What is the difference between an SMS and an EHS management system?

An SMS focuses specifically on safety risk management. An EHS management system is broader, integrating environment, health, and safety into a single framework. In practice, the terms are often used interchangeably.

Is an SMS required by OSHA?

OSHA does not mandate a specific SMS framework, but strongly recommends organisations implement one following its recommended practices. Some industries (aviation, nuclear, offshore oil and gas) have regulatory SMS requirements.

GLOSSARY

Safety Management System (SMS): Definition, Components & How AI Enhances It

A safety management system (SMS) is a structured framework for identifying, assessing, controlling, and continuously improving workplace safety risk. It combines safety policy, risk management, assurance, and promotion so safety becomes part of daily operations instead of a standalone compliance activity.

What Is a Safety Management System?

A safety management system (SMS) provides a structured approach to managing safety in an organisation — integrating safety into all business processes and ensuring risks are systematically identified, assessed, and controlled. An SMS is the backbone of any mature workplace safety programme.

The 4 Core Components of an SMS

Safety Policy — establishes management commitment, accountabilities, and the overall safety strategy
Safety Risk Management — hazard identification, risk assessment, and implementation of risk controls
Safety Assurance — ongoing monitoring, internal auditing, and performance measurement to verify effectiveness
Safety Promotion — safety training, communication, and culture-building activities

SMS Standards and Frameworks

ISO 45001:2018 — the international standard for occupational health and safety management systems
OSHA Recommended Practices for Safety and Health Programs
ICAO SMS Framework (aviation-specific)
HSE's Managing for Health and Safety (UK)
