Safety

Please read this before you use the hand warmer or the heated jacket. Each line says where it comes from.

Who they're for

These heated goods are sold for grown-ups. They are not for children. (our own store rule)

Never use them on a baby. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

Don't use them on someone who can't feel heat on their skin. That can mean someone who is paralyzed, or someone whose feeling is dulled by age, diabetes, a spinal cord injury, or medicine. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

Don't use them on someone who is asleep or passed out. Don't sleep while one is on. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

Using them

Read and follow the maker's instructions that come with it. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

Heat kept on one spot for a long time can cause a bad burn, even on a low setting. Move it, or take a break. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

Check it before each use. Stop using it if it looks worn or cracked, or if the cord is frayed. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

Turn it off and unplug it when you're not using it. (FDA and CPSC heating pad advisory, 1995, read 2026-10-18)

The advisory above was written for electric heating pads. It is the nearest list of these lines we could find from the US government, so we use it for our heated goods too.
