Definition and Purpose
NFPA 71, titled "Standard for the Installation of Gas and Vapor Systems," provides guidelines for the safe installation, operation, and maintenance of non-electrical gas and vapor systems. These systems include pipelines, tanks, valves, and associated equipment that handle flammable or combustible gases and vapors in industrial, commercial, and institutional environments.
The primary purpose of NFPA 71 is to:
- Prevent fires, explosions, and leaks.
- Provide clear procedures for safe installation and operation.
- Ensure personnel safety.
- Protect property and the environment from hazards related to gas and vapor systems.
Scope of NFPA 71
NFPA 71 covers a broad range of systems, including:
- Gas and vapor piping systems
- Storage tanks for gases and vapors
- Valves, regulators, and fittings
- Ventilation and combustion systems linked to gas/vapor systems
- Installation practices for both new and existing systems
- Inspection, testing, and maintenance procedures
The standard applies to systems used in various sectors such as manufacturing, healthcare, laboratories, and commercial buildings where gases and vapors are utilized.
