You're doing a PhD in a chemistry adjacent field and you think you're allergic in general to hazardous chemicals?
Even saying you're allergic to hazardous chemical is gibberish. Hazards are classified in many ways. Some chemicals would be safe to eat, but like to explode. Others are highly carcinogenic but would not cause any immediate ill effects. Some cause bad burns at high concentration, but at low concentrations are totally harmless.
Are you saying that if you walk into an active chemistry lab, in general, it causes you difficulty breathing, hives, etc?
