Outdoor Deicing & Snow Melting

Electrical Safety

“Snow at Argenteuil” | Claude Monet (1875)

Today our focus turns to outdoor electric deicing and snow melting wiring systems identified as suitable for the environment and installed in accordance with the manufacturer’s instructions.  They work silently to keep snow load from caving in roofs and icicles falling from gutters onto pedestrian pathways.

While the voltage and ampere requirement of the product itself is a known characteristic, the characteristic 0f the wiring pathway — voltage, ampere, grounding, short circuit, disconnect and control — is relatively more complicated and worthy of our attention.   Articles 426-427 of the National Electrical Code is the relevant part of the NEC

Insight into the ideas running through technical committee deliberations is provided by a review of Panel 17 transcripts:

2023 NEC Panel 17 Public Input Report (633 pages)

2023 NEC Panel 17 Public Comment Report (190 pages)

We hold Articles 427 in the middle of our priority ranking for the 2023 NEC.   We find that the more difficult issues for this technology is the determination of which trade specifies these systems — architectural, electrical, or mechanical; covered in previous posts.   Instead, most of our time will be spent getting IEEE consensus products in step with it, specifically ANSI/IEEE 515 and IEEE 844/CSA 293.

Comments on the Second Draft of the 2026 NEC will be received until April 18th.

We collaborate with the IEEE Education & Healthcare Facility Committee which meets online 4 times per month in European and American time zones.  Since a great deal of the technical basis for the NEC originates with the IEEE we will also collaborate with IEEE Standards Coordinating Committee 18 whose members are charged by the IEEE Standards Association to coordinate NFPA and IEEE consensus products.

Industrial electroheating and electromagnetic processing

The global standards for heat tracing systems are developed by IEC Technical Committee 27.  The scope of work for this committee is reproduced below:

Standardization in the field of industrial equipment and installations intended for electroheating, electromagnetic processing of materials and electroheat based treatment technologies Note: The scope of interest covers industrial installations with the use of the following equipment: – equipment for direct and indirect resistance heating; – equipment for electric resistance trace heating; – equipment for induction heating; – equipment using the effect of EM forces on materials; – equipment for arc heating, including submerged arc heating; – equipment for electroslag remelting; – equipment for plasma heating; – equipment for microwave heating; – equipment for dielectric heating; – equipment for electron beam heating; – equipment for laser heating; – equipment for infrared radiation heating. The list presents typical examples of equipment and its applications and is not exhaustive.

Titles in this committee’s bibliography appears to be stable.   As with all IEC titles, they are relatively narrow in scope compared with the titles promulgated by most US standards developing organizations.  Our interest lies primarily in the application of this technology within and around education community buildings.

While heat tracing generally goes un-noticed it is an essential part of cold weather safety.  It is wise to keep pace with its evolution with innovation in materials and controls with the lead.

We maintain this committee’s work on the standing agenda of our seasonal Snow & Ice colloquia; along with US standards developed by UL, IEEE, NEMA, NFPA, ICC, ASHRAE and a few others.  We also collaborate with the IEEE Education & Healthcare Facilities Committee on this topic.  See our CALENDAR for the next online meeting; open to everyone.

Today we break down the catalog for food safety in education communities; with primary attention to consultations from private standard developing organizations and federal agencies charged with food safety.  We do so with sensitivity to animals and plants and sustainability of the global food supply chain.   Many schools are the communal cafeterias for the communities that own and operate them and run at commercial scale.

We prepare responses to public consultations released by standards developing organizations which, in many cases, have significant conformance enterprises.

Heat tracing is a process used to maintain or raise the temperature of pipes and vessels in order to prevent freezing, maintain process temperature, or ensure that products remain fluid and flow through the system properly.

Heat tracing works by using an electric heating cable or tape that is wrapped around the pipe or vessel, and then insulated to help retain the heat. The heating cable is connected to a power source and temperature control system that maintains the desired temperature by regulating the amount of heat output from the cable. Heat tracing is commonly used in industrial applications where temperature control is critical, such as in chemical plants, refineries, and oil and gas facilities.

There are several types of heat tracing, including electric heat tracing, steam tracing, and hot water tracing, each of which have their own unique advantages and disadvantages. The selection of the appropriate type of heat tracing depends on the specific application and the required temperature range, as well as factors such as cost, maintenance, and safety considerations.

There have been several recent innovations that have made it possible for construction activity to continue through cold winter months. Some of the most notable ones include:

  1. Heated Job Site Trailers: These trailers are equipped with heating systems that keep workers warm and comfortable while they take breaks or work on plans. This helps to keep morale up and prevent cold-related health issues.
  2. Insulated Concrete Forms (ICFs): ICFs are prefabricated blocks made of foam insulation that are stacked together to form the walls of a building. The foam insulation provides an extra layer of insulation to keep the building warm during cold winter months.
  3. Warm-Mix Asphalt (WMA): WMA is a type of asphalt that is designed to be used in colder temperatures than traditional hot-mix asphalt. This allows road construction crews to work through the winter months without having to worry about the asphalt cooling and becoming unusable.
  4. Pneumatic Heaters: These heaters are used to warm up the ground before concrete is poured. This helps to prevent the concrete from freezing and becoming damaged during the winter months.
  5. Electrically Heated Mats: These mats are placed on the ground to prevent snow and ice from accumulating. This helps to make the job site safer and easier to work on during the winter months.

Overall, these innovations have made it possible for construction crews to work through the winter months more comfortably and safely, which has helped to keep projects on schedule and minimize delays.

Watch the stars, and see yourself running with them.”

― Marcus Aurelius, Meditations

The consumer discretionary sector is among the largest economic sectors in every nation.   Consumer Discretionary is the term given to goods and services that are considered non-essential by consumers, but desirable if their available income is sufficient to purchase them.  Consumer discretionary goods include durable goods, apparel, entertainment and leisure, and automobiles.  The International Organization for Standardization administers leading practice discovery and promulgation of the standards in a core component of durable goods industry — textiles – through its Technical Committee 38.

We find continued student interest in these technologies so attention to the elevated hazards in research, instructional and display spaces require attention.   We recognize that not every student is interested in cleaning neural network data sets or learning Tensor Flow but wants to devote their energy to making the world a better place by making the world a more beautiful place.

From the ISO/TC 38 prospectus:

STRATEGIC BUSINESS PLAN ISO/TC 38 Textiles

“…Textiles are one of the most important and versatile commodities in the global economy. The textile industries involve provision of raw materials, preparation of fiber production, manufacture of yarns and fibres, manufacture of fabric formation, finishing processing including bleaching, dyeing, printing, coating, special chemical treatments, transformation of the fabric into clothing, upholstery, or industrial/technical textiles, and rope and netting formation. Therefore, the textile industry concerns a variety of entities such as suppliers of raw materials, processors, manufacturers, traders,  distributors, retailers, associated industries such as the laundry industry, government and educational establishments as well as consumers….

…One new field of innovation in the textiles is emerging as the smart textiles which cover either smart textile materials or smart textile systems, including some of them combining technologies with electronic textiles and wearable devices. The uses expected of the smart textiles extend over medical device, general product safety, textile labelling, etc. Our technical committee liaises for cooperation with other technical fields and be responsible for standardization of the textile field of smart textiles….”
