Scott,
The most official way to go just to be certain is to always follow OSHA and CDC guidelines for the type of approved
respirator or PPE.
That disclaimer being said, most folks are using particulate style that hold disposable cartridges in the P100 type.
If you are trying to keep attic insulation particles and airborne particles from guano, bird droppings, raccoon and other
this style is inline. Usually attached to either a half or full face rubber fitted mask with adjustable straps, though you
can go to a higher level if you like with a PAPR (this unit though pricey blows clean air into the covered hood and mask
area so that it keeps the bad out and you breathe air filtered through a cartridge system worn on the outfit. Some folks
don't like them, but they are the top end for protection.
Some folks would also protect their eyes depending on the type of materials you are removing, so consider the full face
option if you want to not have to wear separate eye protection.
Another disclaimer that is rarely discussed is the need to have fit testing done and to know that you are physically fit
and able to wear the unit. As an ex fed we were required to have this done annually to be allowed to wear the unit.
I'm sure you've worn a mask before and know as most due that your breathing can be more labored and this can put
more stress on you while working in tough conditions. Folks don't often think about the potential negatives that can
come from being in a respirator too long in a hot or just stress inducing work site.
Heat is a killer on its own, but heat, plus respirator and tyvek and gloves and you now are heading there quicker, so just
so I said it, consider those things too when planning your projects and work. I try to avoid hot attics just as any of the guys
on here do, but we all end up in them at some point so be careful, stay hydrated and understand the strain the respirator
and other ppe put on your body.
Hope that helps, I like northern safety for my filters and other gear and like the MSA rubber masks compared to others I've
tried.
Many on here have lots of experience with this topic but I noticed no one had posted yet so thought maybe I could help until
someone else chimes in.
Good luck,
Justin
