Example of Utility Marker

Why are utility markers valuable?

More than 50% of all utility service interruptions are the result of accidental damage by builders, homeowners, or construction crews. Use durable utility markers made by LEM Products, Inc. to clearly mark for safety and identification. All of our utility markers are available custom-made with your unique message and company logo.

Transformer Labels

LEM transformer product safety labels and safety labels meet the NEMA standards. The NEMA standard requires that two transformer safety labels be placed on each transformer, a WARNING label on the outside of the transformer and a DANGER label on the inside door to provide a secondary line of defense. The permanent pressure sensitive adhesive on LEM transformer markers provides a strong bond to steel and other clean, dry surfaces. Transformer labels are made of tamper resistant film with permanent adhesive that will adhere the safety labels to the transformer and prevent any attempt of removal, keeping the warning of the danger of high voltage permanently in place.

NESC & ANSI Rules:

Section 110A.1 for substations: “A safety sign shall be displayed at entrances…”Sections 381 for pad-mounts: “A prominent and appropriate safety sign should be displayed with the first door…” Section 411D on work rules and signs: “Permanent warning signs shall be displayed in conspicuous places…”LEM Products Inc provides all of the marking required to comply, in both stock and custom formats.

Stakes and Flags

Marking Stakes and Flags

Identify high voltage underground utility lines with LEM’s utility marking flags made of durable PVC material. Available in 7 blank colors and 10 pre-printed legends.
Utility Marking Stakes are another method of identifying buried utility lines. Warning stakes from LEM are available in two styles of construction to accommodate different applications.
The High Performance Marker with the symmetrical three rib design is ideal for roadside delineation applications. It offers the best choice for overall visibility and flexibility. The design combines the strength and characteristics of flat markers with the low bending radius curved type markers.
The Economical Marker is designed for applications where less flexibility and a lower profile is preferred. The dual rib design increases stiffness and improves installation. Stakes are a good choice for survey and boundary identification where increased flexibility is not a concern. The design provides for easy center drilling and attachment of optical signs and hardware. Made of glass reinforced polyester composite, our markers are available in standard lengths from 62 to 90 inches and in a range of colors including White, Orange, Yellow, Blue, Green, Red and Brown.
