Risk assessment is performed to quantify the potential detriment and evaluate the effectiveness of proposed remediation measures. Environmental risk deals with the probability of an event causing a potentially undesirable effect. An environmental assessment is an opportunity to tour and observe the workplace to understand more about the setting employees work in and the physical factors at and nearby the worksite that support or hinder employee health and evaluate the physical and organizational work environment for health hazards and risks.
A component dealing specifically with human health is often called an environmental health impact assessment. Human health risk assessment program.
