DANGER Microwave Radiation Hazard Sign – Avoid Exposure – 8x12 Aluminum

Microwave transmitter areas can expose personnel to hazardous RF energy when equipment is energized. This sign helps reduce risk by clearly identifying the transmitter area and setting a strict access-control rule that supports safe site procedures.

Post it anywhere personnel could accidentally enter or linger near energized RF equipment, especially where access needs to be controlled during operation.

Common placements

• Microwave transmitter shelters and equipment huts
• RF equipment rooms and controlled access corridors
• Microwave backhaul dish sites and fenced compounds
• Broadcast transmitter facilities and comms infrastructure
• RF test areas and restricted utility spaces

Construction features

• 8x12 aluminum sign for industrial posting
• Rust-resistant aluminum for long service life
• High-contrast layout for quick readability
• Designed for frequent viewing in facility environments

Operational note: Post at entry points and along approaches to the transmitter area where someone could unknowingly enter while equipment is energized.

• Restricts access to RF zones: Clearly marks microwave transmitter areas to reduce exposure risk and discourage unauthorized entry.
• Fast, enforceable wording: “KEEP OUT WHEN ENERGIZED” gives an unambiguous instruction that workers and visitors understand instantly.
• Built for facility environments: 8x12 rust-resistant aluminum sign made for industrial posting in equipment and infrastructure areas.
• Ideal for niche placements: Great for transmitter shelters, microwave backhaul sites, RF equipment rooms, broadcast facilities, and controlled access areas.
