Welcome to Your Externship Site
Your externship is the bridge between classroom learning and licensed professional practice. On day one, before you ride on a single service call or touch any product, you must complete a formal site orientation. This lesson explains what that orientation covers, why every step matters, and what your supervising applicator expects from you before you leave the yard.
The Site Orientation Tour
Your supervising applicator will walk you through the physical workplace. Pay close attention and take notes on your orientation checklist as you go. Key stops include:
Chemical storage room. Pesticides must be stored in a locked, labeled, well-ventilated area, away from food, feed, and ignition sources. Note which products are on the shelf, how containers are labeled, and where the secondary containment (a berm, tray, or lined cabinet that catches leaks) is located.
Spill kit location. Every professional operation keeps absorbent material, neutralizing agents, personal protective equipment (PPE), and a sealed waste container ready for a spill response. Locate this kit on your first walk-through. You should be able to reach it in the dark or under stress.
First-aid station. Know where the first-aid kit is, whether an eyewash station is present, and who on site holds current first-aid or CPR credentials.
Emergency exits and muster point. Identify every exit from the building and the designated outdoor muster point where staff gather after an evacuation. Emergency phone numbers — including the National Pesticide Information Center (NPIC) and Poison Control — should be posted near each phone and in your field journal.
When the tour is complete, sign and date your written orientation checklist. Your supervising applicator co-signs it. That document is a legal record that you received safety training on a specific date.
Vehicle Inspection
The company service vehicle is a mobile chemical storage and equipment unit. A damaged or improperly loaded vehicle is a liability to you, the public, and the environment. Before departing on any route, complete the daily vehicle inspection log. Check:
Tires, lights, and fluid levels — basic roadworthiness.
Ladder tie-downs — ladders must be secured so they cannot shift during transport.
Chemical segregation — herbicides, insecticides, and rodenticides must be stored separately to prevent cross-contamination. Liquids must be upright and capped. Never store pesticides loose in an unsealed area of the cab.
Pesticide storage compliance — containers must be original, labeled containers or properly labeled secondary containers. No unlabeled material is ever acceptable.
Spill containment in the vehicle — many companies keep a small spill kit in the truck bed; verify it is stocked.
SDS binder — Safety Data Sheets for every product carried must be physically present in the vehicle whenever those products are transported.
Sign and date the log. If you find a defect, report it to your supervisor before departure; do not drive a vehicle you have flagged as unsafe.
PPE Selection and Fit Check
PPE is your last line of defense between your body and a hazardous chemical. Selecting the wrong glove material, the wrong respirator cartridge, or improperly fitting a half-face respirator can be as dangerous as wearing nothing at all.
Before each service type, open the SDS for the product(s) you will apply. Section 8 of every SDS (under OSHA Hazard Communication, 29 CFR 1910.1200) specifies exposure controls and personal protection, including required glove material (e.g., nitrile, neoprene, butyl), eye protection type, and respiratory protection. The pesticide label also carries PPE requirements; the label is a legal document, and you must follow whichever source — label or SDS — requires greater protection.
For your fit check:
1. Select gloves, eye protection, and respirator based on the day's scheduled products and application methods.
2. Don each item and verify fit — gloves should seat above the wrist, goggles should seal without gaps, and a half-face respirator must pass a user seal check (positive- or negative-pressure check per manufacturer instructions).
3. Explain your choices aloud to your supervising applicator. State the hazard each piece of PPE addresses.
4. Record your selections in your daily field journal: date, product name, PPE chosen, and hazard rationale.
Never eat, drink, or smoke while wearing pesticide-contaminated PPE or before washing hands thoroughly.
Emergency Procedures You Must Know Before Riding Out
Your supervising applicator will quiz you verbally before you ride on a call. Be ready to state:
The company's emergency contact number and the site supervisor's cell number.
The address of the current worksite (needed to direct emergency services).
Steps for a pesticide spill: stop the source, protect yourself with PPE, confine the spill, consult the SDS, notify your supervisor, and document the incident.
Steps if a person is exposed: refer to SDS Section 4 (first aid), call Poison Control, and seek medical attention. Do not induce vomiting unless directed by medical personnel.
Location of the nearest hospital or urgent care relative to common service areas.
Meeting the 100% threshold on the verbal quiz is not optional — it is a condition of riding out. Safety compliance on the job site protects you, your employer's license, and the public.
Key terms8
Secondary containmentA physical barrier — such as a berm, drip tray, or lined cabinet — designed to catch leaks or spills from primary pesticide containers and prevent environmental contamination.
Safety Data Sheet (SDS)A standardized document, required under OSHA Hazard Communication, that provides health, safety, storage, and emergency response information for a hazardous chemical; Section 8 specifies required PPE.
Hazard Communication Standard (HazCom)OSHA regulation (29 CFR 1910.1200) requiring employers to inform workers about chemical hazards through labels, SDS, and training; it aligns US practice with the Globally Harmonized System (GHS).
PPE fit checkA hands-on procedure performed before each use to verify that protective equipment — especially respirators and gloves — is correctly sized, properly seated, and free of defects.
User seal checkA quick positive- or negative-pressure test performed by the respirator wearer immediately after donning to confirm the facepiece forms an adequate seal against the face.
Vehicle inspection logA company document completed daily before vehicle departure that records the condition of tires, lights, chemical storage, tie-downs, and safety equipment; serves as a legal record of compliance.
Orientation checklistA written form completed during the first-day site tour confirming that the new worker has been shown emergency exits, spill kits, chemical storage, and first-aid locations; co-signed by the supervisor.
Spill kitA prepared collection of absorbent materials, neutralizing agents, PPE, and sealed waste containers kept ready for immediate use in the event of a pesticide spill at a job site or in a service vehicle.
