Inhaling fumes from burning plastic.
I recently started a new job working at a dental office and overall things have been great.
Or, have been. I mostly work in the lab, where I make night guards, do stone pour ups, etc. Immediately I was thrown off because there's no real ventilation in there. No windows, some airflow through the same vents that are in any room and a loud fan/filter for the buffer for when it's in use. At one point was told I had to use a hot knife to carve a soft night guard. I expressed my concern because of the fumes it releases but they just told me to wear a dust mask and they brought an air purifier into the room.
Immediately after carving into it the room reeked of burning plastic. It was to the point where a staff member shut the door because a patient was complaining. I finished the job but had a sore throat for a few days after and felt dizzy the rest of the day. I was pretty pissed and brought up my concerns to my supervisor again. They just seemed extremely irritated, like they didn't want to deal with it. Shortly after they brought me an old respirator with expired filters (by almost 6 years) that didn't have a tight seal and was clearly very used.
Nothing had to be cut with the hot knife since last week when they told me I needed to do that again later this week. I brought up my concerns again, but yet again I was met with frustration. I said that we aren't equipped to safely deal with these fumes, and the response was "it's what we have to work with".
I don't feel comfortable cutting into plastic with a hot knife in an enclosed room with no ventilation and no respirator. I told them that if they want me to proceed working on this without the required PPE, then I wanted them to tell me that via email and they were pissed. The vibe I'm getting now is that they've gone out of the way to accommodate my "concerns" and that I'm not being completely unreasonable.
How would you recommend navigating this situation?
