Hazardous Chemical Transportation and Storage Safety Guide: Essential Vehicle Maintenance and Emergency Tips

Hazardous Chemical Transportation and Storage: Essential Safety Guidelines for Transport Vehicles

The road transportation and storage of hazardous chemicals are crucial links in industrial production and people's livelihood security, while also constituting high-risk and strictly regulated operational segments. Any negligence may trigger major and serious accidents such as leakage, fire, explosion and environmental pollution, posing severe threats to lives, property and the ecological environment. Keep this safety guide to solidify safety defenses and safeguard operational safety.

Daily maintenance is extremely critical for hazardous chemical transport vehicles. The period from summer to autumn features high temperatures, heavy transportation workloads, and a high incidence of vehicle faults. Poor or improper maintenance may lead to medium leakage and other serious accidents with severe consequences. The following standardized guidelines specify the proper use and maintenance of hazardous chemical transport vehicles.

1. Strengthen Vehicle Inspection for Early Risk Detection

• Inspect vehicle identification markings, ensuring all reflective markings on the body and rear are intact and the sprayed medium name matches the loaded hazardous chemical.
• Regularly check the operating condition of lights, braking system and tires; faulty vehicles are prohibited from road operation.
• Constantly monitor tank pressure and temperature, and regularly spray soapy water on flange contact surfaces, ball valves and other connecting parts to check for leakage.
• Inspect emergency shut-off devices before departure; only set off after confirming all facilities work normally and all shut-off valves and loading/unloading ball valves are fully closed.

2. Be Familiar with Cargo Properties and Adhere to Dedicated Vehicle Usage

• All on-board staff must thoroughly understand cargo properties such as flash point, toxicity and expansion coefficient. For media with high expansion coefficients, avoid direct sunlight and monitor tank pressure in real time.
• Transport vehicles must be exclusively used for designated cargo types; mixed loading of different chemicals is strictly forbidden to prevent incompatible reactions.

3. Select Appropriate Transportation Time and Routes

• Under high-temperature weather, adopt daytime rest and nighttime driving to avoid medium expansion and excessive tank pressure surge from intense daytime heat.
• Select routes reasonably, avoid unfamiliar or complex roads, and do not arbitrarily change predetermined routes.
• Avoid densely populated areas and traffic peak hours; in emergencies, drive to an open area whenever possible.

4. Abide by Traffic Regulations to Ensure Driving Safety

• Carry all valid certificates, including the vehicle operation permit and hazardous chemical road transportation pass.
• Load chemicals strictly per approved tonnage and specified medium; overloaded transportation is strictly prohibited.
• Arrange rest reasonably to maintain a clear mind and eliminate fatigue driving.
• Maintain safe speed and following distance, and take timely avoidance measures in case of road congestion.

5. Standardize Loading and Unloading Procedures to Ensure Site Safety

• All loading and unloading must be performed by certified professionals; unauthorized personnel are forbidden to enter the operation area.
• The loading site shall not be used as a temporary rest area, and unrelated operations such as vehicle maintenance are prohibited in the zone.
• For operations in thunderstorm weather, ensure lightning protection and moisture-proof measures are fully in place before starting.

6. Strengthen Personnel Training and Improve Emergency Response

• Transportation enterprises shall conduct regular emergency drills and formulate comprehensive rescue plans.
• All on-board staff must be proficient in operating fire extinguishing devices, stay calm in emergencies, and handle incidents per specifications and emergency plans.
• When a faulty vehicle obstructs traffic, turn on hazard warning lights and place warning signs 50 to 100 meters behind the vehicle on ordinary roads, and more than 150 meters on expressways; personnel shall quickly move to the right shoulder or emergency lane and report to police immediately.
• In case of uncontrollable leakage, park in an open area far from crowds and water sources, report the incident and call the police with detailed chemical information, and immediately evacuate surrounding vehicles and personnel; loitering and watching at the scene are strictly prohibited.
