Location Restrictions

DOE-STD-1088-95

Exception 2:

Tents and other fabric-type structures should comply with the separation distances

and exposure protection requirements of NFPA Standard 80A.

In all cases, the required separation distance should be based on the "worst case" between the

structures, such as when structures are positioned on an angle. Required distances to separate

permanent buildings or facilities from relocatable structures should be determined in a similar

manner. Due to the many factors that must be considered for permanent buildings, NFPA 80A

should be used to establish their separation distance.

Exposures presented by exterior canopies, connecting walkways, etc. should also be considered

when determining separation distances and protection features.

There should be no storage of combustible or hazardous materials between the relocatable

structure and the exposed building(s).

6.2 Location Restrictions

Relocatable structures should be placed so emergency vehicles can operate within 100

feet (30 meters) of the structure. The space between the structure and the road should be

free of natural obstructions that would prevent or severely restrict access by emergency

responders. Security barriers should be designed in a manner that permits emergency

access. Landscaping and similar non-essential obstructions should not restrict emergency

access.

Relocatable structures should not be located where they impede or otherwise hinder

personnel egress or ingress to, or within, other facilities or structures.

Relocatable structures should not be located where they impede or otherwise hinder the

access of emergency response vehicles to other facilities or structures.

Relocatable structures should not be placed inside permanent facilities that do not have

sprinklers unless a fire hazards analysis demonstrates that there is no significant increase

in fire risk to the facility. Structures that are placed inside permanent facilities should be

protected with the same level of fire protection as provided for the permanent facility.
