Electrical equipment suitable for use in an air-handling space must have which property?

Electrical equipment suitable for use in an air-handling space must have low smoke and heat release properties. This requirement is critical because, in the event of a fire, the materials used in equipment installed in air-handling spaces can contribute to smoke development and heat release. High levels of smoke can obstruct visibility and create a dangerous environment, while excess heat can exacerbate the spread of fire and damage nearby components.

Choosing equipment that has low smoke and heat release properties helps ensure that, should a fire occur, the risk to occupants and first responders is minimized. This is particularly important in air-handling spaces, where air circulation can rapidly spread smoke and harmful gases throughout a building. Thus, regulations mandate that equipment intended for installation in these spaces must prioritize characteristics that enhance safety and reduce the risks associated with potential fire incidents.
