DANGER
•
Carbon monoxide (CO) is a colourless and odourless gas and therefore not
perceivable.
•
At the end of a gas calibration the bottle with calibration gas must always be
closed.
•
At the first sign of symptoms indicating carbon monoxide poisoning start first
aid treatment.
Symptoms and First Aid with Carbon Monoxide Poisoning
•
Headaches, dizziness, ear buzzing and near collapse (after several hours or
towards the end of the working day) are symptoms of CO positioning.
•
Smoking increases the CO-concentration in blood and can lead to poisoning
symptoms even when there is a low CO content in the air.
•
Acute life threatening condition if fainting or unconsciousness occurs!
