Technical Safety

Technical Safety is a cross-disciplinary field that combines process engineering, HSE, safety engineering, plant design, and international safety regulations (EPA / OSHA / NFPA).

Our offering provides a wide range of studies, specifications, philosophies, and design services that support both new plant projects and the revamping of existing facilities, significantly improving safety during operation, start-up, shutdown, and any emergency scenario. In particular, after modifications to existing plants, it is essential to reassess hazards, risks, impacts, and existing protection and mitigation systems, and then decide on updates, modifications, or corrective actions to ensure safety levels remain acceptable under regulatory criteria.


By its very nature, Technical Safety is involved in all project phases: concept study, feasibility study, basic engineering, FEED (Front-End Engineering Design), and detailed engineering.
