“Probability” is the likelihood to cause an incident, near miss, or accident and
identified as: Frequent, Likely, Occasional, Seldom or Unlikely.
“Severity” is the outcome/degree if an incident, near miss, or accident did occur and
identified as: Catastrophic, Critical, Marginal, or Negligible
Step 1: Review each “Hazard” with identified safety “Controls” and determine RAC
(See above)
Step 2: Identify the RAC (Probability/Severity) as E, H, M, or L for each “Hazard” on
AHA. Annotate the overall highest RAC at the top of AHA.
E = Extremely High Risk
H = High Risk
M = Moderate Risk
L = Low Risk
HAZARDS
JOB STEPS
ACTIONS TO ELIMINATE OR MINIMIZE HAZARDS
Identify times and points where hypothermic Hypothermia, and related conditions, 1. Monitor conditions: Temperatures and wind speeds are monitored at least
Notes:
conditions are present
possible shock and possible death
every four hours using site weather station and/or applications on smart phones
Notes:
RAC
H seldom
2. Provide heated areas: Sufficient "hot boxes" with heating sources and fuel are
maintained in the work zones for adequate coverage for all personnel at hand.
3. Availability of impermeable layer for torso and limbs: An impermeable
jacket/coat is recommended for all personnel
4. Availability of thermal gloves. Each crew member will be issued thermal gloves
and will turn in when replacement is necessary.
5. Monitor for Cold injuries/Stress: At least 1 person per shift trained in first aid,
and in recognizing symptomatology of hypothermia injuries.
6. Provide for hydration: Sufficient potable water in insulated containers to permit
proper hydration. Hydration needs frequently increase in wind and cold.
7. Operations in Wet Conditions: Recommend that all outdoor personnel have a
change of clothing available, particularly those working around wet conditions.

8. Work/Rest Cycle: Once temperatures reach the action points of the wind chill
tables, personnel shall be rotated at the intervals cited, generally 15 minutes in
exposure followed by heat breaks.
RAC
9. Handling of cold material: Due to the impossibility of covering metal bars and
handles, especially the Tremie racks and pipes, we are providing thermal gloves as
well as other gloves, as deemed usuable for the crews
10. Provide heated areas: Hot huts should be moved as to block as much wind as
possible, both to the work point and to the hut heaters
11. Eye Protection: Protective eyewear is a 100% requirement on site, especially in
wind areas. Double protection my be called for at the discretion of the SSHO or
SSM.
12. Training/Compliance: Full compliance with 06.i.13 is directed and maintained.
Supervisors shall be instructed as to the scope of 6.i.13, usually as a safety item at
the supervisors meeting.
