- Scope
- In order to reduce the risk of misinterpreting visual and auditory distress signals, this part of GB/T 1251 specifies a system of distress and information signals with different levels of urgency. This part is applicable to all kinds of dangerous signals and information signals, including signals that need to be clearly detected and distinguished in accordance with 5.3 of GB/T 15706.2-2007, and signals that need to be clearly detected and distinguished under other requirements or working conditions; this part Also applies to all signals with an urgency ranging from "Extreme Urgent" to "All Clear". When an audio signal is supplemented by a visual signal, the signal characteristics of both shall be specified. This section does not apply to areas where specific standards or other mandatory practices (international or national) have been adopted, especially fire alarms, medical alarms, alarms used in public transport, navigation signals and for special field activities (for example, military activity). However, for consistency, this section should be referred to when adopting new signals. For auditory information signals classified according to urgency, the signal characteristic system specified in this part can be used as a guide for the design of the signal language. In order to identify the signal reliably and quickly, this standard specifies the specific characteristics of the signal. Certain classes of signals allow changes in signal characteristics, such as control and warning signals for employees with specific training in the workplace. For visual signals, the meaning of existing safety colors is not affected by this standard. According to different needs, timing patterns and color alternation can be used as supplementary meanings of visual signals. Color alternation is used only in rare cases.
