When used in a hazmat incident, shelters may come in
contact with substances
‘
hazardous to health
’
. Should this
happen, they should be thoroughly cleaned to prevent
contamination of personnel. Operators should be aware of this
risk, and wear appropriate personal protection to avoid
coming in contact with these substances. On scene
coordinators must manage and be completely responsible
herein.

Shelters are fitted with an over pressure valve on the
inflatable structure, to prevent the unit from over-inflating and
possibly bursting. This valve is fully automatic in operation and
must not be blocked or adjusted in any way. If using
compressed air to inflate unit, an operator must stand by at all
times and immediately turn off compressed air source when the
ove
r pressure valve is activated as noted by the “hissing”
sound of escaping air.
9. When deflate, be sure all the people inside the shelter had
left, otherwise it may cause asphyxia.
TEMPERATURE USE GUIDELINES
At different temperatures, the compressed air in the air berm
expands as the temperature rises and shrinks as the
temperature decreases, so temperature affects the use of the
shelter.
COLD WEATHER USE:
Recommended for use in temperatures to -20 degrees C (-4 degrees
F) Fully inflate to the point of the over pressure valve almost being
activated (if activated cease air fill immediately) if being used in
extreme cold weather since the cold air will actually contract
inside the berms and the air berms may feel slightly
‘soft’ to the
touch.
