Before cleaning a dryer vent, what safety action should you perform?

• A. Disconnect power to the dryer and ensure it is completely cool; for gas dryers, shut off the gas supply if applicable.
• B. Leave the power on and clean with the dryer running.
• C. Remove the vent cover and start the dryer.
• D. Pour water into the vent to flush lint.

Answer: (A)

The key safety action is to disconnect power to the dryer and make sure it is completely cool; for gas dryers, shut off the gas supply if applicable. This stops the dryer from starting while you’re cleaning, prevents moving parts from unexpectedly turning, and protects you from burns on hot surfaces. Shutting off the gas removes the risk of a gas leak or ignition if a spark occurs during cleaning. Lint in the vent is highly flammable, so working on a powered, hot appliance creates a real fire hazard. Once power is off and the unit is cool, you can safely access and clean the vent. Leaving power on, cleaning with the dryer running, removing the vent cover and starting the dryer, or flushing the vent with water all introduce unnecessary risks of shock, burns, fire, or equipment damage.
