What should you do regarding dryer doors while the power is out and smoke is observed?

In a situation where smoke is present and the power is out, calling firefighters before opening the dryer doors is the safest action to take. This is critical because smoke can indicate the presence of a fire, and opening the doors could potentially introduce oxygen to the flames, causing them to spread and worsening the situation. Firefighters are trained to handle emergencies involving fire and smoke; they can properly assess the situation and ensure that the environment is safe before anyone attempts to approach the dryer.

This approach prioritizes safety not only for yourself but also for any individuals nearby. It allows professionals to manage the scene with the appropriate equipment and knowledge, minimizing the risk of injury or escalation of the fire.
