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

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.

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.
