FDNY CoF G-71 Medical Gas Supervision Practice Exam 2025 – Complete Prep Guide

Question: 1 / 400

Which statement about oxidizing gases is true?

They are safe under all conditions

They can be used without any precautions

They can support combustion

The statement that oxidizing gases can support combustion is accurate because oxidizing gases are substances that readily yield oxygen or other oxidizing substances, thereby enhancing the combustion of other materials. This characteristic makes them highly reactive and potentially hazardous in the presence of flammable materials. For example, oxygen, which is a common oxidizer, accelerates the burning of fuels, increasing the risk of fires and explosions if not handled carefully.

Understanding the properties of oxidizing gases is crucial for ensuring safety in environments where these gases are utilized, especially in medical settings where piped non-flammable medical gases are used. The other statements inaccurately suggest either a lack of risk or the necessity of precautions when working with oxidizing gases, which does not align with safety protocols and best practices in handling such materials.
