DANGER Underground Mining Drill Sign – Noxious Fumes – 8x12 Aluminum

Underground drilling and jackhammer work combines noise, vibration, and exhaust in some of the tightest spaces on a job. Everyone down there needs to know when respirators are required.

The CGAP Safety “Danger – Underground Mining Drill – Jackhammer & Noxious Fumes – Respirator Required” sign is designed for mines, tunnels, and heavy civil projects that run drilling operations in confined areas. The bold red DANGER header and straightforward text warn crews that drilling and jackhammer work may generate noxious fumes and that respiratory protection is required in the designated zone.

This 8 x 12 inch sign is manufactured from rust-resistant aluminum to stand up to moisture, dust, and rough handling underground. The high-contrast red, black, and white OSHA-style layout is easy to pick out under low lighting on bulkheads, equipment doors, manways, and access points.

Use this sign as part of your broader ventilation and respiratory protection program to help communicate when additional PPE is required around drilling operations in tunnels and headings.

Important: This product is a warning sign only and does not replace gas monitoring, ventilation controls, PPE selection, or regulatory guidance. Always follow applicable mining and construction safety standards, site procedures, and manufacturer instructions.
