Plumbing and mechanical works refer to the installation, repair, and maintenance of systems used for water supply, heating, ventilation, air-conditioning, and waste removal in buildings. These systems include pipes, valves, pumps, boilers, heat exchangers, ducts, and vents. The goal of plumbing and mechanical works is to ensure safe and efficient operation of these systems for the occupants of the building.

Content
Operations
  • Installation of new plumbing and mechanical systems in new construction or renovation projects
  • Repair and maintenance of existing systems
  • Testing and commissioning of new and existing systems
  • Diagnosis and resolution of system malfunctions
  • Replacement of worn or damaged components
  • Upgrades to improve system efficiency and performance
  • Preparation of system drawings, schematics, and specifications
  • Compliance with building codes and safety regulations
  • Conducting regular preventive maintenance to minimize breakdowns and prolong system lifespan.
Hazards
  • Physical hazards such as cuts, burns, falls, and electrical shock
  • Chemical hazards from exposure to toxic or hazardous materials such as asbestos, lead, and solvents
  • Biological hazards from exposure to sewage and other potentially infectious materials
  • Fire hazards from the installation and use of heating and hot water systems
  • Noise hazards from the operation of pumps, fans, and other mechanical equipment
  • Confined space hazards from working in tight or enclosed spaces
  • Airborne particulate hazards from dust and debris generated during installation and maintenance activities.
Controls
  1. Physical hazards:
    • Use of protective gloves, goggles, and other personal protective equipment
    • Implementation of safe work practices, such as ladder safety and fall protection
    • Use of electrical safety equipment, such as grounded electrical tools and GFCI outlets
  2. Chemical hazards:
    • Proper storage and labeling of hazardous chemicals
    • Use of personal protective equipment, such as gloves, respiratory protection, and eye protection
    • Implementation of safe handling procedures, such as ventilation and containment measures
  3. Biological hazards:
    • Use of personal protective equipment, such as gloves, gowns, and masks
    • Implementation of safe handling procedures, such as proper disposal of infectious waste
    • Use of disinfectants and sanitizers to prevent the spread of disease
  4. Fire hazards:
    • Proper installation and maintenance of heating and hot water systems
    • Use of fire-resistant materials and fire suppression systems
    • Implementation of fire safety procedures, such as fire drills and evacuation plans
  5. Noise hazards:
    • Use of hearing protection, such as earplugs or earmuffs
    • Implementation of engineering controls, such as soundproofing or isolation of noisy equipment
    • Regular monitoring of noise levels and implementation of hearing conservation programs
  6. Confined space hazards:
    • Implementation of proper ventilation and atmospheric monitoring
    • Use of personal protective equipment, such as respiratory protection and fall protection
    • Implementation of safe entry and exit procedures, such as standby personnel and rescue plans
  7. Airborne particulate hazards:
    • Use of respiratory protection, such as masks or respirators
    • Implementation of engineering controls, such as ventilation and dust suppression systems
    • Implementation of safe work practices, such as proper housekeeping and wet sweeping procedures.
