API RP 756 – Recommended Practice for Process-Related Hazards

Managing the risk for on-site personnel on hazardous Sites

Recognizing the need for workforce protection from plant site hazards, the American Petroleum Institute (API) adopted API RP 756.

API RP 756 outlines recommended practices for managing the risk from explosions, fires and toxic material releases to personnel located in temporary on-site structures.

To gather data, the API performed vapor cloud explosion (VCE) tests to determine the response of tents to the potential explosion hazards that may be present at refineries, petrochemical and chemical operations.

API RP 756 makes the following recommendations:

  • Manage the occupancy of tents in close proximity to process areas.
  • Design, construct, install, modify, and maintain tents intended for occupancy to mitigate hazards that the tent siting could present to occupants in the event of explosion, fire, and toxic material release.
  • Manage the use of tents intended for occupancy as an integral part of the design, construction, maintenance, and operation of a facility.

Dynamic Air Shelters are the only soft-walled structures in the world to have been fully tested and achieved safe performance in blast zones above 0.9 psi. They are considered to be one of the best solutions to comply with API’s recommended guidelines for managing risks on sites with inherent hazards.
