Project Synopsis

Perform process safety and risk management Process Hazards Analysis (PHA) meetings to mitigate the possibility of accidents or releases.

Project Summary


Typical Project Description

On numerous occasions Process Engineering Associates, LLC (PROCESS) has provided engineers experienced in process safety and risk management who have been part of PHA teams for the clients.  The teams performed PHAs of petroleum refining, petrochemical, NGL, and chemical processes to help the clients satisfy the PHA requirements as stated in paragraph (e) of OSHA’s process safety management (PSM) regulation, 29 CFR 1910.119, and part 68.67 of EPA’s risk management program (RMP) regulation, 40 CFR 68.  The objective of the PHAs was to discover potential accidents (i.e., toxic/flammable material releases, explosions, fires) that could directly impact employees, the public, and/or the environment.  PROCESS documented the PHAs to reasonably fulfill all pertinent regulatory requirements.
