Lone Working on Metal and Steel Sites: 5 Scenarios and Safety Measures

A maintenance engineer checking a hydraulic pump beside a rolling line, a stock controller counting steel sections in a quiet storage bay, or a night-shift employee inspecting a separate compressor building?

Different tasks, but the same question: if the worker is injured or becomes unwell, who will notice and how will help reach them?

Lone working on metal and steel sites can occur even when hundreds of people are on the premises. In the steel industry, large production halls, machinery, separate service buildings and multiple levels can put employees beyond their colleagues’ sight or hearing.

The first step is to establish whether each task is suitable for lone working. Some activities require additional people, supervision or specialist rescue arrangements. The following scenarios show where to look and what to consider.

1. Lone Working During Steel Plant Maintenance

An engineer leaves the main production area to inspect a pump, motor or conveyor drive. The equipment may be in a separate service area, with nobody nearby to notice a fall or medical emergency.

A routine inspection can also develop into a repair, therefore, investigating a leak or blockage may introduce hazards that were not covered by the original lone working arrangements.

What to put in place: Define which inspections can be completed alone and when the engineer must stop and request support. Establish who knows the work location, the expected completion time and what happens if contact is lost. Personal safety devices could be helpful to make the work safer, especially if you can get the worker precise location.

Before repair or maintenance begins, apply the necessary isolation and stored-energy controls. HSE’s maintenance guidlines highlights unexpected start-up, pressurised systems and components that could fall.

2. Lone Working in Steel Stockholding and Storage Bays

After dispatch activity slows, a stock controller checks bundles of tubes, steel sections or sheet stock in a separate bay. However, stacked material can obstruct sightlines, while activity in an adjacent loading area may make a call for help difficult to hear.

The assessment needs to cover more than how to contact the worker. Steel storage brings risks from unstable stock, sharp edges, lifting operations and vehicle movements.

What to put in place: Plan stock checks from safe access routes, separate them from incompatible handling operations and define activities the employee must not undertake alone. Needing to climb onto stock or move material to read a label should trigger a review of the task. For the work a worker can do alone, a safety device could also be helpful.

3. Basement and Service-Area Inspections

On some steel sites, cooling-water pumps, pipework and other services are located below the production floor or in separate utility rooms. A worker inspecting these areas may be only a short distance from colleagues but effectively isolated.

Stairs, changes in level and restricted entrances can complicate access after an incident. Communication should be tested along the inspection route, including inside the rooms where work takes place.

What to put in place: Record the route, entry points and expected return time. Check lighting, housekeeping and safe access, and make sure the designated contact knows which basement or service room is involved.

Assess whether any location meets the definition of a confined space and establish suitable emergency arrangements beforehand. A solution to alert the closest person if something happens could be a great tool.

4. Inspections on Elevated Walkways and Platforms

An employee checks equipment from a designated platform above a processing line. From the factory floor, colleagues may be unable to see the worker or identify which staircase reaches them.

Even where the walkway is protected, a worker could become unwell or suffer an injury that prevents them from descending unaided. The response plan therefore needs to address access and evacuation as well as raising the alarm.

What to put in place: Assess whether the inspection can be performed from ground level. Where elevated access is necessary, check the access route, edge protection and arrangements for assisting an incapacitated worker. The work at height guidance by HSE includes planning for emergency evacuation and rescue if you want to have more information.

5. Lone Working During Night Shifts and Shutdowns

A night-shift employee checks an outdoor yard or compressor house while the rest of the team remains in the control room. During a shutdown, contractors may also work in areas normally occupied by production staff.

Daytime arrangements may not work in these conditions. The usual supervisor may be absent, access routes may change and fewer trained responders may be available.

What to put in place: Review lone working arrangements for each shift and shutdown phase. Identify the person responsible for receiving calls or alarms, a backup contact and the action required after a missed check-in.

Include contractors in location and handover arrangements. Check that someone remains responsible until each worker has completed the task or returned.

The Role of Personal Alarms in Lone Worker Safety

Where the risk assessment identifies a need, personal alarms can provide a way to request assistance. Some offer automatic alerts for selected events, such as a detected fall or prolonged immobility, but detection has limitations and should be tested against the intended tasks.

Assess the complete response: can the worker operate the alarm while wearing gloves, can it transmit from the work area, who receives it and can responders identify the location, so you can choose the most suitable solution for your needs.

Improving Lone Working Safety on Metal and Steel Sites

For each task, establish whether lone working is appropriate, how contact will be maintained and how assistance will reach the worker.

In Great Britain, HSE states that employers must manage risks to lone workers, provide training, supervision and monitoring, maintain contact and respond to incidents.

Turn those duties into arrangements employees can use: clear task limits, recognisable locations, named contacts and rehearsed emergency procedures. Test them on the shift and in the places where lone working actually happens. Lone working safety devices can also be very helpful in reducing the risks a worker face.
