Engineering and how to mitigate them Every year, electrical hazards cause over 1,000 workplace accidents in the UK, leading to approximately 30 fatalities
E
lectrical engineers face heightened risks due to their work with live circuits and high- voltage equipment. In response to these dangers, the Health and Safety at Work Act 1974 (HASAWA) mandates that employers safeguard their employees’ health, safety and welfare. Non-compliance can result in injuries to those involved and fines, legal action and criminal charges of gross negligence for the employer. This article explores common electrical hazards and how employers can mitigate these risks to meet UK safety legislation.

Electric Shock and Electrocution Electric shock and electrocution are immediate risks for electrical engineers. Employers should implement Lockout/Tagout (LOTO) procedures during maintenance to disconnect power before work begins. The Electricity at Work Regulations 1989 require employers to ensure electrical systems are safe and maintained to protect employees. Therefore, regular inspections along with insulated gloves and dielectric boots, are essential.
Arc Flash and Electrical Burns Arc flashes, explosive releases of electrical energy, can cause severe burns or blindness. These occur when electrical systems malfunction, releasing intense heat and light.
Employers should conduct arc flash risk assessments and ensure equipment is maintained. Flame-resistant PPE should also be provided, and electrical equipment should be labelled with appropriate warnings. Again, regular maintenance and inspections are essential in minimising the risk.
Fire Hazards
In the year ending March 2023, 29 per cent of fires were caused by the ‘misuse of equipment
or appliances.’ Fires can result from faulty wiring or improper use of extension cables. For example, using an electrical extension reel that is still wound on the drum creates an electromagnetic effect that generates heat, causing the cable to ignite.
Employers should ensure electrical systems are correctly installed and regularly inspected.
Falls from Height The Work at Height Regulations 2005 require employers to ensure safe working practices at elevated levels. Electrical engineers often work at heights, whether on scaffolding, ladders, or rooftops, so employers should provide fall protection gear such as harnesses, lanyards and guardrails. Additionally, scaffolding and ladders should be inspected regularly.
Asbestos Risks Electrical work often involves routing cables through walls or ceiling voids that may contain Asbestos Containing Materials (ACMs), which can harm anyone nearby. The Control of Asbestos Regulations 2012 requires employers to manage asbestos risks by consulting the asbestos registers and management planning. Work should be halted if ACMs are suspected.
Confined Spaces Electrical engineers often work in spaces like tunnels or basements, which pose additional hazards, especially when working with electrical systems, as ventilation is poor and escape routes are limited. Employers must implement a permit-to-work system for confined spaces, ensure proper ventilation and have emergency rescue equipment. Workers should be trained in confined space safety and follow Confined Spaces Regulations 1997.
Manual Handling Lifting heavy electrical equipment can cause injuries like strains or sprains. Under the Manual Handling Operations Regulations 1992, employers must assess and minimise these risks. Employers should provide mechanical aids, such as cranes or trolleys, for heavy lifting tasks. Workers should be trained in safe lifting techniques to reduce strain.
Fatigue and Mental Health Fatigue and stress impair focus and increase accident risk. Employers must manage working hours to prevent excessive fatigue under the Management of Health and Safety at Work Regulations 1999. Fatigue management, breaks and mental health support are all essential for maintaining workers alertness and productivity.
Inadequate Training Lack of proper training is a leading cause of workplace accidents. With everything mentioned on this list, employees should be regularly updated on correct practice, employers must provide continuous training, competency checks and regular emergency drills, as required by Section 2(2)(c) of HASAWA. To comply with HASAWA and protect employees, electrical engineering employers must be well-versed in UK Health and Safety regulations. Key safety measures include continuous training, proper PPE, regular inspections and risk assessments. Due to the complexity of regulations, outsourcing health and safety services is recommended. Outsourcing offers expert guidance on risk management and compliance, helping identify hazards that may be overlooked internally and is often more cost effective than in-house H&S.
