Causes resness and pain. The substance irritates the eyes. Skin
Causes redness. Inhaled
Causes cough, headache, shortness of breath, sore throat, wheezing, fatigue and cramps. The substance irritates the respiratory tract. Inhalation of dust may cause asthmatic reactions. The substance can be absorbed into the body by inhalation of its aerosol. Evaporation at 20 deg C is negligible. A harmful concentration of airborne particles can, however, be reached quickly. 2.2 Health Effects - Chronic
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. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance. Repeated or prolonged contact with skin may cause dermatitis.
