Wind turbine operations and maintenance (O&M) service activity processes and hub-entry procedures generally vary by the wind-turbine manufacturer and model. As a recommended best practice, follow the specific processes and procedures developed by the environmental, health and safety (EHS) manager for each specific wind energy site.
Job-safety analysis or JSA is a tool to aid in preparation for a work activity or equipment operation, end to end from traveling to the wind turbine site through to reversing procedures to return the hub and turbine back to service. The JSA highlights hazards associated with an activity or operation, such as weather events, and enables team members the opportunity to:
- Review relevant environmental, health and safety (EHS) procedures;
- Select the required personal protective equipment (PPE);
- Select the required technical information;
- Select the required tools and equipment, and;
- Select the required materials to complete the activity or operation safely.
As a recommended best practice for JSA, a checklist format helps to ensure that team members first review each work activity or equipment operation, and second take proactive and preventive measures before starting the activity or operation, as opposed to reactive and corrective actions, in the event of an EHS incident, injury or near-miss.
A job-safety analysis or JSA checklist for environmental, health and safety (EHS) risk assessment and risk mitigation includes the following five elements:
- Step #;
- Description of the work activity or equipment operation;
- Potential EHS incident, injury or near-miss;
- Proactive and preventive measures, and;
- Check off or sign off by the team members and by the EHS manager.
For example, numerous weather hazards and weather events pose risks to team members when traveling to and across the wind turbine site, whether on public highways or access roadways. Proactive and preventive measures before starting the activity or operation include reviewing weather events for the round-trip travel time, mobilization, work, and demobilization.
