OSHA cites Army Corps of Engineers' Hanover, N.H., cold research lab for inadequate safeguards against ammonia release

Inadequate and incomplete safeguards against ammonia releases at the U.S. Army Corps of Engineers' Hanover, N.H., Cold Regions Research and Engineering Laboratory have resulted in the issuance of four willful Notices of Unsafe and Unhealthful Working Conditions by OSHA.

The Corps was cited for violations of OSHA's Process Safety Management standard, which is designed to prevent or minimize the catastrophic release of large amounts of highly hazardous chemicals -- in this case, 17,000 pounds of anhydrous ammonia used in the refrigeration system for the laboratory's Ice Engineering Facility.

Among other things, the standard requires employers to: compile written safety information and operating procedures for -- and conduct hazard analyses of -- the process, equipment and technology using the chemicals; develop clear operating procedures; train employees; ensure the mechanical integrity of the equipment used in the process; and evaluate compliance with process safety requirements every three years.

"The potential for a release of ammonia is present as long as these and other proper safeguards are not established, followed and maintained," said Rosemarie Ohar, OSHA's area director for New Hampshire. "In this case, management knew for several years that all these requirements were not being met yet did not correct the hazards. Prompt and complete correction is required and must be a priority."

As a federal agency, the Corps must notify OSHA of corrective actions taken and may, within 15 days, schedule a meeting with the OSHA area director to discuss the violation notices, methods of correction, length of abatement periods and interim protective measures for employees.
