Correct answer

Handle packages carefully to avoid damage, follow proper procedures, keep sources of ignition away from flammables, and never accept leaking packages

  1. A Handle packages carefully to avoid damage, follow proper procedures, keep sources of ignition away from flammables, and never accept leaking packages
  2. B Smoke while loading
  3. C Work as fast as possible ignoring safety
  4. D Throw packages to save time

Why this is the answer

When loading/unloading hazmat, the driver should: HANDLE packages CAREFULLY to avoid damage (don't drop, throw, or roll); follow proper loading procedures and securement; keep IGNITION SOURCES (cigarettes, flames, sparks) away from flammable materials (NO SMOKING near flammables/explosives); never load LEAKING or damaged packages (refuse them); ensure compatible materials (some hazmat can't be loaded together — segregation rules); turn off the engine when fueling/loading certain materials; chock wheels. CDL hazmat. Careful handling prevents spills, fires, and reactions. Knowing safe hazmat loading precautions (careful handling, no ignition sources, refuse leaks, segregation) is commonly tested.
