“When venting gas, protect your ears from noise.”

The warning refers to the high noise levels that can occur when pressurised gas is released or vented from industrial equipment.

This type of sign was used in Soviet industrial facilities, technical installations and areas involving pressurised gas systems.

Made of metal with a yellow background and large red Cyrillic lettering.

Approximate dimensions: 43 × 34 cm.

An unusual and visually striking piece of Soviet industrial and occupational safety history, interesting for collectors of USSR memorabilia, vintage factory signs and industrial interiors.

Please examine all photographs carefully, as they form an integral part of the description.

A wonderfully creative display piece — this sign would be absolutely perfect hung in a WC or nearby, adding a touch of humor and character to the interior :) :) :)
