Can I get some recommendations on respirators/equipment that I should have, before starting this clean up? Thanks!

Iím just going to toss a few things out here for you, Iím sure there are some deep posts on this.

1) how much guano? A coffee cup full or 6-12Ē across entire attic?

2) though people differ on respirators most that do this would agree you are at a minimum
going to be using a 1/2 face quality rubber mask with changeable filters in the P100 level for

(Insulation, dust, and yes reducing risk of histoplasmosis for you and your co workers.

3) blown insulation existing now or fiberglass batts?

4) read this if you never have before :

5) after reading that youíll know not to say you can remove kill or disinfect guano to remove histoplasmosis.
That is still the case all these years laterand I still hear of folks being told their wildlife or pest guys are saying
they can kill histo... youíll see formaldehyde as the only thing thatís ever killed it in a lab.

6) mechanically many ways to remove it in terms of actually physically removing guano. But what way
to do it professionally and give you and your clients the best available removal.

7). How entering the space where the guano is, how leaving with materials. All to reduce airborne dust and
limit liabilities, etc....

8) if people are expecting no odor if they have it currently be careful on what you promise, removing odor can
be a whole level beyond and still have limitations.

7) many folks who lurk or are on here for decades now have been doing this longer than I have so Iím sure youíll get
some good info. Iíve learned before I started from Eric Arnold, people like Ron Scheller and others who contribute on
here and are decades into this type of work.

***on last thing - respirators should step you into get fit tested and knowing you are healthy enough to be wearing
one and that you know how to keep a solid seal on the mask. Things like facial hair and talking a lot can blow the seal
and cause you to inhale insulation bits and all kinds of micro particles.

I say this as a former wildlife disease biologist who was trained in ďhotĒ settings for serious viruses and pathogens
who had to get fit tested before I could start using a respirator of be a first responder.

You only get one chance at your health sometimes, itís worth talking to someone about respirators and getting best for you.

Look also at PAPR respirators, they provide fresh air and are more expensive but are worth evaluating.

There are more things to all this of course more info for what you are facing in terms of home, church, amount of guano, etc..
will get you better answers.

Just my .02.

Thereís also lots of debate about when a client asks do we need the entire attic insulation removed
or just the 2x2í area with the guano on it? Everyone has their own opinion and thatís more debate than
hard and fast rules.

Thank you. This was helpful. To clarify Iím asking this about a home I just purchased. And will need to clean up. Iím not sure yet how deep it is, as itís blown insulation and lofted in areas. But Iíd guess at least a couple inches deep over an 12íx12í area. Thanks for your help, Iíll check into the further resources.
