Enhancing Mechanical Safety: Introducing the New ISO Mechanical Lockout Symbol to Our Catalog

10th Sep 2026 Clarion Safety Systems

Workplace and product safety evolve constantly, and clear visual safety communication is essential to protecting workers and end-users from severe mechanical hazards. Whether you manufacture industrial machinery or manage facility equipment, ensuring that lockout procedures are clearly communicated before maintenance or repair work begins can prevent devastating injuries.

We are excited to announce that we have expanded our website catalog and online Custom Label Designer to include new product safety labels featuring ISO M068—the newly registered ISO symbol for mechanical lockout.

Moving Beyond Electrical Lockout: The Power of ISO M068

While traditional lockout safety symbols have often focused on electrical power isolation, the new ISO symbol M068 specifically targets moving mechanical components.

Key Details of ISO M068:
  • ISO Reference: ISO 7010 / M068

  • Category: Mandatory Action

  • Symbol Meaning & Referent: Lock moving mechanical parts

  • Function & Description: Signifies that moving mechanical parts must be locked before accessing an area to carry out maintenance or repair work.

  • Visual Design: A mandatory blue circle containing a white graphic of two interlocking gears with a padlock positioned above them.

This internationally recognized ISO 7010 safety symbol visually communicates critical safety instructions, warning users to avoid crushing, pinching, and entanglement hazards before entering dangerous machinery zones.

Standards Alignment and OSHA Compliance

Instructions and visual safety labels on equipment do more than just inform; they help businesses stay compliant with safety standards and regulations.

Our safety labels are expertly designed in line with ANSI/ISO standards and help meet OSHA compliance requirements:

  • ISO 3864-2: Guides the use of standardized graphical symbols in safety labels and instructions.

  • ANSI Z535.4: Encourages the integration of graphical symbols to enhance hazard recognition and legibility across language barriers.

New Products Available Now in Our Catelog

We’ve added the new ISO M068 symbol across a variety of label formats and standard sizes so you can select the exact layout your application demands.

1. Symbol Only Labels (Series: IS7260-)

If you require clean, text-free visual communication for global distribution, symbol-only versions are available in multiple standard sizes:

  • Size A: 3.00” x 3.00”

  • Size B: 2.00” x 2.00”

  • Size C: 1.50” x 1.50”

  • Size D: 0.75” x 0.75”

2. Multi-Hazard & Combination Labels

For labels requiring signal words, text, or combination safety messages, we’ve integrated the new symbol into several popular layout configurations (such as item H1143/7260-388WH, similar to our classic H1143-388WH format).

Other new catalog additions featuring mechanical lockout warnings include:

  • Warning: Moving Parts Follow Lockout Procedure Label

  • Warning: Moving Parts Belt Drive Follow Lockout Procedure Label

  • Danger: Moving Parts Do Not Operate With Guard Removed Label

  • Warning: Moving Parts Crush Follow Lockout Procedure Label

3. Custom Label Designer Integration

Need a custom wording, tailored header, or unique size combination? The new ISO M068 symbol is now available directly within our website’s Custom Label Designer, letting you build fully customized visual safety labels in minutes.

Engineered for Demanding Industrial Climates

A safety label’s performance is only as reliable as the materials behind it. Our new ISO M068 labels are printed on premium 3M polyesters designed to withstand harsh industrial environments, high visibility requirements, and heavy washdowns:

  • Indoor Polyester (‘P’ Material): Premium 3M polyester offering excellent chemical resistance; performs best in temperatures ranging from -40°F to 300°F.

  • Outdoor Polyester (‘B’ Material): Weatherable 3M polyester built to withstand strong ultraviolet light, heat, water, and chemical washdowns; performs in temperatures from -40°F to 175°F.

  • Environmental Compliance: Both standard materials are compliant with RoHS, CRoHS, and REACH standards.

Unmatched Standards Leadership

When you choose Clarion Safety, you gain access to decades of direct involvement in national and international standards committees.

Our head of standards compliance, Angela Lambert, brings 15 years of expert experience in product safety, warnings, and liability:

  • Chair of the ANSI Z535.1 subcommittee (focused on safety colors in visual communication).

  • Delegate Representative to the ANSI Z535 committee.

  • Delegate Representative to ANSI for the ISO/TC 145/SC 2/WG 1 committee—the working group responsible for the ISO 7010 library of registered symbols and the ISO 3864 standard series.
