Wet....30 gallon garbage cans.

 Reducing risk needs a holistic approach, not reliance on one single safety device. 

 

Bingo.

The point is that there IS no answer .... unless you have air sampling done to know what you are being exposed to.  It is not about "OSHA compliance", it is about believing the science that is behind those standards and then it is about your future health.

 

You with a beard and respirator and another person with a beard and respirator could actually have different levels of what gets through to the lungs.  Too many variables.

 

Then there is the level of exposure that the respirator is trying to protect you from.  What you have and what another person has can be different.  Too many variables.

 

Intuitively one would THINK that some of the air going into your lungs gets filtered while some leaks in unfiltered.  But the percentages and the levels are totally a guess.

 

If your go that route.... just pretend that you are mixing without any protection.  That would be the safest mental framework to take.

Check OSHA regulations on respirators, they should have articles on beards.  I have heard Vaseline in the beard to get a good seal, which just sounds icky.  I am female with a very small face, at work we were "fit tested" with half faced respirators in case we needed to use them, I failed since they just won't seal on my face.  So in an extreme hazard environment I wouldn't use them (so no hazardous environments for me :D ) but works fine for painting.  You have to get hazard specific canisters, for example they exist for particulates or organic vapors. 

Good luck with saving the lungs.

 

Used to be the Health and Safety Coordinator for my college.  Nope.. Vaseline is not "legal" if you are in an employment situation.  It is either shaved.... or positive pressure full face respirator.  Fit testing required.  Medical monitoring required.  Right to know education required.

 

SO the real question is how much do you want to gamble? 

 

It is very possible that the concentrations you are exposed to in your studio ops are not even at a level of real concern..... but until you know....... you don't know.

 

Is the gun loaded?  Have you checked?

 

There is no easy answer to this.

In Topic: 3D Printer To Make Master Mould?

29 July 2015 - 08:54 AM

A CNC machine using solid modeling software on a computer (like Rinocerous) can make a master out of plaster or other hard material.  A place I work in Japan does that. 

 

Easier than trying to use 3-D printing extrusion of a material that sets up fast.
