Crane Crushing Hazard Warning Sticker – Sound Horn Before Swing

This crane crushing hazard warning sticker carries an operator reminder to sound the horn and verify that personnel are clear before actuating swing or another function. Its text-only design has a rectangular red DANGER header with a triangular alert symbol. Compare the complete warning and dimensions with the label specified for your crane or boom truck before replacing a missing or unreadable decal.

Printed Warning

DANGER — CRUSHING HAZARD

Death or serious injury could result from being crushed by moving machinery.

Before actuating swing or any other function. Sound the horn and verify that all personnel are clear of rotating and moving parts.

The wording and punctuation above reproduce the artwork. Sounding the horn and verifying personnel clearance are separate actions in the printed instruction. Sounding a horn alone does not establish that the area is clear. This decal provides a warning reminder, not a horn, personnel-detection device, barrier or complete operating procedure.

Replacement Decal Details

• English-language text-only design
• Rectangular DANGER header with triangular alert symbol, described here as ANSI-style

The header terminology describes its appearance, not certification or proof of standards compliance. Match the complete printed instruction to your equipment requirements.

Oval-Header Alternative

For the same printed crushing-hazard and horn reminder with an oval DANGER header, see the OSHA-style crane crushing hazard warning sticker, C-007O. Both listed versions measure 4¾ × 3¾ inches.

General Placement Guidance

Follow the manufacturer's decal map and preserve the original warning position when known. For a cab-operated crane, general guidance is a readable fixed interior panel near the operating position. For a ground-control boom truck, use a fixed panel beside the applicable controls where the operator can review the instruction before actuating functions.

These are general recommendations, not verified factory locations for every model. Do not obscure windows, controls, instruments, load charts, identification plates or other warnings. This operator reminder does not replace exterior warnings intended for people approaching moving machinery. Follow the supplied application instructions.
