Our wide selection of ANSI Z535.4 safety labels communicate hazard severity through the combined use of signal word, pictorial, and message panel. For equipment sold in the United States, applying labels that conform to ANSI Z535.4 is a recognized component of product liability risk management. Our labels span a wide assortment of hazardous situations across electrical, arc flash, thermal, machine guarding, cutting, chemical, and pinch point hazards.
The labels are constructed with high quality 3M Polyester base w/ 3M Polyester Overlaminate, the materials are UL Recognized and CSA Approved, Rated from -40F to 300F.
ANSI Z535.4 (Product Safety Signs and Labels) defines a structured label format that combines three components to communicate hazard information clearly and consistently:
ANSI Z535.4 defines three signal words for injury hazards, each with a distinct color specified in ANSI Z535.1 (Safety Colors):
Signal word selection must be based on a hazard assessment applying the criteria in ANSI Z535.4 to your specific equipment. Consult the current edition of ANSI Z535.4 directly at webstore.ansi.org for the full selection criteria.
All ANSI safety labels in this catalog are built on a 3M polyester film base laminated with a 3M polyester overlaminate. The overlaminate protects printed ink from abrasion, cleaning solvents, lubricants, and fluids without delaminating or losing legibility.
ANSI Z535.4 (Product Safety Signs and Labels) specifies the signal-word hierarchy (DANGER, WARNING, CAUTION, NOTICE), the color assigned to each signal word per ANSI Z535.1, the safety alert symbol, and the structured three-component label format: signal word panel, pictorial panel, and message panel. The standard also covers signal word selection criteria based on hazard severity and probability, label placement, and durability requirements. The current edition is available at webstore.ansi.org. For signal word selection and design requirements applicable to your products, consult the standard directly.
A safety label that fades, delaminates, or loses adhesion no longer communicates the hazard — and a label that fails in service undermines the manufacturer's intent to communicate the hazard. ANSI Z535.4 addresses label durability as part of compliance. Our labels built on premium UL recognized polyester materials with, UV treated ink, overlaminate, and premium adhesive are designed to maintain legibility and adhesion in both indoor and outdoor uses.
ANSI Z535.4 is the North American product safety label standard, using text signal words (DANGER, WARNING, CAUTION) with color coding and the safety alert symbol. ISO 3864-2 (Design Principles for Product Safety Labels Using Graphical Symbols) is the international counterpart, covering graphical-symbol-based labels without language-specific text. ANSI Z535.4 is referenced by OSHA 29 CFR 1910.145 and is the prevailing standard for US product safety labeling. ISO 3864-2 and ISO 7010 labels are accepted for CE-marked equipment and multilingual facilities. Both standards are available from their publishers — ANSI Z535.4 at webstore.ansi.org and ISO 3864-2 at iso.org/store.
Our labels are build with 3M polyester film base with polyester overlaminate which is UV-resistant and rated –40°F to 300°F, making it suitable for permanent outdoor installation. The construction resists moisture, cleaning agents, and lubricant exposure without ink adhesion loss. The polyester film also has enough flexibility to conform to curved surfaces without lifting at the edges.
