When storing LP-Gas and compressed gases in the same area, what must be marked according to NFPA #58?

The requirement to mark the containers themselves is essential for safety and regulatory compliance when storing LP-Gas and compressed gases in the same area, as stated in NFPA #58. This marking serves several critical purposes: it provides clear identification of the contents, which is vital in emergencies where first responders need to know what types of gases are present, thus allowing them to take appropriate safety measures. Proper labeling also helps prevent the accidental mixing of incompatible gases, which can pose significant safety risks.

Additionally, marking the containers aids in compliance with safety regulations and can assist in the management of inventory and maintenance practices. This practice enhances overall safety by ensuring that anyone who comes into contact with these containers is aware of their contents, reducing the risks of accidental exposure or mishandling.
