Fire safety is exceptionally important in a laboratory, as they tend to have significant numbers of highly flammable chemicals, which could lead to the fire being very severe very quickly. If fire drill procedures are not obeyed, it leads to a high risk to safety for all persons in the laboratory. The rules pertaining to a fire drill in a lab vary from laboratory to laboratory, so you would need to check the fire safety procedures for the lab where you are working.
