Safety Standards & Maintenance Procedures Flashcards

What is the purpose of Lockout/Tagout (LOTO) procedures?

Answer: To prevent accidental energization during maintenance

Lockout/Tagout (LOTO) procedures are critical safety protocols designed to prevent accidental energization or startup of machinery and equipment during maintenance or servicing. By physically locking and tagging energy-isolating devices, LOTO ensures that hazardous energy sources are controlled. This protects workers from unexpected release of energy, which could cause serious injury or death.

Which of the following PPE is commonly used when working on live circuits?

Answer: Non-conductive gloves and face shield

When working on live circuits, non-conductive gloves and a face shield are essential Personal Protective Equipment (PPE). Non-conductive gloves provide insulation against electrical current, preventing shock. A face shield protects the eyes and face from potential arc flashes, sparks, or molten metal that can occur during electrical faults.

Why is a maintenance log important?

Answer: To ensure accountability and schedule preventive maintenance

A maintenance log is vital for tracking the history of equipment, including repairs, inspections, and service dates. It ensures accountability by documenting who performed what tasks and when, and provides valuable data for scheduling preventive maintenance. This proactive approach helps extend equipment lifespan, reduce unexpected breakdowns, and optimize operational efficiency.

What should be done before performing maintenance on any industrial equipment?

Answer: Disconnect and verify power is off

Before performing any maintenance on industrial equipment, it is paramount to disconnect and verify that all power sources are off. This critical safety step, often part of Lockout/Tagout procedures, prevents accidental energization of the equipment. Ensuring power is off protects maintenance personnel from severe injury or death due to unexpected machine startup or electrical shock.

What is the function of grounding in electrical safety?

Answer: To reduce the risk of electric shock

Grounding is a fundamental electrical safety measure that provides a safe path for fault currents to flow directly to the earth. In the event of an electrical fault, such as a short circuit, grounding quickly dissipates excess current, preventing dangerous voltage buildup on equipment enclosures. This significantly reduces the risk of electric shock to personnel and minimizes damage to electrical systems.
