Electricity is an essential element of the workplace. It provides light, heat, motive power and communications, but it is also dangerous. The need to constantly maintain, repair and upgrade electrical equipment means that employees will sometimes be in close vicinity to electricity and therefore exposed to some risk. This interactive online course covers the dangers of an arc flash and the effects of different current flows on the body. It describes the importance of a lockout tagout program and the goal of the NFPA 70E standard.

The following key questions are answered in this module:
What are the factors that affect shock severity? The factors that affect shock severity include: 1. The amount of current. 2. The duration of a shock. 3. The path the current takes through the body.
What is the goal of NFPA 70E standard? The National Fire Protection Association (NFPA) created the 70E standard called the "Standard for Electrical Safety in the Workplace". It is a guide for establishing safe work practices for personnel working with or near electrical equipment. NFPA 70E requires employers to implement an Electrical Safety Program appropriate to the risk associated with various electrical hazards.
What are some guidelines for preventing electric shock? Some guidelines for preventing electric shock include: 1. De-energizing equipment. 2. Using only insulated tools and test instruments. 3. Using appropriate personal protective equipment (PPE).
What are the basics of a lockout tagout program? Lockout tagout (LOTO) refers to a set of procedures that protect workers from the unexpected energization of machinery and equipment or the release of hazardous energy during service or maintenance activities. It involves shutting off energy at control points such as switches and circuit breakers and placing locks and tags on those controls to prevent the system from being re-energized. Before working on de-energized, locked or tagged out equipment, verify the equipment is safe.
What are some of the effects of different current flows on the body? A current of 0.001 amps (1 milliamp) creates a detectable sensation. At 0.01 amps a shock is painful. A current of 0.1- 0.2 amps will lead to ventricular fibrillation and can be lethal. Currents above that will cause internal organ damage in addition to heart problems. Burns can occur on your skin, where electricity enters your body, or within your body as the electricity flows through you.
