Advantage Good Agricultural Practices Manual

6.3 Storage of Potentially Hazardous Products

Hazardous substances such as fuel, pesticides or animal health products that are not stored properly can:

  • Be accidentally used for an unintended purpose
  • Cause contamination in the event of a spill or leak
  • Become ineffective

This Good Agricultural Practice applies to:

All farms.

Examples of potentially hazardous products: Lubricants and fuel; pesticides and seed treated with pesticides; cleaning and sanitizing products; and animal health products such as medicated feed, antibiotics and vaccines.


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.

To sign up for a workshop and obtain a copy of the workbook, contact the Ontario Soil and Crop Improvement Association (OSCIA) at 1-800-265-9751 or visit Ontariosoilcrop.org for more information.

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:

  • Containers to rust
  • Labels to deteriorate
  • Bags to split

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.

Check containers

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:

  • Poison Information Centre 1-800-268-9017
  • Spills Action Centre 1-800-268-6060
  • Local Ontario Ministry of the Environment office
  • Local numbers for doctor, fire department, police

Keep absorbent materials such as kitty litter nearby to clean up small spills.

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:

  • Chemical (or Pesticide) Storage
  • Authorized Persons Only
  • WARNING

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:

More information regarding storage of animal health products and medicated feed

To prevent inadvertent use of animal health products and medicated feeds and to guard against improper storage conditions or storage in undesignated areas, all medications should be:

  • Stored in a designated "medication" storage area such as the farm office, refrigerator or utility room
  • Clearly labelled
  • Stored in a clean, dry location according to their label requirements
  • Kept in a secured location with a lock, if possible


Records to keep

Where possible, keep product labels, package inserts, or MSDSs for all? the potentially hazardous products that are stored.


Did you know?
  • Most vaccines are temperature-sensitive and need to be stored between 2°C and 8°C.
  • Modified live vaccines will lose their effectiveness if stored at room temperature.
  • Some animal health products (such as Distosel, a selenium complex) will lose their effectiveness if they are frozen.

Did you know?

Under the Environmental Protection Act, spills that cause or are likely to cause adverse effects must be reported to the Ontario Ministry of the Environment (MOE) and the local municipality.


If you need an audit

Be prepared for the auditor to:

  • Request a site map of the farm to demonstrate where designated storage for potentially hazardous products are located
  • Observe how potentially hazardous products are stored (e.g. securely, according to label direction)


Laws and regulations that apply

Pesticides Act, R.S.O. 1990, c. P. 11, Regulation 914 sets out requirements for storage of pesticides in s. 119 to 123 that must be followed to avoid pesticide contamination of water and impairment of human health and safety. These requirements include provisions for warnings, ventilation, notification and no floor drains. These are reinforced by Guideline B-15 Use and Storage of Pesticides in and around Water, Queen's Printer for Ontario, 2004, #4650e. In addition, the federal Pest Control Products Act (Canada), R.S. 1985, c. P-9, s. 4 (1) specifies that no person shall manufacture, store, display, distribute or use any pest control product under unsafe conditions.

The Pest Control Products Regulations, C.R.C., c. 1253 specifies other conditions for the storage and display of pest control products. S. 43 requires that a pest control product shall be stored and displayed in accordance with any conditions set forth on the label, and if bearing the POISON symbol superimposed on the DANGER symbol, it shall be stored and displayed apart from food for humans or feed for animals in a separate room or separated by a physical barrier so as to avert the contamination of the food or feed.


Other legislation to be aware of

To the extent that chemicals, agrochemicals and animal health products are toxic or hazardous, the Occupational Health and Safety Act, 1990, c. O. 1, s. 26 [as of June 30, 2006 – see O. Reg. 414/05 Farming Operations] will require training of staff in their safe use and storage. The Livestock Medicines Act, R.S.O. 1990, c. L. 23 and Regulations R.R.O. 1990, Reg. 730 provide for standards for maintenance, handling and storage of livestock medicines that apply to licensed sellers.
