PRIORITY ISSUE 9.0 TRACKED-IN POLLUTANTS
ASSESSMENT PROTOCOLS (AP) MINIMUM ACTIONS (MA) EXPANDED ACTIONS (EA)
AP 9.1 Inspect Floor Surfaces at
Building Common Entrances
Inspect all building common entrances
for walk-off mats or entry mat systems.
Note accumulation of dirt or moisture
on interior floors near building entrances
that might indicate need for walk-off
mats or entryway floor-cleaning systems.
MA 9.1 Provide Walk-Off Mats
Provide walk-off mats to trap dirt
and moisture at all building common
entrances. The mats need to be long
enough to allow at least five full steps
for people entering the building (a
minimum of 10 feet long). Walk-off
mats should be regularly vacuumed and
cleaned according to manufacturer's
printed instructions. Mats should have
anti-slip backings or other means to
reduce sliding and tripping hazards.
Mats should not be placed over carpeted
areas and should have an impervious,
readily cleanable surface beneath them.
Note:
Mats should be periodically moved and
allowed to dry. Mats in high-traffic areas
and over vinyl flooring should be moved
and allowed to dry frequently during
wet weather conditions (e.g., on a daily
basis).
EA 9.1 Install Permanent Entryway
Systems
Install permanent entryway systems
at all regularly used building common
entrances to capture dirt and moisture,
as described in ASHRAE Standard
189.1-2014, Section 8.3.1.5 or EPA's
IAQ Design Tools for Schools, Entry Mat
Barriers. The entryway system should:
• Provide a scraper surface, an
absorption surface and a finishing
surface, in sequence in the direction
of travel into the building.
• Be as wide as the entry doors.
• Have anti-slip backings or other
locking mechanisms to reduce sliding
and tripping hazards.
• Be designed for regular cleaning to
remove accumulated dirt.
• Not be installed over an existing
walk-off mat or other entryway
system.
