Firefighters and other emergency responders often work in adverse environments. The operating environments can be very noisy. Personal Alert Safety Systems (PASS) devices are safety systems that emit an audible alarm signal when an emergency responder
Thermal imaging cameras (TIC) have become a vital fire fighting tool for the first responder community but there are currently no standardized quality control regulations. The purpose of the study was to understand the impact of TIC display image quality
This document reports on the test results of an evaluation of the image quality of thermal imaging cameras used by the fire service. The test methods used were based on the test methods included in Draft NFPA 1801 Standard on Thermal Imagers for the Fire
Eight full scale experiments were conducted to examine the impact of wind on fire spread through a multi-room structure and examine the capabilities of wind control devices (WCD) and externally applied water streams to mitigate the hazard. The principle
Closed-circuit breathing devices recycle exhaled air after scrubbing carbon dioxide and adding make-up oxygen from a tank of pure oxygen. This equipment provides up to four hours of use before oxygen cylinders and CO2-absorbent canisters need to be swapped
A series of experiments was run in a masonry educational building examining the ability of PPV fans to limit smoke spread or to remove smoke from desired areas. Preliminary experiments examined the pressure increase created by portable fans and mounted

The overhaul of a fire scene is a stage of firefighting where respiratory protection is often disregarded due to the perception of low risk and the desire to remove the heavy and cumbersome self-contained breathing apparatus. The need for alternative

This workshop brought together members of the fire service, particulate detector manufacturers, public health professionals, airborne particulate researchers, and standards organizations to discuss the need for better technology to assess the level of
This report documents real-time and time-averaged temperature, global and local equivalence ratios, and oxygen, carbon dioxide, and carbon monoxide concentration measurements made at various positions in an isolated 2/5th scale compartment prior to a
