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 ...
The anticipate, recognize, evaluate, control, and confirm (ARECC) decision-making framework began as recognize, evaluate, and control.In 1994 then-president of the American Industrial Hygiene Association (AIHA) Harry Ettinger added the anticipate step to formally convey the duty and opportunity of the worker protection community to proactively apply its growing body of knowledge and experience ...
The final step of an occupational risk assessment is risk characterization. This is where the data gathered is combined to create estimations about safe levels. NIOSH makes Recommended Exposure Limits (REL), [1] while other organizations may create occupational exposure limits (OEL). [3]
The exposure assessment involves evaluating relevant exposure routes (inhalation, ingestion, dermal, and/or injection), amount, duration, and frequency (i.e., dose), as well as whether exposure controls are in place and how protective they are. When data are not available, this will be a qualitative process.
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 ...
Workplace exposure monitoring is the monitoring of substances in a workplace that are chemical or biological hazards. It is performed in the context of workplace exposure assessment and risk assessment .
Risk assessment determines possible mishaps, their likelihood and consequences, and the tolerances for such events. [1] The results of this process may be expressed in a quantitative or qualitative fashion. Risk assessment is an inherent part of a broader risk management strategy to help reduce any potential risk-related consequences. [1] [2]
Example of risk assessment: A NASA model showing areas at high risk from impact for the International Space Station. Risk management is the identification, evaluation, and prioritization of risks, [1] followed by the minimization, monitoring, and control of the impact or probability of those risks occurring. [2]
