During operation, the SHS produces harmful carbon monoxide (CO) and other gases.
Carbon monoxide is a colorless, odorless, and tasteless gas. Mild cases of carbon monoxide
poisoning can cause symptoms such as nausea, dizziness or headaches. Severe cases of
carbon monoxide poisoning can result in brain damage, heart damage or death. Remember
that although CO has no telltale odor, it may mix with other odors which mask its presence;
therefore, CO can be present within a mix of seemingly harmless odors.
To prevent CO poisoning, ensure that the SHS exhaust stack sections fit together snugly and
that the exhaust gases are properly vented through the roof of the shelter.
The best way to prevent CO poisoning is to keep the SHS in good working order. Ensure that
all possible sources of CO leakage have been repaired and that the operating space is well
Some metal components of SHS may have sharp edges. Be careful when handling and
assembling the SHS to prevent cuts.
