For Physical Hazards-

Vulnerable groups: Certain people or households are more at risk from environmental hazards because they are:

• Less able to avoid them (e.g. living in a settlement lacking provision for protected water, sanitation and drainage).
• More affected by them (e.g. infants are at much greater risk of death from diarrhoea and acute respiratory infections than older groups).
• Less able to cope with the illness, injury or premature death they cause (e.g. persons who cannot afford treatment from a doctor or medicine).

Prevention: wear proper gear while working, work according to what your physical conditions allows
