Psychological health and safety, in one paragraph
A psychologically healthy and safe workplace is one that works to prevent harm to workers' mental health, and promotes their psychological wellbeing. It treats stress, burnout, harassment and the weight of difficult work as risks to be identified, assessed and controlled, not as personal failings.
It sits alongside physical safety, not instead of it. Physical safety has decades of training, equipment and procedure behind it. Psychological safety is newer, and most workplaces are still catching up.
Psychosocial hazards
A psychosocial hazard is anything about how work is designed, organised, managed or experienced that can cause psychological harm. Common examples:
- Workload and pace that people cannot sustain, and long or unpredictable hours.
- Low control over how the work is done, and unclear roles or expectations.
- Poor support from supervisors or colleagues.
- Bullying, harassment, incivility and violence at work.
- Exposure to traumatic events, which is part of the job in fire, police, paramedic, health care and military work.
- Change that is badly managed, and job insecurity.
- Isolation, and lone or remote working.
What the standards ask of employers
In Canada, CSA Z1003 is the national standard for psychological health and safety in the workplace, launched in 2013. Internationally, ISO 45003 gives guidance on managing psychosocial risk within an occupational health and safety management system.
Both ask an organisation to work systematically: identify psychosocial hazards, assess them, put controls in place, check whether those controls work, and review and improve. Both are voluntary. Your legal duties depend on your province, state or country.
Psychological health and safety versus psychological safety
The two phrases are often used together. Psychological safety usually means a team climate where people can speak up, ask questions and admit mistakes without fear. Psychological health and safety is broader: the whole system an organisation uses to prevent psychological harm and promote wellbeing. A team with good psychological safety is one of the things a good system produces.
Where training fits
Training is how a workforce learns to recognise psychosocial hazards, and how leaders learn to act on them. It gives people shared language for stress and load, practical skills they can use on shift, and clarity on where to get help.
NUIRA Safety Training runs three practical courses built on CSA Z1003 and ISO 45003: Resonance and Workplace Psychological Health and Safety for workers, one day each, and Leading Psychological Safety for leaders, over three days. Each comes in a CSA Z1003 or an ISO 45003 edition, general or tailored to a frontline service.
