STANDARDS FOR SAFETY What is an accident? Def: An unplanned event caused by unsafe acts and unsafe conditions. 80% of accidents are caused by unsafe acts! 20% of accidents are caused by unsafe conditions!

STANDARDS FOR SAFETY What are some factors that may cause an accident and possibly injury?  A. Background of the person.  1. Home conditions  2. Personal habits  3. Inexperience  B. Defects of the person.  1. Lack of knowledge or skill (not ready) 20%  2. Improper attitude (not willing) 70%  3. Physical deficiency (not able) 5%  C. Unsafe acts or unsafe conditions.

STANDARDS FOR SAFETY What are some electrical unsafe acts and unsafe conditions that may cause injury, death, or fire? A. Using appliances, tools, and equipment that are improperly grounded B. Failure to use Ground Fault Circuit Interrupters (GFCI) in damp locations. C. Using improper size and type electrical conductors. D. Using electric motors that are too small or lack the proper starting characteristics for the load. E. Improper circuit protection or over fusing.

STANDARDS FOR SAFETY  F. Failure to provide the proper grounding for the system.  G. Failure to use the proper size and type Service Entrance Cable.  H. Failure to use the proper electrical devices.  I. Failure to properly secure or anchor electrical conductors and devices.  J. Overloading circuits.  K. Improper wiring methods and procedures.  L. Inadequate knowledge of electricity and electrical Wiring. 

STANDARDS FOR SAFETY Personal Protective Equipment (PPE) 1. Hard hat 2. Steel-toed shoes a. Rubber heels and toes without nails help insulate against shock 3. Safety glasses 4. Clothes should fit well - Snug 5. No jewelry - metal rings or watchbands 6. Tools should be used that offer you the most protection possible.

STANDARDS FOR SAFETY Safety devices are available to be used in electrical circuits to provide protection for individuals and wiring. 1. Ground Fault Circuit Interrupters (GFCI) 2. Portable GFCls 3. A Circuit Breaker 4. A Fuse

STANDARDS FOR SAFETY  Overload is a condition when too much current flows through the wires, an appliance, a meter, a transformer, or other load being served"  A short circuit is a condition where too much current flows through the wires because the wires of the circuit are touching one another.  A Ground Fault is a condition where the hot wires come into contact with a grounded metal conduit, water pipe, gas pipe, or any other grounded conductive object or surface.

STANDARDS FOR SAFETY OTHER SAFETY CONSIDERATIONS: o A clear work area o Ladders o Wet locations o Common Sense 1. Turn off main service entrance 2. Remove fuse 3. Turn circuit breaker off 4. Test circuit o Animals o Power Line Safety
