To prevent dryer fires, regularly clean the lint trap and exhaust vent, keep the area around the dryer clear of flammable items, and avoid overloading the dryer. Never use the dryer without a lint filter and ensure the outdoor vent flap opens properly during operation. 

Elaboration:

• Lint Trap and Exhaust Vent:

  Lint is a major fire hazard because it's highly flammable. Clean the lint trap after every load and inspect the exhaust vent for blockages, ensuring it's clear of debris. 

• Clear Area:

  Keep the area around the dryer free from flammable items like cleaning supplies, boxes, or clothing, which could easily catch fire. 

• Overloading:

  Avoid overloading the dryer, as it can cause overheating and increase the risk of fire. 

• Lint Filter:

  Never use the dryer without a lint filter, as it can collect lint and become a fire hazard. 

• Ventilation:

  Ensure the outdoor vent flap opens easily when the dryer is operating to allow proper airflow. 

• Professional Cleaning:

  Consider having a professional clean the dryer duct regularly to remove accumulated lint and reduce fire hazards.
