Special Instructions -
Fogging a Room With a Second Room
a. When fogging a room with a second interior room (example: bathroom in a hospital patient room),
measure the length, width and height of both rooms, and combine totals to determine nal room size.
b. Position HaloFogger in the smaller interior room with front handle of the device approximately two feet
from doorway, with the nozzle assembly attached to the side of the fogger pointing the nozzle towards the
door opening, on a 45-degree upward angle. (See Figure 1 below.) Keep interior door open so dispensing
path to main room is not blocked.
c. Position the dehumidier, if one is being used, outside the smaller interior room, centered in the doorway,
facing towards the fogger.
d. Use Chemical Indicator Strips to ensure that the aerosolized disinfectant coverage reached around corners
and all surfaces within both rooms. A protocol may require longer fogging times than indicated on the
standard table to ensure that all corners and surfaces are reached properly.
Special Room Prep for Bathrooms:
• Lift toilet lid, leave in “up” position.
• Toilet seat can remain down.
• Remove all towels, gowns and porous items from room. Shower curtains are generally not removed but are
opened so as to allow free circulation of the aerosol into the shower area and around the curtain itself.
