It is a two- or four-stroke piston engine where heat energy is developed by burning an air-fuel mixture inside the combustion chamber, producing mechanical energy (reciprocating/rotating forces of expanding gases) to drive a piston, shaft, or propeller.
It is the amount of energy/work required to raise/create/force 33,000 pounds one foot in one minute; equivalent to 746 watts or 746 joules/second.
Includes portable/mobile generating units, standby units, engine-driven generators in power plants (primary electrical source), prime movers for industrial manufacturing processes, and internal combustion engines used in construction/agricultural services and similar applications. It excludes transportation engines such as automobile, aircraft, compressor engines, marine/ship motors.
No. Rule 1182(1) states no internal combustion engine shall be installed and/or operated without a permit issued by the Secretary of Labor and Employment or authorized representative.
It must be filed through the Regional Labor Office concerned, accompanied by the manufacturer’s data sheets, working drawing, foundation with design computation, installation and site location plan and vicinity map—submitted in five (5) copies, signed and sealed by a professional mechanical engineer and signed by the owner.
It is valid during the period covered by the permit unless revoked for justifiable reasons (e.g., unsafe operation).
Any removal and/or change of location must be reported to the Regional Labor Office concerned and it shall be considered as a new installation.
It must be reported to and an application must be filed with the Regional Labor Office concerned.
Chapter 2 of the Philippine Society of Mechanical Engineering (PSME) Code and Rule 1060 of the Occupational Safety and Health Standards are applied as minimum requirements.
Inspections occur during foundation/installation construction, before being placed into service after installation, before service after modification, and periodically at intervals not exceeding 12 months.
Crack on base foundation, noise level, excessive vibration, exhaust gas emission level, heat level, and ventilation system.
Engine room must be at least 3.0 meters high (or as specified by manufacturer); provide adequate spaces for operation/maintenance with at least 1.0 meter clearance around engine to walls/equipment; maintain normal atmospheric conditions via natural/artificial ventilation to avoid toxic gases and excessive heat; and have two independent doors for access.
Gasoline or liquefied petroleum gas fueled engines shall not be installed in rooms/locations containing fired equipment or open flames.
All exhausts must be directed outside to a safe area in accordance with DENR requirements.
Floor slabs/footings must be isolated from the foundation base by at least 25 mm around the perimeter to eliminate transmission of vibration; the opening is filled with watertight insulation.
On-duty personnel for engines requiring regular attendants must be provided with personal protective equipment appropriate for the present hazard.
The installation plan must include the piping installation details, particularly those within 2.13 meters from the floor line.
All steam, water, air, gas, hazardous substances, and oil piping, including components such as pipes, flanges, bolting, gaskets, valves, fittings, and other related components for steam/central heating/industrial plants.
It cannot be connected/installed without plans cleared by the Regional Labor Office, and it cannot be operated until required documents are submitted and a final inspection is conducted, with a safety permit issued upon payment of the inspection fee.
(a) For new installation: hydrostatic test equal to 1.5 times the service operating pressure for minimum 24 hours. (b) For existing repaired/installation: equal to 1.5 times service operating pressure for minimum 4 hours.
