Mining machinery - Safety signs - Part 2: Symbols for hazard pictorial
1 Scope
This part of GB 25517 outlines the principles and guidelines for the design of symbols for hazard pictorials of safety signs on mining machinery (hereinafter referred to as “hazard pictorials”), and stipulates the drawing of the hazard pictorial elements.
This part is applicable to the design of hazard pictorials in the pictorial panel of safety signs on mining machinery.
2 Normative references
The following normative documents contain provisions which, through reference in this part of GB 25517, constitute provisions of this part. For dated references, subsequent amendments (excluding corrections) to, or revisions of, any of these publications do not apply to this part. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.
GB 25517.1-2010 Mining machinery - Safety signs - Part 1: General principles
3 Design guidelines
3.1 Classification
Hazard pictorials are classified into two types: hazard description pictorials and hazard avoidance pictorials. Hazard description pictorials are representational description of the hazards and describe the consequences if one fails to avoid the hazard; hazard avoidance pictorials are representational description used to instruct persons about how to avoid hazards.
3.2 Dimensions and colors
3.2.1 Hazard pictorials shall meet the requirements for dimensions of safety signs specified in GB 25517.1-2010. Hazard pictorials used in instruction manuals may be sized according to the actual situation, but shall be legible enough.
3.2.2 If hazard pictorials are used for pictorial-and-text or two-pictorial safety signs, the hazard description pictorial shall be properly sized to be enclosed by the safety alert triangle.
3.2.3 Hazard pictorials used in instruction manuals may be colored according to the actual situation, but this color shall make hazard pictorials legible enough.
3.3 Principles for graphic design of hazard pictorials
3.3.1 A solid graphical representation shall be used to represent human body elements or the full human figure. An outline representation may be used when depicting a person whose presence is necessary to complete the pictorial but who is not directly involved with the hazard.
3.3.2 Representational pictorials shall be used for hazard pictorials, and abstract symbols should be avoided as much as possible.
3.3.3 The view (generally front or side) that is most easily recognized shall be used to describe the main hazard objects in the hazard pictorials.
3.3.4 Simplified solid graphics shall be used to represent the hazardous machine elements. Outline graphics of complete machines or of substantial portions of machines to locate hazardous areas or machine elements in context shall be used for easy recognition of the human figure.
