Co
Carbon Monoxide
Produced by the incomplete burning of carbon-based fuels, carbon monoxide (CO) is a colourless, odourless, tasteless, poisonous gas often referred to as ‘The Silent Killer’ for these reasons.
Carbon monoxide is present in several different industries, such as oil and gas, food manufacturing and petroleum refining. Carbon monoxide binds to haemoglobin in the blood, reducing oxygen delivery to vital organs, potentially leading to severe health effects or death. Even low concentrations of CO in enclosed spaces can be hazardous, making it essential to monitor.

Due to its odourless, colourless and tasteless properties, carbon monoxide is undetectable to human senses, meaning it may take time for you to realise that you have carbon monoxide poisoning.
Carbon monoxide readily binds to haemoglobin in the blood, preventing oxygen from being delivered to tissues and organs. Low doses of carbon monoxide poisoning can include headache, dizziness, weakness, nausea, vomiting, confusion, and chest pain. High doses can lead to unconsciousness, brain damage, or death. Prolonged exposure at high levels can be fatal.
A risk of explosion is also present when CO builds up in enclosed spaces in concentrations between 12% and 75%.
If you suspect CO exposure, immediately leave the area and get fresh air.
In cases of inhalation, move to an area with fresh air, call emergency services, and administer oxygen if available. If the person is unconscious, perform CPR and seek medical attention.
