NFPA 704 CNG Placard Sign on Fence - West Jordan, Utah

The NFPA (National Fire Protection Association) rating sign for CNG (Compressed Natural Gas) follows the NFPA 704 Hazard Diamond system, which provides crucial safety information for emergency responders. This diamond-shaped sign is divided into four colored sections, each indicating a different hazard category:

  1. Blue (Health Hazard) – Typically rated 1 for CNG, indicating a slight hazard under normal conditions, but inhalation of high concentrations can cause dizziness or asphyxiation.
  2. Red (Flammability Hazard) – Rated 4, the highest level, as CNG is extremely flammable and can ignite easily in air.
  3. Yellow (Instability/Reactivity Hazard) – Rated 0, meaning CNG is stable under normal conditions and does not readily react with other chemicals.
  4. White (Special Hazard) – Usually left blank for CNG, as it does not have significant corrosive or radiation-related dangers.

These signs are commonly displayed on CNG storage tanks, fueling stations, and transport vehicles to warn of the gas’s high flammability and ensure proper handling during emergencies. Proper ventilation, leak detection, and adherence to safety protocols are essential when working with or around CNG.

Compressed Natural Gas Pump - Salt Lake - Utah


A compressed natural gas (CNG) gas pump, located in the Salt Lake Valley of northern Utah, along the Wasatch Front.

A natural gas fueling station is specifically designed to dispense Compressed Natural Gas (CNG), a cleaner and more environmentally friendly alternative to gasoline or diesel. These pumps are commonly found at public refueling stations, fleet depots, or private facilities catering to vehicles powered by natural gas, such as buses, trucks, and passenger cars. CNG is stored under high pressure in specially designed tanks and is dispensed through nozzles that securely connect to a vehicle’s fueling port. Modern CNG pumps are equipped with safety features such as pressure regulators, automatic shutoff systems, and monitoring devices to ensure efficient and secure fueling.

CNG gas pumps support efforts to reduce greenhouse gas emissions and improve air quality by providing a low-emission fuel option. Vehicles running on CNG produce significantly less carbon dioxide, nitrogen oxides, and particulate matter compared to traditional fuels. Additionally, CNG is often more cost-effective, providing savings for both individual drivers and large fleets. These pumps play a crucial role in expanding the adoption of natural gas vehicles (NGVs) and promoting sustainable transportation solutions.

CNG Gas Station Price Sign - Utah

A CNG station (Compressed Natural Gas station) is a facility where compressed natural gas (CNG) is stored, distributed, and dispensed to vehicles that run on CNG. CNG is natural gas that has been compressed to a high pressure (typically around 3,000–3,600 psi) to reduce its volume, making it suitable for use in vehicles as an alternative to gasoline or diesel.

CNG is considered a cleaner fuel compared to gasoline and diesel, producing lower levels of carbon dioxide (CO2), nitrogen oxides (NOx), and particulate matter.

CNG stations are often located in urban areas, near highways, or in industrial regions, providing accessible refueling points for vehicles running on compressed natural gas.
