| Maps and diagrams (dis-adv) | May not be up to date and may be inaccurate |
| Monitoring equipment (adv) | critical info on hazards present at hazmat incident site |
| Monitoring equipment (dis-adv) | do not rely on only one piece of equipment |
| Reference manuals (adv) | many ref manuals available from various ind. , corps, and fed agencies |
| Reference manuals (dis-adv) | contain slightly different viewpoints and depths |
| Technical information centers | CHEMTREC, CANUTEC SETIQ and NRC |
| Technical information centers (adv) | Readily available, can activate emergency response mutual aid network |
| Technical information centers (dis-adv) | may provide conflicting info |
| Technical information specialists (adv) | experiance and edu |
| Technical information specialists (dis-adv) | difficult to contact, no ind knows all answers |
| Cryogenic Liquid Spills | Expansion ration (560- 1,445)gals to 1 gal, expands rapidly at room temp |
| Hepatoxins | liver damage, Signs and symptoms: jaundice and liver enlargement; chemicals- carbon tetracholoride and nitrosamines |

| Determining Pressure in bulk packing or facility containers | Pressure gauges, Temperature on contents |
| Determining Lading (liquid) remaining in damaged bulk packing | Shipping papers, Container specification marking, Gauging devices, Frost line |
| Cracks | a narrow split or break in the container’s metal that can penetrate through the metal of the container and may also be caused by fatigue (Catastrophic failure) (breach) |
| Gouges | Reduction in container thickness made by a sharp, chisel-like object (breach) |
| Scores | Reduction in container shell thickness made by a relatively blunt object (only catastrophic failure if found on welding’s) |
| Dents | A deformation of the container metal made from the impact of a relatively blunt object |

| Handbook of Reactive Chemical Hazards | (Bretherick) over 5000 chemicals- Chemicals that are reactive hazards |
| Hazardous chemicals Desk Reference | (Lewis) appr 5000 chemicals- Safety profiles, synonyms, physical properties,standards, and recommendations of government agencies for important and potentially hazardous chemicals |
| Fire protection systems | allows application of fire extinguishing agents quicker and to manage an incident in the early stages |
| Monitoring and detection systems | allows for the initiation of control actions while incident is small, early notification [limits threats to other containers] |
