Putting a box of matches in the washing machine and dryer is highly dangerous and should never be attempted. Matches are designed to ignite when struck against a rough surface, and the friction and heat generated during the washing and drying cycles could cause the matches to catch fire.
Here's why it's dangerous:
Friction: The motion of the washing machine's agitator or the tumbling action of the dryer can create friction between the matches and other items in the machine. This friction could lead to accidental ignition.
Heat: Both the washing machine and dryer generate heat during their operation. If matches are present, this heat could be enough to ignite them.
Airflow: Dryers have a strong airflow to help dry clothes. If a match ignites inside the dryer, the increased oxygen supply from the airflow could cause the fire to spread rapidly.
To ensure safety and prevent accidents, always check your pockets and laundry for any potentially hazardous items, such as matches, lighters, or other flammable materials, before placing clothes in the washing machine or dryer. It's crucial to keep such items away from heat sources and follow the manufacturer's guidelines for safe operation. If you suspect that matches or any other flammable item has accidentally ended up in the laundry, remove them immediately before starting the washing or drying cycle.
