Machine Safety Labeling in the 21st Century

THE IMPORTANCE OF MACHINERY SAFETY LABELS

If your company manufactures machinery that has potential hazards associated with its transportation, installation, use, maintenance, decommissioning, and/or disposal, you most likely have a strong need to create effective product safety labels.

This task must be done right. Simply put, the stakes are too high for this job to be done incorrectly – people’s lives and your company’s financial well-being are on the line. From my vantage point of having played a leading role on standards committees in this field over the past twenty five years, I’ve seen first-hand how safety labels can do one of two things:

1. If properly designed, they can dramatically reduce accidents. This not only improves a product’s overall safety record, but adds to a company’s bottom line by reducing product liability litigation and insurance costs.

2. If poorly designed, needed safety communication does not take place and this can lead to accidents that cause injuries. When such accidents happen, companies spend hundreds of thousands (if not millions) of dollars settling or fighting lawsuits because their products lacked “adequate warnings.”

With the rise in product liability litigation based on “failure to warn” over the past several decades, product safety labels have become a leading focal point in lawsuits faced by capital equipment manufacturers.

TOOL NUMBER ONE: THE STANDARDS

As a manufacturer, you know that your legal obligation is to meet or exceed the most recent versions of standards related to your product at the time it is sold into the marketplace. Warning label standards are the first place you must turn when it comes to defining your product safety labels.

Up until 1991, there was no overarching, multi-industry standard in the U.S. (or in the world, for that matter) that gave definitive guidance on the proper formatting and content for on-product warnings. That changed nationally with the publication of the ANSI Z535.4 Standard for Product Safety Signs and Labels in 1991, and internationally with the publication of ISO 3864-2 Design Principles for Product Safety Labels in 2004.

Following the design principles in these standards will give you a starting place for both the content and format choices you have to make for your products’ safety labels. Note that both of these standards are revised every five years, or so, and it’s important to be aware of the nuances that would make one format more appropriate for your product than another.

TOOL NUMBER TWO: RISK ASSESSMENT

From an engineering perspective, this job is to identify potential hazards and then determine if they need to be designed out, guarded, or warned about.  From a legal perspective, this job is to define what hazards are “reasonably foreseeable” and “reasonable” ways to mitigate risks associated with hazards that cannot be designed out. Here is where risk assessment comes into play.

In today’s world, a product is expected to be designed with safety in mind. The risk assessment process helps you to accomplish this task. At its most basic level, risk assessment involves considering the probability and severity of outcomes that can result from potentially hazardous situations.

After identifying the potential hazards related to your product at every point in its lifecycle, you then consider various strategies to either eliminate or reduce the risk of people interacting with these hazards.

The best practice risk assessment standards that exist today (i.e. ANSI Z10, ANSI B11, ISO 31000, ISO 31010) provide a process to use to quantify and reduce risks. Using these standards as the basis for a formalized risk assessment process will not only help you to develop better safety labels and a safer product, but it will also provide you with documentation that will help you to show the world that you are a safety-conscious company who uses the latest standards-based technology to reduce risks.

TOOL NUMBER THREE: GLOBAL WARNINGS THAT USE SYMBOLS

A large number of machinery manufacturers sell their products around the globe and when this is the case, compliance with global standards is a requirement.

The ANSI Z535.4 and ISO 3864-2 product safety label standards, and the EU machinery directive, place an emphasis on using well-designed symbols on machinery safety labels so information can be conveyed across language barriers. Adding symbols also increases a labels’ noticeability. The use of symbols to convey safety is becoming commonplace worldwide, and not taking advantage of this new visual language risks making your product’s safety labels obsolete and non-compliant with local, regional, and international codes.

It should be noted that sometimes symbols, alone, cannot convey complex safety messages. In these cases, text is still used. When shipping to non-English speaking countries, the trend today is to translate the text into the language of the country in which the machine is sold. Digital print technology makes this solution much more cost effective and efficient than in the past.

The safety labels that appear on your products are one of its most visible components. If they do not meet current standards, if they are not designed as the result of a risk assessment, and if they don’t incorporate well-designed graphical symbols, your company risks litigation and non-conformance with market requirements. 

Most importantly, you may be putting those who interact with your machinery at risk of harm. Making sure your product safety signs and labels are up-to-date is an important task for every engineer responsible for a machine’s design.
