BEFORE FOGGING (Cont’d)

NOTE

Tables 1 and 2 are provided as a quick reference for determining fogging time.

As a "rule of thumb." when fogging indoors, your metering valve setting should

never exceed 4. If your machine is equipped with fixed orifices instead of a

metering valve, use the #36 orifice fitting as a maximum indoor rate. ALSO, the

operator must maintain at least 2.4 meters (8 feet) of clearance between the

discharge end of the machine and the target being fogged.

Example: (Using English System Units)

STEP 1: Let’s assume that the attic space shown on the previous page has a

base (W) of 26 feet, and a height (H) of 7 feet and a length (L) of 43 feet. The

volume (V) may be determined as follows.

The volume (V) may be determined as follows:

V = 26 x 7 x 43 = 3913 = 3900 cubic feet

Let's also assume that the formulation label specifies a normal usage rate of 1

ounce per 3000 cubic feet (Table 2). Knowing the usage rate from the

formulation label and the volume of space to be fogged, the formulation volume

and fogging time can be calculated as shown below.
