Purpose of Risk Assessment
The purpose of risk assessment is as follows:
- • Identify existing hazards.
- • Determine the extent of danger that exists.
- • Provide for the ranking of hazards.
- • Organize information for decision making.
- • Give guidance for decision making.
- • Allow for prioritizing risks.
- • Help in characterizing risks, the potential safety and health effects of workers exposed to chemical, physical, and environmental hazards.
- • Identify whether a safety or health hazard dose-response is a critical component to be included.
- • The risk assessment is a needed element of the risk management process.
Even when a risk assessment is conducted, it may result in, at best, a guesstimate due to the lack of quantitative data. This is especially true when trying to establish a real risk picture of a carcinogen. This is because a safe level of exposure cannot be determined.
Risk assessments have become an important component in assuring a safe and effective operation. As safety is designed into processes, risk assessment becomes increasingly important. This will allow engineers to make good designs and operational decisions.
