What is the minimum distance at which markings must be provided throughout the piping run?

Markings on piping runs for non-flammable compressed gases are crucial for ensuring safety and compliance with regulations. The minimum distance of 20 feet for these markings is established to ensure that individuals can easily identify the contents of the piping from a safe distance. This visibility is essential in emergency situations or when maintenance is required, as it helps to minimize the risk of accidents or misuse of the system.

Markings placed at this interval promote clear identification of the gas type and associated hazards, allowing personnel to respond appropriately. A standard of 20 feet balances the need for visibility with logistical considerations, ensuring that marks are frequent enough to be noted by anyone in the vicinity. Compliance with this distance enhances safety protocols and supports better operational practices within environments dealing with non-flammable compressed gases.
