China dangerous-goods road transport foundations cheat sheet
China dangerous-goods road transport foundations · Keep the key ideas within reach.
Material identification, physical hazards and compatibility
Verify actual identity and the applicable transport information.
Principal and subsidiary hazards both matter.
Same broad hazard class does not establish compatibility.
Temperature, confinement and wind affect actual vapor behavior.
Hypothetical exercise values are not statutory limits.
Containment, package selection and traceable records
A document does not prove actual package integrity.
Check compatibility of the complete containment and closure system.
Package, vehicle, axle and restraint limits are independent.
Gross mass and net contents are different quantities.
Resolve discrepancies rather than invent or conceal shipment details.
Dangerous-goods duties, loading and dispatch decisions
Separate the actual transport roles and qualifications.
Route and time controls apply to the specific dangerous-goods movement.
Loading requires the proper procedure and oversight.
Tank surge does not prove a universal filling rule.
Resolve and record discrepancies before treating dispatch as ready.
Danger recognition, information and trained response boundaries
Recognition does not authorize untrained close-range intervention.
No universal distance fits every release.
Empty but unclean containment can retain significant hazards.
Give accurate information and state uncertainty to responders.
Environmental exposure and cleanup require their own appropriate assessment.
Heavy-truck geometry, brakes and freight constraints
Shared truck concepts do not grant every vehicle, combination or professional transport entitlement.
High seating does not remove near-cab blind areas.
Off-tracking and tail swing require checks of the complete swept path.
Brake functions and warnings depend on the actual installation.
Vehicle, axle, restraint and route limits remain independent constraints.
Chinese road control, entitlement and regulatory scope
Separate driving entitlement, driver qualification, vehicle permission and operator authorization.
Interpret the actual Chinese control and lane before choosing a movement.
Subject1 and Subject4 are distinct assessments with shared foundations.
National common-subject practice does not supply every local operating rule.
Check current amendments before treating a precise older number as current.
Hazard recognition, vulnerable users and personal readiness
Connect the observed hazard cue with a specific developing risk.
Priority does not justify creating avoidable danger.
Mirrors and cameras require current observation and have limitations.
Heavy vehicles and two-wheelers both have condition-dependent grip limits.
Medicine legality and personal confidence do not establish fitness to drive.
Vehicle condition, restraint and distinct loading limits
Licence entitlement, roadworthiness and loading remain separate checks.
One satisfactory inspection measurement does not cancel a different defect.
Use actual equipment settings rather than generic pressure or slack numbers.
Actual mass and maximum authorized mass are not interchangeable sign meanings.
An acceptable total does not cancel axle, carrier or attachment limits.
