HOW CAN DIFFERENT LEVELS OF CARBON DIOXIDE AFFECT ME?

  • 0.04% (400ppm) – this is the normal level of carbon dioxide in the atmosphere
  • 1 – 1.5% (10,000 – 15,000ppm) – slight effect on chemical metabolism after exposure of several hours
  • 3% – (30,000ppm) – carbon dioxide is weakly narcotic at this level, resulting in deeper breathing, reduced hearing, headaches and an increase in blood pressure and pulse rate
  • 4-5% (40,000ppm – 50,000ppm) – breathing becomes deeper and more rapid. Signs of intoxication becomes more evident after 30 minutes exposure
  • 5-10% (50,000ppm – 100,000ppm) – breathing becomes more laborious with headache and loss of judgement
  • >10% (100,000ppm) – when CO2 concentration increases above 10%, unconsciousness will occur in less than one minute. Unless prompt action is taken, further exposure will eventually result in death

Physiological effects of carbon dioxide include:

Drowsiness
Reduced hearing
Mild narcosis
Increased heart rate and blood pressure
Dizziness
Confusion
Headache
Shortness of breath
Dimmed sight
Tremors
Sweating
Unconsciousness

THE BENEFITS OF A CARBON DIOXIDE MONITOR

As CO2 has no taste or smell, it can be hard to detect. This is why CO2 monitors are so important, and a workplace risk assessment may suggest that gas detectors are installed.

Analox offer a wide range of carbon dioxide monitors – from portable monitors like the Aspida and the ACG+ to fixed monitors like the Ax60.

As CO2 is heavier than air, it is recommended that fixed carbon dioxide detectors are not mounted at head height – for example, we recommend that the Ax60 is wall-mounted 450mm off the ground and the repeater unit is placed at head height at the entrance to the room.
