Mental ill health and first aid - Advice by HSE:
"Following your employers' first aid needs assessment; you might decide that it will be beneficial to have personnel trained to identify and understand symptoms and able to support someone who might be experiencing a mental health issue.

You should consider ways to manage mental ill health in your workplace which are appropriate for your business, such as providing information or training for managers and employees, employing occupational health professionals, appointing mental health trained first aiders and implementing employee support programmes.

First aid training courses covering mental health, teach delegates how to recognise warning signs of mental ill health and help them to develop the skills and confidence to approach and support someone, while keeping themselves safe."
