Improving workplace health & safety through collaboration
Body
ANSI Z535 and the OSHA 1910.14 Specifications for Accident Prevention Safety Signs require the use of safety signs to indicate specific hazards that, without identification, may lead to accidental injury to workers and/or the public, or lead to property damage. Keep signs simple and concise, but also make sure they communicate sufficient information so that the message is clear. OSHA compliant safety labels should be designed to the same standards as safety signs. For example, they should use the same colors as signs. Be consistent in your design so that your labels look like your signs. Variations in design can result in confusion and result in more time needed to read and understand the label. Consistent design of labels and signs, the colors used, how safety symbols are used, and what the header looks like all help communicate critical information quickly.
Types & Meanings:
Danger signs :
Indicate an immediate hazard which, if not avoided, will result in death or serious injury. Danger signs should be limited to the most extreme situations and signify that special precautions are necessary. The heading “DANGER” is printed in white letters on a red background and is preceded by the safety alert symbol (an equilateral triangle surrounding an exclamation mark). The message should be printed in black or red letters on a white background, or white letters on a black background. Additional safety symbols may be included in the message area.
Warning signs:
Represent a hazard level between caution and danger. “Warning” indicates a hazardous situation which, if not avoided, could result in death or serious injury. The heading “WARNING” (preceded by the safety alert symbol) is written in black on an orange background. Additional wording and safety symbols are printed in black on the lower portion of the sign. Warning signs and labels can be any size, but it is appropriate for the sign to be noticed and easily read from a safe distance. They need to communicate the warning information before someone is in a dangerous area or acts in a dangerous manner.
Caution sign :
Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. Caution signs are used in areas where potential injury or equipment damage is possible, or to caution against unsafe practices. Caution signs should only be used if there is a risk of personal injury. The heading “CAUTION” is written in black letters on a yellow background and is preceded by the safety alert symbol. The message and safety symbols in the body of the sign are printed in black. Biological Hazard signs. According to OSHA §1910.145(e)(4), “The biological hazard warning shall be 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… presenting a risk or potential risk to the well-being of man.” The symbol design must conform to the design as shown in the “BIOHAZARD” sign and contain the word “Biohazard” or “Biological Hazard.” The biohazard symbol can be black, fluorescent orange, or orange-red color. Background color is optional as long as there is sufficient contrast for the biohazard symbol to be clearly defined. A biohazard can also be indicated on a danger or warning sign and may include the safety alert symbol.
Notice signs:
Provide general information that is important or relevant to a building, an area, a machine, or equipment. Notice signs address practices not related to personal injury. The heading “NOTICE” should be in white italic letters on a blue background. Notice signs should never include the safety alert symbol. The body of the sign is white, and the message is in blue or black lettering on a white background, or white lettering on a black background. Safety symbols can be printed in either blue or black. Notice signs can include information about procedures, operating instructions, maintenance information, rules, or directions. Notice signs are never used for personal injury hazards or warnings, but can be used to indicate possible equipment or property damage.
General Safety:
Signs are used to provide notices of general practice and rules relating to health, first aid, medical equipment, sanitation, housekeeping, and suggestions relative to general safety measures. Signs containing safety instructions or procedures should use heading “SAFETY INSTRUCTIONS” or “SAFETY PROCEDURES.” Where practical, use a more definitive heading, such as “SAFETY SHUTDOWN PROCEDURE.” Signs indicating the location of safety equipment should use a specific header such as “EYEWASH.” If multiple safety items are in the same location, simply use the header “SAFETY EQUIPMENT.” The message and safety symbols should be printed in green or black on a white background. The signs may also be printed in white on a green background. These signs should never include the safety alert symbol.
Fire Safety :
Signs are used to indicate the location of emergency fire fighting equipment. Unlike other signs, they do not require a header. The message and safety symbol are printed in red on a white background, or in white on a red background. Because these signs do not indicate a personal safety hazard, the safety alert symbol must not be used. Fire safety signs are not used to show the direction to fire equipment, but rather its immediate location .
Admittance signs:
Bridges all of the above categories. Admittance messages may be included on a sign with any header. You might decide to put “Unauthorized Personnel, Keep Out” on a danger, warning, caution, or notice sign. You may choose to include an admittance message on a general safety sign. The type of header and message content should be determined by the personal risk (if any) or consequences of entering the restricted area. The primary action statement should be simple, direct, and applicable to the hazard. Keep only essential hazard-related information on the sign. If necessary, consideration can be given to referring the viewer to another source for additional safety information or for permission to proceed. When information on consequence, avoidance, or type of hazard is readily inferred, this information may be omitted from the message panel.
Safety Symbols :
Signs and labels may include safety symbols, often called pictograms pictorials, or glyphs. Safety symbols can portray required actions, consequences, explicit direction, or the effects of interaction with certain chemicals, machines, and other hazards. Signs and labels may include more than one pictorial to show a sequence of events for one hazard. Safety symbols should be consistent, readable, and easily understood. They usually consist of a black image on a white background.
Surround Shapes - You may consider using a surround shape. However, a surround shape will decrease the available space for a symbol. Surround shapes should not be used if they detract from the major message.
HAZARD ALERTING - You can use this surround shape to highlight a hazardous condition. The symbol should be drawn within a black equilateral triangle and can include a yellow background.
MANDATORY ACTION - This type of symbol conveys actions that must be taken to avoid hazards. This symbol consists of a white image within a solid blue or black circle. PROHIBITION - For actions that should not be taken, this surround shape is required. It consists of a red or black circle with a diagonal slash at 45° from the upper-left to the lower-right.
INFORMATION - The square (or rectangular) surround shape is typically used to convey equipment location, places of exit, and permitted actions.
