Tunnel Display Signs

Tunnel-related signs are safety signs used at work sites for tunnel excavation and maintenance. A management board for work inside the tunnel and a list for confirming who entered the tunnel are necessary to manage and understand the work status outside the tunnel. Signs indicating the oxygen status in the mine and no entry during lack of oxygen are also very important for ensuring safety. The signs used inside the tunnel indicate the distance from the well entrance and evacuation sites. If gas pipes, water pipes, etc. are buried in the ground at the work site, signboards to display the buried objects and sheets laid between the ground surface and the buried objects are useful. Let's use it to effectively call attention and prevent crushing accidents.
