China dangerous-goods road transport foundations flashcards

30 cards. Read the term and the definition here. The deck at the top of this page is optional.

Subsidiary hazard

An additional relevant hazard accompanying the principal transport hazard, which must not be ignored merely because another class appears first.

Material identity

The verified substance or article information used to establish the actual applicable transport description rather than a guessed commercial-name association.

Compatibility

Suitability of materials or containment components together under actual conditions, not established solely by shared broad hazard class or mechanical fit.

Oxygen displacement

Reduction of breathable oxygen by another gas, creating an asphyxiation hazard independently of whether the released gas is flammable.

Vapor accumulation

Collection of released vapor under actual density, temperature, wind and confinement conditions, which cannot be ruled out by odor absence.

Closure integrity

The actual condition and suitability of the complete containment closure, not restored merely by a readable label or complete document.

Package tare

The stated mass of empty packaging, distinguished from its contents when applying the explicit definitions in a shipment calculation.

Gross package mass

The combined contents and packaging mass under the relevant stated model, distinguished from net contents or package count alone.

Approval scope

The conditions and uses covered by the actual package approval, rather than permission for every material, filling amount or substituted component.

Shipment discrepancy

A mismatch between actual cargo and relevant records that requires proper verification and resolution rather than arbitrary relabeling or concealment.

Carrier permission

The actual authorization applying to the transport undertaking and shipment, distinguished from an individual driver's motor-vehicle licence or qualification.

Controlled loading

Material transfer conducted under the applicable procedure, suitable equipment and responsible oversight rather than an improvised sequence from another product.

Tank surge

Movement of liquid within containment that can affect vehicle dynamics, without itself establishing one universal permitted filling percentage.

Route restriction

An applicable control over the actual dangerous-goods movement, which is not cancelled by a navigation application or an empty road.

Dispatch discrepancy

An unresolved condition such as mismatched quantity, missing authorization or equipment fault that prevents a record from demonstrating readiness.

Accurate uncertainty

A candid description of information not yet verified, supplied alongside useful known facts instead of an invented material identity or diagnosis.

Secondary casualty

An additional injured person created by exposure during an unsafe approach or unprotected rescue rather than the original incident alone.

Exposure pathway

A route through which a material can reach people or the environment, including drainage and vapor movement beyond the immediate package.

Response handover

Transfer of legitimate records and actual observations to the authorized responders, clearly distinguishing confirmed facts from unresolved assumptions.

Residue assessment

Appropriate evaluation of contaminated material for subsequent handling and classification rather than universal ordinary-rubbish disposal or invented blanket categorization.

Driving entitlement

The authorization attached to the actual motor-vehicle licence and vehicle classes, distinguished from every possible professional transport qualification or operating permission.

Professional driver qualification

The applicable occupational authorization for the actual transport activity, which is not automatically supplied by possessing a motor-vehicle driving licence.

Operator authorization

The permission and duties applying to the transport business, distinguished from the individual driver and the particular vehicle's documentation.

National and regional scope

The distinction between shared national subject requirements and the actual local rules for a city or operating area, avoiding a false claim of complete local coverage.

Toter Winkel

A blind area not adequately visible through the available direct or assisted view, requiring appropriate current checks rather than an assumption that it is empty.

Target fixation

Attention locked onto a hazard or object that reduces awareness of the wider traffic situation and can interfere with choosing the intended path.

Conspicuity

How readily a road user can be noticed in the actual environment, improved by suitable equipment but never guaranteeing that another person has seen them.

Driving fitness

The actual ability to drive safely given fatigue, illness, substances and other factors, not established solely by possessing a licence or feeling confident.

Available grip

The traction available under the actual tire, surface, load and motion conditions, shared among braking and steering demands rather than guaranteed by ABS.

Permitted maximum mass

A specified authorized vehicle value, distinguished from actual current mass and applied according to the exact rule or sign definition.
