Danger Electrical Vault Sign – Confined Space Permit Required for Entry, 8x12 Rust-Resistant Aluminum Utility Safety Sign by CGAP Safety

Electrical vaults are not storage closets and they are not “quick look” spaces. They are typically underground or partially enclosed areas with restricted entry, limited escape routes, and the potential for multiple overlapping hazards depending on site conditions and equipment configuration.

The CGAP Safety “Danger – Electrical Vault – Confined Space – Permit Required for Entry” sign is designed to communicate one simple operational reality: this vault is a controlled space, and entry must be managed through a permit process. The bold red DANGER header signals severity at a glance, while the confined space and permit language helps align expectations for contractors, maintenance crews, and anyone working near vault access points.

This sign is sized at 8 x 12 inches for strong visibility without being oversized, making it a practical fit on vault doors, fence lines, walls, posts, equipment rooms, and near underground access hatches. The high-contrast red, black, and white OSHA-style layout stays legible in busy industrial environments where quick recognition matters.

Manufactured from rust-resistant aluminum, it is built for real-world placement and long-term exposure, holding up better than paper notices, thin plastic markers, and temporary labels that fade, crack, or peel.

Use this sign as part of your confined space and electrical safety controls to help reduce unauthorized entry, reinforce site rules, and support consistent jobsite communication around electrical vault access.

CGAP Safety is an American safety manufacturer dedicated to straightforward, durable signage that helps organizations see the gap and close the gap between written procedures and day-to-day field execution.

Important: This sign is a warning tool only and does not replace required training, permits, atmospheric testing, lockout/tagout, guarding, PPE, rescue planning, or applicable standards and local requirements. Always follow your facility’s written confined space and electrical safety procedures.
