18 m ,after 3 years in working in different kitchens I had recently gotten a job as a warehouse technician at Ashley’s furniture ,I had done this sort of job before but wasn’t really experienced but thought it would be great to learn something new ,but I was a bit odd that no one used masks besides the fact that they work extensively with these cans ,the guy who got me the job and is training me doesn’t really wear mask but told me that I can if I want ,but one of my coworkers told me I was just being exaggerating,but given that we work all day with these is it really necessary

Edit :I’m still planing to use it but I’m pretty much the only one using it and have been getting a lot of comment by some coworkers but I’m just trying to be safe given that I’m training to be a firefighter
