SPACE HEATER SMALL (SHS)
OPERATION UNDER UNUSUAL CONDITIONS
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.
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
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 ventilated.
OPERATION IN DUSTY OR SANDY CONDITIONS
Care should be exercised when using the SHS in sandy or dusty conditions to ensure that fuel tank and
burner assembly remain free of sand. To prevent sand from contaminating the fuel tank and burner
assembly, leave lid and lid assembly closed all times.
Keep lids installed tightly on all fuel containers.
OPERATION IN COLD CONDITIONS
Severe injury may occur to personnel handling metal parts without protective gloves when
temperatures are below freezing. Skin may freeze upon contact and tear from the flesh.
Do not allow fuel to come in contact with bare skin. Even though fuel does not freeze, it is
extremely cold and will burn exposed skin on contact. Wear protective gloves whenever
handling or working with liquid fuel.
