Work Equipment

Overview

Electricians rely on a wide range of work equipment every day, from hand tools and power tools to specialist test instruments and access equipment. The safe use, regular inspection, and proper maintenance of all work equipment is a legal requirement under the Provision and Use of Work Equipment Regulations 1998 (PUWER).

Work equipment injuries remain one of the most common causes of accidents in the construction industry. Understanding PUWER, inspection schedules, and the specific precautions for different tool types is essential.

At a Glance: This topic covers PUWER 1998, equipment inspection requirements, abrasive wheel safety, portable power tools, and hand tool safety. Focus on PUWER’s key requirements, the three-tier inspection approach, abrasive wheel rules, and 110V CTE for construction sites.

PUWER 1998

The Provision and Use of Work Equipment Regulations 1998 apply to all equipment used at work, from a simple screwdriver to a large piece of plant. PUWER applies to employers, self-employed persons, and anyone who controls the use of work equipment.

Key PUWER Requirements

Requirement	What It Means
Suitable	Equipment must be appropriate for its intended use and the conditions
Maintained	Kept in an efficient state, in efficient working order, and in good repair
Inspected	Checked at suitable intervals by a competent person, with records kept
Training	Users must receive adequate information, instruction, and training
Guarded	Dangerous parts of machinery must have appropriate guards and protection devices
Controls	Must have suitable start, stop, and emergency stop where necessary
Marked	Must display appropriate health and safety warnings

Key Fact: PUWER covers equipment that is owned, hired, or borrowed. The duty to ensure equipment is safe applies regardless of who owns it. If you bring your own tools to site, they must still meet PUWER standards.

Equipment Inspection

All work equipment must be inspected at appropriate intervals to ensure it remains safe. The inspection regime has three tiers, each with a different purpose and frequency.

The Three-Tier Inspection Approach

1. Pre-use checks — Visual inspection before every use by the operator. Check for damage, wear, missing guards, and correct function.
2. Formal visual inspection — Regular documented inspection by a competent person at set intervals. More thorough than a user check.
3. Thorough examination — Detailed inspection and testing at intervals specified by regulations or manufacturer guidance. May involve stripping down equipment.

PAT Testing on Construction Sites

On construction sites, portable electrical equipment (110V) typically requires formal inspection and PAT testing every 3 months. Equipment used in harsher environments or subject to more wear may need testing more frequently.

Key Fact: Equipment that fails any inspection must be immediately taken out of service, clearly labelled as defective, and either repaired by a competent person or disposed of. Never continue using faulty equipment.

Keeping Records

Records of all formal inspections must be kept and made available for review. These records provide evidence of compliance and help track equipment condition over time.

Abrasive Wheels

Abrasive wheels (angle grinder discs, cutting discs, grinding wheels) present serious hazards including disc burst, entanglement, and flying debris. Specific legal requirements apply.

Key Rules for Abrasive Wheels

• Only trained and competent persons may mount (change) abrasive wheels — this is a specific legal requirement under PUWER
• The maximum speed rating of the disc must be equal to or greater than the spindle speed of the machine
• Guards must be correctly fitted and positioned — never remove or adjust guards to get a better angle
• Visually inspect every disc before fitting — never use a cracked, chipped, or damaged disc
• Use the correct disc type for the material (stone discs for masonry, metal discs for steel)
• The ring test can check vitrified wheels for cracks — a clear ring indicates soundness
• Wear appropriate PPE: eye protection, hearing protection, gloves, and dust mask

Key Fact: The requirement for a trained and competent person to mount abrasive wheels is one of the most commonly tested points in this topic. Not just anyone can change a disc — this requires documented training.

Speed Rating Safety

Scenario	Result
Disc speed rating higher than machine speed	Safe to use
Disc speed rating equal to machine speed	Safe to use
Disc speed rating lower than machine speed	Dangerous — disc may burst

Portable Power Tools

Power tools present hazards including electric shock, cuts, entanglement, noise, vibration, and projectile debris. Safe use requires discipline and awareness.

Pre-Use Inspection

Before every use, check the tool body, cable, plug, switch, and all accessories for visible damage. If anything is damaged, do not use the tool — label it as defective and report it.

Safe Use Requirements

• Correct tool selection — use the right tool for the job with appropriate power and speed ratings
• Training and competence — operators must be trained for each specific tool
• Guards in place — never remove, bypass, or disable safety guards
• PPE — wear eye, hearing, and hand protection as required
• Secure the workpiece — clamp or secure work before cutting, drilling, or grinding
• Isolate before adjusting — disconnect from supply before changing blades, bits, or accessories

Voltage Requirements

Environment	Required Supply	Maximum Voltage to Earth
Construction sites	110V CTE	55V
Offices, workshops	230V with RCD protection	230V
Wet or confined spaces	Battery powered or extra-low voltage	Varies

Key Fact: On construction sites, portable tools must use 110V CTE supply. The centre-tap means the maximum voltage to earth is only 55V, greatly reducing the risk of fatal shock compared to 230V mains.

Battery-Powered Tools

Cordless tools eliminate electric shock risk from the supply and remove trailing cable trip hazards. However, lithium-ion batteries require proper storage and charging to prevent fire risk, and mechanical hazards from moving parts remain.

Hand Tool Safety

Hand tools cause a significant number of injuries despite appearing low-risk. Complacency is the biggest danger.

Key Precautions

• Use the correct tool for the task — never improvise or force a tool to do something it was not designed for
• Keep cutting tools sharp — blunt tools require more force and are more likely to slip
• Inspect before use and replace any damaged or worn tools
• Use insulated tools (rated to 1000V AC) when working on or near electrical circuits
• Store tools securely to prevent them falling from height or injuring others
• Carry tools in a proper tool belt or bag, not loose in pockets

Key Fact: Insulated tools rated to 1000V AC must be used when working on or near live electrical equipment. Standard tools do not provide electrical protection.

Safety Considerations

• Inspect everything before use — pre-use checks are your first and most important line of defence
• Report defective equipment immediately — label it, remove it from service, and tell your supervisor
• Use the right tool for every job — improvisation causes accidents
• Check PAT test dates on all portable electrical equipment before use
• Disconnect before adjusting — always isolate power tools before changing accessories
• Store tools securely at all times, especially when working at height
• 110V CTE on construction sites — never use 230V tools unless specifically risk assessed with additional RCD protection
• Follow manufacturer instructions for all equipment, including maintenance schedules and operating limits

Exam Tips

Exam Tip: Know the key PUWER requirements: suitable, maintained, inspected, training, guards, controls, and markings. Questions often list these and ask you to identify which one applies.

Exam Tip: Understand why 110V CTE is used on construction sites and that the maximum voltage to earth is 55V, not 110V.

Exam Tip: The three-tier inspection approach (user check, formal visual, combined test) and PAT testing intervals are frequently tested.

Exam Tip: A visual check before every use is the operator’s personal responsibility. This is the most basic and most important inspection.

Exam Tip: The rule that only trained and competent persons may mount abrasive wheels is a very common exam question. Remember that speed ratings must also be checked.

Exam Tip: Know what to do with defective equipment: stop using it, label it as defective, report it, and remove it from service. This sequence appears in many questions.
