In June 2015, another Globally Harmonized System of Classification and Labelling of Chemicals (GHS) deadline passed — a deadline that called for all chemical manufacturers and distributors to fully comply with the new, more detailed labeling requirements.

How did they do? As expected, companies that started early, involved the proper information technology (IT) and regulatory personnel, and approached the mandate as an opportunity to evaluate and update their existing systems and practices were by and large successful in meeting the deadline and complying with labeling requirements.

Compliance concerns

As many have learned, GHS compliance is a cumbersome process involving multiple factors, including label size and material, printing volume, number of stock keeping units (SKU), the host printing system, existing equipment, and software. Knowledgeable personnel must review and understand all of these factors, gather individual product information, redesign label elements to include pictograms, signal words and hazard, and offer precautionary statements. Then they must work with environment, health and safety (EHS) and IT personnel to execute label production using the right printing equipment and label media.

These changes and the need to potentially requalify label media and printing supplies such as ribbon, toner and ink to meet both GHS and internal specifications for adhesion, durability and internal operational needs proved to be a daunting task. Successful companies saw the magnitude of these processes and got assistance from experienced integrators who helped facilitate the connection between the label media/supplies, printing equipment and the IT host for effective implementation of a comprehensive GHS-compliant system.

Unfortunately, and also as expected, some companies underestimated the amount of time the process would take – for complex operations, up to nine months. They waited too long to get started, consulted too few or under-qualified personnel, and sometimes lacked an understanding of the interdependent relationship between label printing and IT infrastructure. Some faced the added challenges of embedded structures on existing labels such as label numbering, which are sometimes proprietary and designed for one specific type of printer. These structures do not easily translate to new GHS printer technology, causing the company to have to re-engineer that part of the process. This slowed down – and sometimes even stalled – the time to implementation.

Still others allotted a reasonable amount of time for the transition, gathered the appropriate personnel and formulated a solution, but nevertheless they missed the deadline because of a delay in delivery of printing equipment. Following the June 1 deadline, one chemical manufacturer reported being 12 weeks out for delivery of printing equipment and materials because of the increased demand fueled by GHS. Across the landscape, this appears to be a legitimate reason for missing the deadline.  Printing equipment manufacturers and suppliers are confirming these reports, stating they are behind in production and delivery due to GHS and the increased demand, especially of thermal printers and supplies.

Thermal printers have become a popular choice for producing GHS labels. Many companies have had positive experiences previously using single-color (black) thermal printers combined with pre-printed color labels to meet past regulator labeling requirements, which explains their desire to continue using a thermal solution to produce GHS labels. Thermal printers are built for tough environments; offer high-volume options; can print red and black at the same time; can produce roll output for use with automatic applicators; and can print longer, wider labels than many other GHS-capable printers.

For many, a lot of work remains, but benefits can be gained, especially for larger enterprises. Complex, multi-facility companies, for example, may experience cost savings revealed by a thorough GHS review. They may look at several sites and discover one plant is doing something completely different than all the others.

This can lead to a system realignment, reduction of label formats, equipment consolidation and material savings that otherwise might have gone unnoticed. Another example may be found in the label design. A simple adjustment to the placement of a diamond pictogram, for instance, may use less printer ribbon, saving money over time. A few have also taken advantage of on-demand color printing options now available, and they have used these options to produce marketing-quality logos on the product label along with the required GHS information.

Ultimately, printing color labels on demand is more efficient than pre-printing, but color printing itself is expensive. Some manufacturers may have been unprepared for this expense, but through a review of their label processes and with input from seasoned integrators, they have found ways to improve long-term efficiencies and effectively reduce the added expenses of printing color GHS labels.

Much of the chemical manufacturing industry is in some stage of transition to full GHS compliance, and another deadline recently hit. Dec. 1, 2015 marked the end of the grace period for distributors to deliver old, pre-GHS-labeled products. Now, all chemical products must display the new GHS label. At this point, it is unclear how the Occupational Safety and Health Administration (OSHA) will respond to those who missed the 2015 deadlines and what effect, if any, that may have on future deadlines.

Some industry professionals speculate OSHA may be lenient due to the printing industry’s production and delivery backlog, but a definitive response remains to be seen. Were the GHS process to display its own label right now, the signal word would read “warning” along with pronouncing a precautionary statement for chemical manufacturers to take GHS compliance seriously.


How to follow label printing compliance

Evaluate printing needs. First, consider specific needs. Take container size into account as well as types of labels and ambient factors such as temperature and moisture levels in the containers’ destinations. Also remember most manufacturers have printing needs aside from GHS-compliant labels

Consider the law. Required warnings, symbols and identifiers can govern other label considerations, such as size. Consider not only current needs, including graphical elements, but also any changes that may be implemented in the future.

Estimate costs. Total cost of ownership is an important factor to evaluate. Scrutinize not only the potential cost of each label, but also the cost of each individual printed image.

Take a holistic approach. It is often more beneficial to use one partner for all printing needs rather than having several entities involved. This ensures that all components work well together. It also ensures consistent quality, results and good customer service.
