Warning - Under Test - Do Not Touch - Safety Signs by Caledonia Signs

This multi-message sign has been designed to alert personnel that equipment, machinery, or systems are currently undergoing testing and should not be touched or operated. By clearly displaying this sign, organisations prevent accidental interference, which could cause equipment damage, compromise test results, or lead to personal injury. It serves as a visual barrier to ensure that only authorised personnel handle the equipment during critical procedures.

A primary application is in industrial, manufacturing, and laboratory settings where machinery, electrical panels, or experimental setups are being tested. During these periods, equipment may be live, unstable, or in a non-standard operating state, making it hazardous for untrained personnel to interact with it. The sign helps maintain safety and process integrity.

It is also used in research and development facilities, quality control labs, and technical service areas. By placing the sign on or near test equipment, devices, or vehicles, it informs engineers, technicians, and visitors to stay clear until testing is completed, reducing the risk of accidental injury, equipment malfunction, or data contamination.
