A person whose job is to extinguish fires.
The kid above was signing at age 4.
Close "4" handshape, palm orientation facing out on the forehead.
Case study: watch how this child develops the sign FIREFIGHTER on the phonological level from baby to age 3. At age 3, she was able to read the word FIRE as well as fingerspelled it loud.
In the beginning, the palm orientation faced in and the location was on the side of the head. As the toddler's language developed, the palm orientation eventually faced out on the forehead.
