3 Role of safety signs and general requirements

3.1 Reduce the risk by design principles.

Security throughout the machinery and equipment design, manufacture, operation, instructions and inspection process. Without lowering product features case, by the following measures to sufficiently reduce or eliminate the risk.

--- Select the appropriate structure and composition of the material, to eliminate or reduce the risk;

--- Reducing the need for operator intervention in the danger zone, to limit the danger it faces;

--- By design hazard can not be eliminated or sufficiently limited, it should be guards or other safety devices in order to avoid danger.

Despite a suitable design to avoid danger, but the risk may still exist legacy, safety signs are used to alert operators and the presence of other persons about residual risk.

3.2 Role of safety signs.

--- A reminder of the presence or potential danger;

--- Indicate danger;

--- Description of the nature of risk;

--- Illustrate the dangers of possible consequences of injury;

--- Instruct people how to avoid danger.

3.3 Safety signs set principles.

--- Can be eye-catching and effective reminder of the presence or potential danger;

--- Can accurately visualize dangerous nature;

--- Clear indication of how people can avoid danger.

3.4 in accordance with the mining machinery and parts may produce dangerous levels, should the appropriate safety signs on the device and instructions for use in the preparation Book. Safety signs should be set on the device in a hazardous location or preventing dangerous scope of monitoring to ensure that no obstacles impeding the safe fixed VIZ normal flag.

3.5 Safety signs shall be securely connected, legible, and equipment have significantly different, their life should comply with GB 18209.2 flag throughout the machine Mechanical life of the provisions.

3.6 In order to avoid confusion at a position involving dangerous should prevent the excessive use of safety signs. Excessive use of safety signs will reduce its effect.

3.7 can be used alone as an illustration of safety signs, as text messages may not be recognized (as a result of language differences or educational process Degrees), use a text message on safety signs should be used in conjunction with other non-text information to indicate danger.

3.8 should give full consideration to the use of safety signs and other hazards caused by the possibility of occurrence.

3.9 Use of explosion-proof equipment safety signs should comply with the relevant standards.

4 in the form of safety signs

4.1 Safety signs surrounded by a border of two or more rectangular flag region.

4.2 Safety Signs arrangement of rectangular flag area are arranged laterally and longitudinally arranged in two ways, the selected arrangement to transfer information Effectiveness of available area of safety signs, which the locale is determined.

Rectangular flag area 4.3 Safety signs include the following three types.

--- Symbol area;

--- Icon zone;

--- Text area.

4.4 Composition of the following standard safety signs four forms.

--- Rune formula. Symbol area, text area;

--- Third District formula. Symbol area, graphic area, text area;

--- Photo type. icon area, text area;

--- Two drawings. two graphic area.

4.5 Rune safety signs shown in Figure 1. Symbol region including safety alert symbol and a sign of the degree of danger represented three kinds of words (note, warning, danger Insurance) one. Text area contains dangerous describe, explain the consequences of risk and indicates how to avoid the dangers of text messages.

Figure 1 Rune safety signs

4.6 three-zone safety signs shown in Figure 2. Symbol zone includes three kinds of safety alert symbol and flag word (note, warning, danger) one. Icon Area contains description dangerous hazard pictorials, or in some cases to describe a combination of danger and avoid dangerous shown. Text Area contains dangerous Description insurance, risk consequences, and explain how to avoid the danger of indicating a text message.

2 three-zone safety signs

4.7 Teletext safety signs shown in Figure 3. Graphic area includes the security alert triangle surrounded by the icon or description of the risk of individual security Alert symbol. Text area contains dangerous describe, explain the consequences of risk and indicates how to avoid the dangers of text messages.

Icon or a separate safety alert symbol. The second zone is shown illustrating avoid dangerous areas, to avoid the danger of containing chart area.

4.9 In some cases, the above standard form appropriate changes, and shall comply with the provisions of Chapter 3.

5 Symbol Area

5.1 Symbols area of safety signs and symbols contained in one of three flags word security alert.

5.2 safety alert symbol on one of the signs safety signs contained the word used in Figure 5, it contains three kinds of safety standards, one of the word mark Chi should use the safety alert symbol.

5.3 Safety signs according to the severity of the respective dangerous situations by using the flag word classification.

Three kinds of flag word. Danger, Warning and Caution. Flag teleprompter observer dangerous and hazardous corresponding severity.

Three kinds of flag word dedicated to the risk of injury, according to estimates by the consequences of the possibility of danger and by the danger that may arise to Selected a sign words.

--- Represents danger, if not avoid dangerous consequences will result in death or serious injury. By the flag word "danger" tag security the marking shall apply only to the presence of a small number of the most serious risk situations;

--- WARNING indicates, if not avoid, potentially dangerous consequences that may result in death or serious injury. By the flag word "warning" danger mark Insurance, represents the risk of injury and death than the degree symbol word "dangerous" level of risk is lower mark;

--- Notice indicates that, if not avoid, potentially dangerous consequences that may result in a lower or moderate injury. "CAUTION" may also be used to provide Beware shows may lead to personal injury case relating to unsafe operation.

5.4 symbols areas, safety alert symbol arranged on the left and the word mark are arranged on the right. When the flag word required when there are two languages, two languages Flag word is generally arranged up and down.

Figure 5 contains a safety alert symbol a sign word

6 Illustrates the area

6.1 Safety signs graphic area by a graphical depiction of danger or a risk of circumvention or graphic symbols only by a security guard. Map Illustration shows danger zone should be designed to meet the requirements of GB 25517.2.

6.2 illustrates for safety signs in two basic forms. description hazard pictorials and avoid dangerous icon.

--- Description hazardous icon. Description of hazardous figurative illustration, generally contain not avoid dangerous consequences will result;

--- Avoid danger icon. Indicates how to avoid dangerous figurative description.

6.3 Description hazard pictorials should clearly identify the hazard, and described the potential consequences contrary to the instructions will result. Avoid danger should be clearly shown Identify people when faced with the risk of circumvention is necessary to take action.

Description illustrates the danger is most commonly used to avoid the danger icon can be used to supplement or replace text message icon. If necessary, allow these two Illustrated combination of an icon.

Unless it can clearly show the relationship between the risk of multiple, otherwise in general should avoid using a diagram to include multiple hazards.

6.4 on a graphic or two-schema safety signs describing the danger illustrated by a triangle surrounded by security alert to indicate that the symbol for safety Mark. Security alert triangle shown in Figure 6.

6 security alert triangle

6.5 If not used within the security alert triangle described hazard pictorials, put an exclamation point placed inside the triangle formed shown in Figure 7 Basic safety alert symbol.

7 Basic safety alert symbol

7 text area

Text area contains safety signs 7.1 describes the danger described later suffered dangerous potential consequences as well as instructions on how to avoid dangerous text Information, which may be a separate, can also be combined with the graphic area.

7.2 If a sufficient description of hazard pictorials depict the dangers and possible consequences of the above could be deleted from the text area or two item. If the icon is sufficient to avoid dangerous describe how to avoid danger, the content can be deleted from the text area. If you do not use the icon text area We must express all the three elements. It should be as little as possible the number of rows concisely written text messages.
