TSCA pre-reform Mandatory duty on EPA to evaluate existing chemicals with clear and enforceable deadlines: No duty to review, no deadlines for action Chemicals assessed against a risk-based safety standard: Risk-benefit balancing standard Unreasonable risks identified in the risk evaluation must be eliminated
TSCA specifically targets "the manufacture, importation, storage, use, disposal, and degradation of chemicals in commercial use." [8] The EPA allows the following to be done: "1. Pre-manufacture testing of chemicals to determine health or environmental risk 2. Review of chemicals for significant risk prior to the start of commercial production 3.
Layers of protection analysis (LOPA) is a technique for evaluating the hazards, risks and layers of protection associated with a system, such as a chemical process plant. . In terms of complexity and rigour LOPA lies between qualitative techniques such as hazard and operability studies (HAZOP) and quantitative techniques such as fault trees and event trees.
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 ...
'Exposure assessment' and 'exposure analysis' are often used as synonyms in many practical contexts. Risk is a function of exposure and hazard. For example, even for an extremely toxic (high hazard) substance, the risk of an adverse outcome is unlikely if exposures are near zero. Conversely, a moderately toxic substance may present substantial ...

The regulation of chemicals is the legislative intent of a variety of national laws or international initiatives such as agreements, strategies or conventions.These international initiatives define the policy of further regulations to be implemented locally as well as exposure or emission limits.
