Psychosocial risks are becoming a major occupational health and safety priority. Organizations are increasingly expected to manage risks involving stress, fatigue, burnout, bullying, harassment, poor communication, workload pressure, and psychological wellbeing.
ISO 45003:2021 provides guidance for managing psychosocial risks within an OH&S management system based on ISO 45001. It supports organizations in preventing work-related injury and ill health while promoting wellbeing at work.
ISO 45003:2021 is an international guidance standard titled Occupational health and safety management — Psychological health and safety at work — Guidelines for managing psychosocial risks.
The standard provides guidance for managing psychosocial risks within an occupational health and safety management system based on ISO 45001. It is applicable to organizations of all sizes and sectors.
ISO 45003 is not intended for certification. Instead, it helps organizations strengthen psychological health and safety by improving how psychosocial risks are identified, assessed, controlled, monitored, and continually improved.
| Area | ISO 45001 | ISO 45003 |
|---|---|---|
| Purpose | OH&S management system requirements | Guidance for managing psychosocial risks |
| Certification | Certifiable standard | Guidance standard only |
| Main Focus | Occupational health and safety management | Psychological health and safety at work |
| Risk Coverage | OH&S hazards and risks | Psychosocial hazards and psychological wellbeing |
| Use in Practice | Used for OH&S system implementation and certification | Used to strengthen psychosocial risk controls within the OH&S system |
Psychosocial hazards are factors in the design, organization, management, and social context of work that may negatively affect psychological health and safety.
These hazards are often less visible than physical hazards, but they can significantly affect worker wellbeing, concentration, behaviour, productivity, incident likelihood, and organizational performance.

Explore ISO ResourcesPsychosocial risk controls should be practical, proportionate, and integrated into existing OH&S processes. Organizations should avoid treating psychological health and safety as a separate activity disconnected from operational risk management.
| Risk Area | Example Controls |
|---|---|
| Workload Pressure | Workload monitoring, manpower planning, overtime control, realistic deadlines. |
| Fatigue | Rest breaks, shift planning, fatigue reporting, work-hour monitoring. |
| Bullying & Harassment | Anti-harassment policy, confidential reporting, investigation process, supervisor training. |
| Poor Communication | Toolbox meetings, consultation sessions, clear role communication, change briefings. |
| Remote Work Isolation | Regular check-ins, ergonomic guidance, communication channels, workload visibility. |
| Low Worker Support | Employee assistance programme, counselling access, wellbeing awareness, escalation pathways. |
ISO 45003 itself is not certifiable. However, auditors assessing ISO 45001 implementation may evaluate whether the organization has considered psychosocial risks as part of its OH&S risk management process.
A common weakness is treating mental health as a standalone HR programme without linking it to OH&S hazard identification, risk assessment, operational control, consultation, and performance evaluation.
Organizations can begin by integrating psychosocial risk management into existing ISO 45001 processes rather than creating a separate system.
| ISO 45001 Process | Psychosocial Risk Integration |
|---|---|
| Context of the Organization | Identify internal and external issues affecting psychological health and safety. |
| Worker Consultation | Include worker feedback on workload, communication, supervision, and wellbeing risks. |
| Hazard Identification | Include psychosocial hazards in hazard registers and risk assessments. |
| Operational Control | Establish controls for workload, fatigue, harassment, communication, and remote working. |
| Performance Evaluation | Monitor trends such as absenteeism, complaints, turnover, incidents, and worker feedback. |
| Improvement | Take corrective actions where psychosocial risk controls are ineffective. |
No. ISO 45003:2021 is a guidance standard. It supports ISO 45001 implementation but is not intended for certification.
ISO 45001 provides OH&S management system requirements, while ISO 45003 provides guidance for managing psychosocial risks within an ISO 45001-based OH&S management system.
Yes. Psychosocial risks can affect worker health, concentration, behaviour, safety performance, and overall organizational effectiveness.
Yes. Organizations should evaluate psychosocial hazards relevant to their activities, work arrangements, workforce needs, and operational conditions.
