Working Principle (Cont’d)

lower rates of formulation flow and this can result in surfaces rapidly becoming

coated with the formulation and help to feed a fire if ignition takes place as

described above. Refer to the MAINTENANCE section for cleaning instructions .

7. IMPROPER USE. Never place the discharge end of the machine too close to a

wall or other obstruction. The engine is maintained at the proper operating

temperature by cooling air aspirated (pumped) by hot gases flowing out of the

discharge (exhaust) end of the engine. If this cooling air flow is prevented, the

machine will overheat and it will cause permanent damage which could result in

an explosion or fire. Maintain at least 24 inches (61 CM) clearance between the

engine discharge (exhaust) and external objects.

8. MACHINE DAMAGE. Never operate a machine after it has been damaged. A

damaged machine can be a fire hazard.

9. WIND. Fogging during windy conditions is not usually practical because the

formulation will drift out of the intended area. However, under no circumstances

should fogging INTO the wind be attempted. Should the machine stop running for

any reason, and a wind gust force vaporized formulation back against the hot

combustion chamber, it could ignite and flash back causing momentary flaming

from the discharge (exhaust) end of the machine.

10. CHILDREN. Many fogging operations are performed in residential areas

commonly at dusk. This presents the operator with the problem of children who

are attracted to the fog. Children have been observed running into and riding

bicycles through the fog. Once in the fog, they cannot see or be seen. In some

reported instances, a child has been injured by running into an object obscured

by the fog. Also there is a possibility of fire should the machine briefly flame or

become ignited from an external source. Still another possible hazard lies in the

toxic effect of the formulation, the severity of which depends upon the chemical

used, fog density, and the length of time of direct exposure.

IT IS THE OPERATOR'S RESPONSIBILITY TO DISCOURAGE ANYONE

FROM PLAYING IN THE FOG.
