Webinar Recap: Understanding Symbol-Based Warnings in Modern Equipment Design
On Tuesday, January 27, 2026, we hosted a webinar led by Angela Lambert, Director of Standards Compliance at Clarion Safety Systems, exploring the current state of product safety and liability alongside the development of best practice on-product warnings. Attendees walked away with insight on creating effective warnings and understanding how symbol use as well as the latest ANSI and ISO safety label formats fit into broader product safety and risk reduction strategies. In case you missed it, here’s a brief overview, and information on more educational opportunities from the Clarion Safety team.
Why This Topic Matters
Manufacturers, safety professionals, and product designers face increasing pressure to develop safety labels, safety signs, warnings, and instructions that are not only in line with domestic and global standards, but are also effective for diverse audiences. With industry trends toward automation and global distribution, symbol-only and wordless warnings are becoming more common. Yet, these formats have their own complexities when being practically applied, and raise questions about when and how to use them properly.
Key Highlights from the Webinar
1. Symbol-Based Warnings and Standard Frameworks
In our webinar, Angela provided a comprehensive overview of how ANSI Z535.4 and ISO 3864-2 standards apply to symbol-based warnings on products. Attendees learned how these standards accommodate wordless and symbol-only formats, and why such formats can be useful – especially for global audiences – when designed and applied appropriately.
Topics covered included:
- How ANSI and ISO address symbol-only and wordless labels
- When symbol-only warnings are appropriate
- Common misunderstandings about symbols and their effectiveness
- How to use standardized symbols to support comprehension across markets
2. Warnings Within the Risk Reduction Hierarchy
The session emphasized that warnings do not replace engineering controls or machine safeguards. Instead, they function as part of a comprehensive risk mitigation strategy. Angela explained how effective warnings support a layered approach to safety.
3. Global Considerations and Standard Updates
With equipment increasingly reaching global markets, the webinar covered how ISO and ANSI standards help harmonize warning formats, whether they’re being used in the U.S. or internationally. Angela also discussed the importance of standards review cycles (such as the upcoming 2027 ANSI Z535 revision) and how manufacturers can prepare for potential updates that may affect their compliance strategies.
4. Live Q&A Insights
During the live Q&A segment, participants asked practical questions about real-world applications, from choosing between words and symbols, to evaluating comprehension outcomes and aligning warnings with legal duties to warn. These exchanges provided useful context for applying standards in specific organizational settings.
