Q & A

What is electrical safety and why is it critical in mining operations?

Electrical safety refers to the measures taken to prevent electrical accidents, such as shocks, fires, or injuries, that can arise from the use of electrical equipment and installations. It is critical in mining operations due to the high risks involved, including serious injuries, fatalities, and fire hazards that could lead to significant asset loss.

What are the main causes of electrical-related fatalities or injuries in the workplace?

The primary causes of electrical fatalities or injuries are direct human contact with dangerous electrical currents, improper handling or use of electrical equipment, and failure to follow safety protocols or procedures.

Can you provide examples of electrical accidents that can occur at the workplace?

Examples of electrical accidents include workers being electrocuted while washing electrical equipment, such as a portable vacuum pump, or when changing welding rods while the machine is still running. Another example is a fire caused by overloading a power outlet.

What measures should be taken to prevent electrical accidents in the workplace?

To prevent electrical accidents, workers must have competency in electrical work and be authorized by the relevant authorities. It is essential to follow standard operating procedures, ensure all equipment meets safety standards, and regularly inspect electrical equipment. Proper grounding, use of circuit breakers, and maintaining clear diagrams for electrical installations are also important.

Why is it important for electrical work to follow specific safety standards?

Following specific safety standards helps prevent electrical accidents by ensuring that all equipment, installations, and procedures are designed and maintained to reduce the risk of electrical shocks, fires, or malfunctions. It ensures that the workplace remains safe for employees and protects the company's assets.

What are the safety devices and installations that should be used in electrical systems?

Electrical systems should include safety devices such as grounding or earthing systems, circuit breakers (MCBs) to protect against overloads, and fuses to prevent short circuits. Regular inspections and labeling of electrical equipment and installations are also essential.

How can workers ensure electrical systems are safe before performing repairs?

Before performing repairs, workers must ensure that the electrical system is properly isolated by applying lockout and tagout procedures. This prevents accidental power supply while maintenance is being carried out.

What should be done to avoid accidents when digging near electrical cables?

Before performing any digging work near electrical cables, workers should obtain a work permit for excavation and ensure that all underground cables are clearly marked. This helps prevent accidental damage to cables and potential electrical accidents.

What personal protective equipment (PPE) is necessary when working with electrical systems?

When working with electrical systems, workers should wear appropriate PPE, such as helmets, gloves, insulated boots, and protective eyewear. These items help reduce the risk of injury from electrical shocks or accidents.

How can electrical accidents be prevented in areas with fire hazards?

In areas with fire hazards, workers must implement fire prevention measures by ensuring proper insulation of electrical systems and using equipment that is compliant with fire safety standards. Additionally, isolating energy sources through lockout/tagout procedures is essential to reduce the risk of electrical fires.
