What does pamechanical mean?

PA, which means public area, is managed by the housekeeping department in the hotel, and is mainly responsible for the sanitation management and the maintenance of facilities and equipment in the public area of the hotel.

I don't know, it's not a senior position, but it's a little more technical than other work in the department, such as washing liquid ratio, mirror polishing of marble floor, etc. Someone once worked as a housekeeping manager from PA, but there are too few such examples.
