Emergency Procedures and Crisis Management in the Transport of Dangerous Goods
What are emergency procedures and crisis management in the transport of dangerous goods?
Emergency procedures and crisis management in the transport of dangerous goods form a complex system of preventive, preparatory, response, and recovery measures designed to minimize risks and effectively manage extraordinary events that may arise during the transport of dangerous goods (English: dangerous goods, DG) and hazardous materials (hazardous materials, HazMat). This system connects legislative requirements, technical standards, operational plans, human resources, and specialized equipment into a functional framework aimed at protecting life, health, property, and the environment from the destructive consequences of accidents, fires, leaks, or explosions.
Why is this system necessary?
- Risks associated with transport are extreme: a range of chemicals, gases, explosives, corrosives, toxic and radioactive materials are routinely transported by road, rail, water, and air.
- Accidents can occur as a result of technical failure, human error, unexpected events (e.g., extreme weather), or improper handling.
- Consequences can be catastrophic: leaks of toxic substances, fires, explosions, water contamination, soil contamination, threats to public health, and long-term environmental damage.
- The goal is not only reactive intervention in case of an accident, but primarily proactive planning, prevention, and preparedness.
Core of the issue: Cyclical model of crisis management
Crisis management in the field of transport of hazardous materials is built on four fundamental pillars that create a continuous cycle of safety:
Overview of crisis management pillars
| Pillar | Main objectives and tools | Responsible entities |
|---|---|---|
| Prevention | Risk identification, proper packing, marking, training, maintenance | Shipper, carrier, safety advisor |
| Preparedness | Emergency plans, emergency equipment, exercises, information availability | Carrier, emergency services, airport authorities |
| Response | Rapid identification, intervention, evacuation, crisis communication | Driver/pilot, emergency services, Police |
| Recovery | Decontamination, reporting, analysis, procedure review | Carrier, remediation companies, state authorities |
Prevention: How to prevent accidents and minimize risks
Prevention is the cornerstone of safe transport of dangerous goods. The latest findings and requirements of ADR and IMDG Code emphasize:
Key preventive steps
- Risk assessment: Detailed analysis of the physical and chemical properties of the substance, hazards during transport, and possible accident scenarios.
- Proper classification: Each substance is classified according to ADR or IMDG Code into a class and hazard group; for example, gasoline (UN 1203) into class 3 (flammable liquids).
- Packing and packaging: Only certified packaging approved for the specific substance and method of transport (drums, IBC containers, tanks, transport containers) are used. ADR distinguishes three packaging groups (I – high risk, II – medium, III – low).
- Marking and labeling: Mandatory safety marks (diamond-shaped labels), UN numbers, inscriptions, and in some cases directional arrows (according to ADR 5.2.1.10). Marking must be visible even when multiple substances are packed together.
- Documentation: Each shipment must be accompanied by a transport document with precise information (UN number, name, packaging group, quantity, tunnel restrictions, etc.).
- Personnel training: Drivers must complete ADR training (for specific classes and types of transport), be equipped with personal protective equipment (reflective vest, gloves, glasses, flashlight), and have experience with the transport of dangerous goods.
- Vehicle and equipment maintenance: Transport vehicles must meet ADR requirements – for example, tank construction, electrical equipment, brakes, fire protection, speed limits.
- Safety advisor (DGSA): Mandatory for companies handling dangerous goods; responsible for compliance with regulations, training, and reporting.
Preparedness: Planning and emergency equipment
If prevention proves insufficient, preparedness for extraordinary events is key.
Main elements of preparedness
- Emergency plans: Internal procedures and scenarios, who does what in case of an accident, including contacts for emergency services, emergency services, and experts (CHEMTREC, TIS).
- Emergency equipment in the transport vehicle: Fire extinguishers (minimum number and volume according to the type and quantity of goods), absorbents, collection trays, sealing agents, personal protective equipment for the crew.
- Written ADR instructions: Mandatory document in the driver’s cab (instructions for individual hazard classes, first aid principles, leak procedures).
- Simulations and exercises: Regular drills of intervention according to emergency scenarios – including cooperation with fire brigades, police, rescue services, and local authorities.
- Ensuring information resources: Access to current versions of ADR, ERG (Emergency Response Guidebook), databases, and safety data sheets (SDS).
Response: Procedure in case of an extraordinary event
In case of an accident, the most important thing is a rapid, coordinated, and properly targeted response. Key steps include:
Practical intervention step by step
- Immediate reaction of driver/pilot:
- Stop the engine, activate warning lights, secure the vehicle against movement.
- Equip with personal protective equipment, secure documents and written instructions.
- Quick assessment of the situation (type of leak, smell, color, weather conditions).
- Call emergency line 112/150 – report the accident with precise information (UN number, location, nature of substance, quantity, threat to surroundings).
- Initial measures at the scene:
- Warning to surroundings, prohibition of smoking and use of open flame.
- Attempt to limit the leak by safe means (use of absorbent, sealing of crack, deployment of collection tray), only if safe.
- Intervention by emergency services:
- Site survey, reading of UN number and safety marks, use of ERG or safety data sheet to determine the exact procedure.
- Deployment of protective equipment (breathing apparatus, chemical suits), fire protection measures, establishment of isolation and evacuation zones.
- Measures to prevent the spread of substance into sewage, water bodies, soil (dikes, absorbents).
- Crisis communication: information to media, authorities, public.
- Support and management of intervention:
- Airport authorities, safety advisor, specialized remediation companies.
- Coordination between state bodies and private entities.
Recovery: Return to normal and prevention of recurrence
After managing the acute phase, recovery begins:
- Decontamination: Professional removal of leaked substance, cleaning of roads, removal of contaminated soil, ecological disposal of waste.
- Remediation work: Suction of remaining goods, removal of damaged vehicles, inspection and revision of equipment.
- Reporting and investigation: Obligation to report the accident to the relevant authorities (according to ADR), investigation of the cause and circumstances of the accident.
- Analysis and plan updates: Evaluation of the intervention, revision and improvement of emergency procedures, employee training based on new findings.
Legislative and regulatory framework
The safety of transport of dangerous goods is not left to chance. It is firmly anchored in a system of international conventions and national legislation:
International conventions and their significance
- ADR (Accord Dangereux Routier): Basic standard for road transport of dangerous goods in Europe and many other countries. It establishes rules for packing, marking, documentation, training, and technical requirements for vehicles and equipment.
- RID: Rules for rail transport.
- ADN: Inland water transport.
- IMDG Code: Maritime transport (containers, ships).
- ICAO/IATA DGR: Air transport – with emphasis on emergency procedures on board, information availability to the pilot, special crew training.
National legislation of the Czech Republic
- Act No. 111/1994 Coll., on road transport: Implements ADR into Czech law.
- Act No. 239/2000 Coll., on the Integrated Rescue System: Defines the roles and procedures of emergency services.
- Act No. 240/2000 Coll., Crisis Act: Establishes the framework for state crisis management.
- Decrees and implementing regulations: Specify detailed obligations for transport, packing, marking, record keeping, training, and emergency planning.
