How do you prevent MHFA from handling situations that are for qualified individuals such as their GP or EAP?

The MHFA training makes this clear, it should be made clear in the MHFA role specification and procedures and discussed during regular MHFA peer support and MHFA surgery sessions. It is important to ensure that where an Employee Assistance Programme is in place, all MHFAs have details of that scheme available so they are able to instantly share details of the scheme with those who require support. If in doubt due to serious concerns then using 999 or Samaritans is an option.
