6.STORAGE RECOMMENDATIONS
The blend polyol should be stored in the sealed container to avoid the absorption of water vapor. During the transportation, it should avoid serious shake and strong sunlight. It should be stored in ventilated place, avoiding light, water and fire. Recommended storage temperature is 15~25ºC

7.SAFTY PRECAUTIONS

Skin allergies may result from moderate skin irritation and minor eye irritation caused by direct contact with ZHD-8002WH type mix polyol. Respiratory allergies can be brought on by repeatedly breathing in large concentrations of volatile gas; this needs to be addressed right away. Treatment with anti-inflammatory and anti-allergic medications is recommended. Please use caution during the procedure to avoid skin contact and splashing into the eyes. You should also wear the appropriate safety gear, such as gloves, goggles, and work clothing. After splattering on the skin or an eye, immediately rinse the area with water for a minimum of fifteen minutes, and then wash the skin with soapy water. Please get medical attention as soon as possible after swallowing.
