£140,000 Fine After Apprentice Injured: The Critical Importance of Machinery Guarding and Electrical Safety in Training Workshops

Training workshops are designed to be the foundational proving grounds for the next generation of engineers and fabricators. They must be the safest, most stringently controlled environments on any industrial site. Unfortunately, a recent prosecution by the Health and Safety Executive (HSE) has highlighted the devastating consequences when basic statutory compliance is ignored.

On 8 November 2024, a 17-year-old apprentice at MTL Advanced Ltd in Rotherham suffered a severe crush injury to his thumb while operating a metal-cutting guillotine. Following a thorough investigation, the HSE discovered a large gap in the machine's bed that allowed direct access to dangerous moving parts. Shockingly, the company had failed to identify or rectify this critical risk even after the incident occurred.

On 30 March 2026, the company pleaded guilty to breaching Regulation 11(1) of the Provision and Use of Work Equipment Regulations 1998 (PUWER). They were handed a severe £140,000 fine and ordered to pay over £5,000 in costs at Sheffield Magistrates' Court.

As a professional firm specialising strictly in commercial and industrial electrical compliance, TMUK Group Ltd views this incident as a stark warning. The HSE's wider inspection of the premises revealed systemic failures that extended far beyond mechanical guarding—including direct access to live electrical parts. This is an immense red flag for any facility manager: where mechanical safety fails, lethal electrical hazards are almost certainly present.

The Root Cause: Systemic Failures in Inspection and Maintenance

The HSE investigation uncovered that the guillotine was located in a dedicated Apprentice Training Workshop. Young workers are inherently at a higher risk during their first six months of employment due to a lack of industrial awareness. Placing them in an environment with unguarded machinery and exposed live electrical components is a catastrophic failure of a company's duty of care.

HM Principal Inspector of Health and Safety, Chris Tilley, stated: "Had this machinery been effectively guarded, this injury would never have happened."

Furthermore, the discovery of exposed live electrical parts during the HSE's subsequent inspection indicates a complete breakdown of Planned Preventative Maintenance (PPM). Under the Electricity at Work Regulations 1989 and BS 7671:2018+A3:2024, all electrical systems must be maintained to prevent danger. An exposed live part in a metal fabrication workshop is an immediate Code C1 (Danger Present) observation, posing a lethal risk of electrocution or arc flash.

Statutory Responsibilities for Industrial Environments

To fulfil your statutory duty of care and protect both your workforce and your business from prosecution, your safe systems of work must rigorously enforce the following:

• Routine PUWER Inspections: All workshop machinery must be assessed regularly to ensure guards, emergency stops, and interlocks are fully operational and cannot be bypassed.
• Strict Electrical Compliance (EICR): Industrial workshops require frequent Electrical Installation Condition Reports. You can verify the maximum intervals for your specific facility using our EICR Frequency Guide.
• Safe Isolation Protocols: Before clearing blockages or maintaining machinery, equipment must be mechanically and electrically isolated. Establish strict Lock-Out/Tag-Out (LOTO) procedures.

Interactive TMUK Engineering Tools for Workshop Safety

Safety is not achieved by guesswork; it is built through strict, verifiable engineering protocols. TMUK Group Ltd provides a suite of free, mobile-ready tools designed to assist duty holders, supervisors, and engineers in maintaining absolute compliance on the factory floor:

• Digital Permit to Work Issuer: Digitally issue, document, and track formal lock-off isolations and Limitations of Access to ensure machinery is entirely dead before maintenance begins. Launch Tool ➔
• EICR Defect Classification Lab: Train your supervisors and maintenance staff to correctly identify and code electrical faults (like exposed live parts) before the HSE does. Launch Tool ➔
• Maximum Zs Calculator: Ensure your workshop's protective devices (MCBs, RCBOs, Fuses) will trip within the statutory 0.4 s or 5 s disconnection times during an earth fault. Launch Tool ➔
