Anytime a part of the human body contacts a flow of electricity, it can become part of the circuit. Depending on the amount energy in a given circuit, a person or body appendage(s) can pass part or all of the electricity resulting numbness, burns, strange\/unusual sensory feelings, heart fibrillation, and\/or heart attack.<\/p>\n\n\n\n

Almost all of the electrical equipment we work with is capable of causing electrocution if used improperly.<\/p>\n\n\n\n

Why worry about electricity?<\/p>\n\n\n\n

Approximately 350 workers are killed in the United States each year as a result of electrical incidents.<\/strong> In addition to heart attack and burns these deaths can occur from falls after contact with electricity.<\/p>\n\n\n\n
