What type of cabs require the use of safety bars or safety gates along with appropriate PPE for firefighters?

The scenario described involves unclosed cabs, which typically refer to vehicles or equipment that do not have enclosed spaces for the occupants. In these situations, safety bars or safety gates are critical because they prevent firefighters from accidentally falling out during operations or when the vehicle is in motion. This risk is heightened in open environments where access to hazards is more pronounced.

Additionally, the use of personal protective equipment (PPE) is essential in this context. Firefighters face various dangers, including exposure to smoke, heat, and potential debris. PPE ensures that they are protected against these hazards while performing their duties, especially in vulnerable positions typical in unclosed cabs.

In contrast, closed cabs offer more protection to occupants from external elements, reducing the need for additional safety features like gates or bars. Open and reinforced cabs may also have specific requirements, but the unclosed cab clearly emphasizes the necessity for enhanced safety measures due to the higher risk of exposure.
