Health and Safety Plan (HASP)

Task Hazard Analysis

Although some of the previous elements are a part of the overall safety and health program, several others are additional to these elements and are crucial in developing an effective HASP.

For example, the task hazard analysis may be the most critical component of the site HASP and addresses the chemical, physical, and biological hazards associated with each task or operation and the control procedures that protect employees when they perform that task.

Information obtained from the hazard analysis provides the basis for making important decisions regarding the selection of PPE, medical monitoring, exposure monitoring, etc.

Exposure Monitoring

Exposure Monitoring Instruments

It is important to thoroughly address in the HASP how exposure monitoring will be performed as this is necessary for the protection of site employees. Critical information includes:

  • the frequency and types of air monitoring,
  • personnel monitoring,
  • environmental sampling techniques and instrumentation including calibration and maintenance methods, and
  • the interpretation of monitoring results

For example, there should be established criteria for determining when to upgrade or downgrade PPE based on exposure monitoring results.
