Designing A Grow Facility Using Safer Lighting Equipment – Ed Joseph – principal engineer – Lighting Safety, Appliances, HVAC and Lighting division, UL

One of the many essential best practices for a well-designed grow facility is to provide a safe grow environment for visitors and workers that enter the facility. Lighting equipment and horticultural systems that often include the integration of lighting; power distribution circuits; plumbing components such as water pumps, solenoid valves; and other controls are an essential part of a grow facility design. Meeting safety requirements for this equipment is as important as the equipment’s ability to provide proper light and nutrients that result in a high plant production yield rate. It is also important to be aware of the National Installation Codes in the U.S. that apply to horticultural lighting equipment installations. During this presentation attendees will learn about:

  • Introduction to UL 8800, the new safety Standard for horticultural lighting equipment and systems
  • The types of lighting equipment covered by UL 8800
  • Several key differences between horticultural luminaires and luminaires intended for general illumination
  • How the safety requirements in UL 8800 address these differences
  • The importance of installing horticultural lighting equipment per the equipment manufacturers installation instructions
  • The new section added to Article 410 in the 2020 edition of the U.S. National Electrical Code – NFPA-70 which addresses installation requirements for horticultural luminaires


Cannabis Extraction, Processing Systems and Booth Certification – Bob Deadman – senior staff engineer – Energy and Power Technologies division, UL

The extraction process often creates hazardous conditions due to fire, shock, high pressures and flammable solvents being released during processing. Mitigation of these hazards for extractors, booths and post processing equipment is important to prevent accidents. Achieving certification to UL 1389, the Standard for Plant Oil Extraction Equipment for Installation and Use in Ordinary (Unclassified) Locations and Hazardous (Classified) Locations, manufacturers can design and produce new processing equipment according to this consistent set of criteria and thereby avoid delays in the building permit process. This presentation will discuss certification of cannabis extraction systems, post-process equipment and booths along with changes to the 2021 NFPA 1 and IFC that will reference certification to UL 1389.


Plant-Oil Extraction Equipment – European Compliance (ATEX and PED) – Mark Chauhan – senior project engineer – Michael Slowinske – engineering manager – Energy and Power Technologies division, UL

Manufacturers of plant-oil extraction equipment wishing to export their machines to Europe will need to comply with safety regulations for pressure vessels and explosion protection.  Learn about the applicable European laws and standards in this introductory seminar on the Pressure Equipment Directive (PED) and Explosive Atmospheres Directive (ATEX).


HazLoc Basics Track

Designing for First Pass Certification – David Malohn - staff engineer Energy and Power Technologies division, UL

Certifying equipment for hazardous locations can be a costly and sometimes lengthy process. It is possible to be more cost-efficient and reduce turnaround time (TAT). We’ll examine ways manufacturers can achieve these goals and mitigate delays due to significant compliance issues. UL will share expertise, best practices and examples about all types of products and protection techniques.


Specific HazLoc Applications Track

Unmanned Robots and Drones in Global Hazardous Locations – Paul Kelly – principal engineer Energy and Power Technologies division, UL

Whether flying through the air, e.g. drones, crawling over ground, e.g. robots, or swimming on or underwater, e.g. saildrones, remotely or autonomously controlled vehicles have established their benefits in ordinary (unclassified) locations. These benefits include monitoring, exploration, protection and delivery. Now, the benefits of these unmanned vehicle systems are being recognized in hazardous (classified) locations. Learn about the progress and challenges associated with the use of these vehicles in explosive atmospheres.
