Can anyone recommend a suitable P3 for the wearers of glasses.
Face fits have been carried out but both myself and my colleague are struggling with our glasses steaming up after a few minutes of wear.
We have tested the masks on none glasses wearers by having them wear glasses while the face fit is performed. Result = face fit pass but glasses steamed up. The masks could cause more of a hazard than what we are trying to avoid!
Regards

CW,
I'm assuming your using half face masks in my answer.
We used to use half face but ended up replacing them with full face due to issues with fit with other PPE and effectiveness of the seal when doing anything other than being stood upright with minimal movement.
We currently use MSA and Scott full face respirators which have the advantage that special frames with prescription lenses can be worn inside the respirator and the seal cannot be affected.
What product are you protecting against?
Regards,
John

Hi CW
We currently use 3M powered hoods for the people who have beards or wear glasses that cannot wear the 3m half face masks. Feel free to contact me for any details.

You don't indicate what the mask is to protect against.
Keep in mind that if the airborne substance is a sensitiser it may also be a skin sensitiser. In such a situation a half-mask, or even a full face mask, may not provide adequate protection, since these will leave areas of skin exposed with the potential to develop airborne allergic contact dermatitis.
Research shows that this is much more common than many realise.
I such situations only a full hood will be adequate. Of course, this also eliminates the need for fit testing.

Cheers all. The masks are used for type 3 asbestos surveys.

Very surprised at the comment - we have not had any problems with disposables if they have a valve - forget anything without a valve - our analysts wear half masks and our surveyors normally wear disposable - I wear glasses and have had no problems with a 3M 8835
I can not see you using powered for a T3 except for the hairy bits......

Bruce,
we didn't know we had a potential problem until using one with black dust/dirt in a roof space clearing job.
When the users removed their masks their were visible track marks to the nose and edge of the mouth.
All users were experienced in mask use and had gone through the correct donning procedure. They were doing heavy physical jobs which involved a lot of movement.
We have had no indications of any health issues through our health checks but as you can imagine user confidence was reduced.
Full face respirators was our chosen way forward with airlines being the norm.
We use about 300 respirators a week so as you can imagine our training and testing procedures are pretty robust but the cost can be prohibitive,
Regards,
John

Again I am surprised - had you done face fit tests on the disposables - we do have people fail them which presumably means that a percentage people who do not undertake such tests must have fit problems which are not normally seen until you work in a dirty environment such as the one you described.
Even if you have gone to full face and airline you do need to do fit testing.Airlines are fine .... except when you have to move......... but I am sure that the users tell you that.

Bruce

Bruce,
yes all users were face fit tested and do this on a yearly basis. They do all the usual excercises to test the seal but in reality these have little resemblence to the twisting and turning experienced during a job.
I'm aware of the issues associated with the use of airlines having worn them almost daily for my 15+ years as a fitter and I would choose positive pressure over negative every day of the week.
The problems with wearing eye protection and respirators are well known and a reletively simple solution is to issue full face protection and there is enough choice on the market to do this at reasonable cost and effectively.
Regards,
John
