Glovebox Fire Protection

DOE-STD-1066-99

15. GLOVEBOX FIRE PROTECTION

15.1 Scope

15.1.1

Gloveboxes and Hot Cells

15.1.1.1

This section provides fire protection requirements for the design and

construction of all new gloveboxes. It also addresses extinguishing

methods, ventilation protection features, and general operating

safeguards.

15.1.1.2

This standard is not intended for hot cells, although some design

principles in this document may prove useful if similar hazards are present.

Consult a qualified fire protection engineer before applying these criteria

to hot cells.

15.1.1.3

If the use of the glovebox is to change or the glovebox is removed from

service, an FHA should be performed to evaluate the potential fire hazards

associated with the change.

15.1.2

Existing Glovebox Installations

These criteria apply to existing glovebox installations when an FHA demonstrates

conditions that warrant their application, or when determined by the AHJ.

15.1.3

Table-Top Gloveboxes

Sections 15.3 and 15.5 do not apply to single, table-top, or mobile-type gloveboxes

unless the potential fire hazards associated with these units warrant applying these

sections to those installations.

15.1.4

Automatic Fire Protection Required

An automatic fire suppression or inerting system is required in all new gloveboxes

unless an FHA concludes that such a system is not warranted, and except as noted

in 15.1.3 above.

15.2 Glovebox Construction

15.2.1

Noncombustible Materials

15.2.1.1

Gloveboxes should be constructed of noncombustible materials. The most

common materials used are stainless steel and glass.

15.2.1.2

If the atmosphere and/or process within the glovebox is incompatible with

the construction material of the box, an epoxy resin with inorganic fillers

may be used to coat the interior metal surfaces of the glovebox. Where

plastic linings are used for this purpose, the glovebox enclosure should be

protected by either an automatic fire suppression system or an inert
