Appendix A to Part 274 - Preventive Safety Measures in Handling of Pesticides

1. Follow the label on each container before using the contents. The manufacturers are required by law to list recommendations and precautions.

2. Weather conditions are important. Winds could carry toxic sprays and dusts to areas not under your control, causing accidental poisoning to the public or domestic animals.

3. Smoking is not permitted while pesticides are being handled.

4. All pesticides must be handled in well-vetilated areas to minimize inhalation of toxic vapors.

5. Shower and washing facilities must be near pesticide mixing areas.

6. Any contamination of skin, particularly with liquid concentrations or solutions, must be immediately washed off with detergent and water.

7. Protective clothing is used in conjunction with respiratory protective devised to prevent skin contact and inhalation of pesticides. Recommended articles of protective clothing are rubber aprons, coveralls, chemical splash goggles, safety shoes, and hard hats. A lightweight water and chemical resistant throw away type protective clothing that is impervious to herbicides is now available. In warm geographical areas this type of lightweight protective clothing would be beneficial in reducing physical stress to applicators. Additional protection is afforded by protective skin cream.

8. Clothing contaminated by spillage must be removed immediately and thoroughly laundered before wearing. Special care is required to prevent contamination of the inside of gloves.

9. Approved respirators must be worn while pesticides are being mixed, and when dusts or liquids are being handled or sprayed. Care should be exercised when selecting the respirator type to insure that it is designated specifically for the substance to be used. Each respirator must be labeled and approved by the U.S. Department of Agriculture or NIOSH. Filters or canisters must be changed after 8 hours use and more often if odor of the pesticide is detected. (Always have extra cartridges available when needed).

10. Pesticide storage, mixing, and formulation facilities:

(a) All pesticides must be stored in a dry, well ventilated, separate room, building, or covered area not accessible to unauthorized personnel or the public and placed under lock and key.

(b) Identification signs should be placed on rooms, buildings, and fences to advise of the contents and warn of their hazardous nature.

(c) Where applicable, the outside of each storage area should be labeled with “Danger,” “Poison,” and “Pesticide Storage” signs.

(d) Fire extinguishers must be installed near the door of materiel storage rooms. Diluted oil based pesticides are flammable and must be stored separate from other materials.

(e) All pesticide storage, mixing, and formulation areas must have adequate ventilation in order to reduce inhalation of toxic vapors. Sparkproof lighting fixtures should be installed in closed storage areas to eliminate ignition hazards.

11. Empty pesticide containers must be disposed of properly. Do not burn them. When herbicides or defoliants volatilize the resulting vapors may be poisonous to humans, and they may damage nearby plants, crops, or shrubbery; also, pesticides or defoliants containing chlorates may be a serious fire hazard when heated.

12. Glass pesticide containers should be disposed of by breaking. Chop holes in top, bottom, and sides of metal containers or crush them so they cannot collect water or be reused. After breaking or puncturing them, bury the containers at least 18 inches deep in an isolated area provided for this purpose, away from water supplies or high water tables. Records to locate such buried pesticides within the landfill site should be maintained. Post warning signs.

13. Safety programs developed for the safe handling and mixing of toxic chemicals should be coordinated with the Safety Office prior to implementation.
