Unusual odors from electrical equipment can be the first sign of a potential fire. If the fire you are fighting begins to spread, leave the area and call for help. Do not use carbon dioxide or ordinary dry chemical extinguishers on Class A fires. Do not use water extinguishers on energized electrical equipment. An Emergency Action Plan should designate one person to evacuate all disabled people in the building.
Fire drills are necessary to test the Emergency Action Plan.
The last person to evacuate a room should lock the door to prevent vandalism or theft of equipment. Elevators may be used to evacuate a building as long as they remain operable. You should occasionally pull the pin and briefly squirt all fire extinguishers to ensure they are properly charged and in good working order. As soon as you evacuate a burning building, go home. No need to hang around.
