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.
