Medical Pipe Markers on a roll are a practical, economical marking system featuring bold characters. Each marker is laminated and color coded to meet CGA C-9 Section 4.1 (Compressed Gas Association Standard) used for marking of compressed gas intended for medical use. Clearly marked pipes will inform staff and visitor’s what is in the piping system at your facility. A hospital, clinic or other health care facilities is no place for mistakes. Avoid Accidents; using pipe markers is a step in the right direction to maintain a perfect safety record. Each marker shows legend and flow direction designed to be read from any direction or position. Each marker wraps completely around pipes up to 1” diameter providing 360° visibility to allow identification of pipe contents at a glance.
