2. INTRODUCTION
 INDUSTRIAL HAZARD may be defined as any condition produced by industries
that may cause injury or death to personnel or loss of product or property.
 SAFETY in simple terms means freedom from the occurrence of risk or injury or loss .
 INDUSTRIAL SAFETY refers to the protection of workers from the danger of industrial
accidents .
 HAZARD is a condition that creates a level of threat to life, health, property or
environment.

3. GENERAL HAZARDS IN INDUSTRIES:
 FIRE HAZARDS
 MECHANICAL HAZARDS
 ELECTRICAL HAZARDS
 CHEMICAL HAZARDS
 PHARMACEUTICAL HAZARDS
 RADIATION HAZARDS DUST EXPLOSION

4. MECHANICAL HAZARDS
 Large number of equipment
 Crowded work place conditions
 Frequent interaction between worker and equipment
 Insecurely fixed machines
 Failure of SOP
 Dangerous Parts
 Negligence
 Improper maintenance of equipment
Most common in metal industries and construction sites.
Mechanical hazards are mainly caused by errors of an equipment. The hazard can lead to serious injuries or even
death. These risks can be minimized by ensuring that equipment is on good working condition before using it.
Mechanical Hazards can be occur by:

5. Factors responsible are:
PHYSICAL
Physical capability of worker may not meet the job requirement.
PHYSIOLOGICAL FACTORS:
a) Age
b) Time
c) Experience

7. ELECTRICAL HAZARDS
Electricity is the flow of electrons through a substance which allows transfer of electrical
energy from one position to another.
How Shocks occur?
Current Level Probable Effect on Human body
I mA Slight tingling sensation.
5 mA Slight shock felt; not painful but disturbing.
6-30 mA Painful shock, muscular control is lost.
50-150 mA Extreme pain, respiratory arrest, severe muscular contraction and
death is possible
1000-4300 mA Muscular contraction and nerve damage occur. Death
is most likely.
10,000 mA Cardiac arrest, severe burns and probable death

8. The most frequent causes of electrical injury/death are:
i. Contact with power lines
ii. Equipment not used in manner prescribed
iii. 1mproper use of extension and flexible cords
iv. Electric shocks and burns due to poor indication facilities
v. wiring faults and improperly wired equipment
vi. Sparking at loose connection

9. Safety Measures for electrical hazards
Design a safer system
Implement a safe electrical work program
Observe work practice
Use protective equipment
Use warning labels
Recheck the equipment everyday
Heat producing electrical equipment
Overhead electrical wire should have extra care
Recheck the lines everyday
Proper training to workers

10. PREVENTIVE MEASURES
Proper maintenance of wiring and equipment.
High voltage equipment should be properly enclosed.
Indication of danger sign at every high voltage terminal.
Safe work project
Insulation, guarding , grounding, electrical protective devices.
Worker should avoid working with the equipment in wet clothes and
shoes.
Water supply should be far away from electrical circuits.
