What is the OSHA specified maximum distance to an extinguisher for Class D fires?

The correct answer indicates that the OSHA specified maximum distance to an extinguisher for Class D fires is 75 feet. This distance is critical because Class D fires, which involve combustible metals such as magnesium, titanium, and sodium, can burn at extremely high temperatures and require special extinguishing agents.

The establishment of a 75-foot distance is based on the need for quick access to fire suppression tools in emergency situations. Being too far from an extinguisher could increase the risk of injury or exacerbate the fire situation due to delay in response. Therefore, it is essential for facilities that handle combustible metals to ensure that fire extinguishers specific to Class D fires are readily available within this range, allowing for prompt action when needed.

In contrast, other distances do not align with OSHA regulations for Class D fires; for example, 50 feet is generally suitable for other fire classes but does not account for the unique challenges posed by combustible metals.
