Step 1: Review each “Hazard” with identified safety “Controls” and determine RAC (See above)
“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 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.

Get as close to the load as possible. Avoid picking up heavy
objects placed below your knees.
Keep your back straight when reaching to lift an object.
Tighten your stomach muscles to keep your spine from twisting
while lifting a load. Never twist at the waist while carrying a load.
Bend with your knees not your back.
Stretch and loosen up before work. Change direction by moving
your feet not your hips.
Look ahead to make sure the path is clear.
Set the load down if it becomes unstable or too heavy.
Remember to push not pull whenever possible.
Use lifts, hoists or dollies to move loads when possible to avoid
manual lifting.
