Final answer:
To find the BLEVE incident evacuation distance, one would consult the ERG based on the chemical, quantity, and incident type; without the ERG, a specific distance cannot be provided.
Step-by-step explanation:
The question at hand relates to a BLEVE (Boiling Liquid Expanding Vapor Explosion) incident involving a tank containing propane. To determine the suggested minimum evacuation distance, one would typically turn to the ERG (Emergency Response Guidebook) which provides guidelines for first responders dealing with hazardous material incidents. Without the ERG, a specific number cannot be provided here. However, the ERG includes tables and guides based on the chemical involved, its quantity, and the nature of the incident (fire, spill, leak, etc.). The tank dimensions or the mass of the propane involved are typically used to look up the appropriate guide number and then determine the initial isolation and protective action distances.
