SECTION 4: FIRST-AID MEASURES
4.1 Description of Necessary First-Aid Measures:
Inhalation: Remove to fresh air. If person is not breathing give artificial respiration. If breathing becomes difficult give oxygen. Seek medical attention if necessary.
Skin: Wash with copious amounts of soap and water for at least fifteen minutes; removing contaminated clothing and shoes. Seek medical attention if necessary.
Eye: Flush with copious amounts of water for at least fifteen minutes. Remove contact lens after five minutes of washing, and then continue to irrigate the eyes. Ensure adequate flushing by separating the eyelids with protected fingers. Seek medical attention if necessary.
Ingestion: Rinse mouth with water. Do not induce vomiting unless told to do so by a medical professional. Contact the Poison Control Center or seek medical attention if necessary.
4.2 Most Important Symptoms/Effects, Acute and Delayed: See Section 2 and 11
4.3 Indication of any Immediate Medical Attention and Special Treatment Needed: No data available SECTION 5: FIRE-FIGHTING MEASURES
5.1 Suitable Extinguishing Media: Use water spray, carbon dioxide, dry chemical or alcohol-resistant foam. 5.2 Special Hazards Arising from the Chemical: No data available
5.3 Special Protective Actions for Fire-Fighters: Wear self-contained breathing apparatus and protective clothing if necessary.
SECTION 6: ACCIDENTAL RELEASE MEASURES
6.1 Personal Precautions, Protective Equipment and Emergency Procedures: Use personal protective equipment (see Section 8 for details). Avoid dust formation. Avoid breathing dust.
6.2 Environmental Precautions: Do not let product enter drains or waterways or be discharged to the environment.
6.3 Methods and Materials for Containment and Cleaning Up: Do not dump into any sewers, on the ground or into any body of water. Wet an absorbent material to clean up spill. Place materials in a container for disposal according to location regulations. All disposal practices must be in compliance with all Federal, State and local laws and regulations (see Section 13). Regulations may vary in different locations. Waste characterizations and compliance with applicable laws are the responsibility solely of the waste generator. Keep in suitable, closed containers for disposal.
SECTION 7: HANDLING AND STORAGE
7.1 Precautions for Safe Handling: Avoid skin contact, eye contact and inhalation. Do not ingest. Avoid dust formation. Wear appropriate person protective equipment when handling (see Section 8). Use good laboratory practices when working with chemicals. Wash hands after use.
7.2 Conditions for Safe Storage, including any Incompatibilities: Store upright in a tightly closed container in a dry and well ventilated area.

8.2 Appropriate Engineering Controls: Handle in accordance with good industrial hygiene and safety practices. Wash hands after use, before breaks and at the end of the day.
8.3 Individual Protection Measures, such as Personal Protective Equipment (PPE):
Eye/Face Protection: Safety glasses with side-shields. Eye protection equipment must be tested and approved by appropriate government standards such as NIOSH or EN166.
Skin Protection: Handle with gloves. Gloves should 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 upon glove removal.
Body Protection: Select body protection based on concentration and the amount of chemical that you will be working with. Impervious clothing should be worn.
Respiratory Protection: For nuisance exposures or exposures above applicable limits use respirators tested and approved under appropriate government standards such as NIOSH (US) or EN (EU).
