Are the contents of hand warmers poisonous?
Iron is essential to the growth and development of many biological and bodily systems. However, in large amounts, it can be very toxic. The metals within hand warmers contain amounts of iron that can be toxic to dogs if eaten. Iron poisoning can even be lethal if large amounts are consumed.
What chemicals are in hand warmers?
Most disposable hand warmers contain a mix of iron, water, activated carbon, vermiculite, cellulose, and salt. Once exposed to air, the iron oxidizes and releases heat in the process.
What is the powder inside hand warmers?
IRON POWDER These hotties can reach up to 163 degrees Fahrenheit; military-grade warmers (for heating MREs) can get to upwards of 200 degrees. Manufacturers produce iron powder by either crushing iron or spraying a molten stream with water.
Are hand warmers safe to use?
Are Hand Warmers Safe to Use? Most hand warmers are safe if used properly. Some people, usually children, have very sensitive skin and should not let hand warmers come into direct contact with their skin. Some hand warmer varieties, like catalytic burner warmers, prove to be more dangerous than others.
What does vermiculite do in hand warmers?
Vermiculite is a hydrated magnesium aluminum silicate (duh) that serves as an insulator, regulating the heat reaction a bit, and, very importantly, keeping the warmer from burning up all at once and eating your hand. They generate heat for as long as the oxidization lingers, usually no more than a couple hours at best.
Can hand warmers be used as oxygen absorbers?

Are hand warmers toxic to cats?
If your pet ingests this part of a disposable hand warmer, it's likely that they could experience symptoms of an upset stomach. But, if the hand warmer was unused and ingested by your pet, thermal burns can occur in the stomach and vomiting or diarrhea with blood can be seen.
Why do you shake hand warmers?
It may seem strange, but shaking the hand warmers does speed up the reaction and generates more heat. By shaking the packet, you are increasing the speed of the reaction that takes place, making the disposable hand warmers heat up faster.
Do hand warmers give off co2?
Consumers should not overlook the potential risk of such product just because no naked flame can be seen. Apart from carbon dioxide, carbon monoxide and a weak smell of fuel could be released during operation.
Do hand warmers produce carbon monoxide?
Being a device which burns fuel means that it also consumes oxygen and creates carbon monoxide. With adequate ventilation, this isn't an issue, just something I wanted to mention so you're aware of it. Zippo isn't the first manufacturer to make a catalytic hand warmer, but it's the first one I've had exposure to.
Are butane hand warmers safe?
If you're hunting, don't worry: animals won't be able to smell the butane. It's easy to fill up, and though it does have butane in it, it's safe: The hand warmer heats catalytically, so there's no flame to worry about, since it only smolders to produce heat.
