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.
