full face respirator and wearing eye glasses

hello

can you wear glasses with a full face respirator? If not is there a certain spectacle kit someone recommends ? I have a opti-fit full face respirator if that helps?
 
There shouldn't be a problem wearing glasses under the mask except they have a tendency to steam up. They make some anti-fog cloths to clean your glasses or you can clean them with soft soap and wipe them dry instead of rinsing them. The trace of soap helps prevent them from fogging.
 
ok but where the arms go back to my ears it breaks the seal on the mask. I'm getting fumes coming in at that point, not a lot but enough to bother. I have a low pressure air fed respirator that puts out 5 cfm to my mask, I'm not sure why it still comes in because of the positive pressure in the mask?
any help would be greatly appreciated

You evidently don't have enough cfm. Did your mask come with a little tester to check for this?
 
I wear reading glasses for close up work like painting. I cut the bows off a pair and tied on strings. Elastic would also work. If you have an old pair of prescription glasses this would work. This works well for me using a full face supplied air respirator.
 
Yes you reduce the quality of the seal with the glasses however like others have said if you have sufficient volume of air the air should be going out there instead of in. The problem is with the pump rather than how the mask fits your face.
 
I've got a 3/4 hp pump with 10 cfm max, and have 50' of intake hose for clean breathable air at all times with 100' of out let. I'm wondering if the outlet hose is too long? also on a day that it 60 degrees F, the air to the mask gets really hot. is that from the long outlet hose?
thanks

My guess is that the inlet hose is the problem. I use 100' of outlet on mine with no hot air even on 90 F days.

I think you are overworking the pump and the inlet is not letting you get air through. Why do you have an inlet in the first place? I just set my pump outside.
 
(quoted from post at 13:43:54 04/30/19) where is the pump?, you might just be recirculating your fumes

I think it is in its original packaging on a shelf for the time being.
 
the intake is at the opposite end of building outside, its coming in thru my mask you can see it on the face seal
 
yakob, is your 100' hose full through? I got 2 50' hose sections hooked together with a quick coupler between them, someone told me one time that 2 50' sections together will cause restriction?

I honestly can't recall, but I do think mine is one piece. It is corrugated hose as well which would be more restrictive than something smooth theoretically. Is yours corrugated?

Rather...what system do you have? I have the "BreatheCool" one from Turbine Products.

The quick coupler on mine seems to have a pretty good hole in it but you might swap that out for some garden hose connections like on the ends or some other kind of splice and see if it helps. I would not think that the coupler would explain the temperature of the air being high, though.

Try some things while you aren't painting: Get rid of the intake hose and see if the temp corrects itself.
 
(quoted from post at 15:02:44 04/30/19) Pardon my ignorance here, but, why do you need a exhaust hose, mine does not have one just a one way valve.

Intake and output on the pump.
 

Opti-fit has a spectacle kit shown on line #962260, which may fit your mask. It should be available from where you got your respirator, they might have to order it. Your optometrist may be able to get a universal kit. Or as noted you can make something from an old pair of glasses.

You are correct in the bows/temples break the seal of the mask, which is a no-no. I have had to wear supplied air for work around industrial chemicals and gases. The seal must be maintained even with a positive pressure air supply. I had to have a spectacle kit to use full face respirators (supplied and filtered) and for Scott air pack respirator use.
 
I have a SAS low pressure air pump, and yes Jim I agree even with positive pressure you need a good seal to your face otherwise the chemical comes in.
I tried the spec kit specific for this mask and it was too big and didn't fit the mask or on my face, so need a new plan.
was looking at spec kits that 3m offers I don't know if they would work in this mask?
problem is with all this experimenting it cost's a lot everytime I try something
 
according to my flow meter with the 2 50' hoses connected together I only get 6 cfm to the mask, and with just 1 50' hose I get almost 8 cfm to the mask, going try that and see if it helps
