Physical safety Revision Notes

Electrocution occurs when an electric current passes through the body, potentially causing serious injury or death. In ICT environments, this risk mainly arises from two situations: liquid spills near electrical devices and contact with live wires.

For example, if a cup of water is accidentally knocked over onto a laptop charger or power strip, the liquid can conduct electricity and cause a shock. Similarly, exposed or damaged cables with live wires can cause electrocution if touched.

To prevent electrocution, always keep liquids away from electrical equipment. Use spill-proof containers and maintain a dry workspace. Regularly inspect cables and plugs for damage, and replace any faulty components immediately. Never attempt to touch or repair live wires without proper training and equipment.

• Electrocution results from electric current passing through the body.
• Liquid spills near devices can conduct electricity and cause shocks.
• Damaged or exposed live wires are a direct electrocution hazard.
• Keep liquids away from electrical equipment to prevent accidents.
• Inspect and maintain cables to avoid exposure to live wires.

Fire risks in ICT settings often stem from overloaded electrical sockets and overheating equipment. Overloading occurs when too many devices draw power from a single socket or extension lead, exceeding its capacity.

For instance, plugging multiple high-power devices like printers, monitors, and chargers into one socket can cause the wiring to heat up excessively, potentially igniting nearby flammable materials.

Overheating can also happen if equipment is poorly ventilated or faulty, causing internal components to reach unsafe temperatures. This can lead to fires starting inside the device or spreading externally if not detected early enough. To reduce fire hazards, avoid plugging too many devices into one socket. Use power strips with built-in circuit breakers and ensure all equipment has adequate ventilation. Regular maintenance checks can identify overheating issues before they become dangerous.

• Overloading sockets causes excessive current and heat build-up.
• Multiple high-power devices on one socket increase fire risk.
• Poor ventilation leads to equipment overheating.
• Use power strips with circuit breakers to prevent overload.
• Maintain equipment and ensure good airflow to avoid overheating.

Loose or tangled cables on the floor create tripping hazards, which can cause falls and injuries. In busy ICT environments, cables for computers, printers, and other devices often run across walkways or under desks.

For example, a person walking past a desk might catch their foot on an unsecured cable, leading to a fall that could cause bruises, sprains, or worse.

To prevent tripping accidents, organise cables using clips, ties, or cable trays to keep them off the floor and out of walkways. Colour-coded or labelled cables can also help identify and manage them more easily. Regularly inspect work areas to ensure cables remain tidy and secure.

• Loose cables on floors cause people to trip and fall.
• Tripping can result in bruises, sprains, or fractures.
• Organise cables with clips, ties, or trays to keep them secure.
• Keep walkways clear of cables to reduce hazards.
• Regular checks help maintain cable safety.

Heavy ICT equipment such as servers, printers, or monitors can cause injury if they fall or topple over. This risk increases if equipment is stacked unsafely or placed on unstable surfaces.

For example, a large printer placed on a narrow shelf might fall if bumped, potentially injuring someone nearby.

To reduce this risk, ensure heavy equipment is positioned on stable, level surfaces and secured if necessary. Use appropriate stands or racks designed to support the weight. Avoid stacking heavy items precariously and keep equipment away from edges where it might be knocked off.

• Heavy ICT equipment can cause injury if it falls.
• Unstable placement or stacking increases fall risk.
• Place equipment on stable, level surfaces.
• Use stands or racks designed for heavy devices.
• Avoid positioning equipment near edges or in high-traffic areas.

Maintaining physical safety in ICT environments requires awareness of common hazards and proactive prevention. Key measures include:

Keeping liquids away from electrical devices to prevent electrocution.

Avoiding socket overloads and ensuring good ventilation to reduce fire risk. Organising and securing cables to prevent tripping accidents. Positioning heavy equipment safely to avoid falls and injuries. By following these guidelines, users can create a safer workspace, reducing the likelihood of accidents and ensuring compliance with health and safety standards.

• Keep liquids away from electrical equipment.
• Do not overload sockets; use power strips with circuit breakers.
• Secure cables to prevent trips and falls.
• Place heavy equipment on stable surfaces and secure it.
• Regularly inspect equipment and workspace for hazards.
