TABLE 1: C-D Determine Exposure and Occurrence Select the description that best matches the likelihood of exposure and occurrence of the hazard. C. Likelihood of Exposure D. Likelihood of Occurrence

1. Continuous 2. Frequent (daily) 3. Occasional (once/week) 4. Unusual (once/month) 5. Rare (few per year) 6. Very rare (yearly or less)

Consequences

1. Very likely (has happened is expected) 2. Likely (probable – it could happen again) 3. Rare (seldom but possible) 4. Very rare (very seldom, but possible) 5. Very unlikely (slight possibility 6. Practically Impossible

Step 1: Identify the Job and tasks requiring analysis Step 2: Identify the steps in A. Step 3: Determine the hazards and potential accidents Step 4: Perform a Risk Assessment Determine exposure/occurrence (Table 1) Determine Probability (Table 2) Determine Risk (Table 3-4) Determine Risk Rating (Table 5) Step 6: Identify Controls Required Step 7: Evaluate existing Programs Step 8: Develop action plan

TABLE 4: Determination of Risk Locate the number (1-5) down the left side of the chart that describes the Consequences (from table 3). Locate the letter that relates to Probability (from table 2). The box where Probability meets Consequences is the Risk Rating Number Probability

TABLE 2: E – Probability Locate the number (1-6) down the left side of the chart that describes the likelihood of exposure of the hazard. Locate the number that describes the likelihood of the occurrence (1-6). The box where they meet is the probability rating.
