In fire inspections, which item is primarily checked for proper functioning?

Fire extinguishers are critical safety devices designed to combat small fires before they escalate into larger, more dangerous ones. During fire inspections, it is vital to assess whether fire extinguishers are in proper working order. This includes checking for accessibility, appropriate signage, correct type for the potential fire hazards present, and ensuring they are adequately charged and maintained according to established codes and standards.

In contrast, while heating systems, window locks, and ventilation systems are important for overall safety and building integrity, they do not directly serve the immediate purpose of fire suppression like fire extinguishers do. Fire extinguishers are specifically tailored to respond to fire incidents, making their proper functionality a top priority during inspections.
