IoT, 5G, M2M and EMC: How We Gonna Play on the Internet of Things?

According to statistics from the WiFi Alliance, 12 billion WiFi-enabled products have been deployed since the year 2000. Another 3 billion are expected to ship in 2016 alone, with device deployments doubling by 2020 (3 million every day).

Moving Toward a Uniform System of Hazard Recognition

This month in our series exploring the latest industry insight on effective product safety label design and symbol usage, we’ll focus on the importance of consistency in the use of symbols and formats for both product safety labels and facility safety signs. For many years, the U.S. Occupational Safety and Health Administration’s (OSHA) regulations for workplace safety signs were based on outdated 1941-era formats. That changed about two and a half years ago. In October 2013, OSHA incorporated the latest versions of the ANSI Z535 safety sign, tag and color standards into its safety regulations, aligning them with today’s best practices. Let’s look at how this change, which allows for consistent sign and label formats using the latest standards, is impacting our products and our workplaces.

The Myth of Accessibility

Almost every safety standard has requirements addressing the accessibility of certain parts.
