Notice OSHA Sign: Employee Entrance Only

OSHA Employee Entrance Only Sign – Clear Access Control for Worksites

The Notice OSHA Employee Entrance Only sign is a compliant, professionally produced safety sign designed to restrict and direct personnel access at construction sites, industrial facilities, and commercial job sites. Formatted in the standard OSHA Notice color scheme of blue and black, it communicates access restrictions clearly to workers, subcontractors, and visitors. Available in multiple sizes and substrate materials, this sign is suited for both temporary and permanent installation across a wide range of environments.

Technical Specifications

Unlike generic printed signs, this product is available in heavy-duty 40 mil aluminum and 3M Engineer Grade substrates, offering durability and visibility levels appropriate for demanding job site conditions. The range of sizes and materials allows contractors to select the right combination for indoor, outdoor, temporary, or permanent applications without sourcing from multiple vendors.

Key Features & Benefits

OSHA Notice Color Scheme

The blue and black Notice format follows OSHA's established color-coding system for informational signage. This ensures workers and inspectors immediately recognize the sign's intent without ambiguity on a busy job site.

Multiple Substrate Options

Available in 3M Engineer Grade Labels, Laminated Plastic Labels, 3M Engineer Grade Aluminum, Plastic, and 40 mil Aluminum, contractors can match the material to the installation environment. Heavy-gauge aluminum is ideal for permanent outdoor mounting, while label formats work well for temporary barriers or equipment.

Three Size Options

Offered in 5" x 7", 7" x 10", and 10" x 14", the sign can be scaled to the viewing distance and mounting location required. Larger formats are appropriate for high-traffic entry points, while smaller sizes suit doorways or equipment panels.

Horizontal Format

The horizontal orientation maximizes legibility across standard door frames, gates, and barrier panels. This layout is well-suited to the typical proportions of entrance signage mounting locations found on construction and industrial sites.

Common Applications
