There is now considerable evidence showing that whilst most individuals who are exposed to traumatic events show resilience and do not suffer any longer-term negative psychological effects, it is inevitable that some will suffer temporary distress whilst a smaller proportion will develop formal mental health disorders (including but not limited to PTSD).

It follows that organisations that operate in environments in which the likelihood of exposure to traumatic situations is considerable, who have a duty of care for their staff, should put in place reasonable mitigation measures. This guidance by the UK Psychological Trauma Society (2014) highlights the areas that organisations whose staff are exposed to potentially traumatic situations and/or material should consider addressing in their Health and Safety procedures.
