Remember...“Keep ceiling tiles, carpet, and other porous materials away from the work area and install them after VOC and other construction emissions have dissipated.”
Ceiling tiles, carpets, and other porous materials will adsorb pollutants during renovation and re-emit the pollutants into the occupied space at a later time (e.g. during warmer weather).
In the picture, the kerosene heater and the painting emissions are being adsorbed by the ceiling tiles and wall panels. When the weather turns warm again, occupants may well experience indoor air quality problems as these pollutants are re-emitted into the occupied space.
In addition to not storing porous materials in the construction area, it is a good idea to increase outdoor ventilation for a short time after construction, and again during the first spell of warm weather.
