Text For Citation: 01 Item/Group: 001 Hazard:

29 CFR 1910.119(d)(3)(i)(D): Information pertaining to the equipment in the process did not include relief system design and design basis: At the Wichita facility the employer had not developed nor implemented the relief system design or design basis for the equipment in the Ammonia refrigeration processes. The current provided process safety information was not detail, it only referred to the P&ID, there was no documentation of the relief system design and design basis for OSHA to evaluate to ensure the calculations, the designs are correct with the required codes in accordance with "American National Standard for Equipment, Design and Installation of Ammonia Mechanical Refrigeration Systems" sponsored by IIAR and approved by The American National Standards Institute. An overpressure/overtemperature could lead to the opening of the emergency relief devices and the accidental release of ammonia in the air. However, if the relief devices, the safety relief valves are not accurate, are not working properly when needed, then they could not protect personnel and/or equipment from over-pressure conditions. Employees were exposed to catastrophic release of ammonia which results in asphyxiation, explosion and flash fire leading to death and injurie to persons in and near the facility.
