Last night after cleaning up from working on the Hard Top project, I somehow got uncured resin on my hand. I wear heavy latex gloves while working, and wash hands after removing the gloves with denatured alcohol to be safe. I scratched an itch on my left wrist a few times and rubbed my eye once. This morning I woke up my right eye is swolen closed and both hands have red rash and ichy burning sensation. Oh, did I mention I had to relieve myself last evening???? Uggg.

Got some hydrocortisone cream to stop the ich and burn. Ahhhhh. And some ibuprofen to reduce the swollen eye.

I even took off my shirt in the garage before coming in the house. Maybe the resin was on my pants and I picked it up there. But usually the resin on my cloths hardens and then is not a problem.

So be careful. These chemicals do damage.

Re: Warning for Epoxy users

Over time, exposure to epoxy hardener will sensitize you to it. Skin contact, even vapor will do it.

After that, if you contact epoxy you break out in a psoriasis like reaction. It never goes away... for the rest of your life, epoxy will cause the reaction.

Seriously, wear rubber gloves and a respirator mask each time you mix more than a cup of epoxy, all the time if you can, and work where there's ventilation.

We backyard boat builders may be good at working in unusual spaces that a pro wouldn't even consider, but sometimes that means we're less safe too.

Your boat is not more important than your health.

Re: Warning for Epoxy users

Like EG said, this is one of the issues with epoxy and its part of the reason why epoxy isn't used in production for boat building. Some epoxies are more likely to cause problems than others, but it may be difficult to determine which ones are better.

I hope you have a speedy recovery.

To add to this...any users of epoxy resin should be wearing at least a half face respirator with organic vapor cartridges. A simple dust mask will do nothing to protect you from the fumes.

I used this set up Friday evening when working on my boat and it worked great. I had a fan venting the garage and the respirator fitting snuggly on my face. I didn't smell anything. When my wife came out to the garage she said there was a noticable odor. So, always wear a well fitting respirator with the proper cartridges.

Re: Warning for Epoxy users

Hope you get better soon. I had heard this from a guy who was working at West Marine when I was working on my project. When I did use epoxy I wore goggles, the half face respirator for organic fumes and the really long chemically resistant gloves. When I got to the point of glassing in the new deck, I decided to contract that out to the 'glass shop. I had installed the new deck and as much as I wanted to do the whole thing, the issues of grinding, using epoxy, and the fact that the shop could make it look better than I ever could, made me realize it was worth it to have them do it.
In retrospect, I'd rather do 100 oil changes, brake jobs, or shock replacements, than do a major 'glassing project again. Next boat will be just a few years old at most.

I hear ya on that. I am almost to the point where the major grinding for smooth finish will start. I ordered a few disposable jump suits with hood and elastic wrists/ankles. Not looking forward to it.

Re: Warning for Epoxy users

im bumping this cause its a really important thread.....

we, as back yard boat builders, sometimes think ....it will be ok....i just mixing a little bit........thats when the mistakes happen......poly...or epoxy.....grinding or a simple gellcoat sanding.......we allways gotta wear the right safety stuff........

i saw a pro the other day come into my shop to lend a quick hand.....he carried a box with a handle.....a bit bigger than a breife case.

in it was a full face resporator.....

we all gotta take this stuff really seriously

Re: Warning for Epoxy users

Just an FYI on ordering safety equipment. This stuff is expensive when purchased through home centers, auto supply, etc.

I found Galeton.com had good prices. I ordered a name brand half mask respirator (Surviveair) and filters for dust and vapors, 5 breathable disposable jumpsuits with elastic cuffs and hood, and a box of 50 6 mil thick latex gloves with extra long cuffs with shipping was $84.00

The jumpsuits are only $2.00 each, and the box of 50 gloves was only $10.00.
My parents sent me a check for my birthday the other day, and that covered it. Money well spent.

I decided to buy a brand name respirator that you can get replacement parts for. I called Survivairs office and spoke to someone about what respirator I needed for my boat work with epoxy vapors and grinding glass. They were happy to help, gave me the model and part numbers I needed to order from the Galeton site.

At these prices, there is no reason to buy no-name respirators from places like harbor freight.

Re: Warning for Epoxy users

one more thing to add. most filters for your respirator have a set life span. how many hours before you need to replace. I was told in tech school to always toss the filters in a sealed coffee can or zip lock bag and toss them after 30hrs of use.

Re: Warning for Epoxy users

Conny supply is another saftey outfit that has good stuff at reasonable prices,

I use a full face positive pressure face mask for my stuff when ever possible. Its a bit pricey but worth it.

Quick note on resp. filters, if you can smell or taste the chemical your blocking after knowing you have a good fit, replace them and for gods sake get the pre filters too!

Re: Warning for Epoxy users

Mark42,

Your warning of skin irritation from epoxy contact is valid and in my case quite timely. I've become a little sloppy with its use lately.

However, I believe the concerns over fumes and the need for respirators etc. is misplaced. I specifically chose to use epoxy at greater cost over poly because they (epoxies) DO NOT emit VOC's (volatile organic compounds ??).

I presently have 3 different formulations of epoxy on hand. All of them contain warnings to avoid skin contact and irritation etc. None of them state ventilation requirements which suggests that organic compounds are not given off in the vapors.

On the other hand, I was led to believe that poly does indeed emit VOC's and that carbon filter respirators are absolutely required as is adequate ventilation. (I don't have any onhand to check labels etc.)

I'm not at all suggesting that epoxy use does not present hazards. Acetone used as a cleaner or thinner does emit harmful vapors. But the tone of this thread seems to imply that poly use by a DIY'er is safer than epoxy use and that isn't true.

Re: Warning for Epoxy users

Hi all,

My $.02... (The wife and I build FRP wooden boats for a hobby and have used poly and epoxy...) My guess is that it comes down to an individual's tolerance to certain chemicals...

* We've never had a problem with epoxy. And that includes torn gloves/no gloves, and poor ventilation. Both are terrible ideas, but it happened, and might happen again. (And we buy epoxy in 3 gal kits.)

* Polyester on the other hand make me dizzy and nauseous regardless of ventilation.

One thing is absolutely certain... Sanding cured 'glass (epoxy or poly saturated) without high-grade breathing equipment is crazy. One night the Mrs. and I put in a bunch of hours sanding a glass/ply peapod using only those hardware store 3M paper face filters... When we were done, we were both spitting up blood in the sputum... The next day we drove to Sears and bought the best industrial respirators we could get our hands on.

The point? We all have sensitivities to chemicals and should act safely... But glass dust takes no prisoners. Buy high quality breathing gear, use it and maintain it.

Re: Warning for Epoxy users

When it get's down to what's safe to breath it get's a little tricky. Nothing is safe to breath at high levels, but it can be difficult to tell what is a high level is if you depend on oder. Styrene can be detected by your nose at very low levels, much below what's considered safe in the work place and in most areas of a glass shop respirators aren't required, yet you can easily smell it. A person not use to styrene would think the smell is over powering, but it would still be below the limit.

Other chemicals can have little or no oder but can be much worse for you, so oder isn't a good indication of toxicity.

I think its a very good idea to where protective safety equipment when working with resins and other chemicals and you shouldn't take chances.
But I must say that when I started working with fiberglass around 40 years ago nobody used any type of protective equipment, not even in the worst conditions. At one job it was common for us to be lining the inside of very large steel chemical tanks using a chopper gun, we didn't even use a paper dust mask. Stuff like this was done every day and I have not met anyone that has had health issues as a result of polyester exposure ( I'm sure it must happen though). I do know people that are sensitized to epoxy and the isocyanates in two part paints from far less contact though.

Re: Warning for Epoxy users

Don't mean to bring up an old thread but this was still in my mind...

I'm watching the West System safety/technique DVD and the dude is working with epoxy but doesn't have a respirator on :confused:

Safety glass when sanding or grinding or applying epoxy on overhead surfaces...gee I personally wear safety GOGGLES when working with just dry fabric. I'd imagine that splashing epoxy when mixing or something is very possible and it seems like the DVD would say to wear goggles at all times.

And when "sanding epoxy", to use a dust mask (generic disposal type pictured) or a respirator with organic filters.

This is all straight from the West System DVD :eek:

Re: Warning for Epoxy users

About 15 or so years back I worked for a car dealership which also did body work. I was not in the body shop but worked directly adjacent to it. There was an open 12' overhead door between my work bay and the body shop.
I remember an OSHA rep coming in and sitting the entire shop down for a safety speech. They made an issue of me being so close but unprotected to breathing the fumes. They were forced to put up a plastic door and cross vent to prevent fumes from getting into the mechanics shop area.

Not long afterwards, they had a guy come in to demonstrate a new plastic bumper repair technique. Since I was one that would often do minor body fixes, I sat in on the training. The repair was using a new epoxy to fix or save torn urethane bumper covers. One of the managers asked about breathing the fumes and one the big sales pushes was that there were no harmful fumes and no mask was needed but gloves were supplied with the kits.

Myself, I've used epoxy now for many years, at least as long as it's been around as a fishing rod coating. I've never developed a sensitivity to it but prolonged contact or failure to wash off any hardener that may have come in contact with skin can sometimes produce an itchy rash in that area. Nothing serious but about the same as if I had handled raw fiberglass batting. (That stuff tears me up something terrible, I get a reaction to fiberglass insulation that looks like poison ivy, and I don't have to really handle it).
I have little to no reaction to handling or cutting boat fiberglass, but again, that's done with a respirator, gloves and often either a junk pair of coveralls or a Tyvek suit. I admit I often forgo the Tyvek suit if it's super hot outside. I'll take my chances vs. heat stroke and death in a suit.

I have a box of military surplus respirators I've been using for years. They are designed for silica exposure and chemical exposure. The inserts interchange with the mask that Snap On tools sells as well as a few others. I like the carbon filters since they are twice as deep and easier to breath through. No odor gets through. I've also got a fresh air system that was designed for a local boat builder that went out of business. It supplies outside, filtered, temp controlled air to a mask through a hose. The hose is a bit of a hassle but I find that lowering the air temp can do wonders for comfort on a hot day.
I bought the rig at an auction for probably a fraction of what its worth, but I'm glad I did. I do a lot of welding, and on a cold day, it lets me close the doors, turn up the ventilator fans and still breath clean air while not freezing.
