HAZOP Consultants for Manufacturing & industrial in North America

An Alberta multi-discipline engineering consultancy listing PHA and HAZOP facilitation within its process-engineering practice, a fit for operators wanting hazard-study facilitation from a firm that also carries the process design work.

A California process-safety and regulatory-compliance engineering firm whose engineers facilitate and scribe HAZOP, What-If and HAZID studies, a fit for US operators managing EPA RMP, OSHA PSM and CalARP programs alongside their process hazard analyses.

A small Virginia-based process-safety specialist that also operates in Qatar through a local sponsor — a fit for refining, chemical, manufacturing and pharmaceutical operators wanting a boutique PHA provider with US and Middle East reach.

A California-based process safety and environmental boutique offering HAZOP/LOPA facilitation with strong US regulatory coverage (EPA RMP, OSHA PSM, CalARP) — a fit for domestic operators needing PHA delivered inside a compliance program.

A Sarnia (Ontario) process-safety, reliability and risk consultancy offering PHA facilitation — HAZID, HAZOP and What-If — alongside LOPA, SIL determination and verification, alarm-management and RAM studies, and IEC 61511 life-cycle support.

A Canadian health, safety and process-safety consultancy offering HAZOP/PHA facilitation — HAZOP, LOPA, What-If and FMEA — alongside PSM program development to CSA and OSHA requirements, working across Canada and the United States.

A plant-engineering firm that runs HAZOP studies with its own in-house moderators — a fit for operators who want the facilitator and the plant designer under one roof, drawing on the firm's detailed knowledge of the plant's own parameters.

A process safety specialist that both leads PHA studies and joins them as a subject-matter participant — a fit for pharmaceutical, chemical, food and metals operators who want an experienced facilitator for a HAZOP, What-If or FMEA, a revalidation of an existing study, or dust- and reactive-hazard expertise brought into the review team.

Ontario engineering consultancy that facilitates Process Hazard Analyses — HAZOP and What-If — using PHA-Pro, a fit for Canadian and international operators implementing PSM, EPA RMP, Seveso/COMAH or IEC 61511 risk programs.

A large environmental and engineering consultancy whose process-safety team has facilitated hundreds of PHAs — HAZOP, LOPA, FMEA and What-If — with remote or co-located facilitation, scribing, revalidation and QA/QC review, a fit for US and international operators wanting facilitation backed by a full PSM/RMP compliance practice.

A US EHS-compliance consultancy whose dedicated PHA team facilitates full-facility HAZOPs, PHA revalidations and project-specific hazard reviews — a fit for manufacturers wanting facilitation bundled with wider OSHA and EPA compliance support.

Mexican reliability- and process-risk engineering consultancy running HAZOP, HAZID and What-If studies in Spanish with PHA-Pro deliverables, within a wider practice spanning FMEA, explosion-risk assessment and risk-based inspection — the directory's first Mexican firm and a local-language option for operators across Mexico.

The explosion- and dust-hazard specialist and developer of the FLACS CFD software — its HAZOP teams pair facilitation with deep consequence modelling, strong when the study touches gas or dust explosion risk or energy-transition fuels like hydrogen, LNG, ammonia and CCUS.

Combines HAZOP facilitation with in-house, ISO/IEC 17025-accredited dust flammability and chemical reaction hazard (DSC/ARC) testing labs — useful when a study raises reactive- or explosion-hazard questions the team can't answer from the P&ID.

The global giant: multinationals standardizing HAZOP delivery across dozens of sites in different countries usually end up talking to DEKRA.
