6.3 Storage of Potentially Hazardous Products
Hazardous substances such as fuel, pesticides or animal health products that are not stored properly can:
This Good Agricultural Practice applies to:
The Environmental Farm Plan Workbook
The Environmental Farm Plan Workbook is an excellent resource. It outlines
all requirements for the storage and handling of pesticide, fertilizer
and petroleum products.
What needs to be done
Store all potentially hazardous products in a designated and secure location, according to label, package or Material Safety Data Sheet (MSDS) instructions and separately from non-chemical products.
How to do it
Choose a designated storage location
Keep potentially hazardous products physically separated from anywhere that food, seed or fertilizers are handled, packed or stored to prevent cross- contamination.
Store potentially hazardous products in a dry location to prevent moisture from causing:
Locate storage of products away from water sources and areas prone to flooding so that run-off or drainage water from the storage area cannot contaminate ground or surface water.
Consider developing a farm map to record each storage location.
Allow only authorized workers to have access to storage areas. Keep storage areas locked where necessary.
Read the product label for specific storage instructions
Store pesticides and animal health products according to manufacturers' label, package or MSDS instructions.
If chemicals are being stored over the winter, be aware that storage
areas may need to be insulated or heated to protect products from freezing.
Keep products in their original containers.
Keep containers sealed where possible.
Routinely check containers for signs of deterioration (e.g. rust, leaks, loose caps, etc.) and replace the container or dispose of the product when damage is noticed.
If a container is leaking, transfer the product to a replacement container made of similar material. For example, do not transfer a product that was originally stored in a brown glass jar into a clear plastic container. Label the new container (see below).
Make sure all containers have accurate, easy-to-read labels. Replace deteriorated labels. When you re-label products, include: the trade name of the product,the concentration of each active ingredient and the Pest Control Act Registration Number or the Drug Identification Number.
Dispose of expired products
Dispose of any stored products that have reached their expiry date. Refer to 6.4 Storage and Disposal of Farm Wastes in this manual for details on the proper disposal options.
Be prepared for emergencies - spills, fires and poisonings
Consider preparing a site plan that shows where you store potentially hazardous products, as well as the location of all water sources, including wells. Share this information with emergency personnel when necessary.
Post a list of emergency contact numbers near the chemical storage. Include:
Keep absorbent materials such as kitty litter nearby to clean up small
More information regarding storage of pesticides
Store herbicides away from other pesticides such as insecticides and fungicides as the vapours they give off can contaminate other products.
Do not store treated seed in the pesticide storage area as it could become contaminated with other pesticides.
The Ontario Pesticides Act has additional requirements for pesticide storage. Warning signs must be posted on all doors to the pesticide storage area. These signs must have the words:
You can order your signs from the Farm Safety Association at 1-800-361-8855.
The following table outlines the Ontario Ministry of the Environment
storage requirements for all classifications of pesticides:
