Employee Injury Risks in Electrical Manufacturing (UK Employers’ Liability Guide)

Introduction

Electrical manufacturing is a high-skill, high-precision environment—but it’s also one where injuries can happen quickly. From machinery entanglement and manual handling strains to chemical exposure and electrical shock, the risks are varied and often linked to everyday tasks.

This guide explains the most common employee injury risks in electrical manufacturing, what UK employers must do to control them, and how Employers’ Liability (EL) insurance helps if a claim is made. If you manufacture components, assemblies, wiring looms, control panels, batteries, chargers, or electronic devices, the principles are broadly the same.

Why electrical manufacturing has a unique risk profile

Electrical manufacturing often combines:

• Fast-moving production lines and automated machinery
• Hand assembly and fine work (often repetitive)
• Soldering, adhesives, solvents, resins, and cleaning chemicals
• Testing, energisation, and fault-finding
• Warehousing, packing, and dispatch

That mix creates overlapping hazards—so controls need to cover both “factory floor” safety and more technical electrical risks.

The most common employee injury risks (and where they happen)

1) Machinery and moving parts

Typical scenarios:

• Entanglement in rotating parts (drills, lathes, winding machines)
• Crush injuries from presses, stamping, or automated pick-and-place equipment
• Cuts from guillotines, shears, and trimming tools
• Pinch points on conveyors and rollers

Common injuries: fractures, amputations, deep lacerations, tendon damage.

Controls that reduce claims:

• Proper guarding and interlocks (and no bypass culture)
• Lockout/tagout (LOTO) for maintenance and clearing jams
• Permit-to-work for higher-risk interventions
• Competency checks for operators and maintenance staff

2) Manual handling and musculoskeletal disorders (MSDs)

Even in modern plants, people still lift, carry, push, pull, and hold awkward loads.

Typical scenarios:

• Lifting reels of cable, transformers, metal housings, or pallets
• Repetitive picking/packing and bench assembly
• Awkward postures at workstations that aren’t set up for the person

Common injuries: back strains, shoulder injuries, repetitive strain injury (RSI), carpal tunnel syndrome.

Controls that reduce claims:

• Manual handling risk assessments and task redesign
• Mechanical aids (lift tables, hoists, pallet trucks)
• Job rotation and micro-breaks for repetitive tasks
• Adjustable benches, seating, and tool balancers

3) Slips, trips, and falls

These are still among the most frequent causes of workplace injury claims.

Typical scenarios:

• Trailing cables/air lines, loose packaging, or offcuts
• Spills from coolants, cleaning fluids, or battery electrolytes
• Poor lighting in storage areas
• Uneven floors, damaged mats, or cluttered walkways

Common injuries: sprains, fractures, head injuries.

Controls that reduce claims:

• Clear housekeeping standards and ownership
• Cable management and designated walkways
• Spill response procedures and suitable absorbents
• Floor condition checks and maintenance logs

4) Electrical shock, arc flash, and burns

Electrical manufacturing can involve live testing, energisation, and fault-finding.

Typical scenarios:

• Working on or near energised equipment without adequate isolation
• Incorrect test setups or damaged test leads
• Poorly maintained test rigs
• Inadequate PPE for arc risk

Common injuries: electric shock, burns, cardiac issues, secondary injuries from falls.

Controls that reduce claims:

• Isolation procedures and proving dead
• Competent persons for electrical work and testing
• PAT and inspection regimes for test equipment
• Clear labelling, barriers, and safe test enclosures

5) Soldering fumes and respiratory exposure

Soldering and rework can expose staff to fumes and particulates.

Typical scenarios:

• Inadequate local exhaust ventilation (LEV)
• Poor workstation layout that pulls fumes into the breathing zone
• High-volume rework without exposure monitoring

Common injuries/illness: asthma, dermatitis, long-term respiratory irritation.

Controls that reduce claims:

• LEV designed for the process and maintained properly
• Fume extraction positioned correctly and used consistently
• COSHH assessments and training
• Health surveillance where appropriate

6) Chemical exposure (solvents, fluxes, resins, adhesives)

Electrical manufacturing often uses cleaning agents, conformal coatings, epoxies, and flux.

Typical scenarios:

• Skin contact from poor glove selection or inconsistent use
• Splash injuries during decanting or cleaning
• Inhalation exposure in poorly ventilated areas

Common injuries/illness: dermatitis, chemical burns, eye injuries, sensitisation.

Controls that reduce claims:

• COSHH assessments with practical controls
• Correct PPE (gloves matched to the chemical, eye protection)
• Closed systems or controlled decanting
• Training that focuses on real tasks, not generic slides

7) Noise and vibration

Some electrical manufacturing processes create sustained noise or use vibrating hand tools.

Typical scenarios:

• Stamping, cutting, grinding, and compressed air use
• Hand tools used for long periods without breaks

Common injuries/illness: noise-induced hearing loss, hand-arm vibration syndrome (HAVS).

Controls that reduce claims:

• Noise assessments and hearing protection zones
• Engineering controls (enclosures, dampening)
• Tool selection and maintenance
• Exposure time limits and monitoring

8) Forklift and workplace transport incidents

Warehousing and dispatch are often where serious injuries occur.

Typical scenarios:

• Pedestrian struck by forklift in shared spaces
• Poor reversing visibility
• Unsafe loading/unloading

Common injuries: crush injuries, fractures, fatal incidents.

Controls that reduce claims:

• Segregation of people and vehicles
• Clear routes, barriers, and marked crossings
• Trained operators and refresher training
• Loading bay procedures and supervision

9) Fire and thermal injuries

Electrical manufacturing can involve heat sources, flammable solvents, and battery-related risks.

Typical scenarios:

• Hot work without controls
• Poor storage of flammables
• Battery thermal runaway risks (where relevant)

Common injuries: burns, smoke inhalation.

Controls that reduce claims:

• Fire risk assessment and drills
• Safe storage and handling of flammables
• Hot work permits and supervision
• Suitable extinguishers and staff training

What UK employers must do (in plain English)

You don’t need to be a legal expert to reduce EL claims—but you do need consistent basics:

• Risk assessments that reflect real tasks and are kept up to date
• Training and supervision that matches the role and the person’s experience
• Maintenance and inspection of machinery, guards, LEV, and electrical test equipment
• PPE that’s suitable, available, and actually used
• Accident reporting and investigation to fix root causes, not just record events

If an incident happens, documentation matters. Clear records of training, maintenance, and risk assessments can make a major difference when a claim is investigated.

How Employers’ Liability insurance responds

Employers’ Liability insurance is designed to cover your legal liability if an employee (or certain labour-only contractors) alleges they were injured or made ill due to their work.

A typical EL policy can help with:

• Compensation awarded to the injured person
• Legal defence costs
• Settlements (where appropriate)

It’s not a replacement for safety management—but it is a key financial backstop if something goes wrong.

Common EL claim triggers in electrical manufacturing

Insurers often see claims linked to:

• Guarding removed or bypassed to “keep production moving”
• Poor manual handling controls for heavy or awkward items
• Inadequate LEV maintenance or failure to use extraction
• Lack of supervision for new starters, temps, or agency staff
• Poor segregation between forklifts and pedestrians

If you recognise any of these, it’s worth tightening controls now—before an incident.

Practical steps to reduce injuries (and strengthen your insurance position)

• Review high-risk tasks quarterly (not just annually)
• Audit guarding and LOTO compliance
• Check LEV test dates and usage behaviour on the floor
• Improve workstation ergonomics for repetitive bench work
• Refresh induction training for temps and agency staff
• Separate pedestrian routes from FLT routes where possible
• Keep near-miss reporting simple and encouraged

When to review your EL cover

Consider a review if you:

• Add new machinery, automation, or production lines
• Start live testing/energisation activities
• Increase headcount or use more agency labour
• Introduce new chemicals, coatings, or soldering processes
• Expand into battery manufacture or high-energy products

FAQs

Is Employers’ Liability insurance legally required in the UK?

In most cases, yes—if you employ staff. There are limited exemptions, but most electrical manufacturers will need EL.

Does EL cover agency workers?

It can, depending on the working arrangement. If you direct and control their work, they may be treated similarly to employees for liability purposes. Always confirm with your broker.

What’s the difference between EL and Public Liability?

EL covers injury/illness claims from employees. Public Liability covers claims from third parties (e.g., visitors, customers) for injury or property damage.

Do I need EL if I only have office staff?

Often yes, if they are employees. Even office environments can have injury risks (slips, trips, workstation injuries).

Can good health and safety reduce premiums?

Strong risk management can help your insurance presentation. While pricing depends on many factors, clear controls and good claims history can support better terms.
