Nope. Hand warmers are actually pretty safe. The ingredients are iron powder, activated charcoal, vermiculite, sodium chloride, water and iron powder. There are no reports of elemental iron or iron oxides ingestion causing iron toxitcity.
The primary active ingredients inside the package are granules of iron, salt and water. The salt and water serve to catalyze the oxidation of iron with oxygen gas in the air forming rust. This process is exothermic, and you can really heat things up by adding a stream of pure oxygen to the handwarmer!
Vermiculite is a mineral that absorbs water. It helps keep the amount of water inside the packet in check so that the oxidization process can continue. Activated charcoal helps disperse the heat evenly so you don't have any hot spots against your skin, and it controls the pace of the reaction.
Air-activated chemical warmers consist of finely divided (powdered) iron, sodium chloride, and charcoal, enclosed in a gas permeable pouch. The pouch is stored inside an airtight wrapper until ready to use.
Our HotHands® family of air activated warmers all contain a mixture of natural ingredients that when exposed to air react together to produce heat. This is accomplished through an extremely fast oxidation process.
EPA's investigation (https://www.epa.gov/asbestos/protect-your-family-asbestos-contaminated-vermiculite-insulation) into these products indicates that consumers face only a minimal health risk from using vermiculite products at home or in their gardens.
Can Hand Warmers Catch Fire? One of the most crucial safety concerns is whether hand warmers can catch fire. While they are generally safe, improper use can lead to overheating or fire hazards. It's essential to follow the instructions provided by the manufacturer to ensure safe usage.
Leave it alone. If vermiculite insulation is disturbed, it may release asbestos fibers into the air. At this point the safest and easiest option for intact insulation is to leave it alone.
Our warmers have a shelf life of 3-4 years. The exact expiration date is printed on the box. Are your warmers TSA approved? Absolutely, according to our (SDS) Grabber - Safety Data Sheet and HotHands - Safety Data Sheet.
Most hand warmers are not designed to get wet, as moisture can interfere with the chemical reaction that generates heat.
HotHands warmers are made of natural materials including iron powder, water, salt, activated charcoal and wood fiber. Once removed from the specially designed outer packaging the exposure to air activates the ingredients and the warmer begins to build heat.
Unopened, these hand warmers can last for several years. When it comes to disposal, consider the environmental impact. Most hand warmers are not recyclable due to the chemicals they contain. Therefore, the best action is to dispose of them in the trash.
Hand Warmers, Toe Warmers, Body Warmers
Disposable warming pads using carbon, charcoal, and iron compounds, Hot Hands, Little Hotties, etc. These air-activated body-warming pads are not regulated as hazardous materials for transportation and may be carried in carry-on or checked baggage.
While the iron ingredients in hand warmers are the main toxic concern, all parts of the hand warmer, including the outer fabric covering, can make your dog sick if ingested. Single-use hand warmers are primarily made up of iron powder and activated charcoal, and they have a fabric-type outer covering.
Although all HotHands® warmers are safe to handle and use, some people with sensitive skin (especially young children, Diabetics and the elderly) may have reduced sensation to heat.
HotHands – Kobayashi Americas. Hothands® Hand Warmers are single use, air-activated heat packs that provide everyday warmth and are ideal for keeping your body warm when the temperature gets cold.
However, after prolonged exposure, the skin can be harmed, he said. After 30 minutes, low-heat burns can manifest as a burning sensation, he said, adding that the resulting rashes do not usually blister, and there would be more itchiness than pain.
In insulation, vermiculite is pebble-like, blown-in, and usually gold or light brown in color. The sizes of vermiculite products range from very fine particles to large (coarse) pieces nearly an inch long.
Coconut coir, also known as coco coir, is popular with a wide range of consumers: container gardeners, hydroponic growers, commercial nurseries, and even homeowners trying their hand at indoor gardening. Part of this explosion in popularity is due to its sustainability, benefits, and similarity to soil and peat moss.
To use, place the handwarmers in the microwave for 30 seconds to a minute (or on top of a radiator for 30 minutes). Then place one in each of your child's coat pocket to keep their hands warm.
How many times can you reuse hand warmers? You can reuse hand warmers throughout the 12 hour period after activating them, but can't be reactivated after opening the pack. Toe warmers last up to 7 hours and body warmers last up to 12 hours.
Generally, disposable hand warmers last between 6 and 12 hours, depending on the brand and the conditions in which they are used.
