Stress Work Procedure |

1.0
Purpose
This appendix
addresses the procedure used to mitigate potential injury or illness due to
cold stress.
2.0
Scope
This
appendix provides minimum mitigation steps to be used at Jefferson Lab to
reduce injuries or illnesses caused by cold stress. Overarching
responsibilities and expectations are provided in ES&H Manual Chapter 6670 Heat and Cold Stress
Mitigation Program.
There
are no known controlled work environments with temperatures considered cold
stress areas at Jefferson Lab. Contact Industrial
Hygiene for more
specific information on cold stress or further instructions if workers will be
exposed continuously to extreme temperatures as listed in the Increased Danger
or Great Danger areas of the Windchill Chart in Section 4.0.
Subcontractors follow this procedure
or a Jefferson Lab approved procedure.
This appendix does
not address specific hazards or potential injuries from sudden exposure to
cryogenic materials (see ES&H Manual Chapter 6550 Cryogenic
Safety Program).
These mitigation
steps are used when Wind Chill air temperature reaches 37oF.

Responsibilities
NOTE: Management
authority may be delegated to a task qualified Jefferson Lab employee at the
discretion of the responsible manager. Refer to ES&H Manual Chapter 6670 Heat and Cold Stress
Mitigation Program
for a list of overarching responsibilities for this program.
3.1

·
Eliminate sources of cold stress where
feasible (see ES&H
Manual Chapter 6670 Appendix T3
Assessment of Thermal Hazards).
·
Provide heat and cold stress
prevention guidance for employees working under these
conditions. Guidance may be requested from Industrial Hygiene or Occupational
Medicine.
· Provide appropriate rest periods for employees. Consult Industrial Hygiene for appropriate work/rest schedules.
·
Familiarize
workers with cold stress, its symptoms1, and prevention.
·
Plan
and schedule work to minimize worker exposure to extreme temperatures.

4.0
Process Steps
These stages are implemented for
outside work.
Stage
1: Wind
Chill < 37oF
Step
1: Monitor the weather: all
staff should monitor local weather predictions [http://www.weather.gov/bgm/heatindexforecasts]
to plan accordingly. When cold
conditions are anticipated to potentially cause a thermal stress hazard, ES&H
division will send notifications to staff.
Step
2: ES&H
Professional/Supervisors/TRs
·
Inform
workers of cold stress condition as necessary.
·
Familiarize
workers with cold stress, its symptoms1, and prevention.
·
Confirm
provisions for fluid replacement and shelter procedures as appropriate.
Step 3: Upon notification, Jefferson Lab Staff:
·
Drink
ample amounts of water – more than your sense of thirst indicates.
·
Wear
layered clothing.
·
Recognize
personal risk factors. If at higher risk than normal, advise your supervisor
and Occupational Medicine, and limit work activities. If taking medication, be
familiar with its risk potential.
·
At
first signs of cold illness, seek a warmer area.
Stage 2: Wind Chill < 16oF
These conditions
will be assessed by management and additional actions will be determined as
conditions warrant.
