HazoraRead applicability before choosing a column
The ERG 2024 user instructions explain when Table 1 applies and direct the reader to confirm the material's exact entry. They distinguish spill categories and day from night. Table 2 concerns water-reactive materials, while Table 3 addresses specified large-spill cases for six common toxic inhalation hazard gases.
| Recorded input | Why it belongs in a training note |
|---|---|
| Exact entry | Similar names or shared IDs need careful matching |
| Applicable table | The three tables serve different cases |
| Selected conditions | A value belongs to a particular row and column |
Distinguish the two kinds of distance
Initial isolation distance and downwind protective action distance describe different reference concepts. Do not copy one into a field intended for the other. Consult the official diagrams and instructions when learning how the zones are represented, including the wind information required by the book.
Hazora keeps the ERG tables and guide content available offline. Its native map feature is separate from this educational page. A map rendering does not remove the need to verify the underlying material, conditions and official procedure. For incident decisions, trained responders must use the complete current guidance and site information.
