What is SAFETY? SAFETY – is the
condition of being protected from or unlikely to cause danger, risk or injury.
William W.Lowrance – A thing is safe if its risks are judged to be acceptable.
Safety
FREEDOM FROM DANGER OR HARM
Nothing is Free of
DANGER
BUT - We can almost always make something SAFER
Concepts of Safety Engineering
Interdisciplinary ought to be applied early in system development.
Safety should be considered a long-term investment.
Control monetary and physical loses .
Electrical Safety Standards
“Qualified Person” – OSHA 1910.399
The most qualified person to conduct electrical equipment is…
One who has received training and has demonstrated skills in the construct and operation of electrical equipment and hazards involved.
1910.334 Use of Equipment
Covers things like:
Portable equipment
Plugs and cords
Reclosing circuits
Inspection of equipment
Prevention of disease/injury
Promotion of good health and
safety
Improvement of safety and
health
HEALTHY, SAFE, COMFORTABLE PRODUCTIVITY
“Why we need safety??”
Electrician safety rules . Maintain all tools .
Report selective tools .
Tag out defective equipment.
Clean up work area .
Operate equipment according to manufacturers directions.
Proper footwear is mandatory.
-CAUSES…-
Electric failure typically due to :
Improper use.
Inadequate training.
Lack of experience.
Improper (lack of) use of manuals.
Device failure.
-Electric Hazards-
Electric hazards may results in :
Electric shocks.
Thermal burn.
Arc flash effects
Electrical Injuries
Electric Shock Received when current passes through the body
Severity of the shock depends on:
Path of current through the body
Amount of current flowing through the body
Length of time the body is in the circuit
LOW VOLTAGE DOES NOT MEAN LOW HAZARD!!!!!!!
How To Prevent Electric Failure?
The engineers should know the condition of work and workplace.
Take active part in keeping ourselves safe and healthy.
Implementing safe procedures.
