The hazard you cannot smell: carbon monoxide
Where combustion equipment is used matters.
In immediate danger or with serious injury, contact local emergency services. This article is not live emergency assistance.
Carbon monoxide is colourless and odourless and can cause severe poisoning. Keep outdoor stoves, charcoal and fuel generators out of homes, vehicles, tents and garages.
Distinguish battery equipment from combustion
Identify whether backup equipment uses batteries, electricity or fuel, and read its permitted conditions. Cold weather or an open window does not make outdoor combustion equipment suitable indoors.
Place generators appropriately outdoors
CDC advises fuel generators outdoors, more than 20 feet (about 6 metres) from doors, windows and vents, never inside a home or garage even with openings. Follow equipment and local requirements and use suitable CO alarms.
Leave and seek help if poisoning is suspected
Headache, dizziness, weakness, nausea or confusion can have different causes and should not be self-diagnosed by AI. If CO exposure is suspected, get to fresh air and contact local emergency services rather than re-entering to investigate equipment.
