Prevention: Obtain specific instructions before use. Do not handle until all safety
precautions have been read and understood. Use only outdoors or in a well-ventilated
area. Do not eat 、drink or smoke when using this product. Avoiding breathing
dust/fume/gas/mist/vapors/spray. Wear protective gloves/protective clothing/eye
protection/face protection. Such as inadequate ventilation, wear respiratory protection.
Wash thoroughly after handling. The contaminated work clothes may not be brought out,
avoid release to the environment.
Emergency: Such as skin contamination: wash with plenty of soap and water. In case of
skin irritation or rash: call a poison/doctor. Remove contaminated clothing, clean the rear
can be re used. If inhaled: the victim will be transferred to the fresh air, to maintain a
comfortable position in the breath. If there is a respiratory disease, call the interpretation
center or doctor. Such as into the eyes: rinse with water carefully for a few minutes. If
wearing contact lenses and can be easily removed, remove contact lenses. Continue
washing. If still feel eye irritation: call a poison/doctor. Such as exposure to or have
doubts: call a poison/doctor. Collection overflow.

6. Accidental Release Measures
Rapid evacuation from air leaks to safety areas, isolation and tight access to staff
cleanliness, personnel restrictions should wear protective clothing, gloves, boots and
respirator isolation. If possible, cut off leakage sources to minimize exposure. Eliminate
regional air leakage from all fire sources and leakage areas, do not contact leaks to
diffuse or leak into drains. Spray foam having a protein surface to reduce vapor
concentration in the presence of a large-area leak, covered with sand or commercially
non reactive material.
