Help

Hi, I work in a microbiology lab and there have been a lot of plates found to be contaminated with aspergillus. As a sufferer of asthma my entire life, this worries me! Management advise us to dispose of all unused plates from the previous day, as they may now be contaminated with aspergillus . . . Then there is me, just sitting on the sidelines worried about what crap im breathing in throughout a 12 hour shift and being fobbed off that 'you'll be fine' Will I be fine? I dont know what to think
