Hazard 1: Asphalt Poisoning
Asphalt storage tanks contain large quantities of asphalt, which produces harmful gases during heating. Workers exposed to hot asphalt for extended periods may experience asphalt poisoning through skin and respiratory exposure to these harmful gases and dust. Preventive Measures: Gas masks are generally used for protection. Workers must wear gas masks to prevent inhalation of asphalt fumes. Full-body protection is also essential; work clothes should prevent contact with liquid droplets and dust.
Hazard 2: Burns
Asphalt tanks are heated by heat transfer oil. While the oil pipes are insulated, exposed points such as valves can lead to burns due to corrosion if not properly maintained. Accidental contact during operation could result in burns.
Preventive Measures: Workers should stand in a safe position on the operating table to prevent burns. Workers should wear protective glasses and avoid using heat-sensitive chemical glass lenses. To prevent damage to thick glass surfaces from hot asphalt droplets that could impair vision, a thin layer of glass should be embedded in front of the lens. Workers should wear protective clothing to prevent burns from liquid droplets and, ideally, wooden-soled boots to protect the soles of the feet from hot asphalt. Heating pipes should be regularly maintained, inspected, and repaired to prevent direct contact and burns.

Hazard 3: Fire Asphalt is flammable. Large quantities of asphalt stored in asphalt tanks are difficult to extinguish once ignited by an open flame, easily causing a large-scale fire.
Preventive Measures:
1. Smoking and open flames are strictly prohibited inside the asphalt storage station. Personnel entering the station must not carry flammable or explosive materials. Safety measures must be in place when using open flames.
2. The asphalt storage station must be equipped with fire-fighting equipment and materials. All fire-fighting equipment must not be moved or misused and must be inspected regularly.
3. Dedicated personnel should be assigned to be responsible for safety and fire prevention. Management personnel must learn and understand the performance of fire-fighting equipment and master fire prevention knowledge.
4. Before operation, all equipment, facilities, and the environment must be checked and confirmed to be in a safe working condition. During operation, relevant personnel should carefully patrol and inspect to prevent leaks, spills, drips, and condensation.
Hazard Four: Lightning Strike
Asphalt tanks are approximately 12 meters high, making them susceptible to lightning strikes in areas with frequent thunderstorms, potentially leading to accidents. Prevention Measures: Lightning protection devices utilize a protruding position above the protected object to attract lightning, which is then discharged into the ground through down conductors and grounding devices, protecting the asphalt tank from lightning strikes. Common lightning protection devices include lightning rods, lightning wires, and lightning protection networks.
