Illustration of Exposure Risk Assessment and Management related to anticipation, recognition, evaluation, control, and confirmation. Occupational hygiene or industrial hygiene (IH) is the anticipation, recognition, evaluation, control, and confirmation (ARECC) of protection from risks associated with exposures to hazards in, or arising from, the workplace that may result in injury, illness ...
Exposure assessment is a branch of environmental science and occupational hygiene that focuses on the processes that take place at the interface between the environment containing the contaminant of interest and the organism being considered. These are the final steps in the path to release an environmental contaminant, through transport to its ...
Examples include high altitudes and unventilated, confined spaces. The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or ...
Ingestion only occurs when food or drink has contact with the toxic chemical. This can happen through direct or indirect ingestion. When food or drink is brought into an environment where harmful chemicals are unsealed there is the possibility of those chemical vapors or particles contaminating the food or the drink.
Occupational dust exposure occurs when small particles are generated at the workplace through the disturbance/agitation of rock/mineral, dry grain, timber, fiber, or other material. When these small particles become suspended in the air, they can pose a risk to the health of those who breath in the contaminated air.
Occupational toxicology is the application of toxicology to chemical hazards in the workplace. It focuses on substances and conditions that people may be exposed to in workplaces, including inhalation and dermal exposures , which are most prevalent when discussing occupational toxicology.
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
Occupational hearing loss is the most common occupational illness in the manufacturing sector. [35] Workers in exceptionally high noise environments, such as musicians , [ 36 ] mine workers , [ 37 ] and even those involved with stock car racing , [ 38 ] are at a much higher risk of developing hearing loss, when compared to other workers (e.g ...
