Use of Powered Mechanical Equipment (PME)

Air Pollution

Common Problems Relevant Environmental Control
Smoke Air Pollution Control (Smoke) Regulation restricts emission of dark smoke from stationary combustion sources.

Practical Solutions

  • Carry out routine maintenance of plant and equipment
  • Retrofit construction plant with particulate reduction device to reduce dark smoke emission
  • Divert plant exhaust to away from public area

Common Problems Relevant Environmental Control
Fuel Air Pollution Control (Fuel Restriction) Regulation prohibits the use of high sulphur content solid and liquid fuel for commercial and industrial appliances.

Practical Solutions

  • Use ultra low sulphur diesel for all diesel-powered plants and equipment
     

Noise Pollution

Common Problems Relevant Environmental Control
--- Under the Noise Control Ordinance, Cap. 400, use of Powered Mechanical Equipment (PME) and Prescribed Construction Work (PCW) are not allowed from 7pm to 7am on the next day or anytime on public holidays, including Sundays.

Practical Solutions

  • Apply Construction Noise Permit for use of Powered Mechanical Equipment (PME) and carrying out of Prescribed Construction Work (PCW) in restricted hours.
    Restricted hours means the time between 1900 and 0700 hours on normal weekdays and any time on a general holiday, including Sunday.
    PCW include:
    • Erection or dismantling of formwork or scaffolding
    • Loading, unloading or handling of rubble, wooden boards, steel bars, wood or scaffolding material
    • Hammering
  • Use Quality Powered Mechanical Equipment (QPME) type equipment
  • Use noise barrier or enclosure for noisy plants
  • Switch off idling equipment
  • Close all engine doors of equipment
  • Fit muffler or silencer for noisy machines
  • Carry out routine maintenance of plant and equipment
