4 Dryer Safety Codes You Should Know

Did you know that the average laundry load entering the dryer will contain about a gallon of water? To remove all of that water and dry the clothes, a heating element pushes hot air into the drum as it spins. Then, that hot air and evaporated water leave through the dryer vent. Because this is a crucial part of any home, damage to dryer vents will often show up on an inspection report from Inspect360. Here are several safety codes that help us ensure every dryer ventilation system is usable and safe.

4 Dryer Duct Safety Codes You Should Know

1. M1502.2 Duct Termination

According to the International Residential Code, duct termination should be outside the home and at least three feet away from doors and windows. For the best safety results and use of your dryer, make sure that you follow all of the manufacturer’s installation guides. Furthermore, duct terminations need to be equipped with a backdraft damper, and you should not install any type of screen.

2. M1502.4 Transition Ducts

The transition ducts are the common flexible hoses that connect the dryer to the outside vent or termination. Code M1502.4 stipulates that these hoses be no longer than eight feet. They also cannot be enclosed within the construction of the house. Furthermore, they should be in one single tube to help prevent lint traps and vent fires.

3. M1502.5 Duct Construction

According to the M1502.5 code, the construction of a dryer duct has to be a minimum of 0.4 mm thick with a smooth interior. This means ribbed vents are no longer being used. Additionally, all duct joints must point in the direction of airflow. Furthermore, sheet metal screws are no longer necessary as these can penetrate the duct and compromise airflow or safety.

4. M1502.6 Duct Length

When it comes to the length of your dryer duct, it should be no more than 35 feet. Every 45-degree angle or bend in the vent accounts for 2.5-feet, while every 90-degree bend equates to 5 feet. If you have a lot of bends or twists and turns in your dryer vent, then you’ll want to get these fixed right away.
