Question 1

What is the Poison Control Center phone number in the United States?

Accepted Answer

The national Poison Control Center number is 1-800-222-1222 and is available 24 hours a day, 7 days a week. Pesticide applicators should memorize this number and keep it posted in a visible location.

Question 2

What is the FIRST step when responding to a large pesticide spill?

Accepted Answer

Before approaching any pesticide spill, you must protect yourself by donning appropriate PPE. Attempting to contain or clean up a spill without proper protection can result in serious pesticide exposure to the responder.

Question 3

An applicator splashes pesticide concentrate into their eyes. What is the FIRST action to take?

Accepted Answer

Eye exposure requires immediate flushing with clean water for a minimum of 15 minutes. Time is critical — delaying to make phone calls first allows the pesticide to cause greater damage. Remove contact lenses if present before flushing.

Question 4

A worker ingests a pesticide. The label does NOT mention inducing vomiting. What should be done?

Accepted Answer

Do NOT induce vomiting unless specifically directed by the label or Poison Control. Vomiting can cause additional harm with certain pesticides (especially corrosives or petroleum-based carriers). Always call Poison Control for guidance.

Question 5

How many times must an empty pesticide container be rinsed during the triple rinse procedure?

Accepted Answer

The triple rinse procedure requires exactly three complete rinse cycles. Each cycle involves filling the container approximately one-quarter full with water, agitating vigorously, and emptying the rinse water into the spray tank.

Question 6

After triple rinsing an empty pesticide container, what must be done before disposal?

Accepted Answer

After triple rinsing, containers must be punctured or crushed to prevent them from being reused to store food, water, or other substances. This is required by federal law and prevents accidental poisoning from container reuse.

Question 7

When transporting a pesticide exposure victim to the hospital, what is essential to bring?

Accepted Answer

The pesticide label and SDS contain critical information about active ingredients, toxicity, and first aid treatment that emergency medical personnel need to treat the victim correctly. Never transport an exposure victim without this information.

Question 8

What is the correct first aid procedure for skin exposure to a pesticide?

Accepted Answer

For skin exposure, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. Contaminated clothing must be removed before washing to prevent continued exposure.

Question 9

An applicator inhales pesticide fumes and becomes dizzy. What is the FIRST action?

Accepted Answer

Inhalation exposure requires immediately moving the victim to fresh air away from the contaminated area. If the person loses consciousness or stops breathing, call 911 and begin CPR if trained. Do not re-enter a contaminated area without proper respiratory protection.

Question 10

During a pesticide spill response, after controlling the source and protecting yourself, what is the NEXT step?

Accepted Answer

After controlling the spill source and donning PPE, the next step is to contain the spill to prevent it from spreading to soil, water, or drains. Use absorbent materials, sand dikes, or berms to limit the spill area.

Question 11

What information should you have ready BEFORE calling Poison Control about a pesticide exposure?

Accepted Answer

Poison Control specialists need complete product information to provide accurate guidance. Have the pesticide label ready with the product name, EPA registration number, active ingredients, and details about how, when, and how much exposure occurred.

Question 12

An unconscious pesticide exposure victim is found. What should NOT be done?

Accepted Answer

Never give anything by mouth to an unconscious person — they may aspirate liquids into their lungs, causing additional injury. Call 911, maintain their airway, and wait for emergency medical services.

Question 13

A worker is showing symptoms of organophosphate poisoning: excessive salivation, pinpoint pupils, muscle tremors, and difficulty breathing. What should be done FIRST?

Accepted Answer

Organophosphate poisoning is a medical emergency that requires immediate professional treatment, including possible atropine administration. Emergency medical personnel must know it is organophosphate poisoning to administer the correct antidote. Never attempt to self-administer antidotes.

Question 14

Which of the following is an acceptable alternative to triple rinsing an empty pesticide container?

Accepted Answer

Pressure rinsing using a rinse nozzle that delivers water at 40 PSI for at least 10 seconds per rinse is an accepted alternative to triple rinsing. The rinsate must also be emptied into the spray tank, just as with triple rinsing.

Question 15

A pesticide spill reaches a storm drain leading to a waterway. Which agencies may need to be notified?

Accepted Answer

Pesticide spills reaching waterways may trigger reporting requirements under CERCLA and EPCRA. Depending on the quantity and chemical, the EPA National Response Center, state environmental agency, and local emergency responders may all need to be notified.

Question 16

An applicator has pesticide on their skin and there is no running water available. What is the best immediate action?

Accepted Answer

If water is unavailable, wipe off as much pesticide as possible with a clean dry cloth, then seek running water for a full 15-minute wash as soon as possible. Any delay increases dermal absorption; partial removal is better than no action.

Question 17

Why must contact lenses be removed BEFORE flushing eyes after pesticide exposure?

Accepted Answer

Contact lenses can trap pesticide chemicals between the lens and the eye surface, concentrating the exposure and preventing water from reaching the affected area. They must be removed before beginning the 15-minute eye flush.

Question 18

A large organophosphate spill occurs near a drainage ditch. What is the correct sequence of actions?

Accepted Answer

The correct sequence is: protect yourself with PPE, then prevent the spill from reaching the waterway by blocking the drain, contain with absorbent material, conduct proper cleanup, and report to the appropriate regulatory agencies as required under CERCLA/EPCRA.

Question 19

A worker becomes ill after applying a pesticide in a remote area. The nearest hospital is 45 minutes away. What should be done while transporting the victim?

Accepted Answer

While transporting, someone should call Poison Control to receive real-time guidance and alert the receiving hospital with product information. This allows medical staff to prepare appropriate treatment before the victim arrives.

Question 20

During cleanup of a pesticide spill, an applicator's coveralls become heavily contaminated. What is the correct action?

Accepted Answer

Heavily contaminated PPE that cannot be adequately decontaminated must be placed in a sealed, labeled bag and disposed of according to pesticide label directions and state hazardous waste regulations. Burning or improper disposal is illegal and creates additional hazards.

Question 21

A worker shows SLUDGE symptoms (salivation, lacrimation, urination, defecation, GI upset, emesis) after organophosphate exposure. What are the immediate steps?

Accepted Answer

SLUDGE indicates organophosphate poisoning. Immediate steps include removing from exposure, decontamination, emergency transport, and emergency medical personnel may administer atropine as an antidote.

Question 22

Pesticide splashes directly into a worker's eyes while wearing contact lenses. What is the correct first aid sequence?

Accepted Answer

Flush immediately with water while contacts are in place to remove pesticide. Attempting to remove contacts first delays decontamination and increases exposure. After rinsing, remove contacts if possible. Seek medical care regardless.

Question 23

A pesticide spill occurs on a field 20 feet from a drainage ditch. What is the priority sequence for response?

Accepted Answer

First priority is preventing pesticide from entering waterways by blocking flow or creating barriers. Then contain the spill in place. Finally, notify regulatory agencies and conduct cleanup per regulations.

Question 24

An applicator needs to call Poison Control after pesticide exposure. What critical information should be gathered before the call?

Accepted Answer

Poison Control needs complete information to provide accurate guidance: product specifics (EPA reg number), exposure route, victim demographics (weight for dosing), and timing to assess severity and recommend treatment.

Question 25

A worker has skin exposure to a pesticide concentrate, and no water is immediately available at the application site. What are appropriate interim decontamination steps?

Accepted Answer

Immediate removal of contaminated clothing and wiping excess pesticide reduces absorption until water is available. Rinsing with water is critical but interim removal of concentrate is valuable harm reduction.

Question 26

A worker is found unconscious near a pesticide application area. Which action is NOT appropriate?

Accepted Answer

Mouth-to-mouth resuscitation without a barrier or pocket mask risks the rescuer's exposure to pesticide residue on the victim's face. Other actions are appropriate; rescuers should use a barrier if available.

Question 27

A 2.5-gallon pesticide container must be triple-rinsed before disposal. How much water should be used per rinse cycle?

Accepted Answer

EPA triple-rinse requirements specify rinsing with a volume equal to approximately 10% of the container's capacity per rinse. For a 2.5-gallon container, approximately 2.5 gallons per rinse minimizes pesticide residue.

Question 28

A pesticide spill reaches a storm drain connected to municipal water system. Which agencies must be notified?

Accepted Answer

Pesticide spills reaching surface water or storm drains require notification to EPA and state environmental agencies. Local water systems and emergency responders must also be alerted to protect public health.

Question 29

An inhalation exposure to pesticide vapor occurs in an enclosed space, and the victim is unconscious. A non-trained responder plans rescue without SCBA. What is the concern?

Accepted Answer

Rescue in contaminated atmospheres without SCBA exposes the rescuer to the same pesticide vapor, potentially causing similar or worse effects. Only trained responders with respiratory protection should enter contaminated areas.

Question 30

A pesticide exposure victim is being transported to the hospital. What essential document should accompany the victim?

Accepted Answer

The pesticide label and SDS provide critical toxicological information, ingredients, and recommended medical treatment that emergency physicians need to provide appropriate care.

Question 31

After triple-rinsing a pesticide container, what additional disposal step is required before the empty container can be discarded?

Accepted Answer

EPA regulations require that triple-rinsed containers be punctured, crushed, or perforated before disposal to prevent reuse for food, beverage, or other purposes, which could cause poisoning.

Question 32

A 20-gallon organophosphate pesticide concentrate spill occurs inside a closed storage building with one exit, concrete floor, and no ventilation system. Describe the correct step-by-step response sequence: (A) Evacuate the building immediately to stop exposure, (B) Ventilate the building, (C) Call hazmat/emergency response team, (D) Contain the spill with absorbent material to prevent dispersal, (E) Clean contaminated areas with appropriate cleaners, (F) Document the incident. What is the correct order?

Accepted Answer

Correct response prioritizes life safety first: evacuate all persons from the hazardous enclosed space immediately to prevent inhalation and dermal exposure. Call emergency response (hazmat) to handle professional cleanup of Category I material. Do not attempt self-cleanup in an enclosed space with organophosphate concentrate—this is a professional remediation scenario. Post-emergency documentation completes the response.

Question 33

Two workers are exposed to pesticide vapor in an enclosed space. Worker A is conscious but weak and dizzy; Worker B is unconscious and unresponsive. Ambient organophosphate concentration is unknown. What is the correct triage and immediate response sequence?

Accepted Answer

Life-threatening exposure (unconsciousness) indicates severe systemic toxicity. Priority: immediate evacuation (stop exposure), emergency medical call, position unconscious victim to protect airway, monitor conscious victim. Organophosphate cholinergic effects can rapidly deteriorate. Both victims require immediate professional medical intervention; do not delay evacuation for first aid procedures.

Question 34

A pesticide spill incident occurs: 5 gallons of Category II herbicide concentrate on soil in an agricultural field adjacent to a surface water drainage ditch 40 feet away. The spill occurred at 2 PM on a Monday; rainfall is forecasted for Tuesday. Which agencies should be notified, and why?

Accepted Answer

Spill reporting decision tree requires: chemical identity (herbicide), quantity (5 gallons threshold-exceeding), hazard class (Category II), location risk (water nearby, rain forecast), and movement likelihood. Water contamination risk triggers environmental agency notification. Regulatory thresholds typically require reporting at these spill sizes. Failure to notify creates liability.

Question 35

A worker had skin contact with an organophosphate concentrate approximately 6 hours ago while applying pesticide. There were no immediate symptoms (no burning, no visible irritation). The worker now questions whether medical evaluation is needed. What is the appropriate response?

Accepted Answer

Organophosphate toxicity is dose-dependent and can manifest hours after exposure. Lack of immediate symptoms does not rule out systemic absorption or delayed cholinergic effects. Medical documentation of exposure and worker health status (baseline vital signs, cholinergic symptoms) at time of evaluation supports future treatment decisions if symptoms emerge. Delay risks unrecognized systemic toxicity.
