Chemicals on the farm can be dangerous

Common agricultural chemicals (agrichemicals) include fuels, solvents, insecticides, herbicides, fungicides, fertilisers and veterinary chemicals. Farmers need to take care when storing, transporting, using and disposing of chemicals to ensure their own safety; their neighbours’ safety and that of the environment.

Any chemical should be treated with extreme caution and only ever used according to the instructions.

Vapours or direct exposure can lead to a variety of acute (short-term) and chronic (long-term) health effects. Health effects can include headache, poisoning, burns, birth defects, nervous system disorders and some cancers. Hazardous materials are required by law to include a Safety Data Sheet (SDS – previously known as a Material Safety Data Sheet or MSDS) and label.

The SDS gives valuable information on how to safely handle the chemical.

Before using any farm chemical, be sure to read the label, understand the SDS and do a chemical users course (such as ChemCert).

Always follow usage instructions

To further reduce the risks, consider replacing hazardous chemicals with less toxic options. Sometimes, a safer form of the product is available.

For example, pellets may be used instead of powder. Agricultural chemicals may be purchased in various concentrations and forms (such as liquids, powders, granules and pellets), depending on their intended use.

Many of the more potent chemicals require the farmer to have completed chemical training to enable purchase and use. Commonly used agrichemicals include:

  • The effects of chemical exposure depend on the type of chemical
  • the degree of exposure. If chemicals are swallowed
  • absorbed through the skin or inhaled as a mist
  • vapour or dust some of the immediate effects can include chemical burns

If you notice any of these symptoms after being exposed to chemicals, seek immediate medical attention. Some long-term effects of chemical exposure can include:

  • nervous system disorders. Manufacturers
  • importers are required to supply a Safety Data Sheet (SDS) that details information on the chemical
  • including: withholding periods – it is the responsibility of the farmers to ensure correct usage
  • that slaughter or production withholding periods are observed

It is important that you research chemicals prior to purchase to ensure that you buy the most suitable and least dangerous chemical available to do the job you require. SDSs can be found online to assist in safe and effective chemical choices and should be thoroughly read before use and kept in an accessible place for reference.

Suggestions for the safe storage of chemicals include: Always follow the manufacturer’s instructions for proper storage.

Keep chemicals in their original containers and do not pour into smaller bottles.

Do not remove labels from containers

Store chemicals in a locked, well-ventilated shed with floors that will contain spills. Store chemicals and appropriate personal protective equipment in different locations. Store the filter(s) from masks separately to contaminated protective equipment when not in use – for example, in a zip-locked bag or an ice-cream container.

Do not store liquid chemicals above solids

Separate different classes of chemicals to prevent reactions

Store animal feeds, seeds and fertilisers separately from other chemicals. Have mop-up materials on hand, such as sand, soil or DrySorb.

Keep ignition sources well away from chemicals

Keep a record of the chemicals you buy, store and use. Suggestions for the safe transporting of chemicals include:

  • Transport chemicals separately from food water animal feeds
  • fertilisers. This applies to transport of household
  • home garden quantities of the chemical
  • as well as bulk transport

Drums of agricultural chemicals should not be transported in enclosed cabins with the driver and passengers.

Secure your load

Carry a written record of the chemicals you are transporting.

Take all appropriate protective gear along with you

Suggestions for the safe use of chemicals include:

  • Ensure anyone using agricultural chemicals is suitably trained to use both the chemical
  • any equipment required for application. Use chemical decanting kits to reduce the risk of spills
  • splashes while mixing chemicals. Only mix the quantity of chemical required for the task at hand

Make sure the decanting and mixing area is well ventilated.

If this is not possible, ensure that recommended personal protective equipment (PPE) is worn for enclosed environments. Follow the manufacturer’s instructions on the label.

Always wear recommended protective clothing such as chemical-resistant gloves, overalls, goggles and appropriate P2 facemasks or a P3 respirator. (Respirator cartridges should provide multi-level gas protection.) Avoid exposing non-target animals or plants. Triple rinse equipment after chemical application and dispose of the rinse water (rinsate) appropriately.

Rinsate contains low concentrations of the chemical from the cleaning process. Suggestions for the safe disposal of chemicals include:

  • Always follow the manufacturer’s instructions for proper disposal of both chemicals
  • rinsate from equipment. Thoroughly triple rinse
  • then puncture empty containers to prevent reuse for other purposes

Return empty containers to the manufacturer or check with your local council about proper disposal methods. Audit your chemical store on a regular basis and dispose of any excess or outdated chemicals in the appropriate manner.

If you think someone is suffering ill effects from chemical exposure: In an emergency ring 911 for an ambulance.

If you can, inform the healthcare workers about what chemicals the person may have been exposed to (take the MSDS with you). Tel: (24 hours, 7 days, United States wide).

If use of a chemical has caused you ill-effects, try to avoid using it in the future.
