Energy source identification labels help factory and facility personnel match equipment control points to the identifiers in their energy-control procedures. Often searched for as “energy source tags” or “energy source ID tags,” the products below are adhesive identification stickers, not hanging tags, locks or personal lockout/tagout devices.
Use this guide to compare source types, numbered and custom identifiers, and related OSHA references. A source marker does not isolate energy, verify equipment condition or make machinery safe to service.
These labels support identification of energy-control points on factory and facility machinery. Examples might include a conveyor’s electrical disconnect, a production machine’s compressed-air shutoff or a hydraulic system’s isolation point. The correct label and identifier depend on the actual equipment and its documented energy-control procedure, not just the machine’s name or model.
OSHA 1910.147 addresses servicing and maintenance where unexpected energization, startup or release of stored energy could injure employees. It is not a blanket requirement for every machine or every task. Check the standard’s scope and exceptions for the work being performed; identifying an energy source does not establish which control measures are required.
One machine may have several energy sources and control points. An electrical disconnect alone does not establish that hydraulic pressure, compressed air, stored motion or other hazardous energy has been controlled. These stickers identify points; they do not isolate energy or verify a safe condition.
Each listed design measures 3 inches wide × 1½ inches tall. Select identifiers that match the actual equipment and the facility’s documented system. Choosing one numbered option does not supply a complete numbered set. Custom identifiers are printed for the order, not supplied as blank write-in fields.
For the pneumatic, steam, gas, valve, water-valve and kinetic custom options, enter the full requested identifiers in the shopping-cart Notes as directed on the product page. Check the selected listing’s current options and instructions before ordering.
These references explain the relationship between identification and hazardous-energy control. They do not establish a requirement to buy these particular stickers or use a universal letter, number or color scheme. Confirm the standard’s scope, exceptions and applicability to the actual servicing activity.
For covered activities, this provision addresses developing, documenting and using energy-control procedures, with a limited documentation exception subject to all the listed conditions. Paragraph (c)(4)(ii) addresses specific procedural steps for shutdown, isolation, blocking/securing equipment, device responsibilities and testing the effectiveness of energy-control measures.
Matching a source identifier to the equipment procedure can help personnel recognize the corresponding point. The number alone is not the procedure, isolation instruction or verification.
Read the complete OSHA 1910.147 standard, including (c)(4).
This provision addresses authorized employees affixing lockout or tagout devices to energy-isolating devices. It distinguishes holding devices in a safe/off position from the prohibited-operation message provided by tagout devices. The adhesive source-identification labels listed above do neither job and must not be treated as personal lockout tags.
Read OSHA 1910.147(d)(4) in the complete standard.
OSHA’s hazardous-energy publication discusses controlling stored energy and verifying isolation/de-energization. Its typical minimal procedure also identifies examples such as capacitors, springs, elevated components, rotating flywheels and hydraulic, air, gas, steam or water pressure. These references are not a substitute for a procedure developed for the actual equipment.
Read OSHA’s Control of Hazardous Energy publication; read 1910.147 Appendix A, Typical Minimal Lockout Procedures.
They identify corresponding disconnects, valves or other control points within a facility’s system. For example, an identifier such as E-1 can correspond to the same point identified in the equipment’s energy-control procedure. The responsible person must confirm that association; the label does not determine which point controls which hazard.
No. These are fixed adhesive identification markers. They are not personal tagout devices, locks, isolation devices or evidence that energy has been controlled. Do not substitute a numbered source sticker for required energy-control measures.
The linked range includes electrical, hydraulic, pneumatic, steam, gas and kinetic designs, plus valve and water-valve identifiers. The nine product designs are not nine distinct energy categories: hydraulic has two designs, and valve identifiers identify components. This range is not an exhaustive list of every hazardous energy source.
Use the identifier established for the specific equipment control point in your facility’s system. Do not select an arbitrary number or infer voltage, pressure, temperature or capacity from it. Custom examples such as E-1-1 or H-A-1 illustrate formatting possibilities, not required numbering conventions.
No. The number option specifies the identifier to print, not a complete sequential set. Check the listing and order details for the quantity and individual identifiers required.
They are separate designs that both use H-number identifiers. Match the design and numbering to your facility’s equipment-identification system. Neither color proves that pressure is relieved or that a valve is isolated; this guide does not assign a universal regulatory meaning to the colors.
No. V- and W-number labels identify the valve; they do not indicate valve position, locking status, flow direction or permission to operate it. A faucet symbol does not establish fluid contents or potable-water suitability.
No. Gauge illustrations on pneumatic, steam and gas designs are printed graphics. They do not measure pressure or verify isolation.
Follow the equipment procedure and manufacturer/site instructions. As general guidance, use a suitable fixed surface at or beside the corresponding point, readable to personnel identifying it. Have the person responsible for the energy-control procedure confirm the identifier and location. Keep equipment identification, control positions, warnings, guards and service access clear.
Do not place labels on moving gears or assume that a steam label is suitable for direct application to hot pipework. Verify actual temperature, moisture and surface conditions for the product. These are adhesive labels, not metal valve tags or hanging identification tags.
No. Labels support identification; they do not supply an energy-control program, perform isolation, provide training or verify a safe condition. Use the complete applicable requirements and equipment-specific procedures rather than treating a label purchase as corrective action by itself.
