Toxic Hazards Flashcards
What is carbon monoxide?
Carbon monoxide is a product of combustion of organic matter under conditions of restricted oxygen supply, which prevent complete oxidation of carbon dioxide (C02)
Carbon monoxide characteristics?
Carbon monoxide is colourless, odorless, tasteless, and non-irritating making it difficult to detect. It is poisonous
Haemoglobin has a ‘____’ higher affinity for carbon monoxide than oxygen
Haemoglobin has a 200x higher affinity for carbon monoxide than oxygen.
Are the effects of carbon monoxide accumulative?
Yes
Carbon monoxide chemical symbol?
CO
What are some sources of CO?
Cigarette smoke
Exhaust gases
Does our susceptibility to CO poisoning increases with altitude because of the lower levels of pp02 available in air.
True
A person smoking 20 cigarettes a day will have a carboxyhaemoglobin concentration in the blood of about ‘__’%. This gives an effect of a non-smoker at a cabin altitude of ‘___‘ft to ‘___‘ft
A person smoking 20 cigarettes a day will have a carboxyhaemoglobin concentration in the blood of about 7%. This gives an effect of a non-smoker at a cabin altitude of 4000ft to 5000ft
Do piston engines produce more CO than turbines because of the incomplete burning of fuel in the cylinders
True
Symptoms of CO poisoning.
- Feeling too warm
- Cherry red complexion
- Dimming or blurred of vision
- Severe headaches
- Feeling of sluggishness
- Tightness across the forehead
- Pressure in temples
- Slower breathing rate, or breathlessness
Pilots actions if CO contamination are?
- Shut off heating
- Open fresh air vents
- Land if symptoms do not diminish
Other toxic hazards?
Any fluid related to aviation is toxic.
