The propylene oxide is toxic. Liquid propylene oxide can cause burns to the skin and cornea. Its vapor has irritation and mild anesthesia. Prolonged inhalation of propylene oxide vapor can cause nausea, vomiting, headache, dizziness, and diarrhea. Therefore, there should be some precautions when using, storing, and transporting propylene oxide.

Health hazards of propylene oxide
Exposure to high-concentration propylene oxide vapor can cause eye and respiratory tract irritation and central nervous system depression. In severe cases, irritability, multilingualism, delirium, and even coma can be seen. A few have toxic intestinal paralysis, gastrointestinal bleeding, and heart, liver, and kidney damage. Eye and skin contact can cause burns. Propylene oxide should be used carefully.
General requirements for propylene oxide operation
Operators must undergo special training, strictly abide by operating procedures, be proficient in operating skills, possess knowledge of emergency response, and be fully familiar with the principles of propylene oxide. The airtight operation to prevent leakage and full ventilation. The production, use, and storage sites should be equipped with leak detection alarms, and explosion-proof ventilation systems and equipment should be used. Ensure that the propylene oxide vapor concentration is not easy to diffuse when the concentration is too high. Operators should wear self-absorption filter-type gas masks, anti-static overalls, and oil-resistant rubber gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace.
Special requirements for propylene oxide operation
First, when opening the propylene oxide container, make sure that the work area is well ventilated and there is no spark or ignition source; avoid letting the vapor released by the propylene oxide into the air in the work area. The workshop where propylene oxide is produced and stored must have reliable fire and explosion-proof measures. In the event of an item catching fire, use dry powder fire extinguishers, carbon dioxide fire extinguishers, and sand to extinguish the fire.
Second, when the propylene oxide system leaks, stand on the upper air vent and wear a gas mask for the operation. Keep the water pressure and oil pressure of the equipment normal, and the relevant pipelines should be unblocked. Maintain the equipment well, eliminate the phenomenon of propylene oxide running, emitting, dripping, and leaking, and keeping the equipment in good condition. Finally, the cleaning sewage from the production equipment and the flushing water from the internal floor of the production workshop must be collected in the emergency pool and can be discharged only after passing the treatment.
Propylene oxide storage and transportation requirements
First, propylene oxide should be stored in a cool, well-ventilated special warehouse or storage tank, away from fire and heat sources. The temperature of the warehouse should not exceed 29℃ and keep the container tightly closed. In addition, propylene oxide should be stored separately from oxidants, acids, alkali metals, etc., and should not be mixed. Use explosion-proof lighting and ventilation facilities. It is forbidden to use mechanical equipment and tools that easily generate sparks.
The second is that the transport vehicles of propylene oxide should have dangerous goods transport signs and install satellite positioning devices with driving record functions. Without the approval of the public security organs, transport vehicles shall not enter the restricted areas of hazardous chemical transport vehicles. What is important is that propylene oxide is transported in a special tanker (ship), and the tanker (ship) should be cleaned regularly; when transported in other packaging containers, the container must be sealed with a lid. Transport vehicles should meet the fire safety requirements and be equipped with corresponding firefighting equipment. When transport vehicles enter the factory area, electrostatic grounding devices and flame arresters must be installed to maintain a safe speed.
Emergency measures during emergencies
If inhaled: quickly leave the scene to a place with fresh air and keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately and seek medical attention. If swallowed: Rinse mouth with water, drink milk or egg white, and seek medical attention in time. Skin contact: Take off contaminated clothing immediately, rinse with plenty of running water for at least 15 minutes and seek medical attention in time. In case of eye contact, raise the eyelid immediately, rinse thoroughly with plenty of running water or normal saline for at least 15 minutes, and seek medical advice in time.
