Refresher Training. 3.1 Retraining will be provided for all authorized and affected employees whenever there is a change in their job assignments, a change in machines, equipment or processes that present new color codes, signs, or tags, or when there is an accident resulting because of a color code, sign, or tag this is defaced or inaccurate. 3.2 Additional retraining will also be conducted whenever a periodic inspection reveals, or whenever this employer has reason to believe, that there are deviations from or inadequacies in the employee's knowledge or use of the color codes, signs, or tags. 3.3 The retraining will reestablish employee proficiency and introduce new or revised color codes, signs or tags as necessary.
3.4 Certification. This employer will certify that employee training has been accomplished and is being kept up to date. The certification will contain each employee's name and dates of training. Each employee's training records will be updated to reflect additional training. 4. Color identification. 4.1 Red. Red will be the basic color for the identification of: 4.1.1 Fire protection equipment and apparatus. 4.1.2 Danger. Safety cans or other portable containers of flammable liquids having a flash point at or below 80 F, table containers of flammable liquids (open cup tester), excluding shipping containers, will be painted red with some additional clearly visible identification either in the form of a yellow band around the can or the name of the contents conspicuously stenciled or painted on the can in yellow. Red lights will be provided at barricades and at temporary obstructions, as specified in ANSI Safety Code for Building Construction, A10.2 1944. Danger signs will be painted red. 4.1.3 Stop. Emergency stop bars on hazardous machines such as rubber mills, wire blocks, flat work ironers, etc., will be red. Stop buttons or electrical switches which letters or other markings appear, used for emergency stopping of machinery will be red. 4.2 Yellow. Yellow will be the basic color for designating caution and for marking physical hazards such as: Striking against, stumbling, falling, tripping, and "caught in between." 5. Accident prevention signs. The following specifications apply to the design, application, and use of signs or symbols intended to indicate and, insofar as possible, to define specific hazards of a nature such that failure to designate them may lead to accidental injury to our workers or the public, or both, or to property damage. The following specifications are intended to cover all safety signs utilized by this company except those designed for streets, highways, railroads, and marine regulations. These specifications do not apply to plant bulletin boards or to safety posters. 5.1 New and replaced signs. All new signs and replacements of old signs (on or after August 31, 1971), used by this company will be in accordance with these specifications. 5.2 Classification of signs according to use 5.2.1 Danger signs. 5.2.1.2 There will be no variation in the type of design of signs posted to warn of specific dangers and radiation hazards.
5.2.1.3 All employees will be instructed that danger signs indicate immediate danger and that special precautions are necessary. 5.2.2 Caution signs. 5.2.2.1 Caution signs will be used only to warn against potential hazards or to caution against unsafe practices. 5.2.2.2 All employees will be instructed that caution signs indicate a possible hazard against which proper precaution should be taken. 5.2.3 Safety instruction signs. Safety instruction signs will be used where there is a need for general instructions and suggestions relative to safety measures. 5.3 Sign design. Design features. All signs procured or used by this company will be furnished with rounded or blunt corners and will be free from sharp edges, burrs, splinters, or other sharp projections. The ends or heads of bolts or other fastening devices will be located in such a way that they do not constitute a hazard. 5.3.1 Danger signs. 5.3.1.1 The colors red, black, and white will be those of opaque glossy samples (as specified in the "Fundamental Specification of Safety Colors for CIE Standard Source "C", American National Standard Z53.1 1967). Figure Example, Danger Sign 5.3.2 Caution signs. 5.3.2.1 Standard color of the background will be yellow; and the panel, black with yellow letters. Any letters used against the yellow background will be black. The colors will be those of opaque glossy samples as specified in Table 1 of American National Standard Z53.1 1967. Figure Example, Caution Sign 5.3.3 Safety instruction signs. Standard color of the background will be white; and the panel, green with white letters. Any letters used against the white background will be black. The colors will be those of opaque glossy samples as specified in Table 1 of American National Standard, Z53.1 1967. Figure Example, Safety Instruction Sign 5.3.4 Slow moving vehicle emblem. This emblem consists of a fluorescent yellow orange triangle with a dark red reflective border. The yellow orange fluorescent triangle
is a highly visible color for daylight exposure. The reflective border defines the shape of the fluorescent color in daylight and creates a hollow red triangle in the path of motor vehicle headlights at night. The emblem is intended as a unique identification for, and it will be used only on, vehicles which by design move slowly (25 m.p.h. or less) on the public roads. The emblem is not a clearance marker for wide machinery nor is it intended to replace required lighting or marking of slow moving vehicles. Neither the color film pattern and its dimensions nor the backing will be altered to permit use of advertising or other markings. The material, location, mounting, etc., of the emblem will be in accordance with the American Society of Agricultural Engineers Emblem for Identifying Slow Moving Vehicles, ASAE R276, 1967, or ASAE S276.2 (ANSI B114.1 1971). Figure Example, Slow Moving Vehicle Emblem 5.3.5 Biological hazard signs. The biological hazard warning is used to signify the actual or potential presence of a biohazard and to identify equipment, containers, rooms, materials, experimental animals, or combinations thereof, which contain, or are contaminated with, viable hazardous agents. It this respect the term "biological hazard," or "biohazard," includes only those infectious agents presenting a risk or potential risk to the well being of humans. 5.4 Sign wordings. Figure Example, Biological Hazard Sign 5.4.1 Nature of wording. The wording of any sign used by this company will be easily read and concise. All signs will contain sufficient information to be easily understood. The wording will be formed to make a positive, rather than negative suggestion and will be accurate in fact. 6. Accident prevention tags. The following specifications apply to the design, application, and use of tags intended to indicate and, insofar as possible, to identify hazardous conditions and provide a message to our employees with respect to hazardous conditions as set forth in this Standard Practice Instruction, or to meet the specific tagging requirements of other OSHA standards such as the Control of Hazardous Energy Standard (Lock Out Tag Out). 6.1 Intended use. Tags will be used as a means to prevent accidental injury or illness to employees who are exposed to hazardous or potentially hazardous conditions, equipment or operations which are out of the ordinary, unexpected or not readily apparent. Tags will be used until such time as the identified hazard is eliminated or the hazardous operation is completed. Tags need not be used where signs, guarding or other positive means of protection are being used. 6.2 General tag criteria. All required tags will meet the following criteria: 6.2.1 Tags will contain a signal word and a major message.
6.2.1.1 The signal word will be either "Danger," "Caution," or "Biological Hazard," "BIOHAZARD," or the biological hazard symbol. 6.2.1.2 The major message will indicate the specific hazardous condition or the instruction to be communicated to the employee. 6.2.1.3 The signal word will be readable at a minimum distance of five feet (1.52 m) or such greater distance as warranted by the hazard. written text or both. 6.2.1.4 The tag's major message will be presented in either pictographs, 6.2.1.5 The signal word and the major message will be understandable to all employees who may be exposed to the identified hazard. 6.2.1.6 All employees will be informed as to the meaning of the various tags used throughout the workplace and what special precautions are necessary. 6.2.1.7 Tags will be affixed as close as safely possible to their respective hazards by a positive means such as string, wire, or adhesive that prevents their loss or unintentional removal. 6.3 Types of tags. 6.3.1 Danger tags. Danger tags will be used in major hazard situations where an immediate hazard presents a threat of death or serious injury to employees. Danger tags will be used only in these situations. Recommended Color Coding "DANGER" Red, or predominantly red, with lettering or symbols in a contrasting color. 6.3.2 Caution tags. Caution tags will be used in minor hazard situations where a non immediate or potential hazard or unsafe practice presents a lesser threat of employee injury. Caution tags will be used only in these situations. Recommended Color Coding "CAUTION" Yellow, or predominantly yellow, with lettering or symbols in a contrasting color. 6.3.3 Warning tags. Warning tags may be used to represent a hazard level between "Caution" and "Danger," instead of the required "Caution" tag, provided that they have a signal word of "Warning," and an appropriate major message.
Recommended Color Coding "WARNING" Orange, or predominantly orange, with lettering or symbols in a contrasting color. 6.3.4 Biological hazard tags. 6.3.4.1 Biological hazard tags will be used to identify the actual or potential presence of a biological hazard and to identify equipment, containers, rooms, experimental animals, or combinations thereof, that contain or are contaminated with hazardous biological agents. Recommended Color Coding "BIOLOGICAL HAZARD" Fluorescent orange or orange red, or predominantly so, with lettering or symbols in a contrasting color. 6.3.5 Other tags. Other tags may be used in addition to those indicated in this Standard Practice Instruction or in other situations where tags are required, provided that they do not detract from the impact or visibility of the signal word and major message of any required tag. 7. Definitions used in this Standard Practice Instruction. Biological hazard or BIOHAZARD means those infectious agents presenting a risk of death, injury or illness to employees. Major message means that portion of a tag's inscription that is more specific than the signal word and that indicates the specific hazardous condition or the instruction to be communicated to the employee. Examples include: "High Voltage," "Close Clearance," "Do Not Start," or "Do Not Use" or a corresponding pictograph used with a written text or alone. Pictograph means a pictorial representation used to identify a hazardous condition or to convey a safety instruction. Sign refers to a surface on prepared for the warning of, or safety instructions of, industrial workers or members of the public who may be exposed to hazards. Excluded from this definition, however, are news releases, displays commonly known as safety posters, and bulletins used for employee education. Signal word means that portion of a tag's inscription that contains the word or words that are intended to capture the employee's immediate attention. Tag means a device usually made of card, paper, pasteboard, plastic or other material used to identify a hazardous condition.
