When is a driver required to have an approved gas mask on hand?

A driver is required to have an approved gas mask on hand when transporting specific hazardous materials, particularly those that pose a serious inhalation hazard, such as toxic or corrosive substances. This requirement is determined by the inherent risks associated with the materials being transported.

For vehicles carrying inhalation hazard cargo, including gases like chlorine and other toxic materials, the risk of exposure to harmful vapors or gases in the event of a leak or rupture is significant. An approved gas mask is essential safety equipment that enables the driver to protect themselves from toxic exposures, making it a crucial safety measure for these high-risk transport scenarios.

Therefore, having an approved gas mask is mandated not just for vehicles carrying chlorine, which is a well-known inhalation hazard, but also for any vehicle moving toxic materials and specifically any cargo classified under the inhalation hazard criteria. This comprehensive approach to safety underscores the importance of being prepared for potential emergencies in transporting hazardous materials.
