The dangers of Carbon Dioxide
Carbon Dioxide is a colourless, odourless gas which is a natural component of the air we breathe, yet is toxic in higher concentrations. It is heavier than air.
Increased levels of Carbon Dioxide results in progressive physiological effects (see below) resulting in life threatening situations in high concentrations. It can also deplete the Oxygen content of air, resulting in a risk of asphyxiation. Carbon Dioxide in its dry form is commonly called ‘Dry Ice’.
|EH 40 Workplace Exposure Limit LEL||5,000 PPM|
|EH 40 Workplace Exposure Limit STEL||15,000 PPM|
|300-400 ppm||Normal level in air|
|600-800 ppm||Acceptable air quality|
|1000 ppm||Tolerable air quality|
|5000 – 30000 ppm||Drowsiness, headaches unless exposure is very short|
|3-8%||Increased respiration & heart rate|
|10% – 20%||Nausea, vomiting and unconsciousness – significantly depleted Oxygen levels|
|20% and above||Fast unconsciousness, death|
Safety Gas Detection manufactures Carbon Dioxide detection systems which detect the presence of low levels of Carbon Dioxide, and give a Carbon Dioxide Alarm.
