Relocatable structures should not be placed over control valves, access ways to
underground utilities, utility corridors, gas mains, or water mains.
Relocatable structures may be placed above those utility lines that service
the structure itself.
Relocatable structures should not be placed beneath vital power lines or lines over 600
volts such that a fire in the structure could damage the lines. Such structures should also
not be placed under other vital utilities, such as communication cables and inerting gas
lines, unless the relocatable structure is protected by an automatic fire suppression
system. Service conductor clearances and disconnects should be in accordance with
Site location(s) for relocatable structures should be evaluated for wildland fire exposures.
Where a significant fire risk exists, appropriate fire resistive building materials and/or other
methods of protection should be utilized as determined by the cognizant fire protection
Relocatable structures should not be placed closer than 50 feet (15 meters) to a fire
hydrant. (See also, paragraph 8.3.)
6.3 Cargo Containers
Cargo containers should be limited to stacks 2-high unless otherwise approved by the cognizant
fire protection engineer. The arrangement of cargo containers, which may not meet other industry
fire safety standards, should reflect the fire hazard of contents, the risk to personnel, value, and
access for emergency responders.
