Cold Weather Preparation

DOE-STD-1064-94

Ensuring air intakes, windows, doors and any other access which may result in

abnormal inflow of cold air into an area susceptible to freeze damage are

secured.

Heating systems are cleaned, serviced, and functionally tested.

Antifreeze used in cooling systems is checked and replaced as necessary.

Heating system power and temperature controls are protected against

inadvertent deactivation.

Systems requiring or deserving special protection due to hazards or costs

associated with freeze damage have temperature alarms and/or automatic

backup heat sources.

Facility personnel should inspect, test, and stage portable auxiliary heaters and

have identified sources to obtain more, if needed. Personnel should be trained

in the safe use of portable heaters.

The main water supply cutoffs for each critical facility is identified, tested, and

readily accessible to emergency personnel responding to a freeze/thaw

incident.

Outside storage pads and unheated storage areas are inspected to ensure that

there are no materials susceptible to freeze damage.

Implementation of snow and ice removal activities.

Employees are aware of the need to identify and report any suspected

problem with heating or other cold weather protection equipment (i.e., non-

insulated water or process pipes, steam trace heaters valved off, electrical

trace heaters turned off or burned out, broken windows, holes in exterior

walls, etc.).

The removal of freeze protection equipment from service during the seasonal

freeze period should be carefully evaluated.

Wet-pipe sprinkler systems are reviewed for areas susceptible to freezing, and

appropriate actions planned, such as provisions for auxiliary heat; draining and

posting a fire watch; etc.

The availability and use of salt, sand, and "ice-chaser" as needed.

Outside areas are inspected to ensure that gutters and downspouts are

provided where there is a potential for ice buildup that may restrict egress.
