What is a common cause of fires in lab drawers or lockers?

A common cause of fires in lab drawers or lockers is the improper storage of flammable materials, such as chemicals or solvents, which can ignite due to heat or friction. Additionally, electrical equipment or batteries stored in these spaces may overheat or short-circuit, leading to ignition. Poor ventilation can exacerbate the situation by allowing flammable vapors to accumulate. Regular inspections and proper labeling of materials can help prevent such incidents.
