This is how the laser Z136 committee was formed, and in April 1973 the first “Safe Use of Lasers” standard was published. One result of the standard was the creation of warning signs and label requirements — the best known being the “Danger” sign that first appeared in an official capacity. While the Z136 series of laser standards is officially only guidance to laser users, it’s what the Occupational Safety and Health Administration (OSHA) and other regulatory groups rely on for laser safety protocols.

The hallmark red Danger sign has been the standard entryway posting for 43 years and is posted wherever Class 4 lasers are in use. The sign has gone through some minor changes over the years, but the prominent messaging has remained the same.

In 2014, however, a major change took place. The prominent “Danger” wording was replaced with the word “Warning,” and the background was altered from red to orange. But despite this fairly seismic change, all previous “Danger” versions were grandfathered in and are therefore compliant with the new standard. Many, if not most, remain in place.

Sowing seeds of confusion

And herein lies the confusion. The word “danger” implies a high risk of fatality if one is exposed to the hazard, whereas the word “warning” indicates a lesser risk. The rationale behind the change was to bring the prior Z136.1 standard and ANSI sign standard Z535.2 in harmony with one another; this prevents a facility from being cited by an inspector for not being compliant with the preferred standard. Today, the word “danger” is only required for laser systems of 1 kW and above.
