CALCULATING FOGGING TIME AND
FORMULATION VOLUME USING YOUR
MODEL 2620 BLACKHAWK
FOGGING WITHIN ENCLOSED SPACES:
When intending to fog within enclosed spaces such as buildings, crawl spaces, and spaces
between ceiling and roof, “dry” fog must be used. The enclosed space volume, formulation volume,
and fogging time must be carefully calculated to avoid over-fogging.
Volume formulas for simple shapes usually found in structures are shown below:
V = L x W x H V= L x W x H

BEFORE FOGGING:
1. Determine the volume of the enclosed space to be fogged in cubic feet or cubic meters, as
applicable.
Read the formulation label and determine the normal usage rate of the formulation. This usually
varies from 1 fluid ounce (oz.) per 1000 cubic feet, (approximately 100 milliliters per 100 cubic meters)
to 1 ounce per 3000 cubic feet (approximately 100 milliliters per 300 cubic meters).
2. Determine the Formulation Volume.
3. Determine the fogging time.
NOTE
Tables 1 and 2 are provided as a quick reference for determining fogging time. As a “rule of
thumb”, the operator must maintain at least fifteen (15) feet of clearance between the discharge
end of the machine and the target being fogged.
