Emergency Heating (Calor/Butane gas)

[CharlesHarris]

Key to using any space heater indoors, is that you absolutely MUST have a CO detector, and ensure adequate ventilation.

From my disaster response experience monitoring CO in homes where people had used kerosene or LPG heaters, ev en with supposed precautions for ventilation, the CO levels monitored with calibrated instrumentation were unsafe and is these people had slept in dwellings we monitored, without positive pressure ventilation they would have died.
