Danger OSHA Sign: Danger Men Working Above Sign

Danger Men Working Above OSHA Sign — Clear Overhead Hazard Warning for Active Job Sites

The Danger Men Working Above Sign is a compliant OSHA-format safety sign designed to alert workers and passersby to overhead personnel hazards on active construction and industrial job sites. Printed in high-visibility black and red on a horizontal layout, this sign communicates a critical danger condition at a glance. It is available in multiple sizes and substrate materials to suit permanent installations, temporary postings, or harsh outdoor environments. Contractors, site supervisors, and safety managers will find this sign suitable for framing, scaffolding, elevated work platforms, and any area where overhead work is in progress.

Technical Specifications

This sign is offered across a broader size and material range than many standard safety signs, allowing contractors to select the exact substrate — from flexible vinyl labels for temporary use to heavy-duty 40 mil aluminum for permanent installation — that matches their site conditions and compliance requirements. The horizontal format and OSHA-standard red-and-black color scheme ensure immediate recognition by workers familiar with ANSI/OSHA danger signage conventions.

Key Features & Benefits

Multiple Substrate Options

Available in six distinct materials including 3M Engineer Grade Aluminum, 40 mil Aluminum, Plastic, Laminated Plastic Labels, 3M Engineer Grade Labels, and 3M Vinyl Labels. This allows site managers to match the sign material to the environment — rigid aluminum for permanent outdoor posts, vinyl or label stock for temporary or surface-mounted applications.

Four Size Options

Offered in 3.5" x 5", 5" x 7", 7" x 10", and 10" x 14" to accommodate varying viewing distances and posting locations. Larger formats are appropriate for high-traffic areas or elevated mounting where legibility at distance is critical.

OSHA Danger Format

The black and red color scheme follows OSHA danger signal word conventions, immediately communicating a serious hazard condition to workers on site. Consistent use of standardized signage reduces confusion and supports site safety compliance.

Horizontal Layout

The horizontal orientation suits standard sign frames, barricade mounting, and fence or wall posting common on construction sites. This format maximizes text legibility within a compact footprint.

Common Applications

Scaffolding and Elevated Work Platforms

Post at ground level below active scaffolding or elevated platforms to warn workers and pedestrians of overhead personnel hazards.

Construction Site Perimeters

Mount on fencing, barricades, or temporary barriers surrounding areas where overhead work is ongoing to restrict unauthorized access.

Building Renovation and Demolition Zones

Use during interior or exterior renovation projects where workers on upper floors or rooftops create falling-object and overhead hazard risks for those below.

Industrial Facilities

Install in warehouses, manufacturing plants, or maintenance areas where overhead work such as crane operations, rigging, or structural repairs is performed.
