TRAINING Firefighter Topics Self-Contained Breathing Apparatus (SCBA) Conditions Requiring Respiratory Protection Smoke

Video length: 2 min 53 sec video about a wood smoke that happened in Aviston Illinois. The particles of wood smoke are extremely small and therefore are not filtered out by the nose or the upper respiratory system. Instead, these small particles end up deep in the lungs where they remain for months, causing structural damage and chemical changes. Wood smoke's carcinogenic chemicals adhere to these tiny particles, which enter deep into the lungs.

Video length: 28 min 15 sec video about poisons in the air pumped into plane cabins and cockpits may be linked to brain damage. Scientists say that chemicals in contaminated air are connected to health problems being experienced by pilots. Cabin crew cabin crew have long blamed exposure to jet engine fumes for memory loss, tremors, lethargy and other symptoms of so-called aerotoxic syndrome. Peter Julu, a consultant neurophysiologist at the Breakspear clinic in Hertfordshire, said his tests on pilots with memory loss leave no doubt that they were poisoned by fumes in the air used to pressurize Verb 1. Half the air we breathe on-board is recycled but the rest is drawn from deep within the engines and cooled before being pumped into the plane.
