Even with high velocity water, it can still become polluted, even if the levels are indeed lower. In using water as a main source of fire fighting, it is clear that there will always be some level of toxicity in the water that is utilized in the process of stopping these fires. Ultimately, the best method of lessening fire-water is lessening fires.
Examples include PFOA and PFOS, frequently present in water-resistant textiles and sprays conferring water-resistant properties to textiles and fire-fighting foam. [3] Data from animal studies of PFOA indicate that it can cause several types of tumors and neonatal death and may have toxic effects on the immune, liver, and endocrine systems.
He invented fire-fighting foam, which was successfully tested in experiments in 1902 and 1903. [1] In 1904 Loran patented his invention, and developed the first foam extinguisher the same year. [8] The original foam was a mixture of two powders and water produced in a foam generator.
Toxicity can also vary with the organism's placement within its food web. Bioaccumulation occurs when an organism stores toxicants in fatty tissues, which may eventually establish a trophic cascade and the biomagnification of specific toxicants. Biodegradation releases carbon dioxide and water as by-products into the environment. This process ...
The department's three water tanks, which hold about a million gallons each, ran out Wednesday morning, Janisse Quiñones, chief engineer for the Los Angeles Fire Department of Water and Power ...
It does not produce the characteristic white cloud like CO 2 and is difficult to direct when fighting large fires. Halon 1301 is ideal for armored vehicles and spacecraft, because it produces fewer toxic by-products than does Halon 1211, which is critical for combat or space conditions where a compartment may not be able to be ventilated ...
