Protective Shelter Antiback Draft Valve

Protective Shelter Antiback Draft Valve is a type of equipment that falls under the supply class of Safety and Rescue Equipment. It is specifically designed to be used in protective shelters to prevent backdrafts during firefighting operations.

Backdrafts occur when a fire consumes all available oxygen in an enclosed space, causing a sudden influx of fresh air when a door or window is opened. This influx of air can lead to a rapid and explosive re-ignition of the fire, posing a significant risk to firefighters and occupants.

The Protective Shelter Antiback Draft Valve is installed in the ventilation system of a protective shelter to control the flow of air and prevent backdrafts. It is designed to automatically close when it detects a sudden increase in air pressure, effectively sealing off the shelter from the outside environment.

This valve plays a crucial role in ensuring the safety of firefighters and occupants inside the shelter during firefighting operations. It helps to maintain a controlled and safe environment by preventing the occurrence of backdrafts.

The Protective Shelter Antiback Draft Valve is categorized under the supply group of Safety Equipment and Environmental Protection Equipment and Materials, specifically in the subcategory of Rescue Firefighting. This indicates that it is a specialized equipment designed for use in firefighting and rescue operations, with a focus on protecting both personnel and the environment.

Overall, the Protective Shelter Antiback Draft Valve is an essential component of safety and rescue equipment, providing an added layer of protection during firefighting operations in enclosed spaces.
