NFPA-99 Practice Exam

How should station outlets/inlets be identified for the specific gas?

1. By chemical symbol.

2. By name.

3. By name or chemical symbol.

4. By piping type.

The correct answer is: By name or chemical symbol.

Identifying station outlets and inlets for specific gases is crucial for ensuring safety and clarity in medical and industrial settings. The correct approach is to label these outlets and inlets by either the chemical name or the chemical symbol of the gas involved. This dual method of identification helps prevent confusion and errors during gas handling, especially in environments where multiple gases may be in use. Using the chemical name offers a clear and comprehensive understanding of the gas's identity, while the chemical symbol provides a concise, universally recognized shorthand. This is particularly important in emergency situations or when staff are unfamiliar with all potential gas types involved. Relying solely on one form of identification could lead to misinterpretation or mishaps, especially if similar-looking names or symbols are present. Other methods of identification, such as designating by piping type, may not provide the same level of clarity regarding the specific gas being utilized. Thus, utilizing both the name and symbol creates a safer and more efficient working environment.
