International Safety Systems

What International Safety Systems does

International Safety Systems (ISS), a privately held industrial hygiene and safety consulting firm headquartered in Bellaire (Houston), Texas, delivers on-site EHS services to enterprise clients — primarily in pharmaceuticals, oil and gas, specialty chemicals, healthcare, and aerospace — through 9 country offices and a deployed workforce of 50+ Board-Certified IH and PSM professionals. The company was founded in 2010 and is led by Maharshi Mehta (CIH, CSP, Master's in Occupational Safety from the University of Cincinnati); an earlier firmographic reference to a 1994 founding date is contradicted by the company's own history section and is treated as the secondary, less precise datum.

The service portfolio spans Industrial Hygiene (qualitative and quantitative exposure assessments, engineering controls validation, PPE assessment), Process Safety (HAZOP studies, dust explosion analysis, dispersion modeling), EHS Audits (PSCI supply chain audits, due diligence, compliance audits), Occupational Safety, Ergonomics, Environmental Services, and a recent expansion into Machine Safety (CMSE-certified), Biosafety (CBSP-certified), USP 797/800 Healthcare, SDS Authoring, Asbestos Management, Respirator and Hearing Quantitative Fit Testing, and Flow Testing/LEV Validation. Differentiated tooling includes the ISS-developed pharma-specific exposure assessment methodology, an ergonomics risk assessment framework, COSHH risk assessment software built for a multinational oil and gas client, and the Safety Smart Sheets visual hazard-communication system. ISS is an OHTA-approved training provider and PSCI Knowledge Partner and approved auditor, conducting OHTA training programs and PSCI/EHS supply chain audits globally.

ISS operates a pure professional-services, project-based, quote-driven revenue model with enterprise consulting engagements (no transactional, self-serve, or productized SaaS layer). Demand generation relies on enterprise field sales, conference presence (AIHA Connect, IOHA Dublin, Japan Conference, NSC Ireland), PSCI and OHTA ecosystem participation, an extensive country-specific regulatory resource library, and 200+ delivered training programs and webinars. Direct named customer signals include Merck (with multi-region industrial hygiene leadership engagements and customized training delivery). The customer base spans 500+ workplaces across 35+ countries, with 300+ pharmaceutical sites supported globally and operations anchored in the United States, Ireland, the UK, Germany, France, India, Singapore, China, and Japan.
