What Is a Body Tissue Irritant?
Many chemical substances are classified as body tissue irritants. This is a very broad and general statement that means you should avoid getting this material in your eyes or on your skin— it may cause itching, irritation or a rash. The symptoms depend on the part of the body exposed, the duration of contact and your body’s reaction to the chemical. Different people react differ- ently to specific chemicals. Bottom line, always wear gloves, goggles and aprons when handling these materials.
