In situations involving hazardous material fires, it's crucial to prioritize safety and avoid escalating the situation. Waiting for qualified firefighters is the most prudent choice because they are trained to handle such emergencies and know the specific materials involved, including the correct extinguishing agents to use.

Using water or any extinguisher without the right knowledge could actually worsen the fire or cause dangerous reactions with the hazardous materials. Waiting for a supervisor may be too slow and could put lives at risk since they might not have the necessary training or knowledge about the specific fire. Similarly, using the first extinguisher you find carries the risk of employing an inappropriate method, which could also exacerbate the situation. Therefore, the safest course of action is to wait for professionals who have the expertise needed to manage hazardous materials.
