DISCLAIMER: The expert advisor referenced on this page was designed several years ago and although it should function using the latest versions of Windows without problem, there may be instances where it is no longer compatible (i.e., Windows 64-bit).

OSHA conducts inspections of hazardous waste site activities. During these inspections, deficiencies in written Health and Safety Plans (HASP) are commonly found. These deficiencies generally indicate a lack of knowledge and/or understanding of the required content of the HASP. The most consistent deficiency is a lack of site-specificity in the plans.

In the early 1990s, EPA's Environmental Response Team published a DOS-based software package which generated a model HASP. It contained some automatic fill options and simple decision logic, but was limited in its programmed features and in its capacity to generate a site-specific HASP. Based on field evidence, both Agencies became interested in updating the original EPA software. As a result, the original e-HASP Program (Version 1) using Windows-based software was developed and completed in September, 2003. Since then, numerous comments were received to improve the functionality and "user friendliness" of the software.

The updated e-HASP2 (Version 2) Program continues to use Windows-based software and includes decision logic to assist the user in determining the appropriate controls for health and safety hazards on their sites. The integrated chemical database has been improved with more chemicals and updated exposure limits. Some of the other notable upgrades for e-HASP2 include: 1) upgrades to pick-lists, 2) function to add new chemicals that are not in the chemical database, 3) function to export reports to a word processor for editing, 4) new "preview chapter" button, and 5) a newly designed job hazard analysis (JHA) chapter.

e-HASP2 is an electronic and interactive program that is intended to be used by health and safety professionals to provide "model" language that is acceptable to OSHA in preparing a site's HASP. These same professionals can also draw on the chemical database and embedded decision logic to assist them in identifying the hazards associated with site-specific contaminants and in choosing effective site controls for worker protection.

The e-HASP2 software includes fifteen chapters and these are listed below.

  • Organizational Structure
  • Job Hazard Analysis
  • Site Control
  • Training Program
  • Medical Surveillance Requirements
  • Personal Protective Equipment (PPE)
  • Exposure Monitoring
