Which item is a fire safety concern?

• A. Overheating cords
• B. Contact with power lines
• C. RF exposure
• D. UV from sun

Answer: (A)

Overheating electrical cords create a direct fire risk because heat buildup can ignite the insulation or nearby flammable materials. When a cord carries more current than it’s rated for, or if the insulation is damaged, worn, or crushed (and especially if the cord is laid under a rug or attached to devices that generate heat), it can spark or smolder and start a fire. This is a classic fire safety concern in both workplaces and homes.

Contact with power lines is primarily a severe electrical shock and arc-flash hazard, not a typical fire ignition risk. RF exposure deals with energy exposure and tissue effects, not ignition of materials in normal use. UV from the sun is a radiation hazard and skin/eye health risk, and while it can degrade materials over time, it’s not considered a primary fire safety concern in most environments.
