When thinking of warning signs, it comes to mind those brightly colored signs, indicating a danger ahead or blocking off access to the area. These signs are in place for a reason, and are not to be ignored. However there aren’t always physical, brightly colored signs flashing in your face telling you what danger is about to happen. You have to keep a cautious eye for the area around you. If you feel a wobble in the ladder you are using, it could mean a breakdown in its structural strength. A crack in your hardhat isn’t something you cover up with a sticker, it’s a sign that you need to replace it so it can continue to provide proper protection. The problems and dangers aren’t always right in front of your face, so always stay aware.
