What is the maximum height allowed for panic bars on exit doors?

The correct answer regarding the maximum height allowed for panic bars on exit doors is based on safety regulations set forth in building codes, specifically those associated with accessibility and emergency egress. Panic bars must be installed in a location that ensures they can be easily reached and operated by individuals, including those who may have disabilities.

The standard maximum height for panic bars is typically set at 1.12 meters (or 44 inches) from the finished floor to the top of the bar. This height ensures that the mechanism is accessible for most users in emergency situations, allowing for swift exit through doors without complicated maneuvers. Having the panic bar positioned at this specific height balances the need for accessibility with the structural requirements of the door itself.

The other options present heights that fall outside this standard, making them less compliant with current safety regulations. Hence, the value of 1.12 meters aligns accurately with standardized building codes designed to facilitate quick and safe egress in emergencies.
