Safe handling and storage of farm chemicals
Explain how protective clothing, correct mixing, application precautions, equipment cleaning and secure storage reduce chemical risks.

The 2026 update changes only a weblink; Cambridge reports no significant teaching changes for the 2027–2028 or 2029–2031 cycles. Exams are in the November series, and the qualification is not available in every administrative zone; confirm entry with your centre. Centre-selected local crop, weed, pest, disease and livestock examples must be checked against local agriculture.

Quick readiness check
What should guide the handling and dilution of a farm chemical?
What you will learn
- Describe safe handling before, during and after approved use.
- Explain safe storage for toxic chemicals and flammable materials.
- Recognise that specific products and procedures are governed by labels and local law.
Prevent exposure and pollution
Farm chemicals can be toxic, irritant, corrosive or flammable. The product label and local regulations specify permitted use, protective clothing, dilution, mixing, application and disposal.
Only trained and authorised people should handle a product. Use specifically designed protective clothing, follow label directions, avoid contact and drift, protect water and people, and never improvise a mixture or dose.
Clean and store safely
Clean spraying equipment only using the approved method and prevent washings from polluting drains, soil or water. Keep people and animals away during handling and observe any required re-entry or disposal precautions.
Store chemicals in their original, labelled containers in a secure, ventilated, designated area, separated from food, feed, children and ignition sources as required by the product and local rules. Flammable fuels require suitable fire precautions.

What should guide the handling and dilution of a farm chemical?
Worked example
A worker finds an unlabelled container beside a sprayer. State the safe next steps without guessing its contents.
Show the worked solution
- Do not open, smell, mix or use the container.
- Keep people and animals away and inform the responsible trained supervisor.
- Follow local hazardous-material procedures to identify, secure and dispose of it lawfully.
Answer An unlabelled chemical is an unknown hazard. Do not handle it; isolate the area and follow qualified local procedures.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
Explain why protective clothing and correct dilution are both needed when a trained adult uses an approved farm chemical.
Give me a hint
Consider exposure routes and concentration; do not supply a dose.
Compare my reasoning
- Protective clothing reduces contact through skin, eyes or clothing.
- Correct dilution follows the product label and helps prevent over- or under-concentration.
- Training, weather, equipment, bystander protection and local law also affect safe handling.
Protective clothing reduces exposure; label-correct dilution controls concentration. Neither replaces training and all other precautions.
Look for these in your work
- Exposure reduction explained
- Label use included
- Controls not treated as sufficient alone
A sprayer needs cleaning after an approved application. Explain how to prevent cleaning water from polluting the environment.
Give me a hint
Use the label and local procedure, and avoid directing washings to drains or water.
Compare my reasoning
- Keep people and animals away and follow the product's specified cleaning instructions.
- Contain and manage washings according to the label and local rules rather than releasing them to drains, streams or bare soil.
- Store, reuse or dispose of residues only through the approved method and record the action where required.
Cleaning must follow product instructions and local hazardous-waste rules. Washings should not enter water or an uncontrolled location.
Look for these in your work
- Approved procedure used
- Pollution pathway avoided
- Residue management included
A farm store contains insecticide, herbicide and fuel. Identify a safe storage review checklist.
Give me a hint
Focus on segregation, labels, access, ventilation, ignition and spill response.
Compare my reasoning
- Check that containers remain correctly labelled, closed and in good condition in a secure designated store.
- Separate incompatible or flammable materials as required, protect from heat and ignition, and restrict access.
- Check ventilation, spill containment, emergency information and lawful disposal arrangements with a trained responsible person.
Storage must match each product's label and local requirements, prevent access and ignition, and provide appropriate containment and emergency procedures.
Look for these in your work
- Labels and security checked
- Fire and compatibility considered
- Emergency readiness included
Common mistakes
- Assuming gloves alone make any product safe
- Rinsing equipment into a drain
- Transferring chemicals to an unlabelled bottle
- Storing pesticides beside food or animal feed
