Red Steady indicates which level has been exceeded?

• A. Exceeded the alert level
• B. Exceeded the critical level
• C. Exceeded the warning level
• D. Exceeded the alarm level

Answer: (D)

Red steady means you’ve moved into the alarm state. In most safety indicators and gas detectors, colors map to hazard levels: normal is green, lower-severity notices use amber or yellow, and the red signal represents an alarm condition. A steady red indicates the gas concentration has crossed the alarm setpoint and remains above it for the required response time, signalling immediate action is needed (evacuate, isolate the area, follow emergency procedures). Lower levels like alert or warning correspond to less severe indicators (typically yellow or orange) and don’t demand the same urgent response. The term “alarm” is the standard designation for this highest-priority condition.
