First Aid Measures
Emergency procedures for chemical exposure incidents
If breathed in, move person into fresh air. If not breathing, give artificial respiration. Consult a physician.
Wash off with soap and plenty of water. Take victim immediately to hospital. Consult a physician.
Flush eyes with water as a precaution.
Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.
Immediate Medical Attention
Consult a physician.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Carbon oxides, nitrogen oxides (NOx)
Firefighter Protection
Wear self contained breathing apparatus for fire fighting if necessary.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection

Exposure Controls / PPE
Occupational exposure limits, engineering controls, and protective equipment
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique (without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it. Full contact Material: Nitrile rubber Minimum layer thickness: 0,11 mm Break through time: 480 min Material tested:Dermatril® (KCL 740 / Aldrich Z677272, Size M) Splash contact Material: Nitrile rubber Minimum layer thickness: 0,11 mm Break through time: 480 min Material tested:Dermatril® (KCL 740 / Aldrich Z677272, Size M) data source: KCL GmbH, D-36124 Eichenzell, phone +49 (0)6659 87300, e-mail sales@kcl.de, test method: EN374 If used in solution, or mixed with other substances, and under conditions which differ from EN 374, contact the supplier of the CE approved gloves. This recommendation is advisory only and must be evaluated by an industrial hygienist and safety officer familiar with the specific situation of anticipated use by our customers. It should not be construed as offering an approval for any specific use scenario.
Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle respirator type N99 (US) or type P2 (EN 143) respirator cartridges as a backup to engineering controls. If the respirator is the sole means of protection, use a full-face supplied air respirator. Use respirators and components tested and approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Complete suit protecting against chemicals, The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace.
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.
