Health, safety and wellbeing for Energy Storage System Makers: high-voltage habits, yard work and site travel
High-voltage work needs strict habits, and site delays push extra work onto the yard crew. Health, safety and wellbeing here covers isolation, lifting and the strain of constant travel.

Integration work involves large battery packs, high-voltage wiring and heavy cabinets. A technician working a few extra hours to meet a delayed dispatch may skip a step in isolation or test a circuit without a second person. Yard crews lift containers and cabinets with cranes and forklifts under time pressure. Commissioning crews travel for days, sleep little and work long hours on site, and fatigue and stress rise. Nobody tracks their wellbeing until someone burns out.
Good looks like firm habits. Isolation and testing follow a written sequence with a second person present. Lifts have a plan and a named signaller. Dispatch dates move when work cannot be done safely. Site crews have rest rules and a way to report strain. Safety officers are involved in planning and not just in reviewing incidents. Wellbeing is a topic at the project meeting.
How to set it up
1. Write the isolation and test sequence
For high-voltage work, write the steps in order, including lock-off, test for dead and a second-person check. Put it at the workstation and on the site kit.
2. Plan lifts and yard movements
Define who signals, who rigs and where people stand for each major lift. Keep forklifts and people apart in the yard.
3. Build safety into dispatch planning
When a site delay compresses yard work, let the safety officer and project lead decide together what can be done safely. Never pass the delay onto the crew without a review.
4. Set rest and travel rules for site crews
Limit continuous long shifts on site, plan rest after travel and agree who to call if a person is unwell. Our health, safety and wellbeing service can help shape this.
5. Review incidents and strain monthly
Read near-misses and talk with crews about workload. Act on patterns, such as repeated rushed handovers or the same person always travelling.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Read the last month's near-miss notes and see how many involved high-voltage or lifting.
- Ask three technicians to explain the isolation sequence from memory.
- Check how many days in a row the busiest commissioning engineer has worked.
- Count dispatch delays in the last quarter that led to extra yard hours.

Questions owners ask
Make the sequence non-negotiable and give the safety officer authority to stop work. Plan the schedule so it does not rely on skipped steps.
The project lead and the HR contact together. Ask how travel and long days are affecting people, and adjust postings and rest.
Both need the core rules. Yard crews need more on lifting and forklifts, and site crews more on isolation, travel and working in unfamiliar places.
