BMS Field Devices & Their Functions — A Practical HVAC Guide A Building Management System (BMS) is an integrated monitoring and control system used to operate HVAC equipment, electrical systems, pumps, lighting, and other building services. Its purpose is to maintain occupant comfort, improve energy efficiency, monitor equipment performance, and generate alarms when operating conditions fall outside defined limits. In a hospital such as AKUH, a properly configured BMS is especially important for monitoring critical areas such as operating theatres, ICUs, isolation rooms, laboratories, and medical support facilities. 1. How BMS field devices work together Field sensors and input devices Temperature, humidity, CO₂, pressure, airflow and equipment status Measured signals DDC controller Reads inputs, executes control logic, compares values with setpoints Control commands Actuators and control devices Valve actuators, damper actuators, VFDs and equipment enable commands HVAC equipm...
HSE Guide: Types of Workplace Incidents and Their Classification Incident classification is a fundamental part of Health, Safety and Environment (HSE) management. It helps organizations measure workplace safety performance, investigate incidents, identify hazards, comply with reporting requirements, and prevent recurrence. In healthcare facilities such as AKUH, as well as construction projects, hotels, industrial plants, and facility management operations, incident classification is especially important because an event may affect employees, contractors, patients, visitors, equipment, critical utilities, or the environment. 1. Understanding the incident classification hierarchy 1. Near Miss No actual harm An unplanned event that did not cause injury, illness, damage, or other loss, but had the potential to do so. Example: A tool falls from a maintenance platform and narrowly misses a technician. 2. FAC — First Aid Case Basic first aid A work-related injury requiring limited first...
