Locate your device

Potential sources of carbon monoxide are wood-burning stoves, gas boilers and fires, gas hobs, oil and coal-burning appliances, portable gas heaters, barbecues etc.

    additional apparatuses:

    • Where you spend the most tme
  • In case of bedsit (single room serving as both sitng room and bedroom): locate the apparatus as far as possible from the cooking appliances and near the sleeping area.
  • In rooms with a fuel-burning appliance:
    • Between 1-3 m distance away from the potential source
    • If there is a partition in the room: at the same side of the partition as the potential source
    • On the wall:
      1. Close to the ceiling, but at least 150 mm from the ceiling
      2. Higher than the height of any door/window
  • In rooms without a fuel-burning appliance (such as sleeping rooms/hallways:
    • Relatively close to the breathing zones of occupants

  • 200-300 PPM Severe headache, nausea, impairment in limb movements
  • 300-400 PPM Severe headache, irritability, confusion, impairment in visual acuity, nausea, muscular weakness, dizziness, weakness
