ABSTRACT
Physical hazards are generally perceptible and discernible. Physical hazards, unlike many microbiological, biological and chemical hazards do not require laboratory analysis for their recognition or description. The hazards that can lead to drowning and injury may be natural or artificial. By definition a hazard is a set of circumstances that may lead to injury or death. The term “risk” is used to describe the probability that a given exposure to a hazard will lead to a certain (adverse) health outcome.
