At iGraphics, we understand that prominent, easy to understand Safety Labels for your products are key to operating a safe, successful business. That’s why we’ve created a user-friendly guide to help you design your own. Read on for detailed instructions.
How to Design Safety Labels:
Printed Image: Your printed image is sealed between 2 layers of polyester or vinyl. Polyester and vinyl offer superior UV, chemical, abrasion and temperature resistance. The image is screen or digital printed using UV resistant inks.
Adhesive: Use aggressive solvent based acrylic adhesive with excellent adhesion properties on a broad base of application substrates such as Stainless Steel, Acrylic, Glass, Coated Metals and Plastics.
Safety Labels Compliance
- Most Machinery Safety Labels comply with ANSI Z535.4 2002 & 2007
- Some Machinery Safety Labels comply with ISO 3864-2 2002
- Some specific Safety Labels comply with CEMA
- Arch Flash Labels comply with NFPA 70E
Selecting the Right Safety Header
Hazard Classification: The first element to consider when designing or selecting a product Safety Label is to determine the likelihood and severity of a potential injury if a person does not follow the instructions contained on the safety label or sign.
There are four Signal Words or Hazard Classifications used in the design of an ANSI Z535.4 2007 compliant safety label: “DANGER,” “WARNING,”“CAUTION” and “NOTICE”
Safety Label Format
Message Panel: The message panel of any new ANSI Z535.4 2007 compliant sign or label must contain:
• Identification of the hazard,
• Identification of a means to avoid the hazard,
• And the consequences of not avoiding the hazard.
The order that the information appears in the message panel is flexible and should be determined by logical factors related to avoiding an injury, such as:
• The target audiences knowledge of the hazard,
• And the reaction time to avoid the hazard.
In addition, when formatting the message panel we recommend the following practices:
1. Use headline style text
2. Use active voice statements
3. Avoid prepositional phrases
4. Use left justification of the text except on one line messages
5. Use upper and lower case letters
Use of Safety Symbols
ANSI Z535.4 2002 encourages the use of safety symbols that communicate a comparable message to the worded message on the sign or label.
The safety symbol when selected properly, should identify:
• The hazard,
• Identify a means of avoiding the hazard,
• Or identify the consequences of not avoiding the hazard. The safety symbol should clarify or reinforce the worded message on the label.
There are four types of safety symbols used on ANSI Z535.4 2002 compliant product safety labels. When using safety symbols to comply with ANSI, the symbol can be black on a white background, other colors may be used, like safety red for fire related symbols, and so on.
To comply with both ANSI Z535.4 and ISO 3864, then the following applies, ISO 3864 2002 standards required that all of the safety symbols used on international product safety labels be within a surround shape, yellow equilateral triangle with black inner border for hazard alerting symbols, blue circle for mandatory actions, and red circle with 45° degree slash for prohibition symbols. ANSI Z535.4 2002 does not require the use of a yellow equilateral triangle or the mandatory surround shape but, it does recognize it and permits their use.
Hazard Alert Symbols
Hazard Alerting: This type of safety symbol conveys information primarily related to the nature of hazards. Like, hazard description, how to avoid the hazard and sometimes the consequences of not avoiding the hazard.
If a surround shape is desired, the hazard alerting symbol should be drawn within a yellow equilateral triangle. The yellow equilateral triangle is required on safety alert symbols used on ISO compliant product safety labels.
Prohibition Symbols: This type of safety symbol conveys actions that should not be taken. This symbol consists of a red circular band with a 45° diagonal red band from upper left to lower right. The symbol contains a black image within the red band on a white background. Prohibition symbols are mandatory for use on ISO compliant product safety labels. The image below shows some examples from the many that can be used on a safety label
Mandatory Action Symbols: This type of safety symbol conveys actions that should be taken to avoid hazards. If a surround shape is desired, the symbol consist of a white image within a solid blue or black circular surround shape. The blue surround shape is required on ISO compliant product safety labels that contain mandatory action symbols. The image below shows some examples from our Safety Symbol Database.
Information Symbols: This type of safety symbol is generally used on ANSI Z535.2 Environmental Safety or Fire Safety Signs, to convey equipment location, permitted actions and fire equipment location.

Safety Label: Letter Size Legibility
Determining the safe viewing distance of a label depends upon many factors, including
• Lighting, background, letter type and visual acuity.
Other factors to consider in determining label size, include:
• The complexity of the message, the reaction time necessary, and the angle the label will be seen from. In many situations it is better to use multiple labels that are strategically positioned instead of one large one.
Many times letter size may need to be larger than the values shown on the graphic for a variety of reasons:
1. To make the label more noticeable from other information displayed in the area
2. To enable legibility under low light, or other poor viewing conditions
3. To alert persons sooner than the minimum safe viewing distance
4. To convey special importance for portions of the message
5. To improve legibility for persons who have vision problems with small text
Example of text message letter heights and *minimum safe viewing distances.
* Minimum safe viewing distance refers to the closest distance a person can be to the label and still have time to follow the safety label’s message to avoid the hazard.
|Minimum Safe Viewing Distance||Minimum Letter height for Favorable reading conditions||Recommended Letter height for Unfavorable reading conditions|
|1 ft or less*||0.08″||8 points||0.084″||8.4 points|
|2 ft||0.10″||10 points||0.168″||16.8 points|
|3 ft||0.12″||12 points||0.252″||25.2 points|
|4 ft||0.14″||14 points||0.336″||33.6 points|
|5 ft||0.16″||16 points||0.420″||42 points|
|6 ft||0.18″||18 points||0.504″||50.4 points|
|7 ft||0.20″||20 points||0.588″||58.8 points|
|8 ft||0.22″||22 points||0.672″||67.2 points|
*0.08″ (8 point / 2mm) type is the suggested minimum type size for use on product safety labels, except for small products, 0.06″ (6 point / 1.5mm) type may be used.
Safety Label: Recommended Label Placement on Equipment
It is well recognized that in many instances, well designed and properly placed safety labels can increase operator and maintenance personnel awareness of the inherent hazards involved when working with machinery.
When installing labels on equipment we recommend to keep in mind the following criteria. The label needs to:
• Be readily visible to the target audience (personnel that may be in contact with the hazard)
• Alert the viewer to the hazard in time to take appropriate action
• Be applied on or adjacent to the area where the hazard is present
• Be permanently affixed to the equipment
• Be applied only to a surfaces that is clean and free of dirt, dust, grease and moisture. If the surface is painted, ensure that the paint is dry
• Be pressed on after applying it to the surface; one or more passes over with a rag or roller will ensure that the label is completely glued on the surface and will not fall off
