Pipe Markers Compliance – Resource Bulletin Pipe Marker Labels Signs Overview: Hazardous materials and chemicals are widely transported through piping systems in industrial, commercial, and governmental situations. Though these piping systems may be constructed to strict design standards, their operation and maintenance can be inherently hazardous to workers, the general public, and the environment. Mistakes made in turning on valves or disconnecting pipes at the wrong time or place can result in serious injuries or damage to property. [1] In order to promote greater safety, lessen the chances of error, confusion, or inaction, especially in times of emergency, a uniform system for the identification of piping contents is important to warn personnel when the piping contents are inherently hazardous. [1] Though OSHA regulates safety standards for all piping systems, it relies on a number of identification standards, each of which addresses the labeling of a particular type of piping.
