What do you need to know about Safety Signs:

Environmental & facility safety signs are usually larger because they are observed at further distances. These signs usually contain lesser amounts of information for visual clarity at a distance. Signs should be placed in a clearly visible location and should be protected from damage and obliteration.

  • When safety signs are distinguished by their color code (ANSI Z535.2) they become useful tools to help protect the health and safety of personnel at the workplace.
  • Safety signs are a supplement to, and NOT a substitute for, the required protective measures for eliminating or reducing the hazards in the workplace.
  • Reading and understanding safety signs displayed on machinery or around your facility will help minimize the possibility of accidents and increase hazard awareness.

Safety Signs Objectives:

  • The objective of safety signs is to draw attention rapidly and precisely to objects and situations capable of causing specific injuries or accidents.
  • To alert or warn personnel about workplace hazards of which they may not be aware of.
  • To restrict access to areas that present dangerous conditions.
  • To inform people of safety requirements.
  • Provide general information and directions.
  • Remind employees where PPE equipment must be worn.
  • Show where emergency equipment or exits are located.
  • Indicate where certain actions are prohibited.

Sign Message Panel Content

ANSI Z535.2-2007 recommends the combination of upper and lower case sans serif text. Upper case only lettering may be used for short messages or emphasis of individual words.
  • Use Direct Statements: Safety signs are intended to communicate information quickly enough to allow a person to understand it and take appropriate actions to avoid the hazard. Reaction times can be reduced by using the simplest and most direct statements possible.
  • Use Action Statements: These are instructions of how to avoid hazards. The statement should be accurate, simple, direct and relevant to the hazard.
  • Hazard Description: Identifies the specific hazard with clear and simple language.
  • Consequence Statement: Use clear, accurate and simple language to warn persons of potential consequences if the warning is ignored.
  • Emergency Information: A telephone number or other contact information should go on sign after the Action, Hazard description and consequences statements.

Posting Safety Signs:

  • Safety signs in the workplace should be mounted for optimum viewing.
  • Signs should be placed in a manner so that they are legible, non-distracting, and non-hazardous in themselves.
  • Signs must be conspicuously posted for review by workers or any personnel approaching the hazardous area.
  • Posting safety signs in multiple languages will help ensure all of your employees are aware of the hazards that may be present.
  • Where practical place signs approximately every 40 feet.
  • In fenced areas, sign posting is only required at access points.
  • Placing too many sign, too close together should be avoided.
  • The quantity and placement of signs will depend on the extent of the hazards or the zone to be covered.
  • Whenever possible use safety symbols that are simple and easy to learn and recognize.
  • If safety symbols are being used they must be as simple as possible and should contain only essential details.

Safety Sign Recommended Viewing Distances

ANSI Z535-2007 standard uses a ratio of 25 ft of viewing distance per inch of text for Favorable Reading Conditions, and a ratio of 12 ft of viewing distance per inch of text for Unfavorable Reading Conditions. Determining the safe viewing distance of a sign depends upon many factors: lighting, background, type font and visual acuity. Other factors to consider in determining sign size include: the complexity of the message, the reaction time necessary and the angle the sign will be seen from. In many situations it is better to use multiple, smaller signs that are strategically positioned than one large sign. Many times letter size may need to be larger than the values shown on the graphic for a variety of reasons:
  • To make the sign more noticeable from other information displayed in the area.
  • To enable legibility under low light, or other poor viewing conditions.
  • To alert persons sooner than the minimum safe viewing distance.
  • To convey special importance for portions of the message.
  • To improve legibility for persons who have vision problems with small text.
