Indoor OSHA warning signs and ANSI danger signs

You should post or mount safety signs and labels inside your facility wherever hazards are present. How do you know which type of signage applies to each hazard? OSHA and ANSI (American National Standards Institute) have created several primary classifications for safety signs. They depend on the severity of the risk:

  • Danger signs: This indoor safety signage alerts workers to the most serious hazards. The signs warn that death or serious injury can result if the hazard is not avoided. On OSHA-compliant signs, the “Danger” signal word is printed in white letters over a red background. A safety alert symbol appears on the left.
  • Warning signs: These indoor safety signs describe hazards that can result in death or serious i njury if not avoided. The safety alert symbol appears to the left of the “Warning” signal word. It’s displayed in black over an orange background.
  • Caution signs: These signs caution workers against potential injuries from unsafe practices. On these OSHA-compliant indoor safety signs, the “Caution” signal word is shown in black over a yellow background. It’s preceded by the safety alert symbol.
  • Biological hazards signs: These indoor workplace safety signs alert workers to biohazards that can pose a risk to their health. They are classified by “Danger,” “Warning” or other signal words depending on the level of risk.
