Other Information

Do NOT take working clothes home.Rinse contaminated clothing with plenty of water because of fire hazard.Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.Depending on the degree of exposure, periodic medical examination is suggested.
