Foreword
GB/T 1251 is divided into three parts.
--- Part 1. Ergonomics danger signals - Auditory danger signals in public places and work areas;
--- Part 2. Ergonomics - Visual danger signals - General requirements, design and testing;
--- Part 3. Visual Ergonomics danger signal system and information.
This part of GB/T 1251 Part 1.
This part identical with ISO 7731.2003 "Ergonomics public places and work areas - Auditory danger signal danger signal"
(In English), and in accordance with ISO 7731.2003 Translation drafted.
This Part replaces GB 1251.1-1989 "auditory danger signal danger signal in the workplace." And GB 1251.1-1989 phase

Introduction
This section provides guidelines for the recognition of auditory signals danger, especially in the case of high background noise. This section contains a variety of
Auditory danger signals, text by "danger signal" to refer to the emergency signals and warning signals (see Table 1).
Also it relates to the following national standards Auditory danger signals.
--- GB/T 12800 in the emergency evacuation signal;
--- GB/T 1251.3 in danger auditory and visual signals.
Table 1 shows the various types of danger signals and reaction when they hear these signals need to make.
Should be noted, GB/T 1251.3 danger signal type in more detail.
Table 1 Danger Signal Type
The reaction danger signal type need to make
Auditory emergency evacuation signal immediately leave the danger zone
Auditory emergency signal for urgent action to seek aid
Auditory warning signals or prepared to take preventive measures
Design appropriate danger signals can effectively prompt attention to hazards or hazardous environments (even in the case of wearing ear protectors), and will not
Cause panic.

1 Scope
This section GB/T 1251 specifies the signal reception areas in public places and work areas, and physical danger signal design principles,
Ergonomic requirements and corresponding test methods, and gives the signal design guidelines. This section can also be used in other appropriate environments.
Should pay attention to the emergency audible signal, auditory emergency evacuation signal and an auditory warning signal differences and connections between. Emergency evacuation signal
GB/T 12800 in the appropriate elaboration.
This section does not apply to verbal danger warnings (for example, shouting, speaker, broadcast, etc.). Danger signals corresponding speech in the ISO 9921
Elaboration.
Specific regulations, public disaster and public transport and other aspects of the present without some restrictions.
2 Normative references
The following documents contain provisions which, through reference to GB/T 1251 to the present, constitute provisions of this section. For dated references,
All subsequent amendments (excluding corrections) or revisions do not apply to this section, however, encourage an agreement under this section
Parties to study the latest versions of these documents. For undated reference documents, the latest versions apply to this section.

3 Terms, definitions and symbols
The following terms and definitions apply to this section.
Note. The symbols defined in Appendix A.
3.1
Sound signal reception in all areas, non-dangerous signal generator.
3.2
According to the urgency of the danger and possible injury to people caused by auditory danger signal into auditory emergency signal, auditory emergency evacuation
Three warning signals and an audible signal.
3.2.1
Flag signal danger began. If necessary, further comprising a sustained and marked the termination signal danger.
3.2.2
Flag has begun or is taking place and is likely to cause injury to signal an emergency, this signal indicates that people in the manner determined
Immediately leave the danger zone.
Note. GB/T 12800 mainly describes the emergency evacuation audible signal.
3.2.3
Flag imminent or is occurring, we need to take appropriate measures to eliminate or control the risk of danger signals.
NOTE. Warning auditory signals can also provide people to take action or measure information.
