gas, but, being colorless, odorless, tasteless, and initially non-irritating, it is very diffi-
cult for people to detect.

ppm - Parts Per Million - is used to describe concentrations of contaminants in air.
in the event of alarM caused by a critical CO concentration level, keep calm and
carry out the following actions in the priority order:
• Open all windows and doors to increase the rate of ventilation.
• Turn off the appliances and stop using them where possible.
• Evacuate the building leaving the windows and doors open. You may re-enter the
property only when the alarm has stopped.
• Get immediate medical assistance for anyone suffering the effects of carbon mon-
oxide poisoning (nausea, headache), and report that carbon monoxide inhalation is
suspected. Contact the gas or other fuel supplier on their emergency phone number
in order to identify and eliminate the source of carbon monoxide emissions.
