ICYMI: DOLE issues ventilation rules for the workplaces, public transport


With community quarantine gradually eases in the Philippines, establishments or individuals conducting and providing services are now allowed to operate at limited operational capacity.

To ensure the safety of the workers, especially those inside enclosed spaces, the Department of Labor and Employment (DOLE) has issued Department Order 224-21, signed by Labor Secretary Silvestre Bello II on March 3, 2021, which provides guidance for ventilation that should be observed for private establishments as well as public transport.

See below the following Ventilation Guidelines for Workplaces:

Ventilation Guidelines for Workplaces

DOLE Department Order 224-21

Non-Air-Conditioned Spaces:

  • Maximize natural ventilation through the use of doors, windows, and other openings.
  • If natural ventilation is not feasible or inadequate, mechanical ventilation shall be provided.
  • Exhaust fans should be kept continuously open as much as possible.
  • Conduct weekly (or as necessary) cleaning of windows, other openings, and ventilating fans.

Air-Conditioned Spaces:

  • Run the ventilation system/s for at least 30 minutes before and after spaces are occupied.
  • Keep the blinds or shutters of AC units in an upward position to prevent the air from flowing from one person to another.
  • Establish a regular cleaning and maintenance program for mechanical systems.

Local Exhaust Ventilation (LEV):

  • Must conform to the existing local code with its basic components of hoods, ductworks, air-cleaning devices, fans or blowers, and exhaust stack.
  • Must be equipped with a proper air cleaning device to treat, filter, and minimize airborne contaminants being exhausted to the atmosphere
  • Ensure that running hoods of LEVs are properly secured when not being used during a specific operation to avoid disruption


  • Ensure exhaust fans are functional whenever the building is occupied.
  • Close the toilet bowl seat lid before flushing to minimize releasing droplets into the air caused by flushing.
  • Do not use hand blowers or jet dryers as it contributes to the dispersion of potentially contaminated air inside restrooms.
