According to NFPA 1970, what feature is required on structural firefighting protective coats and trousers?

The requirement for retroreflective trim on structural firefighting protective coats and trousers, as specified by NFPA 1970, serves a critical purpose in enhancing the visibility of firefighters in low-light conditions. This trim reflects light, making firefighters more noticeable to their colleagues and to others in environments where visibility may be compromised, such as during nighttime operations or in smoke-filled areas. The presence of retroreflective trim is essential for safety, helping to reduce the risk of accidents and ensuring that firefighters can be seen clearly while performing their life-saving duties.

While water-resistant materials, flame-retardant coatings, and built-in communication devices are indeed important features for the safety and functionality of firefighting gear, the specific emphasis on retroreflective trim addresses the crucial need for visibility in hazardous conditions, making it a unique and vital safety requirement recognized by NFPA standards.
