Dust masks revisited.

[CHJ]

Looking good Chas

Hmmm, I've had someone else mention that I looked better with it on. :lol:

Thanks for your time Mark, which helped considerably in the 'justification' stakes.
Still getting the odd comment from you know who to the effect that she will need to take two books with her next time I drop in for a few minutes.

Hope I didn't take too much productive time out of your day, at least we put some of the world to rights.

I take it that you are happy with it then Chas.
Anything that you don't like about it :?:
Is it noisy inside compared to the Trends :?:
Does it fit nicely on the head :?:

Is the colour optional or fixed, can you add a scented air freshner, has it got inbuilt head phones. :lol:

Be fair it does look a bit space age Chas though I have heard Mark Hrecommending them before.

Quite happy Paul, nothing to date.

Is it noisy inside compared to the Trends :?:

Much quieter, can't hear the air movement with expelair extractor running.

Does it fit nicely on the head :?:

Yes, a bit of trial and error with selecting top and brow band adjustment for 'best fit' but as it's so light, fine adjustment needs a couple of hours of use to establish any fine tuning needs on brow band tightness.

Got to do something to bring my image up to date Pete.

No it isn't Tom, not something to invest in lightly.

But with my allergy problems and the knowledge that the current Workplace Exposure Limit for Wood Dust is only 5mg/m3 it starts to justify itself. I spend a long time exposed some days.

Wish I had some means of measuring the dust concentration to help folks check shop conditions, but my interpretation is that if you can see dust settling or covering your extractor filters after a days activities you are most likely above that sort of level.

 

[lurker]

Chas you are about right there.

I used to "do" dust workplace exposure testing and to be quite honest no fancy kit beat simply cleaning a horizontal surface at about nose level and than looking the next day for dust.

I used to have a 1ft square sheet of shiny Stainless steel cleaned with meths that I left for a working day and then go back and draw a line with my finger.

Don't as someone suggested use the air from a compressor - its full of oil & will pipper up your lungs faster than wood dust.

Hi

This is what I use as I had it from when I was doing some two pack paint spraying all you need is a compressor to hook it up to, it is light and the carbon filter cleans the air have a look at the links.

The only draw back is that you are attached to the air line but I do not find it a problem


Need to have the compressor out of the workshop


Hope this is of help to someone.

Roger

No don't do this!!!!
The oil mist is bluddy dangerous

 

[Jenx]

DEFINATELY NOT !!

Breathing Quality Air is a science all of its own.

Chas knows I'm sure.. but for the benefit of anyone who doesn't.. Heed Lurkers shout, cause it's reaaly reaaly dangerous to breathe standard compressor air.

I do 'breathing air' apparatus sometimes.. and its all got to be specially degreased and god knows all what... Never, ever breathe standard compressor air.

 

[CHJ]

Your in Print Folks, well cyberprint anyway, See the UK Workshop forum link.

 

[lurker]

If others want to follow Chas' lead, here are some slightly cheaper options

I agree with what you are saying but I use a carbon coalescing filter in the regulator which I was told was sufficient am I wrong if so I will stop using the mask.

Carbon takes out oil mist. You need a column of molecular sieve, about 3 times the C volumn, to reduce the CO, CO2, and water levels to acceptable. Renewable time on filters depends on volume of filter, volume of gas passing through and time (unless your filter system is really, really sealed at both ends and at every joint inbetween). Filters can be anywhere post compressor and pre mask, so your belt weight need not be affected,
