b. Caution Signs. These signs are used to warn against potential hazards or to
caution against unsafe practices such as: stopping machinery to clean, oil, or repair. All

black rectangular panel will be placed at the top of the sign and within it will be the word
"CAUTION" in yellow letters. Additional wording will be added below the word
