18 • PESTI IDE REGISTRATION AND THE LABEL
Tank-mixing with another esticide or fertilize , unless rohibited. You may want to combine one pesticide with one or several others or with fertilizers. This type of application saves time and reduces application costs. Unless specifically prohibited by directions on any of the labels, it is permissible to apply pesticides in combination.
Even though the label does not prohibit mixtures, you may experience incompatibility problems with certain combinations of pesticides or pesticides and fertilizers. Check for incompatibil- ity before mixing large volumes.
Never mix a pesticide with another pesticide or fertilizer if the label prohibits such a mixture. Label restrictions may specify general classes of chemicals such as sulfur-containing materials, alkaline chemicals, or oils.
Exce tions to or substitutions for ersonal rotective equi ment (PPE) requirements. State regulations provide for the following exceptions to some pesticide label PPE requirements:
If you are using a closed system according to the DPR Director’s closed system criteria to handle pesticide products with the signal
word Danger or Warning, you may substitute coveralls, chemical resistant gloves, and a chemical resistant apron for personal protective equipment required by the pesticide label.* Properly mixing pesticides packaged in water-soluble packets is considered to be using a closed system.
If you use a closed system to handle pesticide products with the signal word Caution, you may substitute work clothing for the personal protective equipment required by the pesticide label.* Properly mixing pesticides pack- aged in water-soluble packets is considered to be using a closed system.
If you are applying pesticides from an enclosed cab (including the cockpit of an aircraft), you may substitute work clothing for personal protective equipment required by the pesticide product label. If respiratory protection is required, you must wear this while applying pesticides from ground application equipment unless the cab is approved for respiratory protection.**
If the closed system you use operates under positive pressure, you must use protective eyewear. Also, all
personal protective equipment required by the pesticide product label must be immediately available for use in an emergency. ** If you are working in an enclosed cab, other than an aircraft, you must have with you all personal protective equipment required by the pesticide product label. Keep this PPE immediately available and store it in a chemical-resistant container, such as a plastic bag. Wear this label-required personal protective equipment if it is necessary to work outside the cab and contact pesticide treated surfaces. Remove and store this PPE in a plastic bag before reentering the cab.
