they were having on the surface so the left photo is a close-up of an area where they were having some of this bombing issues along their seams over time the elements just baking in the sun and the movement of these heavy rail cars uh create these issues so we had to address those um a lot as a along with giving it a top coat so what we did was we power wash the entire station with grit to give it a good profile we then addressed these issues here with a product called belzona super wrap which is a carbon and fiberglass cloth mixed with 100 solids resin this gave it the structural integrity it needed but also you know bridge the gaps that you see here so once that was set up and cured we then applied two top coats of belzona 4311 over the entire loading area which has a excellent resistance to sulfuric acid so overall this job took us less than two days and the customer was you know very pleased with the final results this job was in a wash down room at a food processing plant where they use various types of acids during their wash down process so over time these chemicals you know put their toll on the concrete as you see here some of the really bad areas you know it just softens the concrete and chews it up so basically what we have to do is we come in we power wash the entire area remove any of the deteriorated concrete and um you know vacuum up that's what these guys are doing here and once that's cleaned up we can then backfill those bad areas with our belzona motor grade mix for structural repairs this these this actual product has almost two and a half times the strength of concrete so these will be a long-term solution for this customer once those areas cured we then applied a two coat system over the entire room so not only did we do the floors but as you'll see we also did about two feet up the walls the stairs leading into the room and then what you can see in the picture we did the drains and the pits also in the corners so now obviously they have a much better system in place and it also allows a lot a much easier cleanup process for their workers so anything that's left on the floor from their wash down can now be just squeezed into the appropriate drains this next one was pretty nasty it was uh it was a leaking acid tank so the leak occurred in the pipes area here right above the containment so it was just a slow drip but over time as you see here on the left it just took its toll on the concrete and it really really busted it up and ate away at it so we came in during one of the shutdowns um and we were able to get all this done in less than 24 hours so we basically showed up um you know 7am on i think it was a thursday we work around the clock and we're done around three or four a.m the following day so not only was the customer please that we were able to provide a solution but they were really happy with our ability to respond quickly and you know the scope of work here basically was when we showed up we neutralized the acid with baking soda and then power washed the area removing any compromised concrete and we back filled in the bad areas with a product called belzona 4181 again another strong chemical resistant product once those areas were rebuilt we then put a two coat system over the entire containment as which is the red finish that you see here we did besides the fluids we also do the curve along the top as well as the wall here in between the two areas and um you know so now this is this is structurally sound and ready to go for any potential spills this video on the right here is just an illustration of untreated concrete and how it reacts to an acid spill so as you see it just absorbs the acid and um you know it's soaking into the concrete the red the right side is actually a belzona treated portion of concrete and as you see when the acid is poured on top of that belzona coating it just kind of pulls and stays at the top of the surface so if that were to happen here in our containment area it would basically just stay on the surface until they were able to clean up the actual spill this next job was a hospital sump that they had installed basically they decided to recover heat from the waste water in the laundry room by installing a heat exchanger the system required a sump for the wastewater to pass through and since it was drilled from solid concrete they had to find a way to you know coat this and protect it so what we did was if you look here on the left you'll see these drill core marks we filled those in with belzona 4141 and then screeded over a two coat system over the entire area so not a very large job in size but from an environmental standpoint still very important this next one was definitely larger in size fortunately for the customer they didn't need to coat the entire contained area this was at a wastewater treatment acility and their cost of containment here you'll see the white tanks they're filled with um hydrochloric acid and those the containment here was actually in good shape but what we had to do was provide a solution for them along their columns and walls they were having separation and crapping so and as well as between the floor and the walls so these these black lines that you see here uh throughout um are actually our belzona products so it's 2211 is the name of it it's an elantra product so what that does is it has elasticity to allow movement with the concrete that it actually has but also providing chemical resistance so if there were to be a spill this product could help absorb and and contain that that chemical we thought this would be a good slide to incorporate into our presentation because it just illustrates how you know not every containment is going to be the same and every repair or application is not going to be the same either this was kind of a unique application as well so this was a chemical storage facility they reached out to us because they were looking for a way to prevent any spills that may occur inside their warehouse from leaving the building so what we proposed and what we came up with was a farm system that we installed in front of their doorways you know the the concerns were they have forklifts driving around their warehouse with pallets of drums filled with chemicals and it worked if one of those drums were to be punctured or to spill again they just needed to prevent that material from leaving the building so these berms were built by us in place our prep basically just involved grinding up the concrete to give it a good profile so our belzona could anchor into it we use the former um to give it this nice curved look that you see here and once that was set up and cured we then just put a top coat of a high viz yellow on since it is a high foot traffic area and we wanted to be conscious of you know the safety of the workers the final job we'll look at here is a truck loading pad at a chemical manufacturer so this was an outdated fiberglass mat system i believe it was installed in the late 80s they needed you know a new solution for this system for this area so we came in and we first had to address the fiberglass matted and remove that obviously since it was deteriorating which was no easy task it was actually on the job site for the for one of these days as the guys were removing that and we had multiple you know scrapers um shovels pry bars anything we could use to get that up and out so that was that took some time and then once we did you'll see here in the left hand corner there's some deep uh concrete repair area that needed to be addressed as well we use our mortar grade to fill those in we diamond grind cut at the entire surface area for a good profile and then uh we applied our belzona 4000 series two coats and what we did was we actually incorporated some garnet on the top coat for a slip resistant surface so that way the truck drivers and anyone else that might be walking in this area you know are safe from basically slipping that also helps dissipate the heat from the tires of these large uh trucks so in the summertime you know when it's about 95 degrees out and these trucks are pulling in here you know approximately 10 000 pounds of weight the tires are already on fire from driving on the hot asphalt so we want to help dissipate that heat and protect the system that we just installed overall this job took about five days we worked 10 hour shifts during the day and then followed that with 10 hour shifts at night so the five days that it took to complete kept us in within the allotted time that the customer allowed for us to do these repairs and um you know they were extremely happy with that because these truck delivery deliveries are essential to their plan operations so again you know they were really pleased with the final product but also our ability to stay on schedule so i hope these were you know helpful in showing ways that we can help your facility basically some takeaways that we want to leave you with are you know you want to properly identify the areas of your second secondary containment and put a plan in place to you know protect these areas um frequently conduct inspections to make sure that they're still in compliance and check for any identified degradations and then if you do repairs obviously we you know you can reach out to us and we will be happy to help you with those um those areas but now i'm gonna kick it back to arya and she's gonna field any questions that you may have for aj or myself arya all right thank you so much thank you aj and chris for a great presentation um for the audience to know we are bringing mark borsky on he is our technical manager and he'll be here to answer questions along with aj and chris during this q a session just so you know you will receive a follow-up email after this webinar is over it'll include some more information on secondary containment solutions as well as a link to the recording of this webinar that will be placed on on youtube later this afternoon if you want more information on think big solutions be sure to visit our website at banksindustrial.com and visit our big learning center which has everything from interactive solutions maps to past webinars informational videos and case studies also if you're interested in learning more about belzona you can visit our website at belzonareptech.com this will stay up for the remaining of the q a session please be sure to send over your questions and we're going to go ahead and get started with aj if you could um thank you for sharing secondary containment solutions do you also service the tanks within the containment areas so that's a really good question so yes obviously if you have secondary containment and you might have a spill that means whatever your primary containment is uh obviously failed or failed in some way so yeah and generally speaking as a belzona uh dealer and as with the zona products we are able to actually go in and depending upon the service and the and the temperature of the containment and the way in which it felt it failed there may be opportunities for us to not only help you repair that particular piece of equipment but also we can help you evaluate other pieces of equipment which could potentially uh be exposed and may potentially have the same problems we can help you with preventative solutions there and if you have new containment areas that are new primary containment areas that are going into service and you're concerned about potentially those causing problems we can work through solutions that can help you prevent a loss of primary containment under those conditions as well great thank you so much aj another question we have i'm going to send this over to mark our facility uses steam tracing and we experience coating failure in our containments under our steam traps how would you address this issue that's actually a really good question so um coatings that you would use in a chemical resistant containment area are going to have different heat resistances based on the coating typically when a coating is specified for containment area the information gathered is usually that it's going to be operating at ambient temperature so it's very common for the coating that's chosen for that containment to not be able to handle the heat from from a steam trap um so that being said that's a localized issue so um you know while we well coding and protecting secondary payments is is very very important um it's also um the infrastructure of the plant so um you do want to manage the costs related to that so as you move into these higher you're going temperature resistant into more expensive coatings so what we'll typically do is mix and match coatings within within a vessel or within a containment um to maximize you know what we can do from a quest standpoint but also putting the proper coding in the proper place so um in containment a large containment area that may have a scene drops in a couple of places we might coat the entire containment with our standard coating which can take temperatures generally up to about boiling and then we can either install a patch of a high temperature coating directly under the steam trap but what we've also done is is bonded a piece of stainless steel or coated coated steel under the steam trap basically to take that take the brunt of that heat since that's only going to be a localized area that's a really good question we see that all the time where the containment coating has been penetrated at the steam trap and once you have that penetration you've basically lost you've lost containment at that point great thank you so much mark um for bahoney could you let the audience know what areas we service for both companies yeah absolutely um so as a distributor of belzona products we do have a geographical area that we um you know sell in which is new jersey delaware western new york and eastern pennsylvania um for us to do these repairs we can actually mobilize you know anywhere in the country basically so we don't have any restrictions uh as to where we can do these types of repairs no we do have throats on here from australia i don't know if we're gonna go that far to uh yeah but i think everyone else within it was within within reach i wouldn't mind the trip i'll go great thank you before i ask this next question next question um francisco i see that your hand is raised if you would please submit your question via the questions section and i'll be happy to relay it to the panelists for them to answer mark another question what are the chemical resistance requirements for coatings and linings and secondary containments it's another really good question so um the requirements here in the us basically are the expectation is that a chemical spill is going to be cleaned up immediately as quickly as possible um generally within 72 hours so once again this this goes over to cost when you look at the chemical resistance of a particular coating um you're generally looking at whether that coating is suitable for full immersion in that chemical 24 hours a day three to five days a year or ten years let's say um in a secondary containment you may not need that level of of chemical resistance so using that chemical resistance chart might drive a client to need to choose a coding that is is more than what they actually need for secondary entertainment so one of the things that we've started doing here at belzona is creating a chemical resistance chart that that has columns for full immersion for your first services primary containment service and then we also do specific testing for 72 hours and uh for for 60 days so we can then recommend the appropriate coding for secondary containment without having uh to stretch the budget let's say into something that uh you may not actually need for that secondary containment that being said if you do have a spill and you have a coating in that containment that is only rated for a short-term duration you mean as part of the cleanup and it's part of the remediation you may have to recode that containment but you know you're you're hoping that your primary containment is gonna is gonna is is gonna stay so hopefully you're not using your secondary containment great thank you mark for aj could you give a brief overview of our companies so that the audience understands our two companies yeah no problem so uh banks industrial group and belzona repair technologies are kind of two two companies that kind of exist together so the repair technology portion we're basically the consultants and distributors of the belzona technology itself think of banks industrial group as more the contractor arm that will actually come out and install and execute the work for you awesome thank you i hope that answered your question if it didn't please refer to the question section i'll make sure to clarify it um poor mark could you speak on the different types of containment codings that there are and we have this question here that asks what's the max temperature and ph resistance of this product but i know that there are a variety of products that you could use for different solutions so could you just give a brief overview sure um so ph is a common is a common thing that we're i'll jump to that and i'll back up a little bit uh when we when we want to specify a coding for chemical resistance whether it's in it a secondary containment whether it's a primary containment whether it's in a processed vessel we want to know the specific chemistries that are in there the ph the ph is important but the ph doesn't tell me what chemical is in there we may have a low ph uh with with an organic acid that that coating may not be resistant to or we may have a really low ph with another um inorganic acid that the coating is very resistant to so it's very important for us to know the specific chemistry and chemicals that that the coating may or may not see there's a variety of coatings primarily you're looking for probably an epoxy coating within a containment um as you get into uh the more acidic environment you're dealing with sulfuric acid or hydrochloric acid you're going to move to a coating that has some nova component of it um it's really it's it's gonna vary a little bit on that it's the same uh information that we gather for for any coding that we're gonna saw we need to know the temperatures we need to know the chemistry um and then we also look at other things like you know what do you do to clean the area we may put a chemical resistant coating in containment and then it's steam cleaned or there's some sort of cleaner that's used in there that is aggressive um the question was also about temperature in a containment really the highest temperature you're really gonna ever deal with is really whatever the boiling point is of that material because you're you're open to the atmosphere um you may get something a little hotter just as it comes out of the tank for example uh asphalt might be a good example you know asphalt runs above 300 degrees so you know when it comes out of the tank it could be that 3 350 temperature but as it sees the air it's going to cool down so our coatings um temperature resistance uh is for for instance like that is is going to be around 400 degrees which is well above anything that you would see um in a secondary containment i would expect we see molten sulphur sometimes that can be pretty hot and then we have test data for specific things like that that we would address but um we need the information we put it into our database and come up with an answer for you great thank you so much mark um if anybody else has any questions feel free to send them through right now i'll give you a few seconds and if there's anything else that the panelists feel like they missed or that they wanted to touch on this is a great time to do so there's one thing i want to address one more thing we're talking about chemical resistance um and the novel acts so when you get into your acid resistant coatings you're going to get into coatings that are more highly cross-linked so they're they tend to be more brittle and one thing you see in concrete containments is concrete um in its nature tends to crack it tends to shrink it tends to move with heat um so you have to be careful what coatings you put in a containment area that they're not too rigid so for example you know we have developed a coating that is is a little it's acid resistant but it has a little bit more flexibility to it that can handle those micro fracture and entertainment because if you have cracks in your containment and and they transmit it through the coating we call it mirror cracking when the concrete cracks and cracks the coating um you then lost containment so you need to need to make sure that you're you're using a coating that's going to be flexible enough to move with that concrete and handle those micro cracks in the concrete awesome we did have one more question come through i'm gonna leave this up in the air sorry about that do you have bonding agents to bond your repair mortars to the existing concrete yeah so that that's actually a really good question and maybe that even gets a little bit into the conversation around you know the surface prep and how do we how do we actually adhere belzona to concrete itself so um the good thing about belzona and the good thing about concrete with concrete being so porous is that it provides belzona material the ability to anchor directly to the concrete itself and so the bond between the belzona and the concrete is actually stronger than the than the the strength of the concrete has with itself so if it's gonna if it's gonna break apart you'll actually see the bond between the concrete and the belzona remain and that'll be where it's stronger cohesive strength of concrete is less so with that said when we're gonna when we're gonna go in and we're looking to repair a concrete you know area and you might see some of those areas might have been eaten away you know aside from just general cleanup it provides us very good anchor points and what we would do is we'd go in with belzona mortar and we'd kind of build out that concrete and kind of make everything flat level and then from a cost perspective that might be less and then we would go over it with a chemical resistant um material then and that'll help you rebuild your concrete so it looks better so it's flat it's nice it looks appropriate but then we'd be able to offer you the chemical resistance as well yeah i just want to jump in real quick because the bonding agent that's that's more terminology that would probably use with a cementitious repair concrete there's bonding agents that you put on to to try and to get the concrete to stick to the existing concrete which which it really doesn't really well um chris chris mahoney had an example there you guys saw the uh the sump that had the red coating in there that was so our repair boards are epoxy so there's no water in them there's there's epoxy resin and then you've got your aggregate mixed in and so by nature they're already extremely chemical resistance and many times the repair mortar can be the coating so in that example uh that red material was a high temperature acid resistant repair mortar and there was a primer that went on there just to just to help it adhere to the concrete but that was a one step application there was the primer was applied and then the the belzona 4181 repair motor was installed and that was it that would be an example of something that would replace acid bricks for example so um there's no need for a coating on top of that it's non-porous and chemical resistant also might i add the next belzona the next webinar we're going to do is on concrete and concrete repair so we're definitely going to get more in depth on that next time thank you um just one more follow-up question mark you mentioned the resin um do you have an estimated cure time for that resin so that's a question we get all the time with all of our materials is how long does it take to cure so when we mix epoxy together we're creating a chemical reaction and it's it's all dependent upon temperature the hotter it is the more quickly it's going to cure the general rule of thumb is about every 20 degrees that you move the needle upwards you and this is fahrenheit every 20 degrees fahrenheit that you increase the temperature you have the cure time so and there's a couple different cures there's cures to the point where you can walk on something for example and there's there's full core where it gets its full chemical resistance so typically most of our materials are cured the same day where you can you can walk on them you can drive on them for more chemical resistance it me it may take you know several days before it reaches its full chemical resistance cure for secondary entertainment that's not as critical as it would be for a process vessel where we would be looking to reach that full cure prior to putting that vessel back in in service um so generally the answer is the next day you can you can utilize that containment as far as getting in there walking around um servicing the owls and tanks and whatnot thank you all so much for presenting and for being here for this q a session thank you to the audience for attending at this time we're going to wrap the webinar you will receive a follow-up email with the contact information for all panelists as well as a recording of this webinar so that you can re-watch or you can reach out to us if you have any more questions thank you for being here and have a great day take care everybody you
