🎯 Module 1 Learning Goals
✓ Classify any substance across the 9 UN Hazard Classes and apply the Precedence of Hazards table (ICAO TI 2;0.3) when a material has multiple hazards.
✓ Read all columns of the ICAO TI Table 3-1 / IATA DGR 4.2 Dangerous Goods List, including Special Provisions (A-codes), EQ/LQ columns, and Passenger vs. Cargo Aircraft Packing Instructions.
✓ Calculate the Mixed-Packing Q-Value formula (ICAO TI 4;1.1.9) and round UP to the first decimal place so incompatible or over-limit multi-item boxes are never tendered.

LESSON SECTION 1 OF 3
ICAO TI Part 3;2 · UN Model Regs Vol. I Ch. 3.2
1. Reading the Dangerous Goods List (ICAO Table 3-1 / IATA 4.2)
1.
Every regulated article is assigned a 4-digit UN or ID number, an exact Proper Shipping Name (PSN), a primary Class/Division, any Subsidiary Hazard(s), and—where applicable—a Packing Group (I = high danger, II = medium danger, III = low danger).
2.
Entries carrying UN Special Provision 274 (or ICAO/IATA star symbol ★) require the recognized chemical or biological technical name in parentheses immediately after the N.O.S. Proper Shipping Name (e.g., Flammable liquid, n.o.s. (isopropanol, xylene)).
3.
Articles of Classes 1, 2, 7, Divisions 5.2 and 6.2, and self-reactive substances of Division 4.1 do not take a Packing Group; assigning PG II to Compressed gas, flammable, n.o.s. (UN 1954) or Lithium ion batteries (UN 3480) is a mandatory document rejection.

📋 Quick Dock Checklist Summary (Module 1)
☑ Verify UN Number & Proper Shipping Name match Table 3-1 exact spelling (singular/plural).
☑ If Special Provision A274 / UN SP 274 applies, verify the chemical technical name is in parentheses.
☑ Compare Net Quantity per package against Column 11 (PAX) or Column 13 (CAO).
☑ If multiple DG share one outer package, compute Q = n1/M1 + n2/M2 (must be <= 1.0 rounded UP).
