What is the autoignition temperature (AIT) of acetylene?

The autoignition temperature (AIT) of acetylene is indeed approximately 325 degrees Celsius. This temperature is significant because it represents the lowest temperature at which acetylene can self-ignite without any external flame or spark. Understanding the AIT of a substance is crucial in fire hazard assessments, as it helps in determining the safe storage and handling practices for flammable gases like acetylene.

The AIT can vary slightly depending on environmental conditions such as pressure and the presence of other substances, but 325 degrees Celsius is widely accepted and recognized in safety data sheets and various chemical safety resources. This knowledge is essential for professionals working with acetylene to effectively mitigate fire risks and implement safety measures.
