| Personal precautions, protective equipment and emergency procedures: It is recommended that emergency personnel wear inflatable breathing apparatus, antistatic clothing and rubber and oil resistant gloves. Do not touch or cross spills. All equipment used in the work should be grounded. Cut off the source of the leak as much as possible. Eliminate all ignition sources. The warning zone is delineated according to the influence area of liquid flow, steam or dust diffusion, and the unrelated personnel are evacuated from the crosswind and the upwind to the safe zone. |
| Environmental precautions: Contain spills to avoid environmental pollution. Prevent spills from entering sewers, surface water and groundwater. Methods and materials for cleaning: Small spills: Collect leaking liquid as much as possible in a closable container. Absorb with sand, activated carbon or other inert materials and transfer to a safe place. It is forbidden to rush into the sewer. A large number of leaks: building a dike or digging a pit. Close the drain pipe. Cover with foam to inhibit evaporation. Transfer to a tank truck or special collector with an explosion-proof pump, recycle or transport to a waste disposal site for disposal. |
Seventh, Handling and storage
| Handling Precautions: Operators should be specially trained to strictly follow the operating procedures. Handling should be carried out in a location with local or full ventilation. Avoid eye and skin contact and avoid inhaling steam. See Section 8 for personal protection measures. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. For canning, the flow rate should be controlled and grounded to prevent static buildup. Avoid contact with incompatible materials such as oxidizing agents (see Section 10 for incompatible materials). Lightly load and unload during handling to prevent damage to packaging and containers. Empty containers may be harmful residues. Wash hands after use and prohibit eating in the workplace. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. |
| Storage Precautions: Store in a cool, ventilated warehouse. The temperature should not exceed 37 °C. It should be stored separately from oxidants and food chemicals, and should not be mixed (see Section 10 for incompatible materials). Keep the container sealed. Keep away from fire and heat. Lightning protection equipment must be installed in the warehouse. The exhaust system should be provided with a grounding device that removes static electricity. Explosion-proof lighting and ventilation settings. It is forbidden to use equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials. |
Eighth, contact control / personal protection
| Engineering Control: Workplace recommendations are separate from other work sites. Closed operation to prevent leakage. Increase ventilation.Set up automatic alarms and accident ventilation. Set up emergency evacuation routes and necessary quarantine areas. Set the red area warning line, warning sign and Chinese warning instructions, and set the communication alarm system. Safety showers and eyewash equipment are provided. |
| Respiratory protection: Wear a filter-type gas mask (half mask) when the concentration in the air exceeds the standard. Air-operated respirators should be worn during emergency rescue or evacuation. |
| Eye protection: Wear chemical safety eye protection. |
| Skin and body protection: Wear protective clothing to penetrate the overalls. |
| Hand protection: Wear rubber and oil resistant gloves. |
| Other protection: Smoking, eating and drinking are prohibited at the job site. After work, take a shower. Maintain good hygiene practices. |
