Extinguishers weighing over 40 lbs should be mounted no more than what height above the floor?

Extinguishers that weigh over 40 lbs are typically required to be mounted at a maximum height of 3.5 feet above the floor. This regulation is in place to ensure that these heavier extinguishers are easily accessible to users in an emergency situation. Since the weight can make handling more difficult, a lower mounting height facilitates easier retrieval and deployment.

In practice, this means that when an extinguisher is needed, individuals can quickly and effectively access it without the risk of injury that could arise from lifting a heavy object from a higher location. Proper mounting height is also crucial for compliance with safety codes and standards, which aim to ensure that fire extinguishers are not only available but also usable by everyone, including those who may have physical limitations.
