• Current (I): The flow of electric charge measured in amperes (A).
• Resistance (R): The opposition to the flow of current, measured in ohms (Ω).

Always remember that high voltage can cause severe injuries or death, and even a small current could be lethal under certain conditions.

Common Electrical Hazards

You’ll frequently encounter various electrical risks on the job. Being aware of these risks is crucial:

1. Electric Shock: Accidental contact with live parts can cause muscle contractions or a heart attack.
2. Arc Flash/Blast: A sudden discharge of electricity through air, resulting in an explosive release of energy, which can cause burns.
3. Fire: Faulty wiring or overloaded circuits can cause electrical fires.

Preventative Measures:

• Use insulated tools and wear rubber-soled boots.
• Maintain a safe distance from live electrical parts.
• Regularly inspect electrical equipment for damage.

Electrical Safety Regulations

In the UK, the Electricity at Work Regulations 1989 outlines the responsibilities of both employers and employees to maintain safety standards while handling electrical systems. Key components of these regulations include:

• Risk Assessment: Identify potential electrical hazards before commencing work.
• Maintenance: Keep electrical systems and protective equipment in good working order.
• Training and Competence: Ensure that individuals working with electricity have adequate training.

Your Responsibilities:

• Follow all relevant safety procedures and guidelines.
• Report any electrical hazards to your supervisor.
• Never work on live systems unless absolutely necessary and you are qualified to do so.

Staying informed and vigilant is your best defence against electrical accidents. By understanding these key aspects of electrical safety, you will be better equipped to work safely and efficiently in your trade.

Risk Assessment and Management

Before you begin any electrical work, it’s essential to conduct a thorough risk assessment, implement effective control measures, and follow safe isolation procedures. This approach minimises the risk of injury or damage during electrical tasks.

Conducting a Risk Assessment

When conducting a risk assessment, initially you must identify potential hazards associated with the electric work. Evaluate the risks by considering the severity and likelihood of an adverse event occurring. To document your findings, use a risk assessment table like the one below:

Hazard	Persons at Risk	Likelihood	Severity	Overall Risk
Exposed live wires	Electricians, other tradespeople	High	High	High
Faulty equipment	Tradespeople, clients	Medium	High	High
Overloaded circuits	All site personnel	Low	High	Medium

Once assessed, create a plan to manage these risks, incorporating suggestions and regulations provided by the Health and Safety Executive (HSE). Make sure this plan is accessible and understood by all team members.

Implementing Control Measures

After identifying the risks, you must implement control measures to mitigate them. Prioritise the hazards and tackle those with the highest risk first. Control measures can include:

• PPE: Appropriate personal protective equipment such as gloves, goggles, and fire-retardant clothing.
• Training: Ensure that you and your team have up-to-date knowledge on electrical safety standards.
• Equipment checks: Regularly inspect and maintain your tools and machinery to ensure they’re in safe working condition.

It’s crucial to review and update your control measures periodically, as working environments and legal requirements can change.

Safe Isolation Procedures

To manage risks effectively, safe isolation is a key procedure every electrician must implement. Below is a checklist for safe isolation:

1. Notify: Inform all affected parties that you’re about to isolate power supplies.
2. Identify: Correctly identify the circuits or equipment set to be isolated.
3. Isolate: Switch off the power supply using an approved isolation device.
4. Lock Out: Apply lockout devices to prevent accidental re-energising.
5. Verify: Use appropriate test equipment to verify the absence of voltage.
6. Earthing: If required, apply earthing devices to discharge residual energy.

Following these steps ensures that the work area is completely safe from unintended electrical power, protecting you and others from electrical hazards during work activities.

Protective Measures and Best Practices

Adherence to protective measures and best practices is essential in mitigating risks associated with electrical work. Below are critical strategies for ensuring safety.
