Warning signs are typically used to:

Warning signs are primarily designed to alert individuals about possible hazards in their environment. They serve the purpose of providing a cautionary message that alerts people to potential dangers, enabling them to take necessary precautions. For instance, a sign indicating "wet floor" cautions individuals that the surface is slippery, thus reducing the risk of slips and falls.

While some might think of warning signs as tools to prevent access to hazardous areas or to block off unsafe zones, those functions are more accurately associated with specific safety measures like barriers or prohibitory signs. Furthermore, indicating safety procedures does not fall under the primary purpose of warning signs, which is not about outlining actions to be taken, but rather about informing individuals to be vigilant regarding specific dangers.
