Warning Labels

We provide quality products to a variety of industries.

Custom Industrial Warning Labels

UL authorized. OSHA compliant.

Custom industrial warning labels built from your approved signal words, messages, and symbols, matched to the reader, the task, and the placement. Produced as a UL approved label supplier in an ISO 9001:2015 certified facility.

About warning labels

Notifying operators of machine hazards, weights, and specifications while they are using your equipment is a basic part of putting a machine into service. A warning label displays that information at the point of operation, at all times, without depending on anyone having read the manual.

Which means the label has one job and one failure mode. If it is still there and still readable in year twelve, it worked. If it has faded, peeled, or been scoured off, the hazard is unmarked and the machine is carrying a risk nobody can see.

  • Hazard and danger warnings at the point of operation
  • Pinch point, crush, and entanglement warnings on moving assemblies
  • Electrical hazard and arc flash labels
  • Hot surface, pressure, and chemical exposure warnings
  • Weight, capacity, and load limit notices
  • Lockout and service warnings for maintenance access points

Signal words and symbols

Industrial warning labels follow a signal-word hierarchy that operators across industries already recognize. Using it consistently is most of what makes a label work, because the operator does not have to read the whole message to know how much attention it needs.

DANGER
A hazard that will cause death or serious injury if not avoided. Reserved for the most severe situations, and weakened by overuse.
WARNING
A hazard that could cause death or serious injury. The most common signal word on industrial equipment.
CAUTION
A hazard that could cause minor or moderate injury.
NOTICE
Information about practices not related to personal injury — equipment damage, or a procedure that must be followed.
Symbols and pictograms
Carry the hazard across language barriers and at distances where text cannot be read. Essential where equipment is operated by a multilingual workforce or exported.

We produce labels to the standard your specification calls for, and to your approved artwork. If you tell us the standard you are working to, we will proof against it.

Warning label materials and finishes

Choose from a variety of materials, finishes, colors, and adhesives. Unlimited PMS, standard, or custom colors are available.

Polycarbonate — .005″–.125″

Polyester — .002″–.010″

MetalWhere the warning must outlast any flexible substrate, the same message can be produced as an etched or Metalphoto® plate. See metal nameplates.

Warning label durability

A faded warning label is worse than no label, because it signals that the hazard was marked while no longer communicating what it is. Three things decide whether yours is still doing its job in a decade.

Substrate
Polyester over vinyl for anything outdoors or handled. Vinyl conforms better to curves and costs less, but gives up service life.
OverlaminateA clear film over the printed face takes the abrasion, UV, and chemical contact instead of the ink. UV clearcoat is available to prevent fading. See laminating.
Adhesive
Matched to the surface. A label specified for bare metal and applied to textured powder coat is the most common reason warning labels lift at the corners.
Sub-surface printing
On clear substrates, the graphics are printed on the underside so the material itself protects them. Nothing abrasive ever touches the ink.

Tell us the exposure honestly. Wash-down, direct sun, solvent contact, and abrasive dust each change the construction, and the cost difference is usually small against the cost of replacing labels in the field.

Formats and delivery

Finished labels ship in rolls, strips, or individual pieces, sheared, trimmed, die cut, or digitally cut to shape.

  • Individual pieces for low-volume or large-format warnings
  • Rolls wound to your applicator where the same label goes on every unit
  • Kiss-cut on a carrier sheet so an operator peels them in sequence
  • Consolidated with the rest of a machine’s decals as a label set
  • Bundled with plates and panels as a kit

How a warning label order runs

  1. Tell us about the hazard and the machine. What the label warns about, where it mounts, and who reads it. Our seasoned art department turns artwork into a press-ready proof at no charge.
  2. We recommend the construction. Substrate, overlaminate, and adhesive, chosen against the mounting surface and the exposure.
  3. You approve the proof. Wording, symbols, color, and size are signed off before anything is printed.
  4. Production. Most jobs finish 7–10 days after the proof is approved, in an ISO 9001:2015 certified facility. Rush work runs 3–5 business days for an additional fee.
  5. Delivery or release. Orders ship within a 10% over/under quantity standard, or run against a stocking program.

Warning label RFQ checklist

  • The wording and any symbols, or the current label if you are replacing one
  • Finished size, and whether a custom shape is needed
  • Any standard or customer specification the label must meet
  • What the label mounts to, including the surface finish
  • What it is exposed to — sun, wash-down, solvents, abrasion, temperature
  • Whether you need rolls, strips, individual pieces, or a set
  • Quantity and your timing, including the date the line actually needs parts
