If used properly, heated gloves are usually extremely safe and effective.There’s little risk of electric shock because no bare wires are exposed inside the gloves. Heated gloves also have a safety shut-off feature that turns them off in the event of a short circuit. The batteries inside the gloves don’t get hot enough to cause the fabric to ignite, either.If you’re still concerned about safety, you may prefer to use gloves that use a chemical heating element.
