ENVIRONMENTAL DATA
NOTES
Carbon monoxide is a product of incomplete combustion of coal, oil, wood. It is present in vehicle exhaust and tobacco smoke.
Depending on the degree of exposure, periodic medical examination is suggested.
No odour warning if toxic concentrations are present.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
