GMP Training Program Module 21 Electrical Safety
Electrical Safety Topics • Introduction • Electrical Hazards • OSHA and Electricity • Protecting Against Electrical Hazards • Workplace Practices to Protect You 05/2014
Introduction • Because electricity is such a familiar part of our daily lives we tend to overlook the hazards electricity poses and fail to treat it with the respect it deserves. • However, electricity is a serious workplace hazard 05/2014
Introduction • In 2011, 69 workers died from electrocutions at work • This amounted to 9% of all on the job fatalities that year • Most of these fatalities could have been easily avoided • Why Grounding is important 05/2014
Electrical Hazards • Electric shock • Electrocution • Burns • Fire • Explosions 05/2014
OSHA and Electricity • OSHA electrical standards focus on the design and USE of electrical equipment and systems • OSHA requires that items such as lighting, equipment, motors, machines and appliance switches and connections be constructed and installed in a way that minimizes workplace electrical dangers 05/2014
Protection Against Electrical Hazards • Most electrical accidents result from one of the following three factors: – Unsafe equipment or installation – Unsafe environment, or – Unsafe work practices 05/2014
Protection Against Electrical Hazards • Some ways to prevent these accidents include: – Use of insulation – Guarding – Grounding – Electrical protective devises – Safe work practices 05/2014
What Protection does insulation provide? • Insulators such as Glass, Mica, Rubber, or Plastic used to coat metals help stop or reduce the flow of electrical current • This helps prevent shock, fires, and short circuits 05/2014
How does “guarding” provide protection? • Guarding involves locating or enclosing electric equipment to make sure people don’t accidentally come into contact with its live parts • Conspicuous signs with words like “Danger”, “Warning” or “Caution” alert people to the hazards at hand 05/2014
What is grounding? • Grounding is an electrical system meant to create a lowresistance path that connects to the earth • This prevents the buildup of voltages that could cause an electrical accident 05/2014
Why is grounding important? • Grounding is normally a secondary protective measure to protecting against electric shock • It can substantially reduce the risk, especially when used in combination with other safety measures 05/2014
Work Practices to Protection you • De-energize electric equipment before inspection or repair • Keep electric tools properly maintained • Use appropriate insulating protective equipment such as rubber insulated gloves when necessary 05/2014
What is De-energized? • A break in an electric tool’s insulation cause its metal parts to become “hot” or “energized” • Touching these energized parts can result in an electrical shock, burn or electrocution 05/2014
Energized Tool Production • The best way to protect yourself is to be sure all equipment is grounded correctly • Using cords and plug equipment with a three prong plug is the most common way to ground equipment 05/2014
Don’t ever “turn off” safety! Stay alert and chances are you won’t get hurt! 05/2014
