Master Streams Contain Philadelphia Mill Fire

The Bromley Mill, a 620 X 500-foot complex that had been pre-fire planned, was the site of what had been long expected—a massive fire. Dating back to 1889, the complex in the Kensington section of Philadelphia had a four-alarm fire that made the sprinkler system virtually useless three months before the larger fire last July 29.

80 Breath Analyzer Kit—A data sheet describing the MiniCO breath analyzer kit for estimating concentrations of carbon monoxide in the blood is available from Mine Safety Appliances Company. The MiniCO estimates carboxyhemoglobin levels by measuring the concentration of CO in breath (alveolar air).

When Roof Should Be Opened Make a Large Hole Immediately

For some reason, reluctance too frequently hobbles the decision to open up a roof when the fire situation demands vertical ventilation. The result is that because of the fear of doing excessive damage, fires that should have been controlled destroy buildings. When excessive heat rises to the roof, mushrooms and starts to bank downward, the immediate effect is that any occupants are in danger of losing their lives and fire fighters will find it difficult or impossible to advance hose lines into the building.

Ladders: Guidelines for Selection, Maintenance and Tests for Reliability

Nozzle, ax, and ladder—from the time of bucket brigades on badges, plaques, and other insignia—these three symbols have stood for the fire service. The ladder is the one major item carried alike by aerial truck and pumper. It tends to be taken for granted. But a closer look reveals some uncertainty about the best answers to such questions as:

Effect of Nozzles on Fires Studied In Terms of Flow Rate, Droplet Size

Despite the almost universal use of plain water dispersed by nozzles during fire fighting operations, there still remains considerable uncertainty regarding how much water it takes to extinguish a fire. Ideally, one would like to estimate the total quantity, application rate, and form of water which would effectively suppress a given fire; and one would also like to identify and understand which factors significantly affect fire suppression effectiveness and fire fighter safety.
