Guidance on Safe Use

First-aid measures

Persons using these products should consult a physician or other medical professional if an accident involving these products in injury. Specific first-aid measures are as follows:

Eye Contact: Flush contaminated eye(s) with copious quantities of water. Part eyelids to assure complete flushing. Continue for a minimum of 15 minutes. Repeat for subsequent 15 minutes periods if irritation returns. Seek immediate medical attention.

Skin Contact: Remove contaminated clothing and flush affected areas with large amounts of lukewarm water. Delayed burns may result,seek immediate medical attention.

Inhalation: Get medical aid immediately. Remove form exposure to fresh air immediately. If breathing is difficult, give oxygen. Do NOT use outh-to mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.

Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Possible aspiration hazard. Get medical aid immediately.

Fire-fighting measures

Extinguishing Media: Use water spray (fog), foam or dry chemical.

.Special Fire Fighting Procedures: Fire-fighters should wear appropriate protective equipment and self-contained breathing

apparatus (SCBA) with a full face-piece operated in positive pressure mode.

.Unusual Fire and Explosion Hazards: Extremely flammable in the presence of the following materials or conditions: open

flames, sparks and static discharge and oxidizing materials.

.Explosion Sensitivity to Mechanical Impact: Not available.

.Explosion Sensitivity to Static Discharge: Not available.

Accidental release measures

Release Response: Immediately contact emergency personnel. Stop leak if without risk. Use spark-proof tools and

explosion-proof equipment. Note: see section 1 for emergency contact information and section 13 for waste disposal.

.Measures for environmental protection: Do not allow material to be released to the environment without proper governmental

permits.

Handling and storage

Handling:

.Information for safe handling:

Use only with adequate ventilation. Use explosion-proof electrical (ventilating, lighting and material handling) equipment. Wash

thoroughly after handling. Do not puncture or incinerate container. Use equipment rated for cylinder pressure. Close valve after

each use and when empty.

.Information about fire and explosion protection:

Do not ingest. Keep container closed. Keep away from heat, sparks and flame. To avoid fire, eliminate ignition sources. Protect

cylinders from physical damage; do not drag, roll, slide, or drop. Use a suitable hand truck for cylinder movement.

.Storage:

.Requirements to be met by storerooms and receptacles:

Keep container in a cool, well-ventilated area. Keep container tightly closed and sealed until ready for use. Avoid all possible

sources of ignition (spark or flame). Segregate from oxidizing materials. Cylinders should be stored upright, with valve protection

cap in place, and firmly secured to prevent falling or being knocked over. Cylinder temperatures should not exceed 52℃.

.Further information about storage condition: Store in cool, dry conditions in well sealed containers

Exposure controls / personal protection

.Engineering Controls: Use only with adequate ventilation. Use process enclosures, local exhaust ventilation or other

engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The

engineering controls also need to keep gas, vapor or dust concentrations below any lower explosive limits. Use explosion-proof

ventilation equipment.

.Personal Protective Equipment:

.Protection of Hands: Chemical-resistant, impervious gloves complying with an approved standard should be worn at all times

when handling chemical products if a risk assessment indicates this is necessary.
