Part 2 — Answer key

Compare your answers after you have finished Part 1.

1. On an ANSI-style sign, which signal word is reserved for hazards that will cause death or serious injury if not avoided?
   DANGER
2. Which background color is most commonly used on safety signs to indicate the location of first aid or general safety equipment?
   Green
3. You see a rectangular sign with a green background and white text that reads "FIRST AID STATION." What is this sign primarily communicating?
   The location of emergency medical or safety equipment
4. Which description matches a GHS hazard pictogram on a chemical label?
   A red diamond frame with a black symbol on a white background
5. At a loading dock, you see a large square-on-point placard on the side of a tanker truck with a four-digit UN number and a flame symbol. Which hazard communication system are you looking at?
   DOT transport placard
6. You see a solid red rectangular sign with a white fire extinguisher pictogram and no signal word. What is this sign telling you?
   The location of fire-fighting equipment
7. NFPA 704 diamonds are intended mainly for marking transport vehicles on public roads.
   False
8. All red workplace safety signs mean that a specific action is prohibited.
   False
9. A production line has a nip point where contact will almost certainly cause amputation if someone reaches in while the machine is running. Guards occasionally have to be removed for servicing. Which signal word is most appropriate for an ANSI-style sign mounted at that point?
   DANGER
10. A sign shows the standard emergency exit running figure symbol, with an arrow pointing to the right and text that reads "EXIT ROUTE THIS WAY." What does the arrow primarily tell you to do?
    Move toward the right to reach the emergency exit route
11. When you face a complex sign that mixes color, a pictogram, and text, what is the best first step to interpret it correctly as emphasized in the Safety Signs Identification Quiz guidance?
    Identify what sign system it belongs to and read the signal word/header
12. Under OSHA 29 CFR 1910.145, what is the primary purpose of accident prevention tags used on equipment or in work areas?
    To temporarily warn about specific hazardous conditions that are unexpected or not readily apparent
13. If a sign shows a pictogram of a person slipping and includes text that says "USE HANDRAIL ON STAIRS," the text is what tells you the required action.
    True
14. When a standardized signal word header is missing but the pictogram seems clear, you should ignore site procedures and act based only on what you think the symbol means.
    False
15. On a GHS-aligned label, the presence of any signal word such as DANGER or WARNING means the chemical has at least one classified hazard.
    True
16. A tank in your process area has a GHS label with the flame over circle pictogram and the word DANGER. Beside the tank, the wall-mounted NFPA 704 diamond shows a blue 2, red 0, yellow 3. Why is it unsafe to treat the NFPA numbers as if they are extra GHS classifications for the tank contents?
    Because NFPA 704 rates emergency response severity at the location, not the container’s GHS hazard classes
17. A process chemical can cause severe but reversible eye irritation and moderate respiratory discomfort if workers are repeatedly exposed without protection, but it is not life-threatening in normal use. Which ANSI signal word is generally most appropriate for a sign at the point of use reminding workers to wear goggles and a respirator?
    CAUTION
18. A doorway has a symbol-only "no entry" pictogram on the top panel and a supplemental panel below that reads "AUTHORIZED PERSONNEL ONLY BEYOND THIS POINT." You are walking past the doorway in a hallway. Where is the access boundary that the sign controls?
    Any work area on the same floor as the doorway
19. When you approach a complex ANSI-style safety sign with color, a signal word panel, a pictogram, and several lines of text, in what order should you process the information to decide what to do?
    Correct order: Identify the sign system using overall shape and border style → Read the signal word or header panel → Read the main message panel for hazard description → Read any action statements and boundary phrases → Check arrows, distances, or directions for where the rule applies
20. A tanker truck with a DOT flammable liquid placard is parked near a warehouse door that also has an NFPA 704 diamond and posted emergency contact information. You need a quick snapshot of the hazards you would face if you had to enter the warehouse to investigate an alarm. Which marking should you primarily use for that at-a-glance risk judgment?
    The NFPA 704 diamond posted at the warehouse door
21. You encounter a faded, homemade sign with a hand-drawn skull symbol near a chemical pump. The signal word is missing, and you cannot clearly read the rest of the text. What is the most appropriate action consistent with good safety sign practice?
    Stop work in that area, verify the hazard using site procedures, and report the sign for replacement
22. In ANSI-style safety signs, the signal word NOTICE is used for non-injury information such as procedures, property protection, or general instructions.
    True
23. OSHA's Hazard Communication Standard aligns workplace chemical labels and safety data sheets with the Globally Harmonized System (GHS).
    True
