It's the vapor pressure that makes it smell so good!

Wow that sounds unbelievably miserable. I've had to heat gun off old paint from a wooden boat bottom. That is a sucky ass job. I've also had to grease an entire boatyard's worth of jack stands with used motor oil it was my first day working at my family's boatyard. DO you think they were trying to send me a message? No one on here better accuse me of having a silver spoon. I work for my misery!
As to the heat gun on old paint on the wood boat, I've been told and tried using a propane plumbing torch, working it over an area to just bubble the paint was much quicker than the heat gun. However, for obvious reason be careful!

Very true. Keep your respirator or just it's cartridges in an air tight sealed container when not in use, it prolongs cartridge life. And carts are expensive. I keep half masks in a large Folgers can. Fullface carts get pulled and put in a ziplock.

Caused some angst, but an inviolable rule. Vaseline does improve things with beards, but is not reliable enough for serious hazards.

The OP mentioned using "regular" cartridges. This smacks of a particulate filter when he should have been using an organic vapour filter. If so, no wonder it seemed ineffectual!

The wonderful shipwright who built our strip planked boat was youngish and hence invulnerable to that sort of thing. As a result he became so sensitized to epoxies that he can no longer work using serious quantities of such chemicals. Had to build his last yacht with foam and vinylester rather than timber and epoxy... a medium that he hates! A big price to pay for not heeding the warnings (which he was aware of).

So listen up when Minaret (who does this stuff daily) lays down the law!

Cheers,

Jim



Aaww, taking me back to the days of my youth! I wonder if you worked at LL back when I was getting arrested chaining myself to the place with UCB students? The good old days!

I would not recommend this for any sort of seriously nasty stuff, like 2 pak paint, but for stuff where they prescribe "good ventilation" it works very well.

The air compressor for the face mask was quoted at something like AU$1K, but I bought the CPAP machine as a discontinued model from a friend who sells them for a living for just a few $.

Dad recently borrowed the rig when he had to grind out some fibreglass from his old galley and said it was the first time he was able to do such a job while being completely relaxed about his health.

I'm not neurotic about this stuff, but just the ability to relax while working with mildly suspect compounds makes for a better job. OK, you look a little bit like one of those guys from the E.T. movie, but it is so much less stressful. And at the end of the day, you toss off the disposable coveralls, have a quick shower, and you feel human again.

Matt..

P.S. For those that don't know, CPAP machines are devices used by people with sleep apnoea or even mild snoring. There are many manufacturers out there, and they are constantly improving the technology, so people often upgrade them for the latest features. From a strict hygiene perspective their basic function keeps them very clean but if I were buying a used unit I guess I would give it a jolly good clean first.

P.P.S. I have a full beard, so I need the sort of full head cover which uses positive air pressure to keep out the nasties. So does dad, which was why he borrowed mine.



Hoods are comfy, but often too big for work in tight spaces. I don't like to wear one even under a boat. If you are interested in affordable forced air, check out the new Class D rigs. It's basically a high end filter which allows you to plug a fullface in to regular shop air, no special compressor required. Very nice.

Try one of these with the wide burn down roofing tip on it.

Likely so, mate! I was there from '62 until '88, with some time off near the end to go for our first cruise.

Those were interesting times!

Cheers,

Jim

Nah, I wasn't chained to the front gate till '90. I'm just a pup to you! If that was the most misguided thing I'd ever done in pursuit of pretty hippy chicks from UCB, I'd be happy! Talk about dain bramage...

My ex brother inlaw worked at the lab and had throat cancer by his early 30s. I dont recall him being a smoker. I hope the safety standards are better now. _____Grant.

Grant, I'm not sure if you are serious here or not, but really! He worked at the Lab, he got cancer... must have been slack safety standards there. Point proven. Not.
