If protective pads are used in passenger elevator cars, what must they be?

The requirement for protective pads used in passenger elevator cars to be non-combustible is critical for safety reasons. Non-combustible materials do not ignite and burn easily, which is essential in an elevator setting where fire safety is a paramount concern. These materials help prevent the spread of fire within the elevator car and protect passengers from potential hazards in case of a fire emergency.

In contrast, flammable materials pose a significant risk as they can easily catch fire and contribute to the spread of flames. Painted surfaces might not meet the non-combustibility requirement, as some paints can contain flammable components. While soft and cushy pads offer comfort, they would still need to adhere to fire safety standards by being made from non-combustible materials to be compliant and safe. Hence, non-combustible protective pads are the appropriate choice for ensuring passenger safety in elevator installations.
