4 x 4" - "Attention - Observe Precautions" Labels

These 4 x 4 inch labels display the internationally recognized 'Attention – Observe Precautions' symbol and cautionary text, designed to identify packages, components, and assemblies containing devices that are sensitive to electrostatic discharge. The square format delivers a prominent warning surface that dissipates electrostatic charge awareness at a glance.

Electronics manufacturers, PCB assemblers, medical device packagers, and distribution centers rely on these labels to meet domestic and international ESD marking requirements. The standardized symbol is recognized across multiple countries, making the labels appropriate for both domestic shipments and export compliance.

Each roll contains 500 labels wound on a 3-inch diameter core, compatible with standard tabletop and wall-mount label dispensers. Each roll weighs approximately 2.08 lbs. Compatible dispensers — including tabletop models SL9506, SL9512, and SL9518, and wall-mount models LDM300, LDM450, LDM850, and LDM1250 — are available separately.
