Preventing Injury and Damage Through Effective Labeling


The vast majority of machinery manufactured today presents potential electrical hazards. Electrocution, electric shock, burns, fire, arc flash explosion, and equipment damage due to improper grounding or electrostatic discharge are all real risks. Clarion Safety’s electrical hazard labels help mitigate these risks and are critical to the safe use and maintenance of equipment in operation today.

Designing Electrical Labels for Real-World Performance


Effective Hazard Communication for All Users

Your labeling strategy must account for a diverse audience - from trained electricians and technicians to untrained personnel who may come into contact with equipment. Unlike visible mechanical hazards, electrical risks are often hidden. Clarion's labels help ensure those hazards are clearly identified and understood by all users, reducing the likelihood of accidents.

Graphical Symbols for Universal Understanding

Most Clarion Safety electrical hazard labels use one or more graphical symbols to reinforce the message: hazardous voltage, lockout/tagout instructions, arc flash warnings, electrostatic discharge, or do not touch. These symbols help bridge language barriers and reinforce quick recognition in high-risk situations.

Electrical Hazard Labels Designed for Compliance and Liability Protection

Today’s standards require more than just a "HIGH VOLTAGE" warning. Clarion’s labels provide a complete message - identifying the hazard, explaining the consequence of interaction, and specifying avoidance procedures. Our labels are designed to ANSI and ISO standards, support OSHA compliance, and help mitigate liability by delivering accurate, context-rich warnings.

Labeling Solutions for Complex Electrical Environments

We offer a full suite of electrical hazard labels designed for complex industrial environments. This includes solutions for dual power sources, emergency shutdown procedures, grounding, arc flash zones, and more. Labels are available across all safety signal word levels (Caution, Warning, Danger, Notice) and are built for durability in indoor and outdoor conditions. Organized by function and use case, they’re easy to search and deploy across your operation.

  • Arc Flash Labels: Arc flash labels identify hazards and inform personnel about safety issues, helping to reduce the risk of injury or death for those who work on or near energized electrical equipment. These labels comply with NFPA 70E, NEC, and OSHA regulations, and feature ISO-standardized arc flash symbols.
  • Electrical Disconnect Labels: Electrical disconnect safety labels inform users to disconnect power before servicing equipment. They align with NEC requirements and are available in various symbol and text combinations.
  • Electrical Grounding Labels: Grounding labels promote proper grounding to prevent electric shock and fire. These are critical in installations with leakage current risks and come in multiple symbol formats.
  • Electrical Lockout Tagout Labels: Lockout tagout (LOTO) labels support OSHA compliance to prevent hazardous energy accidents. These labels cover procedures and are available in several design formats.
  • Electrostatic Discharge Labels: ESD labels indicate areas and components sensitive to electrostatic discharge. Designed for IEC compliance, they help protect electronics from damage.
  • General Electrical Hazard Labels: General electrical hazard labels provide broad warnings without specifying avoidance procedures. Ideal for environments with undefined electrical risks.
  • Multiple Sources of Power Labels: Labels used to indicate equipment powered by multiple energy sources, ensuring full isolation during maintenance to prevent accidents.
  • High Voltage and Fuse Labels: Labels that identify high voltage areas and fuse locations, supporting safety and maintenance visibility for hazardous zones.
  • Specific Voltage and Fuse Labels: Clarion Safety's labels for specific voltages and fuses help identify power ratings and compatible fuse types to prevent overheating and fire.
  • Specific Voltage Labels: Specific voltage labels help identify product voltage settings to ensure safe connections and compliance with operational requirements.

Frequently Asked Questions About Electrical Hazard Labels

What are electrical hazard labels used for?

Electrical hazard labels are used to warn personnel of potential risks like electric shock, arc flash, high voltage, electrostatic discharge, and fire. These labels help prevent injury and equipment damage by communicating dangers clearly, often with a combination of symbols and text.

Why are electrical safety labels important for compliance?

Electrical safety labels help support compliance with key regulations and standards including OSHA, ANSI Z535.4, and ISO 3864-2. Today’s standards require more than generic warnings; they require hazard identification, consequences of interaction, and instructions for safe avoidance. Using compliant labels can also reduce liability exposure in the event of an incident.

How do Clarion Safety’s electrical labels differ from generic “High Voltage” stickers?

Clarion Safety’s labels go beyond basic warnings. They are designed with ANSI/ISO-compliant layouts, clear safety signal words, and symbols that support fast recognition. Each label communicates the specific electrical hazard, its potential consequence (e.g., electrocution, arc flash), and instructions for avoiding it, helping to keep both trained technicians and untrained personnel safe.

What types of electrical hazards do these labels cover?

Clarion Safety labels cover a wide range of hazards including:

  • High voltage/electrocution
  • Arc flash explosion zones
  • Static discharge/Electrostatic-sensitive devices (ESD)
  • Do not touch/energized parts
  • Dual power sources
  • Lockout/Tagout (LOTO) requirements
  • Improper grounding risks
These labels are designed for real-world electrical environments, including industrial machinery, control panels, and power systems.

Can electrical hazard labels be customized?

Yes. Clarion Safety offers custom label design services to meet your specific electrical safety needs. You can customize label text, symbols, language, material, and format. This ensures alignment with your internal safety protocols and equipment-specific requirements.

Are your labels suitable for harsh environments?

Absolutely. Our electrical hazard labels are manufactured using high-durability materials suitable for indoor and outdoor use, including exposure to moisture, abrasion, chemicals, and UV light. They are ideal for demanding applications in industrial, energy, utility, and manufacturing environments.

How do graphical symbols improve electrical safety communication?

Most electrical hazards are not visible at a glance—unlike many mechanical dangers. That’s why Clarion’s labels use standardized graphical safety symbols for hazards like high voltage, arc flash, or static sensitivity. These visuals promote fast, universal understanding, helping reduce risk across language barriers and for personnel with varying levels of training.

What are the best practices for placing electrical hazard labels?

Electrical safety labels should be placed:

  • Directly on or near the hazardous electrical component
  • On access panels, control boxes, and enclosures
  • In visible locations before a worker could interact with the hazard
  • According to LOTO and arc flash boundary procedures
Proper placement ensures that labels serve as a last line of defense before exposure, reinforcing training and hazard awareness.
