Homemade wheat bags
Homemade wheat bags can pose a greater fire and injury risk
because the moisture content and volume of these bags is not known,
and the proper heating time can’t be recommended. The use of a type
of wheat other than buckwheat may increase the risks of overheating,
fires, and burns.
Adding oils to wheat bags
If you add oils to wheat bags, over time you will saturate the
cover cloth and create an added fire risk to the existing danger of
overheating and fire.
Overheating and Fire Risks
Continual heating and drying of the wheat bag may overheat it to
ignition point. When heating it in a microwave, place a cup or bowl
of water in with the wheat bag to reduce this risk.
Spontaneous Combustion
If the wheat bag is kept insulated after initial heating (for
example, placed under bedclothes, or on a car seat in the sun),
spontaneous heating can then occur and the wheat may catch fire.

Do’s and Don’ts
DO
- Buy wheat bags with clear heating instructions.
- Read and follow the manufacturer’s instructions.
- Buy wheat bags which include a manufacturer’s contact details
in case you have a problem.
- Use only as a heat pack for direct application to the body.
- Watch for over-use – an over-cooked odour, a smell of burning,
smoking or charring.
- Leave to cool in a safe area and on a non-combustible surface,
like a kitchen sink.
DO NOT
- Do not use wheat bags as bed warmers.
- Do not over-heat (recommended maximum is three minutes for
manufactured bags).
- Do not reheat the bag until it has completely cooled - which
may be two hours after initial heating.
- Do not leave the microwave unattended when heating a bag.
- Do not store the wheat bag until it is cold.
- Do not use the bag if you observe any problems – contact the
manufacturer.
