INSTRUCTIONS FOR COMPLETING THIS FORM Section I. Enter general information about the site and job task. Section II. Determine whether any of these operations apply to the job task to be performed. Make note of any special training, permit, certification, and risk assessment requirements. Section III. Identify any human/organizational factors that could impact the ability to perform the work safely. Section IV. :1.

Break the job down into steps - Be as specific as possible. Write each job step in a new row of column A (Activity/Step). It’s a good idea to leave an extra row between steps in case you need them later. Add additional rows to the table as needed, or if completing the JSA on paper, print additional copies of the sheet to accommodate all job steps. 2. Determine the hazards associated with each job step and write them in column B (Hazards). Use the examples of hazards provided below to trigger your thinking about different types of hazards and energy sources. 3. List any control measures that will be taken to ensure that step is done safely in column C (Control Measures). Use the control measure examples and hierarchy provided to trigger your thinking about different types of controls and their effectiveness at reducing risk. Controls toward the top of the table tend to be more effective at minimizing the severity and/or likelihood of an event than the controls toward the bottom of the table. If this job involves a Life Critical Operation, continue to step 4. Otherwise, repeat steps 2-3 for each of the job steps identified, then proceed to step 9. 4. Considering the hazards involved and the control measures that will be in place, determine the worst credible severity of an incident that could result from this job step. Use the severity table provided. Write the severity number in column D (Severity). 5. Considering the hazards involved and the control measures that will be in place, determine the likelihood that an incident will result from this job step. Use the likelihood table provided. Write the likelihood number in column E (Likelihood). 6. Multiply the severity number by the likelihood number and enter the product in column F (Risk). 7. Consider the risk rating against the thresholds provided in the Overall Risk Ratings. i. Very low and low risk ratings of 1-7. This level is generally considered acceptable provided that all control measures are applied. ii. Medium risk ratings of 8-15. Additional control measures should be considered to determine whether it is practical to further reduce the risk. If additional control measures will be implemented, write them in the Control Measures column on the same line or a new line below. Rescore the Severity, Likelihood, and Risk taking into consideration this additional corrective action. iii. High and Very high risk ratings of 16-80. Additional control measures must be considered to determine whether it is practical to further reduce the risk. If additional control measures will be implemented, write them in the Control Measures column on the same line or a new line below. Rescore the Severity, Likelihood, and Risk taking into consideration this additional corrective action. 8. Repeat steps 2-7 for each of the job steps identified. Section V. Provide the name, company, and title of those who prepared and reviewed/approved this form in the signature box provided. The Site/Construction Manager must review and approve any line items that have a High or Very High risk rating before the job may proceed. Additional space is provided for crew members to sign the JSA if desired EXAMPLES OF HAZARDS (Column B) Biological & Environmental Electric Altitude Arc Flash Animal Bite/Sting Buried Utilities Blood-Borne Pathogens Damage to Leads/Cables Contaminated Food/Water Damage to Switches Insect-Borne Disease Energized Circuits/Conductors Pests Inadvertent Energization Poisonous Plants Lack of Isolation/Grounding Precipitation Missing/Damaged Insulation Temperature/Humidity Overhead Lines Unsanitary Conditions Overload of Circuits Weather Stored Energy (Batteries/Capacitors) Wind/Turbulence Water Near Electrical Conductor.
