Use of Color Coding

When using safety color-codes to mark physical hazards, OSHA requires that  

Guarding enhancement through the use of color helps provide awareness for a particular hazard. Color alone, however, will not prevent an injury. The employee must first recognize the color and make a decision in his/her mind as to what hazard it represents. The color could be on a fixed barrier or the color could be generated from a light. Color and lights to highlight hazards help make the warehouse safer. 

Flashing amber lights on powered equipment help warn others of its approach. Where the aisles are busy and stacked with product a worker could easily walk into the path of a vehicle. Of course, horns and back up alarms on powered equipment offers additional safeguarding. The audio and visual effects of alarms and lights are intended to alert employees and visitors to the movement of powered equipment. Numerous injuries have been prevented because a conscientious employer took time to go beyond an OSHA regulation. OSHA currently does not 

It should be noted that there is no research to validate the 100 percent effectiveness of alarms and flashing lights. Back up alarms are usually reserved only for counter-balanced forklifts. 

The use of yellow or a yellow/black striped combination of paint can be very effective in highlighting physical hazards. Consider painting edges of docks, perimeters of dock plates, barrier posts, walkway lines, machine guards, handrailing, edges of stairs, crane/hoist blocks, and comers of roll-up doors. In addition, red and white paint can be used to highlight fire protection equipment.

The use of color-differentiation is favored whereas the use of color coding is controversial because of the limited number of colors, the prevalence of color blindness in the general population, and inappropriate reliance on color in lieu of reading the label. 

Make labels brief, bold, simple, and clear repeat or place same labels on various parts of a product make use of color coding, failsafe innovations, and other attention-demanding devices... 

The above-mentioned surfaces are not only u.sed for imaging the bulkiness and shape of molecules, but also serve as screens for the visualization of higher dimensional information. A popular method of displaying scalar values on molecular surfaces is achieved by the use of color codes. Such a representation allows an immediate identification of important molecular regions. This is demonstrated in Figures 17-23 with different examples. 

The EU directive includes a list of colorants (coded as E numbers, from E 100 to E 180) suitable for use as food additives and specifies limits of impurities. For details about their codes, sources, and properties see Table 7.2.1. An update of EU legislation on food-related issues was published recently. In addition to the numbered E colorants, other new natural colors for use in the future as natural colorants are under examination (see positions 25 through 34 in Table 7.2.1). ... 

Respirators are sometimes desirable or required when performing certain tasks in the chemical analysis laboratory. There is a standardized color code system used by all manufacturers for the specification and selection of the cartridges and filters that are used with respirators. The following table provides guidance in the selection of the proper cartridge using the color code. 

It is advisable to use a color-coded labeling system to keep track of the test stages. In our case, a yellow spot was added after successful heat cycling with test software loaded, and a green spot half covering the yellow spot was added once the validated software had been loaded and the board tested successfully no device could be shipped unless both spots are present. The manufacturer will be expected to supply a certificate of conformity for the devices produced and packed with each batch. 

The molecular surface concept is not only useful for a representation of the bulkiness and the shape of molecules. These surfaces can also be used as screens for the visualization of many properties by means of color coding techniques. Color coding is a popular means of displaying scalar information on a surface. " " Every three-dimensional scalar or vector field that may be generated on the basis of the position of atomic or molecular fragments can be visualized by color coding on a given surface. 

Both the GET and POST methods accept KEGG identifiers as input and colors in hexadecimal code (hex code) format for fore- and background color. The usage of hex code for colors allows use of color gradients for mapping of differential gene expression or different metabolite concentrations. 

Colorants, other than titanium dioxide, are rarely used in plastic containers however, the use of colorants is required for the cap. The American Academy of Ophthalmology (AAO) recommended to the FDA that a uniform color coding system be established for the caps and labels of all topical ocular medications. Industry new drug applicants are required to either follow this system or provide an adequate justification for any deviations from the system. The AAO color codes, as revised and approved by the AAO Board of Trustees in June 1996, are shown in Table 4. The FDA and AAO have extended the cap color scheme to differentiate different classes of newer Rx drugs for the benefit of the patient who may be using more than one product. The intent is to help prevent errors in medication and improve patient compliance. It is important for the pharmacist to explain this color coding to the patient and/or caregiver since it can be defeated if the cap is not returned to the proper container after each use.

The most widely referenced standard for identification by means of color coding is EIAyTIA-598, Color Coding of Fiber Optic Cables. This document outlines the standard color coding and identification sequence used for fiber and fiber units, such as buffer tubes or binding threads. The twelve primary colors used and their sequence are listed in Table 9.10. 

An objective of the risk guidance tool is to develop a situational awareness of the potential for a loss-producing event. For a visual representation of the risk assessment, the risk guidance tool uses a color code. An example of the use of color is found in The US Navy s Operational Risk Management (ORM) Fundamentals ...
