Definition of Mental Health First Aid

Mental health first aid is the initial help offered to a person who is developing a mental health problem, experiencing a worsening of an existing condition, or going through a mental health crisis, until professional help is received or the crisis resolves. The term also refers to a specific training program, Mental Health First Aid (MHFA), that teaches non-specialists how to recognize warning signs and respond in a supportive, practical way.

Just as physical first aid does not make someone a doctor, mental health first aid does not make someone a counselor or therapist. The aim is to notice when a coworker may be struggling, start a conversation, offer basic support and connect the person with appropriate help, whether that is an employee assistance program, a doctor, a crisis line or emergency services.

Workplaces are taking a closer look at mental health because psychosocial hazards such as high workload, isolation, shift work, traumatic events and job insecurity can affect wellbeing and safety. Stress, fatigue and distraction can also increase the risk of incidents. Training people to respond is one part of a broader approach to psychological health at work.

How Mental Health First Aid Training Works

Origins and Providers

The MHFA program was created in Australia in 2001 by Betty Kitchener and Anthony Jorm and has since been adapted in many countries. In the United States, Mental Health First Aid is run by the National Council for Mental Wellbeing, which brought the program to the US in 2008 and offers versions for adults, youth, workplaces and specific groups. In England, MHFA England offers courses including a two-day course that trains people as workplace Mental Health First Aiders.

The Action Plan

US courses teach a five-step action plan, often remembered by the acronym ALGEE:

  • Assess for risk of suicide or harm: Approach the person, look for signs of crisis and assess safety.
  • Listen nonjudgmentally: Give the person space to talk without criticism or quick fixes.
  • Give reassurance and information: Offer hope, emotional support and practical information.
  • Encourage appropriate professional help: Help the person consider options such as a doctor, counselor or employee assistance program.
  • Encourage self-help and other support strategies: Discuss support from family, friends, peers and healthy coping strategies.

Certification and Scope

US participants who complete the course receive certification from the National Council for Mental Wellbeing that is valid for three years, after which recertification is needed. Courses typically combine self-paced pre-work with instructor-led sessions. Training covers common conditions, warning signs, crisis situations such as suicidal thoughts or panic attacks, and how to respond. It does not qualify anyone to diagnose or treat mental illness.

Regulations, Standards and Good Practices

What the Law Says

In the United States, OSHA has no standard requiring mental health first aid training, and no federal rule requires employers to appoint trained mental health first aiders. In Great Britain, mental health first aid is also not a legal requirement. HSE's first aid guidance says that after a first aid needs assessment, an employer may decide it is useful to have people trained to recognize and support someone experiencing a mental health issue, and lists options including mental health first aiders, manager training, occupational health support and employee assistance programs. Employers do have general duties to assess risks to health, which can include work-related stress.

Related Standards

ISO 45003:2021 gives guidance on managing psychosocial risks within an occupational health and safety management system. In Canada, CSA Z1003 is a voluntary national standard for psychological health and safety in the workplace. Both treat training as one control among many, alongside work design, workload, leadership and support.

Good Practices for Employers

  • Fit it into a wider plan: Trained responders work best when the organization also addresses causes of stress, such as excessive workload, poor job design or a lack of psychological safety.
  • Clarify the role: Make sure trained staff know their limits, how to escalate, and that they are not expected to act as counselors.
  • Know where to refer: Keep contact details for the employee assistance program, local services and crisis lines, such as the 988 Suicide and Crisis Lifeline in the US, easy to find.
  • Protect confidentiality: Set clear expectations about privacy, with exceptions only where someone's safety is at immediate risk.
  • Support the supporters: Responding to someone in crisis can be draining. Offer debriefs and access to support for trained staff.
  • Consider isolated workers: Remote and lone workers may have fewer chances to be noticed when they are struggling. Regular contact helps, and routine check-ins can also create openings for a supportive conversation.

Example of Mental Health First Aid

At a regional trucking company, a dispatcher who completed MHFA training notices that a long-haul driver who is usually upbeat has become short-tempered on calls, mentions not sleeping, and says something like "what's the point anymore" during a check-in. The dispatcher arranges a private call once the driver is safely parked, asks directly how he is doing, and listens without rushing to solutions.

When the dispatcher asks about thoughts of self-harm, the driver says he has had dark thoughts but no plan. The dispatcher shares the number for the employee assistance program and the 988 line, offers to help him book an appointment, and with the driver's agreement, works with the operations manager to adjust his route so he can be home for a few days. The dispatcher follows up the next week and also uses the company's peer support debrief after the conversation.

Frequently Asked Questions: Mental Health First Aid

Is mental health first aid training mandatory?

Not under federal OSHA rules in the US, and not under HSE rules in Great Britain. Some employers choose to offer it as part of their health and safety or wellbeing programs.

Can a mental health first aider diagnose a condition?

No. The role is to notice, listen, support and connect the person to professional help. Diagnosis and treatment are for qualified clinicians.

How long does MHFA certification last?

In the US, certification from the National Council for Mental Wellbeing is valid for three years. Other national providers set their own refresher periods.

What should someone do if a coworker is in immediate danger?

Call emergency services right away and stay with the person if it is safe to do so. Mental health first aid supports, but never replaces, emergency response.
