Site-Based Participation

What is Site-Based Participation?

Site-based participation continues VPP's traditional acceptance of applications from fixed worksites and some long-term construction sites.

OSHA welcomes site-based VPP participation and accepts VPP applications from the owners and site officials who control site operations and have ultimate responsibility for assuring safe and healthful working conditions of:

  • Private-sector fixed worksites in general industry and the maritime industry
  • Construction worksites/projects that will have been in operation for at least 12 months at projected time of approval and that expect to continue in operation for at least an additional 12 months
  • Federal-sector fixed worksites
  • Resident contractors at participating VPP sites for the contractors' operations at those VPP sites
  • Resident contractors at non-participating sites for the contractors' operations at those sites, so long as the resident contractors are part of a larger organization approved to participate under the corporate option
Site-Based Participation under the Process Safety Management Standard

To help ensure safe and healthful workplaces, OSHA has issued the Process Safety Management of Highly Hazardous Chemicals standard (29 CFR 1910.119), which contains requirements for the management of hazards associated with processes using highly hazardous chemicals. Process safety management (PSM) is addressed in specific standards for the general and construction industries. OSHA's standard emphasizes the management of hazards associated with highly hazardous chemicals and establishes a comprehensive management program that integrates technologies, procedures, and management practices.

PSM Application Supplement A is a series of questions designed to establish a basic understanding of a VPP applicant's PSM policies and procedures. Applicants covered by the PSM Standard must submit responses to the PSM Application Supplement A along with their VPP application. Participants covered by the Process Safety Management Standard (PSM) will also be required to respond to applicable questions from the annual VPP PSM questionnaire.
