The ACCUFORMNMC W9AB is a rectangular aluminum safety sign printed with the Warning - Authorized Personnel Only legend. Constructed from 0.04-inch aluminum with a Sign Muscle coating, it resists chemicals, UV exposure, and graffiti - making it suitable for demanding industrial and commercial environments. The sign displays a single English-language message in black and orange on a standard warning header layout. It comes pre-drilled for straightforward wall mounting. Licensed contractors, facility maintenance personnel, and safety compliance officers typically source and install this type of signage as part of OSHA-aligned hazard communication programs.
This sign is intended for wall-mounted installation in areas where access must be restricted to authorized personnel. Typical applications include electrical rooms, mechanical rooms, rooftop equipment areas, utility corridors, and equipment yards. The single-viewing-point, message-only format keeps the communication clear and unambiguous. The 10-inch height provides strong visibility at standard eye level in hallways and doorways.
Designed for general wall-mount installation in industrial, commercial, and institutional facilities requiring access restriction signage.
Installation is performed by maintenance personnel or contractors using standard fasteners through the pre-drilled holes. Confirm the mounting surface material before selecting fastener type - concrete, drywall, and steel substrates each require appropriate anchors. Position the sign at a height clearly visible to approaching personnel, typically between 48 and 60 inches from finished floor per common facility standards. No special tools or trade licensing are required for sign installation.
