SUMMARIZED COMPRESSED POINT FORM CONTENT AREAS COVERED
IATA DGR General Philosophy & Applicability: Primary purpose (safe air
transport of dangerous goods), ICAO Technical Instructions relationship (IATA DGR
more restrictive), annual updates (effective January 1 each year), shipper
responsibilities for proper classification/packaging/labeling/documentation, operator
(airline) acceptance responsibilities, state of origin vs. state of destination
requirements, Shipper's Declaration (DGD) completion requirements, training
requirements (initial + recurrent every 24 months), 6 training categories (shippers,
packers, forwarders, airlines, ground handling, security), operator variations (airline-
specific rules), state variations (country-specific rules), hidden dangerous goods
concept, pilot-in-command authority for accepting/rejecting shipments.
Classification of Dangerous Goods: 9 hazard classes in order (Explosives, Gases,
Flammable Liquids, Flammable Solids, Oxidizers, Poisons, Radioactive, Corrosives,
Miscellaneous), divisions within each class (Class 1: 1.1-1.6; Class 2: 2.1, 2.2, 2.3;
Class 4: 4.1, 4.2, 4.3; Class 5: 5.1, 5.2; Class 6: 6.1, 6.2), flash point thresholds
(flammable ≤60°C, combustible 60-93°C), UN numbers (4-digit identification), proper
shipping names from Dangerous Goods List, packing groups (PG I highest hazard,
PG II intermediate, PG III lowest hazard), subsidiary hazards (additional hazards
beyond primary), marine pollutants, forbidden materials, dangerous when wet
materials, auto-ignition temperature concepts.
Packaging Requirements: Purpose of packaging (protect goods/prevent leaks), UN
specification packaging (performance standards: drop test, leak test, hydrostatic
, test), UN packaging codes (e.g., 4G = fiberboard box, 1A1 = steel drum), packing
instructions (PI numbers for specific materials), limited quantity exceptions (small
quantities with reduced requirements), excepted quantity exceptions (very small
quantities with minimal requirements), combination packaging (inner + outer
packaging), absorbent material requirements for liquids, cushioning material
requirements, closure requirements, ventilation requirements for certain materials,
overpack concept (outer packaging containing multiple packages), overpack marking
requirements.
Marking & Labeling: Markings (text-based information: proper shipping name,
UN/NA number, limited quantity mark, excepted quantity mark, handling marks like
"This Side Up", "Fragile", "Keep Away From Heat"), labels (graphic symbols: primary
label for primary hazard class, subsidiary label for additional hazards), label size (4
inches/100 mm on each side), specific labels for each hazard class (Flammable
Liquid: red label; Flammable Gas: red label; Non-Flammable Gas: green label;
Poison: skull and crossbones; Corrosive: test tube on metal; Radioactive: trefoil
symbol; Explosive: orange background; Oxidizer: yellow with flame; Organic
Peroxide: yellow; Dangerous When Wet: blue; Spontaneously Combustible:
white/red; Flammable Solid: white/red stripes; Miscellaneous: white with black
stripes; Infectious Substance: biohazard symbol).
Documentation & Shipper's Declaration: Shipper's Declaration for Dangerous
Goods (DGD) as primary document, required contents (UN number, proper shipping
name, hazard class, packing group, total quantity), correct order (UN # → Proper
Shipping Name → Hazard Class → Packing Group), shipper's certification
signature, emergency response telephone number (24-hour), handling information
(temperature/ventilation requirements), retention period (at least 12 months), Air
Waybill (AWB) relationship, Notice to Captain (NOTOC) listing all dangerous goods
, on board, Dangerous Goods Manifest summary, training record retention (at least 24
months), training frequency (every 24 months), new personnel training requirement
(before performing duties).
Radioactive Materials (Class 7): Transport index (TI) for radiation level, three
categories (I: TI=0, II: TI up to 1, III: TI > 1), labels (White-I, Yellow-II, Yellow-III),
Type A packaging (normal transport conditions only), Type B packaging (accident
conditions), Type C packaging (air transport), exempt packages (low activity),
criticality safety index (CSI) for fissile materials, fissile classification, special form
classification (non-dispersible), low specific activity (LSA), surface contamination
limits, radiation level measurements, maximum TI per package (10).
Special Provisions & Exceptions: CAO (Cargo Aircraft Only) vs. PAX (Passenger
Aircraft), Limited Quantity exception (small quantities with reduced requirements),
Excepted Quantity exception (very small quantities with minimal requirements),
Special Provision A88 (lithium batteries), Special Provision A48 (dry ice), Special
Provision A99 (magnetized materials), Special Provision A123 (infectious
substances), Special Provision A154 (organic peroxides), Special Provision A180
(explosives), Special Provision A190 (gases), Special Provision A200 (radioactive
materials), Special Provision A210 (corrosives), Special Provision A220 (flammable
liquids), Special Provision A230 (oxidizers), Special Provision A240 (flammable
solids), Special Provision A250-A310 (additional packaging requirements for various
classes).
Emergency Response & Incident Reporting: First response actions (call 911),
Emergency Response Guidebook (ERG) usage, guide pages for hazard
identification, protective action distances, evacuation distances, shelter-in-place
procedures, isolation distances, National Response Center (NRC) reporting,
Dangerous Goods Incident Report submission to applicable authority, incident report
, retention (at least 3 years), Emergency Response Plan development by employer,
security plan for high-risk shipments, pilot-in-command responsibilities, in-flight
release procedures, decontamination procedures, Incident Command System (ICS)
for multi-agency response.
Training & Security: Training requirements (initial + recurrent every 24 months), 6
training categories (shippers, packers, forwarders, airlines, ground handling agents,
security personnel), training record retention (at least 24 months), new personnel
must train before duties, security threat assessment for certain personnel, security
plan requirements for high-risk shipments, TWIC card for port access, security
awareness training for threat identification/reporting.
Operational Requirements: CAO vs. PAX designations for aircraft types, packaging
compatibility requirements, segregation and separation of incompatible dangerous
goods, quantity limitations per package, handling requirements (temperature,
ventilation, orientation), stowage and loading requirements on aircraft, dangerous
goods location on aircraft (NOTOC), pilot notification and responsibilities, ground
handling procedures.
Regulatory Framework & Compliance: IATA DGR relationship to ICAO Technical
Instructions (IATA more restrictive), annual updates effective January 1, state
variations (country-specific additional requirements), operator variations (airline-
specific additional requirements), enforcement agencies (PHMSA, FAA, IATA),
penalties for violations (up to $75,000), shipper responsibilities vs. carrier
responsibilities, forbidden materials (prohibited from air transport), hidden dangerous
goods concept, declaration of dangerous goods.
