OPERATION IN UNUSUAL ENVIRONMENT/WEATHER CONDITIONS
GENERAL
Refer to Operation Under Usual Conditions (WP 0005), for specific operating instructions, and use this
work package for further instruction if operating the heater in unusual conditions. Read all sections which
apply to the conditions to which your heater will be exposed.
Sections are broken down into general solid and liquid fuel operation conditions and specific solid or liquid
fuel operation conditions.
WARNING!
Carbon Monoxide
During operation, the SHA 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 SHA 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 SHA in good working order. Ensure that
all possible sources of CO leakage have been repaired and that the operating space is well
ventilated.
OPERATION IN DUSTY OR SANDY CONDITIONS
Solid and liquid fuel operation. Care should be exercised when using the SHA in sandy or dusty
conditions to ensure that all connectors and fittings remain free of sand. To prevent sand from
contaminating the connectors and fittings, leave the hoses in either the stored or operating configuration at
all times.
Solid fuel operation only. None.
Liquid fuel operation only. Before making connections, inspect fuel line ends and fuel flow control
fittings for dust or sand fouling.
Keep lids installed tightly on all fuel containers.
