What the table fields mean
- Hazard identification number (Kemler)
- The first digit is the main hazard (2 gas, 3 flammable liquid, 4 flammable solid, 5 oxidising, 6 toxic, 8 corrosive, 9 miscellaneous), the next digits are additional hazards, a repeated digit (e.g. 33) means an intensified hazard, an X before the number means a dangerous reaction with water.
- Transport category
- The transport category (0 to 4) sets the multiplier: according to ADR Check, category 1: multiplier 50, category 2: multiplier 3, category 3: multiplier 1, category 4: multiplier 0 (no limit), and category 0 means the exemption does not apply. Points are the net quantity (kg or L) times the multiplier.
- Multiplier for the 1000-point limit
- Points are the net quantity (kg or L) times the multiplier; a load total not exceeding 1000 points falls within the ADR 1.1.3.6 exemption.
