Prep Course

Front 1

Fieldworker Safety Precautions

(Supervisor Requirements)

Back 1

There is risk to field workers within treated area

• field posting requirements
• activities prohibited during re-entry intervals
• where to go for emergency medical care
• usual symptoms of organophosphate & carbamate poisoning

Front 2

Hazard Communication To Field Workers

(information provided & where workers can find this information)

Back 2

• copy of DPR pesticide safety leaflet - Pesticide Safety for Farmworkers (A9), must be completed by employer before posting
• pesticide use records of pesticides applied to fields
• MSDS for each pesticide applied
• employees (or their representatives, including physicians) access to information asap (48 hrs)

Front 3

Fieldworker Safety Training Subjects

(must be given a minimum of every 5 years)

Back 3

• routine decontamination & thorough washing after pesticide exposure
• restricted-entry interval (REI) posting
• where workers may encounter pesticides & their residues
• routes of exposure: skin (dermal), mouth (oral), lungs (respiratory) & eyes (ocular)
• pesticide hazards - chronic, acute, delayed effects & sensitization effects
• common signs & symptoms of overexposure
• first aid, decontamination, eye flushing & emergency medical attention
• warnings about taking pesticides/pesticide containers home
• hazard communication requirements
• employee right to info about pesticides that have been used in their workplace

Front 4

Treated Field

Back 4

a field that has received a pesticide application for a period of 30 days + any REI. (Ex: field treated with with a pesticide that has a 3-day REI, it would be considered a treated field for 33 days.)

Front 5

Who can provide fieldworker safety training?

Back 5

• certified applicator
• biologist from CAC
• UC farm advisor
• licensed pest control advisor
• registered professional forester
• a person who has completed a DPR-approved training program
• a person otherwise approved by DPR

Front 6

Emergency Medical Care

Back 6

• employers provide name, address & phone of nearest medical facility (info must be on site)
• if employee is suspected of being ill/injured due to pesticide use, employer must make sure employee is taken immediately to medical facility (cannot drive themselves)
• copy of pesticide label should be brought to ER

Front 7

Decontamination Facilities for Field Workers

Back 7

• employers must provide adequate water, soap & single-use towels for hand and face washing
• provide water for emergency eye flushing
• facility must be within 1/4 mile of nearest point of vehicular access
• water provided must be potable & at a temperature that will not cause illness/injury

Front 8

Restricted Entry Intervals (REIs)

(Fieldworker Exposure)

Back 8

• except in case of life-threatening emergencies employees are prohibited from entering a treated field before spray has dried/dust has settled - standard waiting period 24 hours
• spray dried/dust settled standard, can vary depending upon label, found in DPR regs - in case of inconsistency between REI & DPR, follow REI

Front 9

Reasons for Entering a Field During an REI

Back 9

• Pesticide Handling Activities (PPE required)
• "No Contact" Activities (contact with treated soil, foliage, etc using closed cab)
• Limited Contact Activities
• Other, Specific Activities

Front 10

Limited Contact with Treated Foliage

Back 10

• activities necessary & unforseen
• REI is not for pesticide w/ oral notification and field positioning requirements
• no inhalation exposure standards exceeded
• exposure limited to the feet, legs below knees, hands & forearms
• PPE is worn
• time in the treated field doesn't exceed 8 hrs in a 24-hour period

Front 11

Entering Field During REI - Other Specific Activities

Back 11

• four hours have passed since application
• inhalation exposure does not exceed label/regulation standard
• PPE is worn
• time in treated field doesn't exceed 1 hr in 24-hour period

Front 12

REI Adjustments

Back 12

• Organophosphate Tank Mix (2 pesticides)
• No foliage
• Rainfall or Irrigation
• Low Rainfall Areas (increase)
• Chemical Analyses

Front 13

Organophosphate Tank Mix

(REI Adjustment - Sum)

Back 13

• mixture of two or more organophosphate pesticides is applied, the reentry interval is adding longest applicable re-entry + 50% of the next longest.
• Ex: Pesticide A (24 day re-entry and Pesticide B (6 days) - A (100%) + B (50%) = 27 day re-entry

Front 14

No Foliage

(REI Adjustment - Decrease)

Back 14

• no foliage on plant being treated -AND-
• any cover crop or weed cover in treated area is not over 4", REI is reduced by 50%
• Does not apply to label-specified REIs, only to regulation-required REIs

Front 15

Rainfall or Irrigation

(REI Adjustment - Decrease)

Back 15

• CAC needs to grant prior approval
• 2" of rainfall within 7 days
• 2" of irrigation within 7 days
• For trees at least 50 gallons applied at one time under pressure & distributed evenly

Front 16

Low Rainfall Areas

(REI Adjustment - Increase)

Back 16

• Areas that average less than 25" of rain annually
• CAC, with valid data that shows 25" standard was exceeded, would cause area to be exempt from required REI increase

Front 17

Chemical Analyses

(REI Adjustment - Decrease)

Back 17

may be reduced (or cancelled) if laboratory analysis reveals crop has no residue or residue levels are below level DPR considers hazardous

Front 18

Field Posting

Back 18

• Required by Labeling - applies when access to field (within 1/4 mile) cannot be adequately controlled
• REI Greater than 7 Days
• Greenhouse Applications - when entrance cannot be adequately controlled

Front 19

Warning Sign Requirements

Back 19

• must be posted at usual points of entry
• if no easily identifiable entry points are identified signs posted at corners
• if next to public ROW & is unfenced signs posted at each corner & at intervals of 600 ft or less

Front 20

Field Posting - Specifics of Signage

Back 20

• warning sign must be legible for duration of REI
• large enough to be legible 25 ft away
• written in English & Spanish (3rd can be added)
• must be posted before application begins
• can't be posted unless application is scheduled within next 24 hrs
• cannot be removed during REI
• must be removed within 3 days after end of REI
