UL's Hazardous Locations (HazLoc) Operations

Strongest Path to the Global Marketplace

Underwriters Laboratories Inc. (UL) is an independent, not-for-profit product safety testing and certification organization. We have tested products for public safety for more than a century, and have been involved in the global conformity assessment of electrical equipment for use in, or relating to, hazardous locations (explosive atmospheres) for more than 85 years.

In addition to being the leader in product safety testing and certification within the US, our involvement in the testing and certification of HazLoc equipment is recognized and respected around the world.

Our HazLoc family members include UL USA (Northbrook, IL & Anchorage, AK USA), UL International Demko A/S (Herlev Denmark), UL do Brasil Ltda. (São Paulo Brasil), UL Ibérica (Barcelona Spain), UL International Germany GmbH (Neu-Isenburg Germany), UL International (UK) Ltd (Guildford, Surrey United Kingdom), and UL India (Bangalore India). The strength of our global HazLoc team is its ability to meet your needs -- especially in the area of turnaround time and global market access. Regarding turnaround time, we have over 90 highly-trained and customer-focused HazLoc engineering staff ready to service our customers. Regarding market access, we are the only safety testing and certification organization that maintains the following global HazLoc accreditations:

  • Internationally: Ex Certification Body (ExCB) and Ex Testing Laboratory (ExTL) status under the IECEx Scheme
  • In the European Union: Notified Body (NB) status under the ATEX Directive,
  • In the United States: Nationally Recognized Testing Laboratory (NRTL) under OSHA,
  • In Canada: Accredited Certification Body (ACB) under the Standards Council of Canada (SCC),
  • In Brazil: INMETRO accreditation, and
  • In Japan: Designated Foreign Testing Body (DFTB) under the Ministry of Health, Labour and Welfare

Recognizing that these accreditations can not address all global market access needs, we also maintain and are expanding relationships with other local HazLoc testing and certification organizations throughout Asia, Australia, the Commonwealth of Independent States, Europe and Latin America.

These global relationships and accreditations allow for truly one-stop-shopping for your global conformity assessment needs under either the Division or Zone hazardous locations classification systems.
