If an appliance is installed in a storage garage, how high above the floor must components capable of igniting flammable vapors be located?

12 inches
18 inches
24 inches
30 inches

The correct answer is: 18 inches

When an appliance is installed in a storage garage, any components that have the capability to ignite flammable vapors need to be positioned above a specific height from the floor to ensure safety. The correct height is 18 inches. This requirement is in place to minimize the risk of igniting vapors that may accumulate close to the floor, as many flammable vapors are heavier than air and can settle at lower levels. By placing these components at 18 inches above the floor, it creates a safer environment by reducing the likelihood of ignition sources coming into direct contact with flammable vapors that may be present. This height has been established based on safety standards and practices aimed at preventing fires and ensuring the overall safety of installations in environments where flammable materials might be stored or used.
