Heating instructions
1. Remove the warmer from the package and shake it 5–6 times to activate the heating process. 2. Wait for 10 minutes, since the warmer must be fully warm before it is put in a confined space (pocket, glove, etc.). 3. Ideally, activate them in an ambient environment of 20°C (at home, in the car, etc.). 4. At 0°C or above 2,000 m altitude, blow on them several times. The warmth and moisture of your breath will accelerate the reaction.
How it works
The warmer is a mix of activated charcoal powder and iron that produces heat through oxidation. The reaction stops: - When all the activated charcoal is gone. The reaction stops completely after about 5 to 6 hours. - In an airtight space (in a rubber boot or with neoprene cycling overshoes). The reaction starts when the warmer is exposed to air.
Restrictions
Hand-warmers should only be used for your hands and should not be used on other parts of the body.
Precautions
Children, the elderly, and persons with disabilities should use this product with caution and supervision. Persons who have diabetes, delicate or sensitive skin, circulation problems, paralysis, damaged nerves, rheumatoid arthritis, are pregnant, or who have any concerns should consult a physician before using the product. Do not apply to frostbitten or desensitized skin. Do not use while sleeping. Do not use in combination with topical analgesics or heating devices.
Good to know
The exothermic reaction begins on the production line: - The mixture is activated, then checked - Once inspected and validated, the pair of hand warmers is inserted in the plastic packet, which stops the reaction and therefore the heat generation. The reaction will start again when the pack is opened and the warmer is exposed to oxygen and humidity.
What should I do if my warmer stops heating after an hour or so? What if it doesn’t get warm enough?
This means that the reaction is suppressed by lack of air. Just remove the warmer and knead it or blow on it to begin the heating process again. You can then put it back in your glove or pocket.
Troubleshooting
The warmer may not be working properly because of: - a lack of air: (if it is enclosed in neoprene, for example). - extreme conditions: in extreme cold, the warmer provides warmth in addition to the ambient temperature. However, it may not sufficiently warm up in extremely low temperatures. - an altitude exceeding 3,000 m, where a lack of oxygen limits the reaction.
Single-use product.
The exothermic reaction consumes the activated charcoal and oxidizes the iron. Once the fuel is spent, the reaction ends and the powder becomes hard.
