Fire suppression equipment must be manned.
Does it mean that operators should be provided? The meaning for "man" is somewhat ambiguous for me.
According to Cambridge dictionary, "man" (verb) means:
To man something such as a machine or vehicle is to be present in order to operate it
According to Merriam-Webster dictionary, it means:
to supply with people (as for service)
Does it mean that personnel should be provided along with the device being provided?
