Indoor chemical and pollutant source control

EQc5 | Possible 1 point


Avoid exposure of building occupants to potentially hazardous chemicals that adversely impact air quality.


Design to minimize pollutant cross-contamination of regularly occupied areas:

  • Employ permanent entryway systems (grills, grates, etc.) to capture dirt, particulates, etc. from entering the building at all high volume entryways.
  • Where chemical use occurs (including housekeeping areas and copying/printing rooms), provide segregated areas with deck to deck partitions with separate outside exhaust at a rate of at least 0.50 cubic feet per minute per square foot, no air re-circulation and maintaining a negative pressure of at least 7 PA (0.03 inches of water gauge).
  • Provide drains plumbed for appropriate disposal of liquid waste in spaces where water and chemical concentrate mixing occurs.
