Safety, Human Physiology, and Electricity and Legislation

Safety and Electricity

  • Electrical Safety: It is critical to consider safety measures when dealing with electricity. These can be simple precautions like keeping water away from electrical appliances or circuitry, to strictly adhering to the safety rules and regulations defined by governing bodies.
  • Grounding: This is an essential safety measure used in electrical circuitry. A ground provides a safe path for electrical current to travel in case of a fault, thus protecting individuals from electrical shock.
  • Insulation: Good insulating materials such as rubber or plastic are used in wiring systems to prevent accidental contact with live conductors, reducing the risk of electrical shock.

Electrical Hazards and Human Physiology

  • Electrical Burns: These occur when an electrical current passes through the body. They can cause severe damage to skin, tissues, and organs.
  • Electrical Shock: When the human body becomes part of an electrical circuit, electrical shock could occur. The severity of the shock can range from minor discomfort to cardiac arrest, depending on the strength of the current and route it takes through the body.
  • Muscle Contractions: Electrical currents can cause involuntary muscle contractions, which in severe cases can cause falling, or prevent the person from releasing the electrical source, leading to prolonged exposure.

Legislation Related to Electricity

  • Electricity at Work Regulations 1989: This statute was designed to protect people who work with electrical appliances and infrastructure. It provides clear rules about proper maintenance of electrical equipment and safe working practices.
  • Consumer Protection Act 1987: Protects consumers by enforcing strict controls on electrical goods. Manufacturers must ensure that any electrical products they produce are safe for use, and customers have the right to return goods that are shown to be unsafe.
  • Building Regulations Part P: This regulation specifies that all major electrical work performed in homes must be carried out or inspected by a certified professional. This ensures the safety and quality of electrical installations.
