Staff members at all levels have the authority and responsibility to improve safety and security procedures wherever these are inadequate. In order to ensure that the security guidelines are successful there must be clear delimitation of responsibility at every level of the organization. All staff should comply with the MHD policy and Code of Conduct and should not behave in any way that could present a risk to themselves, others or the organization. Failure to follow security guidelines and procedures may be treated as a disciplinary matter. Irrespective of the organization’s judgement of risks in a particular situation, any staff member may decline to work in an insecure area, and may withdraw, having first informed their manager. If the risks are constant, continuation of employment will be reviewed, in line with organizational procedure.
