Cheat Sheet

  1. Goods Classification -

    Review the nine UN classes of dangerous goods - from explosives to miscellaneous hazards - using a mnemonic like "Every Good Firefighter Again Thwarts Radioactive Corrosive Mischief." Mastering classification is fundamental for accurate dangerous goods handling and awareness answers. Refer to UN Model Regulations or Transport Canada's TDG guide for official definitions.

  2. Packaging Groups -

    Understand Packaging Groups I, II, and III, which rank goods by hazard severity (I=high, III=low); for example, sulfuric acid (PG II) poses a moderate hazard requiring UN-approved drums. Knowing packaging requirements ensures compliance and prevents leaks or reactions in transit. Consult ICAO TI or IATA DGR references to match materials with proper PG ratings.

  3. Labeling & Marking -

    Learn the difference between labels (100 mm squares) and placards (250 mm or larger) and use the correct hazard diamond for each UN class. Applying the right label not only meets regulations but also aids first responders - crucial for fedex dg test answers. Check FedEx's Dangerous Goods Regulations for size and placement standards.

  4. Shipping Documentation & UN Numbers -

    Memorize the format "UNXXXX Proper Shipping Name, PG#" (e.g., UN1203 Flammable Liquid, PG II) to ace any dangerous goods test. Accurate entries on shipper's declarations and SDS references prevent delays and fines. Use the Emergency Response Guidebook (ERG) to match UN numbers with response protocols.

  5. Training & Refresher Requirements -

    Keep your TG training current with mandatory refresher intervals (typically every 24 months) and review fedex dg training answers for carrier-specific nuances. Hands-on scenario drills build confidence in package inspections, labeling, and documentation. Rely on IATA, ICAO, and FedEx DG training materials for the most up-to-date course content.
