What is worn by responders during the application of a foam blanket for vapor suppression?

Responders applying a foam blanket for vapor suppression typically wear structural firefighting gear. This choice is appropriate because structural firefighting gear is designed to protect firefighters from heat, flame, and some chemical exposures, making it suitable for operations like vapor suppression in many fire scenarios.

While structural firefighting gear provides adequate protection from common hazards related to vapor suppression, responders must assess the specific incident's risks, including the potential presence of hazardous materials. In situations with identified higher risks, a different level of protection may be warranted, such as one of the other types of protective equipment listed.

Proximity suits are designed for environments with high temperatures, while flash protection focuses on preventing burns from flash fires, and Level A protective equipment offers the highest level of protection and is typically used in more serious incidents involving known or suspected hazardous materials. However, for many standard temperature and chemical exposure situations, structural firefighting gear is considered sufficient, making it the most practical and common choice for responders engaged in vapor suppression with foam blankets.
