Emergency treatment of propylene leakage
      Quickly evacuate the contaminated area to the upper wind, and isolation, strictly restrict access. Turn off the fire. Wear self-contained positive pressure breathing apparatus and antistatic work clothes. Try to cut off the source of leakage. Use industrial mulching or adsorption/absorbent to stop gas from entering in areas such as drains near the leak point. Proper ventilation to promote diffusion. Spray water to dilute and dissolve. Large quantities of waste water from the construction of embankments or pits. If possible, use an exhaust fan to send the leaking gas to an open area or install a suitable nozzle to burn it off. Leaking containers should be properly disposed of, repaired, and inspected after use.
