Do not store the regulator when saturated with chemicals, as it is unsafe and could also result in
damage to the equipment.
WARNING
Cleanup and decontamination procedures must be followed after each use.
Improper equipment cleanup and disposal of chemicals can result in dangerous chemical
exposure to humans and the environment, as well as equipment damage.
Personal decontamination is required after spraying to minimize unsafe exposure to chemicals
and potential illness.
1. Drain pump
system
If there is excess pesticide left in the system, drain the system:
a) Disconnect power to the pump and relieve system pressure.
b) Find a suitable container in which to drain the unused pesticide.
c) While wearing rubber gloves, eye protection, and all other required
personal protective equipment, allow pesticide to drain into container.

Properly dispose of the remaining chemical and its container per the
chemical manufacturer’s recommendation and according to local

A general procedure is as follows:
a) Add fresh water to the pump system.
b) Reconnect power to the pump.
c) Operate the pump system and discharge all rinse water onto an area
that can accept dilute pesticide application.
