Participant informs TPA they are suicidal, can TPA inform the employer?

[Guest El Guapo]

Among other things, our company serves as TPA and processes HRA claims for one of our clients. Today, a participant indicated to one of our reps that he/she is suicidal (not related to her claim). For purposes of the HRA administration, we are a business associate authorized to access PHI for purposes of claims admin.

For the safety of the participant, can we tell their employer that the participant indicated they are suicidal? If not, any advice on how to handle.
