Although history only records back so far, I am certain (based on my experiences with sharp and heavy objects) that humans have been injuring themselves with tools, and the stuff they make with them, since the beginning of time. In fact, recorded history DOES bear this out…the famous Code of Hammurabi (circa 1750 B.C.) set specific amounts of compensation for specific injuries, as did laws from all over the ancient world, from the empires of Rome to China. Since then, we’ve come a long way in regulating safety not only for the worker in the workplace, but in public places, homes, and workplaces where manufactured products are used.
UL LLC (or Underwriters Laboratories, as they were known throughout the 20th Century) is a safety consulting & certification company founded in 1894 by an electrical engineer named William Henry Merrill. A year earlier, an insurance company hired Merrill to perform a risk assessment and investigation of new potential clients…George Westinghouse and Nikola Tesla, the proprietors of the Palace of Electricity at the 1893 Chicago World’s Fair. It was this experience that made him realize the potential for such an agency to test and set standards for product safety at the dawn of a new age of technology development. And 120 years on, the benefits in safety & protection have been proven many times over.
One of the more critical accreditations that a manufacturer can receive for a product is the UL Classified Mark. This differs from other markings (like the ones shown above for Certified, Listed, or Recognized) in that Classification means that samples of the product were tested & evaluated with respect to certain properties of the product.
EXAIR’s new Hazardous Location Cabinet Cooler Systems bear the UL Classified Mark. This means they meet the stringent UL requirements for installation on purged electrical enclosures in specific classified areas:
- Class I Div 1, Groups A, B, C and D
- Class II Div 1, Groups E, F and G
- Class III
When choosing products for use in classified areas, it’s critical to ensure safety through compliance, and the HazLoc Cabinet Cooler Systems allow you to do that, with simplicity and reliability. If you’d like to discuss an enclosure cooling application, in or out of a classified area, give me a call.
