Commercial & Food Service Water Treatment Equipment
“The Dining Room Table” | Frank Weston Benson
We follow the development trajectory of the IAPMO Group’s suite of standards because of IAPMO’s tenure in water safety codes and standards in the United States. IAPMO co-develops selected consensus documents with the American Society of Safety Professionals (ASSP). The landing pages for the IAPMO and ASSP onsensus product development enterprises are linked below:
Because the education facility industry is steward to 100’s of thousands of food preparation enterprises we track leading practice in the technical standards for water systems that support safety in the food services that are essential to education industry food preparation enterprises: ASSE 1087‐2018 Performance Requirements for Commercial and Food Service Water Treatment Equipment Utilizing Drinking Water.
From the ASSE 1087 prospectus:
Commercial water treatment equipment is used in point-of-entry and point-of-use applications connected to building plumbing to improve the water-quality characteristics of potable water. This standard includes testing requirements for components and complete systems. Electrical compliance is not covered by the standard. Plumbed water treatment units include any device or component, point-of-entry and point-of-use that is used in building to improve the quality of the water. This standard covers all water-treatment products that are connected to the building’s plumbing system for potable water. This standard is not intended to cover water-treatment products used for process water or wastewater applications. Examples of water-treatment equipment include: Deionization, Filters, Softeners, Physical Devices, Reverse Osmosis, UV, Ozone, and Distillation. Tests verifying claims regarding changes to water chemistry, microbiology, and aesthetics (i.e., smell, taste, appearance, etc.) are not included in this standard. Devices may claim such performance via other standards or test protocols.
Large research universities with district energy systems will supply high temperature potable water to healthcare facilities for centralized steam sanitation, to housing facilities for food preparation and bathing. Some systems are local to a single facility or a group of facilities.
George Mason University
While the public commenting opportunities for the 2018 release of this particular standard is now closed; the project administrators typically collect public input across the full 3 to 5 year time frame in which the current standard is active. We link the public review copy below but keep in mind that it has been superseded:
For information about how to obtain the completed document or how to participate on this or any other ASSP technical committee you may contact ASSE directly: CLICK HERE. Additionally, we host periodic Water Management and Food Safety standards teleconference during which time to sweep through the rapidly expanding constellation of water management documents relevant to our industry and others. See our CALENDAR for the next online meeting; open to everyone. Use the login credentials at the upper right of our home page.

Electrical Safety in the Workplace
“Telegraph Poles with Buildings” | Joseph Stella (1917)
Optimal electrical safety and reliability is strongly correlated with electrical maintenance — i.e. functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, governmental, and residential installations. These activities take place either before or after a failure. In either case, normal maintenance is “likely” to expose electrical workers to hazard. In healthcare facilities, for example, there is risk of failure of backup systems (described in Article 517 of the National Electrical Code) unless maintenance is undertaken while equipment is live.
The trade-offs are well known. Because of optimal maintenance, we have a commercial airline industry. Because of optimal maintenance the United States has one of the most reliable power grids in the world.
In electrical power systems, equipment and systems that control energy are designed to work, perhaps, only once or twice dependably in 25 to 50 years; if that. Only safety-by-design and recommended maintenance can sustain the likelihood that safety and reliability expectations can be met. Electrical maintenance usually involves exercising breakers, testing trip settings, confirming signaling paths in controls, software and the like. Safety by design usually involves applying methods to minimize occupational hazards early in the design process, with an emphasis on optimizing employee health and safety throughout the life cycle of materials and processes.
There are several leading practice documents in this space; one of the first among them NFPA 70E Electrical Safety in the Workplace — a trademarked document available for use by the public:
You will likely find NFPA 70E incorporated by reference into federal occupational safety laws and in state-level electric utility regulations. The technical committees writing the 2021 revision met in August 2018 and again in July 2019 and produced the draft results linked below:
First Draft Report 2021 NFPA 70E
Second Draft Report 2021 NFPA 70E
Note the considerable “back-and-forth” on stored energy system, interactive, direct current and multiple source safety. There are others.
After the Second Draft Report is released for public review no later than January 22, 2020, NITMAM comments are due February 19th.
We usually coordinate our response to NFPA electrical safety consensus products with IEEE SCC-18 and IEEE Education & Healthcare Facilities Committee which meets 4 times monthly in European and American time zones. See our CALENDAR for the next online meeting; open to everyone.

Energy Monitoring Equipment
Underwriters Laboratories / Northbrook, Illinois
The proposed first edition of Underwriters Laboratories Standard for Safety for Energy Monitoring Equipment, ANSI/CAN/UL 2808, covers submetering equipment and open and enclosed type current sensors intended for factory or field installation within distribution and control equipment such as panelboards, switchboards, industrial control equipment, and energy monitoring/management equipment.
Installation is in accordance with the National Electrical Code, ANSI/NFPA 70 and the Canadian Electrical Code (CE Code), CSA C22.1. These requirements also cover “Service Entrance” enclosed-type current sensors intended for indoor and outdoor use.
