ENVIRONMENT HEALTH AND SAFETY (EHS)

ENVIRONMENT HEALTH AND SAFETY (EHS) The effective anticipation and avoidance, minimization, or compensation/offsets of environmental risks and impacts in hydropower development depend on a number of key aspects:

Emergency situations:

  1. Land sliding
  2. Suffocation
  3. Electrical hazards
  4. Earthquake
  5. Floods
  6. Heavy rainfall
  7. Falling hazards
  8. Equipment related emergencies

Landslide: It may occur due to wind and rainfall which may stall the traffic in the site and needs to be cleared immediately.
Suffocation: It may occur inside the tunnel due to its deep structure. Electrical hazards: these may occur due to miss-handling of equipment’s
Earthquake: The area is prone to earthquakes as it falls in (zone 5) which can interrupt working and can cause damage to the property and life.
Floods: these may arise due to heavy rainfalls.
Falling Hazards: the work involves the working of laborers at height. Therefore there is always a risk of falling.
Equipment-related emergencies: The emergencies may also arise due to the failure of the equipment.

Prevention and precautions at emergency situations:

  1. Land sliding:
    • The protection and safety kit should be used in such areas.
    • Safety kit consists of a reflecting jacket, helmets, and gam boots.
    • Working should be stopped in bad weather conditions.

NOTE: if oxygen content exceeds 21.5%, then fire hazards will increase.

  1. Electrical hazards:
    • Proper guidance should be given to workmen to operate machines.• Main supply should be cut down in the case of electrical mishappening.
    • Regular maintenance should be given to machines.
    • To prevent the whole project from being damaged again, retaining walls are provided at the powerhouse.
    • One should switch off the main supply of power in case of floods.
  2. Heavy rainfall:
    • Machinery should be covered with sheds.
    • Checking of machines should be done before its operation.
  3. Falling hazards:
    • Safety belts should be used along with ropes.
    • Workers should be made aware of it and its possibilities.
  4. Equipment related emergencies:
    • Regular maintenance should be done.
    • The equipment should be used in accordance with their permissible limits.
  5. Electrical fire:
    • Fire extinguishers should be used.
    • Electrical appliances should be handled with care.

Safety equipment’s:
➢ Fire extinguisher
➢ Water
➢ Sand bucket
➢ Helmet
➢ Face shield
➢ Nose mask
➢ Glasses
➢ Gumboots
➢ Hand gloves
➢ Earplugs/ ear muffs
➢ Safety belts

Types of fires:

There are 4 types of fires namely Type A, Type B, Type C, Type D.

  • Type A: When solids such as sand, leaves, etc. catch fire, it is categorized as type A fire. This type of fire can be resolved by using water.
  • Type B: When liquids such as gasoline catch fire, it is categorized as type B fire. This type of fire can be resolved by using a fire extinguisher of type B.
  • Type C: When gases catch fire, it is categorized as type C fire. This type of fire can be resolved by using a fire extinguisher of type C.
  • Type D: When a fire erupts due to electrical faults, it is categorized as a type D fire. This type of fire can be resolved by switching off the main supply.
Types of fire extinguishers:

i. Type A: It is a dry chemical powder fire extinguisher.
ii. Type B: It is a foam fire extinguisher.
iii. Type C: It is a carbon monoxide fire extinguisher.
