Final answer:
The use of compressed natural gas (CNG) must comply with safety regulations to prevent accidents. While CNG does not require a special license for consumers, professionals may need training and certifications. It can be used in urban areas with appropriate safety precautions.
Step-by-step explanation:
The handling and use of compressed natural gas (CNG) must comply with various safety regulations. These regulations are put in place to prevent accidents and ensure safe storage, transportation, and usage. In the context of CNG and other gases like propane, which is often used in remote locations where natural gas pipelines are not available, safety is paramount due to the flammable and hazardous nature of these substances.
When using CNG, specific training and adherence to safety protocols are necessary. For instance, CNG should not be used or stored indoors due to the risk of gas accumulation and potential asphyxiation or explosion. CNG is a cleaner fuel alternative and can be used in urban areas if all safety measures are strictly followed, contrary to the notion that its use is prohibited in urban settings.
The use of CNG, similar to other compressed gases such as oxygen in hospitals or propane for barbeque grills, does not require a special license for general consumers; however, professionals who install, service, or transport CNG may need specialized training and certifications.
