What are the shoulder and waist straps of the SCBA made from?

The shoulder and waist straps of the SCBA are made from Kevlar and Nomex with PBI fiber because these materials were specifically chosen for their superior heat and flame resistance, which is crucial in high-risk environments such as firefighting. Kevlar is known for its high tensile strength and durability, while Nomex offers excellent thermal protection and is effectively used in garments that require high levels of safety. PBI fiber enhances this combination, providing additional thermal stability and resistance to combustion. Together, these materials ensure that the SCBA remains safe and functional in extreme conditions, thereby protecting the user from exposure to hazardous environments. This combination of materials significantly improves performance and reliability, which is essential for the safety of firefighters when they are operating in potentially dangerous situations.
