– chemical hazards: during the time worker is exposed to chemicals. They can cause illness, skin irritation, even breathing problems,
– ergonomic hazards: improper set up of workstation, repetitive movements,
– psychosocial hazards: stress, cardiovascular diseases.
There are factors that influence the risk of injury, ill health, e.g.
– frequency of exposure and time of contact,
– the nature of exposed (skin contact, inhalation),
– severity of effect (diseases of heart and nervous system, dermal irritation, cancer).
