Give artificial respiration only if breathing hasstopped. If breathing is difficult, give oxygen. Seek immediate Contact / contaminated clothing. Wash affected area with soap andwater. Seek medical attention if irritation occurs or immediately with water for at least 20 minutes. Forcibly holdeyelids apart to ensure complete irrigation of eye tissue. Seek immediatemedical not induce vomiting. If vomiting occurs, lean victim forward to preventbreathing in vomitus.

4 Give large amounts of water. Do not give anything by mouth to an unconscious or convulsing person. Seek immediate medical internal toxicity is low, irritant effects of high concentrations mayproduce corneal opacities, and vesicular skin reactions in humans withabraded skin only.
