What is the maximum allowable percentage of flammable gas in a mixture to consider it non-ignitable?

• A. 5 percent
• B. 10 percent
• C. 13 percent
• D. 20 percent

Answer: (C)

The maximum allowable percentage of flammable gas in a mixture to be considered non-ignitable is 13 percent. This threshold is based on safety regulations and standards that specify how gas mixtures should be classified to prevent combustion hazards. When the flammable gas concentration remains below this percentage, the mixture is deemed to have an insufficient amount of flammable material to ignite under normal conditions, thereby reducing the risk of fire or explosion. Understanding this concept is crucial, especially for handling and transporting compressed gases safely. Regulatory bodies set these limits to ensure that any environment or process that involves such gas mixtures adheres to safety protocols, thereby protecting personnel and property from potential hazards associated with flammable gases.
