Danger OSHA Sign: High Voltage — Clear Hazard Communication for Electrical Areas
The Danger High Voltage OSHA sign (Part# LS-10951) is a compliant safety sign designed to warn workers and site personnel of high-voltage electrical hazards. Intended for contractors, electricians, facility managers, and trades professionals, this sign is suited for placement on electrical panels, transformer enclosures, restricted access areas, and any location where high-voltage equipment is present. Available in multiple sizes and substrate materials, it provides flexible deployment across job sites, industrial facilities, and permanent installations.

This sign is offered in a broader range of substrate materials than many standard safety signs, allowing contractors to select the appropriate durability level for indoor, outdoor, temporary, or permanent applications. The availability of 40 mil aluminum and 3M Engineer Grade options ensures the sign can withstand demanding job site and industrial environments where lesser materials would degrade.
Key Features & Benefits
Multiple Substrate Options
Choosing the right material for the environment is critical for sign longevity and compliance. Options range from economical laminated plastic labels for short-term use to heavy-duty 40 mil aluminum for permanent outdoor or industrial installations.
3M Engineer Grade Materials Available
3M Engineer Grade labels and aluminum substrates provide enhanced durability and print quality compared to standard materials. This is particularly valuable in high-traffic or harsh environments where sign legibility must be maintained over time.
Multiple Size Options
With four available sizes — from 3.5" x 5" up to 10" x 14" — contractors can match the sign to the viewing distance and mounting location requirements of the specific hazard area.
Red and Black OSHA Danger Color Scheme
The red and black color scheme follows OSHA Danger signal word conventions, immediately communicating the highest level of hazard to workers. Consistent use of standardized color coding reduces the risk of misinterpretation on busy job sites.
Horizontal Format
The horizontal orientation is well-suited for mounting on panels, doors, enclosures, and barriers where width is available, maximizing legibility at a glance.
Common Applications
Electrical Panel Enclosures
Mount directly on electrical panel doors or covers to warn personnel of high-voltage hazards before opening or servicing.
Transformer and Switchgear Areas
Identify restricted zones around transformers, switchgear, and high-voltage distribution equipment on commercial and industrial job sites.
Restricted Access Rooms
Post on doors or barriers leading to electrical rooms or vaults to prevent unauthorized entry by non-qualified personnel.
Construction Site Temporary Power
Apply to temporary power distribution boxes and service entrances during active construction to alert all trades working in the area.
