Maintaining Indoor Environmental Quality (IEQ) during Construction and Renovation

Maintaining Indoor Environmental Quality (IEQ) during Construction and Renovation

Construction and refurbishment in an office environment, refurbished projects may adversely affect building occupants by releasing particulates, biological contaminants and gases from the air. Careful planning of IEQ and prevention of contact in these activities is critical.


Particulate matter such as dust and fibers may be produced during construction and refurbishment activities.

The main sources of these particulate materials include gypsum board, plaster, concrete, soil, wood, masonry, flooring, roofing and piping systems. Non-toxic dust is irritating and can exacerbate lung diseases such as asthma and chronic obstructive pulmonary disease.


Some materials containing fibers (such as fiberglass composites or insulating materials) can irritate the skin, eyes and respiratory tract of the human body in the air and/or when inhaled. Toxic dust containing asbestos, polychlorinated biphenyls (PCBs) or lead can have serious long-term effects on human health.


For all buildings and refurbishment dust, a plan to minimize exposure should be implemented.

Appropriate containment measures should be taken to minimize the damage of dust to the human body.

For example, wear a dust mask.

N95 mask prevents oil-free particles

CE FFP2 masks prevent oily and oil-free particles.
