Another definition of risk is "the probable frequency and probable magnitude of future losses". This definition also focuses on the probability of future loss whereby the degree of vulnerability to hazard represents the level of risk on a particular population or environment. The threats posed by a hazard are:
In hazard identification, sources of data on the risks associated with prospective hazards are identified. For instance, if a site is known to be contaminated with a variety of industrial pollutants , hazard identification will determine which of these chemicals could result in adverse human health effects, and what effects they could cause.
Chemical hazards are usually classified separately from biological hazards (biohazards). Chemical hazards are classified into groups that include asphyxiants, corrosives, irritants, sensitizers, carcinogens, mutagens, teratogens, reactants, and flammables. [1] In the workplace, exposure to chemical hazards is a type of occupational hazard.
A physical hazard is an agent, factor or circumstance that can cause harm with contact. They can be classified as type of occupational hazard or environmental hazard. Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards. [1] Engineering controls are often used to mitigate physical ...
An occupational hazard is a hazard experienced in the workplace. This encompasses many types of hazards, including chemical hazards , biological hazards (biohazards), psychosocial hazards , and physical hazards .
If present, the asterisk signifies a chronic health hazard, meaning that long-term exposure to the material could cause a health problem such as emphysema or kidney damage. According to ACA, the numeric hazard assessment procedure differs from that used by NFPA. [6] [8] [10] 4.
When used as part of an aviation hazard analysis, a "Likelihood" is a specific probability. It is the joint probability of a hazard occurring, that hazard causing or contributing to an aircraft accident or incident, and the resulting degree of loss or harm falling within one of the defined severity categories.
1.2 Explosives with a severe projection hazard. 1.3 Explosives with a fire, blast or projection hazard but not a mass explosion hazard. 1.4 Minor fire or projection hazard (includes ammunition and most consumer fireworks). 1.5 An insensitive substance with a mass explosion hazard (explosion similar to 1.1) 1.6 Extremely insensitive articles.
