Proper placement helps prevent severe injury, ensures compliance, and supports safe maintenance procedures in commercial, industrial, and construction environments.

Materials: Printed Adhesive Vinyl; Gloss Laminate

What This Sign is For: A Danger Arc Flash sign warns workers and personnel of the risk of an arc flash, a hazardous electrical event that can cause severe burns, injury, or death. These signs identify areas where energized electrical equipment presents a danger and where specialized PPE and safety procedures are required. 

Legal Requirement Explained: Arc flash warning labels are required under OSHA 29 CFR 1910.335 and NFPA 70E (Standard for Electrical Safety in the Workplace). These regulations mandate that electrical equipment likely to require examination, adjustment, servicing, or maintenance while energized must be clearly marked to warn qualified personnel of potential arc flash hazards. 

Who is Required to Post This Sign: 
- Commercial and industrial buildings with electrical systems
- Construction sites with temporary or permanent electrical installations
- Facilities with switchgear, panelboards, motor control centers, or similar equipment
- Property owners, employers, and facility managers responsible for worker safety
- Any workplace where employees may interact with energized electrical equipment

Where We Recommend This Sign Be Posted: 
- Directly on or immediately adjacent to electrical equipment
- On electrical panels, switchboards, disconnects, and control cabinets
- At locations where maintenance or service work may expose workers to energized components
- In a position that is clearly visible before accessing or opening the equipment

Unacceptable Locations to Post This Sign: 
- On walls far from the actual hazard
- Inside panels or equipment where it is only visible after opening
- Behind doors, obstructions, or stored materials
- In low-visibility or poorly lit areas
- On temporary or removable surfaces where the sign may be lost or damaged

Recommended Height / Installation Requirements: 
- Install at eye level (typically 48”–60” above finished floor) for immediate visibility
- Must be permanently affixed to equipment or adjacent surfaces
- Use durable, weather-resistant materials where applicable
- Ensure high contrast and legibility in accordance with OSHA visibility standards
- Placement must allow the sign to be seen before exposure to the hazard occurs
