What is HOD mentioned in the hotel? Also, HAACP and P&Ps, what are their full names?

It should be HACCP not HAACP.

HACCP is the abbreviation of Hazard Analysis Critical Control Point (English Hazard Analysis Critical Control Point). As a scientific and systematic method, it is applied in the process from primary production to final consumption to ensure food safety by identifying and evaluating specific hazards and their control measures. HACCP is internationally recognized as the most economical method to control diseases caused by food, and has been recognized by the FAO/WHO Codex Alimentarius Commission (CAC).

P&Ps refers to the policies and principles that form part of the Safety and Management System (SMS). Based on the lessons learned from various catastrophic accidents, it was found that the major cause of these accidents was the negligence of managers. P&Ps are considered hazard checklists used to identify any potential risks of managerial negligence leading to accidents.

HOD is not very clear; it may refer to head of department- department head; or it is a software Hadoop on Demand.
