Cylinders designed for low pressure gas are built according to which standards?

1. EPA

2. DOT

3. OSHA

4. ANSI

The correct answer is: DOT

Cylinders designed for low pressure gas are regulated by the Department of Transportation (DOT) standards. The DOT has established guidelines and specifications that ensure the safe design, construction, testing, and maintenance of pressure vessels, including low-pressure cylinders. These standards are critical in ensuring that the cylinders can withstand the pressure of the gas they hold without risking failure or leaks, which could pose safety hazards. The other organizations mentioned have their own areas of focus. The Environmental Protection Agency (EPA) deals with environmental protection regulations but does not focus specifically on the engineering standards for pressure cylinders. The Occupational Safety and Health Administration (OSHA) sets and enforces workplace safety standards, which may touch on the use of cylinders but does not dictate their design specifications. The American National Standards Institute (ANSI) develops standards for a wide range of products and services, but in the case of low-pressure gas cylinders, the DOT standards take precedence. Therefore, when it comes to the design of cylinders for low-pressure gas, DOT standards are the relevant and authoritative guidelines.
