Fire proximity suit

A fire proximity suit is like a special kind of outfit that firefighters wear to keep themselves safe from fire. It has a lot of layers and is made of special materials that can resist heat and flame. When a firefighter wears this suit, they can walk close to a fire without getting hurt. It's like a really strong and tough coat that can protect them from getting burned by the hot and dangerous flames. So, when a firefighter has to go into a burning house or building, they put on this special suit to keep themselves safe and do their job.
