In the event of chemical contact on skin, rinse the affected area with water for at least 15 minutes, removing clothing while rinsing, if necessary. Seek medical attention if symptoms persist. Chemical contact with eyes can be particularly dangerous, resulting in painful injury or blindness. Wearing safety goggles or a face shield can reduce the risk of eye contact. Eyes which have been in contact with chemicals should be rinsed immediately with water continuously for at least 15 minutes.
Medical attention is necessary if symptoms persist.
The lungs are the most common route of entry for gases, vapors and particles. Such materials may be transported into the lungs and harm the tissue or go enter the bloodstream. Most chemicals have an odor which is perceptible at a certain concentration, referred to as the odor threshold. Olfactory fatigue may occur when exposed to high concentrations or after prolonged exposure to some substances. This may cause the odor to seem to diminish or disappear, while the danger of over-exposure may remain.
