The other day I got involved in a job where there was a lot of dirt, which in turn created clouds of dust... We're talking the kind of stuff drifts halfway down the block, thick, billowing clouds of dirt particles floating everywhere, the air in the entire backyard was covered in dust, stuff was everywhere you could hardly see. Figuring a bit of dirt never hurt anybody, and having been in this business now in my 5th year, I did what I usually do which is to breathe at strategic times and turn your face away etc, etc... I honestly do not believe a pollen / dust mask would've made a difference, it might've helped but it's not enough regardless... We're not talking your standard daily pollen intake which is normal in this business, I'm talking at least 10 times more. Once I got done I knew I had done something to myself I might pay for later, I felt ok but something was off, I could just feel it. 3-4 hours later I had a fever, runny nose and a bad cough... Much like the flu but now on my 3rd day, even cold medicine only helps a little. Everything hurts, it's like the worst case of spring fever, literally like a bad case of the flu. Come to find out I am lucky because dust can actually kill you, I am putting this here so other people can learn that dust and pollen in great amounts is highly dangerous and before I attempt another high dust content job, I will wear a Gasmask capable of withstanding Chemical Biological warfare (I ain't joking cauz if you felt the way I've been feeling for the last 3 days, heed the advice because those stupid dust and pollen masks don't get a good seal and if they do you can't breathe - get a gasmask I am not joking). Oh by the way, a decent gasmask is 100 dollars and one filter is 30-40 dollars so if you don't wear one, at least include the cost in the price in case you get sick, you might need the money. I got my $60 / hour but I should've charged more, considering. Ahhh well, live and learn.
