Scope and purpose40 C.F.R., § 170.301.

This regulation is primarily intended to reduce the risks of illness or injury to workers and handlers resulting from occupational exposures to pesticides used in the production of agricultural plants on agricultural establishments. It requires agricultural employers and commercial pesticide handler employers to provide specific information and protections to workers, handlers and other persons when pesticides are used on agricultural establishments in the production of agricultural plants. It also requires handlers to wear the labeling-specified clothing and personal protective equipment when performing handler activities, and to take measures to protect workers and other persons during pesticide applications.
[Statutory Authority: RCW 15.58.040, 17.21.030 and chapter 34.05 RCW. WSR 18-01-054, § 16-233-006, filed 12/13/17, effective 1/13/18.]

Applicability40 C.F.R., § 170.303.

(1) This regulation applies whenever a pesticide product bearing a label requiring compliance with this chapter is used in the production of agricultural plants on an agricultural establishment, except as provided in subsections (2) and (3) of this section.
(2) This regulation does not apply when a pesticide product bearing a label requiring compliance with this chapter is used on an agricultural establishment in any of the following circumstances:
(a) As part of government-sponsored public pest control programs over which the owner, agricultural employer and handler employer have no control, such as mosquito abatement and Mediterranean fruit fly eradication programs.
(b) On plants other than agricultural plants, which may include plants in home fruit and vegetable gardens and home greenhouses, and permanent plantings for ornamental purposes, such as plants that are in ornamental gardens, parks, public or private landscaping, lawns or other grounds that are intended only for aesthetic purposes or climatic modification.
(c) For control of vertebrate pests, unless directly related to the production of an agricultural plant.
(d) As attractants or repellents in traps.
(e) On the harvested portions of agricultural plants or on harvested timber.
(f) For research uses of unregistered pesticides.
(g) On pasture and rangeland where the forage will not be harvested for hay.
(h) In a manner not directly related to the production of agricultural plants including, but not limited to, structural pest control and control of vegetation in noncrop areas.
(3) Where a pesticide product's labeling-specific directions for use or other labeling requirements are inconsistent with requirements of this chapter, users must comply with the pesticide product labeling, except as provided for in WAC 16-233-301, 16-233-306, and 16-233-316.

Definitions40 C.F.R., § 170.305.

Terms used in this chapter have the same meanings they have in the Federal Insecticide, Fungicide, and Rodenticide Act, as amended. In addition, the following terms, when used in this chapter, shall have the following meanings:
(1) "Agricultural employer" means any person who is an owner of, or is responsible for the management or condition of, an agricultural establishment, and who employs any worker or handler.
(2) "Agricultural establishment" means any farm, forest operation, or nursery engaged in the outdoor or enclosed space production of agricultural plants. An establishment that is not primarily agricultural is an agricultural establishment if it produces agricultural plants for transplant or use (in part or their entirety) in another location instead of purchasing the agricultural plants.
(3) "Agricultural plant" means any plant, or part thereof, grown, maintained, or otherwise produced for commercial purposes, including growing, maintaining or otherwise producing plants for sale or trade, for research or experimental purposes, or for use in part or their entirety in another location. Agricultural plant includes, but is not limited to, grains; fruits and vegetables; wood fiber or timber products; flowering and foliage plants and trees; seedlings and transplants; and turf grass produced for sod. Agricultural plant does not include pasture or rangeland used for grazing.
(4) "Application exclusion zone" means the area surrounding the application equipment that must be free of all persons other than appropriately trained and equipped handlers during pesticide applications.
(5) "Chemigation" means the application of pesticides through irrigation systems.
(6) "Closed system" means an engineering control used to protect handlers from pesticide exposure hazards when mixing and loading pesticides.

If a pesticide with product labeling that requires a restricted-entry interval equal to or less than forty-eight hours is applied to an outdoor production area, the agricultural employer must notify workers of the application either by posting warning signs in accordance with subsection (2) of this section or by providing workers with an oral warning in accordance with subsection (3) of this section.
(iv) Enclosed space production areas subject to restricted-entry intervals greater than four hours. If a pesticide with product labeling that requires a restricted-entry interval greater than four hours is applied to an enclosed space production area, the agricultural employer must notify workers of the application by posting warning signs in accordance with subsection (2) of this section.
(v) Enclosed space production areas subject to restricted-entry intervals equal to or less than four hours. If a pesticide with product labeling that requires a restricted-entry interval equal to or less than four hours is applied to an enclosed space production area, the agricultural employer must notify workers of the application either by posting warning signs in accordance with subsection (2) of this section or by providing workers with an oral warning in accordance with subsection (3) of this section.
(b) Exceptions. Notification does not need to be given to a worker if the agricultural employer can ensure that one of the following is met:
(i) From the start of the application in an enclosed space production area until the end of any restricted-entry interval, the worker will not enter any part of the entire enclosed structure or space.
(ii) From the start of the application to an outdoor production area until the end of any restricted-entry interval, the worker will not enter, work in, remain in, or pass on foot through the treated area or any area within 1/4 mile of the treated area on the agricultural establishment.
(iii) The worker was involved in the application of the pesticide as a handler, and is aware of all information required in subsection (3)(a) of this section.
(2) Requirements for posted warning signs. If notification by posted warning signs is required pursuant to subsection (1) of this section, the agricultural employer must, unless otherwise prescribed by the label, ensure that all warning signs meet the requirements of this subsection. When several contiguous areas are to be treated with pesticides on a rotating or sequential basis, the entire area may be posted. Worker entry is prohibited for the entire area while the signs are posted, except for entry permitted in WAC 16-233-306.
(a) General. The warning signs must meet all of the following requirements:
(i) Be one of the three sizes specified in (c) of this subsection and comply with the posting placement and spacing requirements applicable to that sign size.
(ii) Be posted prior to but no earlier than twenty-four hours before the scheduled application of the pesticide.
(iii) Remain posted throughout the application and any restricted-entry interval.
(iv) Be removed or covered within three days after the end of the application or any restricted-entry interval, whichever is later, except that signs may remain posted after the restricted-entry interval has expired as long as all of the following conditions are met:
(A) The agricultural employer instructs any workers on the establishment that may come within 1/4 mile of the treated area not to enter that treated area while the signs are posted.
(B) The agricultural employer ensures that workers do not enter the treated area while the signs remain posted, other than entry permitted in WAC 16-233-306.
(v) Remain visible and legible during the time they are required to be posted.
(b) Content.
(i) The warning sign must have a white background. The words "DANGER" and "PELIGRO," plus "PESTICIDES" and "PESTICIDAS," must be at the top of the sign, and the words "KEEP OUT" and "NO ENTRE" must be at the bottom of the sign. Letters for all words must be clearly legible. A circle containing an upraised hand on the left and a stern face on the right must be near the center of the sign. The inside of the circle must be red, except that the hand and a large portion of the face must be in white. The length of the hand must be at least twice the height of the smallest letters. The length of the face must be only slightly smaller than the hand. Additional information such as the name of the pesticide and the date of application may appear on the warning sign if it does not detract from the size and appearance of the sign or change the meaning of the required information. An example of a warning sign meeting these requirements, other than the size and color requirements, follows:
(ii) The agricultural employer may replace the Spanish language portion of the warning sign with equivalent terms in an alternative non-English language if that alternative language is the language read by the largest group of workers at that agricultural establishment who do not read English. The alternative language sign must be in the same format as the original sign and conform to all other requirements of (b)(i) of this subsection.
(c) Size and posting.
(i) The standard sign must be at least fourteen inches by sixteen inches with letters at least one inch in height.
(ii) When posting an outdoor production area using the standard sign, the signs must be visible from all reasonably expected points of worker entry to the treated area, including at least each access road, each border with any worker housing area within one hundred feet of the treated area and each footpath and other walking route that enters the treated area. Where there are no reasonably expected points of worker entry, signs must be posted in the corners of the treated area or in any other location affording maximum visibility.
(iii) When posting an enclosed space production area using the standard sign and the entire structure or space is subject to the labeling-specified restricted-entry interval and the post-application entry restrictions specified in WAC 16-233-116, the signs must be posted so they are visible from all reasonably expected points of worker entry to the structure or space. When posting treated areas in enclosed space production using the standard sign and the treated area only comprises a subsection of the structure or space, the signs must be posted so they are visible from all reasonably expected points of worker entry to the treated area including each aisle or other walking route that enters the treated area. Where there are no reasonably expected points of worker entry to the treated area, signs must be posted in the corners of the treated area or in any other location affording maximum visibility.
(iv) If a smaller warning sign is used with "DANGER" and "PELIGRO" in letters at least 7/8 inch in height and the remaining letters at least 1/2 inch in height and a red circle at least three inches in diameter containing an upraised hand and a stern face, the signs must be posted no farther than fifty feet apart around the perimeter of the treated area in addition to the locations specified in (c)(ii) or (iii) of this subsection.
(v) If a smaller sign is used with "DANGER" and "PELIGRO" in letters at least 7/16 inch in height and the remaining letters at least 1/4 inch in height and a red circle at least one and a half inches in diameter containing an upraised hand and a stern face, the signs must be posted no farther than twenty-five feet apart around the perimeter of the treated area in addition to the locations specified in (c)(ii) or (iii) of this subsection.
(vi) A sign with "DANGER" and "PELIGRO" in letters less than 7/16 inch in height or with any words in letters less than 1/4 inch in height or a red circle smaller than one and a half inches in diameter containing an upraised hand and a stern face will not satisfy the requirements of this chapter.
(3) Oral warnings - Requirement. If oral notification is required pursuant to subsection (1) of this section, the agricultural employer must provide oral warnings to workers in a manner that the workers can understand. If a worker will be on the establishment when an application begins, the warning must be given before the application begins. If a worker arrives on the establishment while an application is taking place or a restricted-entry interval for a pesticide application is in effect, the warning must be given at the beginning of the worker's work period. The warning must include all of the following:
(a) The location(s) and description of any treated area(s) subject to the entry restrictions during and after application specified in WAC 16-233-111 and 16-233-116.
(b) The dates and times during which entry is restricted in any treated area(s) subject to the entry restrictions during and after application specified in WAC 16-233-111 and 16-233-116.
(c) Instructions not to enter the treated area or an application exclusion zone during application, and that entry to the treated area is not allowed until the restricted-entry interval has expired and all treated area warning signs have been removed or covered, except for entry permitted by WAC 16-233-306.

Once personal protective equipment is worn in a treated area, it must be removed before reentering the cab to prevent contamination of the cab.
(c) Handlers may substitute a long-sleeved shirt, long pants, shoes and socks for the labeling-specified personal protective equipment for skin and eye protection. If a filtering facepiece respirator (NIOSH approval number prefix TC-84A) or dust/mist filtering respirator is required by the pesticide product labeling for applicators, then that respirator need not be worn inside the enclosed cab if the enclosed cab has a properly functioning air ventilation system which is used and maintained in accordance with the manufacturer's written operating instructions. If any other type of respirator is required by the pesticide labeling for applicators, then that respirator must be worn.
(6) Aerial applications.
(a) Use of gloves. The wearing of chemical-resistant gloves when entering or leaving an aircraft used to apply pesticides is optional, unless such gloves are required on the pesticide product labeling. If gloves are brought into the cockpit of an aircraft that has been used to apply pesticides, the gloves shall be kept in an enclosed container to prevent contamination of the inside of the cockpit.
(b) Open cockpit. Handlers applying pesticides from an open cockpit aircraft must use the personal protective equipment specified in the pesticide product labeling for use during application, except that chemical-resistant footwear need not be worn. A helmet may be substituted for chemical-resistant headgear. A helmet with a face shield lowered to cover the face may be substituted for protective eyewear.
(c) Enclosed cockpit. Persons occupying an enclosed cockpit may substitute a long-sleeved shirt, long pants, shoes, and socks for labeling-specified personal protective equipment.
(7) Crop advisors.
(a) Provided the conditions in (b) through (d) of this subsection are met, crop advisors and their employees entering treated areas to perform crop advising tasks while a restricted-entry interval is in effect may substitute either of the following sets of personal protective equipment for the personal protective equipment specified on the pesticide labeling for handler activities:
(i) The personal protective equipment specified on the pesticide product labeling for early entry.
(ii) Coveralls, shoes plus socks and chemical-resistant gloves made of any waterproof material, and eye protection if the pesticide product labeling applied requires protective eyewear for handlers.
(b) The application has been complete for at least four hours.
(c) No such entry is allowed until any inhalation exposure level listed in the pesticide product labeling has been reached or any ventilation criteria required in WAC 16-233-111 (2)(c) or the pesticide product labeling have been met.
(d) The crop advisor or crop advisor employee who enters a treated area during a restricted-entry interval only performs crop advising tasks while in the treated area.
