when burnt, release toxic fumes

Question 12

composite materials

Answer 12

contain fiberglass, etc that when broken, they release tiny materials that are easiy enhaled and bring on asbestosis - type symptoms

heart attack

cancer (larynx, mouth, throat, pancreas)

lung disease

emphysema (shortness of breath)

Question 16

How does nicotine work

Answer 16

it’s a stimulant at low doses (helps concentrate, improves memory and arousal)..

and it’s a relaxant at high dosage (sedative)

nitcotine isn’t a carcinogenic but can hinder hte body’s ability to get rid of mutant cells

Question 17

effect of tobacco

Answer 17

contains: carbon monoxide & cyanide -

reduce elasticity of alveoli and clogs its surface, so oxygen doesn’t diffuse properly into the blood

increase illness due to reduce immunity

bind to the blood cells and reduce oxygen binding - hypoxia

narroiwn of blood vessels/increase vescosity of the blood - increase stroke risk

**less tollerance to g- force
**

affect cell division in the heart, altering the heart shape

Question 18

caffeine

Answer 18

**physcoactive stimulant that acts on the central nervous system - increases alertness, wakefulness, improves muscle coordination

it’s also a vasodilator - relaxes blood vessels whicn can increase uptake of medicine.

Question 23

doses of alcohol

Answer 23

it can degrade performance at 0.04%

can be fatal at 0.4%

however, pilots should not drink 24 hours prior to flying.

Question 24

effects

Answer 24

in mild doses:
relaxtion, euphoria, sense of well being

in moderate doses:
reduce inhibition, over confidence, impulusive, imparied judgement

in slightly high doses:

Question 25

alchohol and drugs

* burning interior * toxic fumes from dangerous goods in luggage/passenger cabing * smouldering fires from electric systems short ciruits, burning cigarettes, etc) * Air conditioning system (anti-cice fluid sprayed into fresh air inlets, lubricating/hydraulic fluid leeking into it because of damaged pumps, system failure releasing hot, unmixed bleed air into AC ducts) **what doesn't cause it - ** overheating breaks can cause fire but happens outside the cabins so no exposure to fumes Engine and APU fires are detected before components melt
