    A Complete Guide to Industrial Electrical Safety

    Industrial Electrical Safety Guide

    In this guide we will be examining the dangers of electrical equipment in factories and other industrial environments and discussing recommended methods for managing those risks and protecting the health and safety of employees, contractors and visitors.

    Electrical hazards and safety

    Almost every factory or workplace features electrical equipment of some kind. If poorly maintained such machinery can cause serious accidents. The risks increase the larger and more powerful the equipment, making electrical safety measures even more important.

    To ensure workplace safety all wiring and circuits must be properly and fully inspected on a regular basis: this is perhaps the single most effective way to protect employees from shocks.

    Why is electrical safety important?

    Electricity is dangerous: it can arc across spilled liquid and damp surfaces; it can start fires, igniting flammable materials - even gases and dust - causing serious damage to equipment and buildings. Electric shock can cause burn injuries and interfere with the heartbeat of anyone exposed, with potentially fatal results. The symptoms of electric shock range from headaches, numbness and blurred vision, all the way up to an irregular heartbeat, spasms and seizures. Even relatively minor shocks can cause major injuries – by, for example, causing heavy objects to be dropped or workers to fall from ladders.

    Electrical safety at work: a checklist

    The key principles of electrical safety at work are:

    Although the amount and strength of electrical equipment in use varies according to industry, these principles are fundamental and apply more or less equally to hospitals, factories, offices and warehouses.

    Electrical safety products

    The following safety products are widely used by industrial firms to protect their machine operators and employees from electrocution and related risks.

    COBASwitch-Electrical-Safety-Mat

    Electrical safety mats

    Also known as insulation mats or switchboard matting, electrical safety mats provide some degree of protection from high voltage discharges.They are made from insulated rubber and should be placed near potentially dangerous machinery and live switchboards.

    VDE-toolkit

    Electrical safety toolkits

    Electrical safety toolkits are used by electricians and properly qualified professionals to test and repair electrical equipment. Tools that are insulated and have a VDE approval are ideal for use with electricity as they have been specifically designed to protect against the risk of an electrical shock.

    Portable appliance testing (PAT)

    Portable appliance testing (PAT)

    Portable appliance tester kits are used by electricians and properly trained workers to verify the electrical safety and working order of portable appliances, which are especially prone to wear.

    Insulation testing

    Insulation testing

    Insulation testers are handheld devices used to monitor the electrical flow within cables, motors, switches, generators and similar equipment. The electricity that escapes from insulated cables can feed back, interfering with equipment.

    Voltage indication and testing

    Voltage indication and testing

    Voltage indicators are standard safety equipment for most electricians. These handheld devices provide a quick and reliable indication of live currents in particular circuits.

    Lockout kits

    Lockout kits

    Also known as lock-offs, lockout kits are sets of tools used to cut off electrical currents and ensure the safe isolation of devices that require repair or close checking.

    Earth or ground testing blocks

    Earth or ground testing blocks

    Also known as ground terminal blocks or earth terminals, earth blocks are used to safely ground cables and wires to protect from electrical discharge or magnetic fields. Typically, they are screwed or clamped into place.

    RCD testing

    RCD testing

    Residual current devices (RCDs) automatically swift off electricity in the event of such faults as exposed wires, earthing failures or overheating – and they can save lives. Alternative names include residual circuit breakers (RCCBs) in the UK and ground fault circuit interrupters in the United States.

    Electrical safety signs & posters

    Electrical safety signs & posters

    Electrical safety posters are a convenient way to promote electrical safety and raise awareness amongst employees of good working practices. They must be reliable and accurate. Display them in common areas such as canteens and breakrooms, as well as near hazardous areas such as electrical rooms and substations.

    Safety signs provide immediate visual signals of potential electrical danger and they should be displayed in all potentially hazardous working areas. Their effectiveness will be complemented by staff training.

    Provide up-to-date electrical safety handbooks as reference material for properly trained employees and on-site electricians.
