156.78—Precautionary statements for physical or chemical hazards.
(a) Requirement.
Warning statements on the flammability or explosive characteristics of the pesticide product are required if a product meets the criteria in this section. Warning statements pertaining to other physical/chemical hazards (e.g., oxidizing potential, conductivity, chemical reactions leading to production of toxic substances) may be required on a case-by-case basis.
(b) Pressurized products.
The table below sets out the required flammability label statements for pressurized products.
| Flash point/flame extension of product | Required labeling statement |
|---|---|
| —Flash point at or below 20 °F | Extremely flammable. Contents under pressure. Keep away from fire, sparks, and heated surfaces. Do not puncture or incinerate container. Exposure to temperatures above 130 °F may cause bursting. |
| OR | |
| —Flashback at any valve opening | |
| —Flash point >20 °F to 80 °F | Flammable. Contents under pressure. Keep away from heat, sparks and open flame. Do not puncture or incinerate container. Exposure to temperatures above 130 °F may cause bursting. |
| OR | |
| —Flame extension more than 18 in. long at a distance of 6 in from the flame | |
| All other pressurized products | Contents under pressure. Do not use or store near heat or open flame. Do not puncture or incinerate container. Exposure to temperatures above 130 °F may cause bursting. |
(c) Non-pressurized products.
The table below sets out the required flammability label statements for non-pressurized products.
| Flash point | Required labeling statement |
|---|---|
| At or below 20 °F | Extremely flammable. Keep away from fire, sparks and heated surfaces. |
| Greater than 20 °F to 80 °F | Flammable. Keep away from heat and open flame. |
| Greater than 80 °F to 150 °F | Combustible. Do not use or store near heat or open flame. |
(d) Total release fogger products.
(1)
A total release fogger is defined as a pesticide product in a pressurized container designed to automatically release the total contents in one operation, for the purpose of creating a permeating fog within a confined space to deliver the pesticide throughout the space.
(2)
If a pesticide product is a total release fogger containing a propellant with a flash point at or below 20 °F, then the following special instructions must be added to the “Physical and Chemical Hazards” warning statement, in addition to any flammability statement required by paragraph (b) of this section:
This product contains a highly flammable ingredient. It may cause a fire or explosion if not used properly. Follow the Directions for Use on this label very carefully.
(3)
A graphic symbol depicting fire, such as illustrated in this paragraph, or an equivalent symbol, must be displayed along with the required language adjoining the “Physical and Chemical Hazards” warning statement. The graphic symbol must be no smaller than twice the size of the first character of the human hazard signal word.
