Action Steps

Confirm that all chemical storage areas, high-volume copy rooms, etc. have:

• deck-to-deck partition walls or hard-lid ceilings;
• self-closing doors;
• designated exhaust (no recirculation); and 
• an exhaust rate of 0.5 CFM/SF, with a pressure differential in relation to surrounding spaces of at least 5 Pa (0.02 inches on water gauge), on average or, when doors are closed, 1 Pa (0.004 inches on water gauge), at a minimum.

Confirm that chemical mixing areas have containment drains.

Confirm that all mechanical ventilation systems can accommodate MERV 13 filtration on outdoor and make-up air supply. 

Confirm that all mechanical ventilation systems can accommodate MERV 13 filtration on outdoor and make-up air supply. 

Once programming and space allocations have been determined, confirm that each of the relevant credit requirements is met, as detailed below.

Develop an outline of all the IEQc5 requirements that apply to your project, and confirm that the schematic design accommodates each one. 

Design in containment drains in spaces where mixing of hazardous chemicals occurs, like labs or maintenance areas.

Provide adequate space for storage and containment of hazardous liquids. 

Design in space for additional ductwork that might be needed to provide designated exhaust for all garages, high-volume copy rooms, janitors’ closets, science labs, workshops, art rooms, or any other spaces that may be used for mixing and storage of chemicals or hazardous materials.

Design an adequate space for ten-foot entryway systems at all regularly accessed building entries. Evaluate all other building entrances—such as employee and service doors—for regular use, which may require entryway systems or roll-out mats.
