Occupational health focuses on the safety and well-being of workers by addressing potential hazards in the workplace, including ergonomic, physical, chemical, biological, and psychological risks. The objective is to prevent work-related injuries and improve overall health for enhanced productivity. Occupational hazards can lead to various health issues such as fatigue, heart disease, and impact from exposure to radiation.

7. PHYSICAL HAZARDS
• Hazards Related To
 Excessive Heat,
 Radiation,
 Cold
 Vibration
 Pressure
 Noise
 Electricity Defects

8. Chemical hazards
 The adverse effects due to
chemicals depend on duration of
the contacts and nature of the
chemical and individual resistance
power.
 Chemicals enters through the
skin, respiratory or digestive
system

9. Biological hazards
Due to infectious micro
organisms like
bacteria,virus,fungus,insects.

products or agriculture are
prone to get infections.

10. Psychosocial hazards
• Due to excessive work,shift
duty,repapeated business
tours,less pay,job dissatisfaction
• The effects are
fatigue,headache, back ache,high
BP,heart diseases,early aging
symptoms etc.

11. Radiation hazards
• Radiation has become an inseparable
part of the living environment.
• Sources of radiation
 Natural sources –cosmic rays
 Manmade sources- x-rays,radio
isotopes,occupational
exposure,luminous markers,radium
watches,TV etc

12. Types of radiation
• Ionising
radiations:alpha,beta,gamma,x-
rays,neutrons
• Non-ionisngradiations:
ultraviolet,microwaves
