Respirator question - Resin , fumes, sanding etc

I searched respirator but didn't quite find my answer

Are you mostly using Full Face or just the smaller breathing style while sanding grinding / then resin and fiberglass, gel coat, spray gel or paint??

what type of respirator are you using -- ??

How often to replace the filters?

I do wear eyeglasses - wondering if I should get the full face type ....

thank yu

 

Are you in the industry and plan to use this PPE every day, or are you doing a couple of DIY projects at home?

 

I use Scott Proflow thou any such forced air respirator works with eye glasses I reckon. Replacable filters for any use you need..

 

Just a boat project - heres a link to the project

The basic PPE will work fine, organic respirator cartridges, N95 dust masks, full face mask if you want, gloves, and disposable coveralls.

While the products you'll be working with aren't good for you, the problems tend to be from long term exposure, not short term projects with very limited exposure. And even long term exposure health effects are a bit difficult to identify.

I'm not saying don't use PPE, but there are many other aspects of life that have more of an affect on your health than short term exposure to these products when you are using the typical and easily available PPE.

 

The resin that is common for users to develop a long term allergy to is epoxy and it can be nasty, come on quite suddenly and be permanent if you reach your bodies thresh hold, it takes very little exposure to dust or fumes from it activating after that ,dust from fibreglass itself can give you a rash, cold water and soap is the first response, polyester is probably the least inflammatory but can produce flu like symptoms if you say sleep in the same room as it's going off. Good ventilation helps and the fumes from polyester are heavier than air and tend to sink. One other thing, wash acetone off your hands if you are cleaning with it, it seems to wick chemicals in.

 

I use a 3m 5301 or eq for almost all my work. It is easier to breathe in than an N95 and protects from organic vapors.

 

Saturday was a many hrs miserable grind overhead... boat caught a metal protrusion off a piling on a dock at low tide. It had ground a miserable gash just inside the chine 29 feet. Lots of surface area cutting the bevel. My uniform was a basic head sock, tyvek suit, atlas vinyl glove, dewalt saftey glasses, 3m respirator with dust inserts and a cloth mask under the respirator as my beard is nuts and the seal isn't perfect.

Not fool proof as it still got around to my cheeks, wrists and ankles... but it goes with the territory.

Usually run into fogging issues with the full face masks and good goggles. Often run a shop vac to pull air and clear dust from them. Have a sar but its consumables are expensive and its bulky for some jobs.

My big thing is getting the dust off the skin quickly. I have a camp shower setup that goes in my truck and when we do big projects in the shipyard it gets used a lot. Seems like the treseme conditioner helps a little on the skin itch, although that might be placebo.

When putting down resin, we have 3m masks and organic filters. My favorite gloves are the Costco spider gloves. Although one of my workers likes the nitrile thicksters.

Never found a good way to do glass grinding... it all sucks. Beats rust or aluminum electrolysis so its worth it, but haven't found a good way around any of it. Just get suited up with some good headphones one and get the suffering done.
