A Hazard is anything with the innate potential to cause harm.
A Risk is the likelihood for harm to occur
-HAZARD + RISK = HARM.

A pool filled with crocodile is a hazard and when you bring man to that same pool, it's a risk which likely going to cause harm to the man.
Classification of hazards
Based on environment they occur
-physical: known as objective hazard. Minimal matter yet capable of affecting the biological mechanism of exposed workers. E.g Radiation, noise, temperature, pressure, vibration, light, electric e.t.c.
-chemical: especially used in industries e.g pesticides, acids, alkali, benzene, asbestos, silica, coal dust e.t.c.
-biological: caused by living organisms e.g viruses, bacteria, fungi, helminths, as well as toxic or allergic reactions to plants, insects, birds, animals including humans.
-mechanical: known as functional hazards arising from accidents like injuries from tools and machines. E.g slips, trips, falls, abrasion e.t.c.
-social: human to human interaction at work. E.g malingering, alcohol, stress, depression,bullying e.t.c they usually affect job satisfaction or well being.
