ALOHA

This course provides training on ALOHA, a modeling program designed for emergency responders and planners to estimate chemical release scenarios. Participants will learn to predict toxic cloud dispersion, fire, and explosion hazards, and calculate release rates to enhance emergency response planning and decision-making.

• Understand the purpose and capabilities of ALOHA in modeling chemical releases
• Learn how ALOHA integrates with emergency response and planning efforts
• Estimate toxic cloud dispersion and predict hazard zones (toxicity, flammability, thermal radiation, overpressure)
• Calculate chemical release rates from tanks, puddles (land and water), and gas pipelines
• Model release rate changes over time for various scenarios
• Simulate toxic gas clouds, BLEVEs (Boiling Liquid Expanding Vapor Explosions), jet fires, vapor cloud explosions, and pool fires
• Evaluate hazards specific to each release scenario
• Use ALOHA to create threat zones and assess Level of Concern (LOC) thresholds
• Apply ALOHA outputs to real-world emergency response planning and decision-making
