Syllabus - Hazardous Material Management (FT 802(A))

EXPOSURE AND RESPONSE

General Principle of Chemical exposure and toxic response- Chemical exposure and cancer, chemical exposure and hypersensitivity, toxic response of lungs, liver, kidney, skin chemical exposure and health risk assessment.

DISPERSION MODEL

Toxic release and dispersion models-Design basis, Introduction to Source Models, source model, Flashing Liquids, Liquid Pool Evaporation or Boiling, Conservative Analysis, dispersion model, Pasquill- Gifford model, effect of release momentum, Buoyancy, Dense Gas Dispersion, Toxic Effect Criteria, Release Mitigation.

CHEMICAL RISK ANALYSIS

Flammability-vapour pressure, limits of flammability, Flash points, auto-ignition temperature. Stability- Experimental methods of determination, classifications of instability risk, quantative approach. Toxicity- Evaluation parameter, level of toxic risk, problem posed by determination of toxicity risk level, Quantative estimation method.

EXPLOSION HAZARDS

Gas and vapor cloud explosion & means of preventing and mitigating in the process industry, Explosion in clouds of liquid droplets in air (spray/mist explosions), Dust Explosion. Stability and sensitivity tests, Classification of materials with explosive potential, Hazard prediction by thermodynamic calculations, Prevention and control of explosions and detonations- diluting a release, purging and inerting, venting, explosion relief, flame arrestors, explosion suppression.

STOREAGE AND HANDLING

Types of storage-general considerations for storage layouts- atmospheric venting, pressure and temperature relief- relief valve sizing calculations- storage and handling of hazardous chemicals and industrial gases, safe disposal methods, reaction with other chemicals, hazards during transportation- pipe line transport- safety in chemical laboratories. Safety provisions like level and flow indicators- alarms, colour coding for pipe lines and cylinders.
