4. First Aid Measures

Inhalation:

Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.

Swallow:

wash stomach by 2.5-3% sodium sulphate solution, catharsis. Get medical attention.

Skin Contact:

Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes.

Eye Contact:

Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally.

5. Fire Fighting Measures

hazard character: contact with fire, high heat can fire and explore, can bleed toxic gas through high heat or fire. With dense sulphuric acid can emit smoke. If high heat container inner pressure increase, can split and explore.

Harmful fire fruit;

carbon oxides, carbon monoxide, and nitrogen oxides

Fire Extinguishing Media:

Cut off giveaway source, cool container with water, extinguish with carbon dioxide spume. Special Information:

In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. Water spray may be used to protect person who plug leak.

6. Accidental Release Measures

Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective equipment as specified in Section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate container or absorb with an inert material (e. g., vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer! If a leak or spill has not ignited, use water spray to disperse the vapors, to protect personnel attempting to stop leak, and to flush spills away from exposures.

7. Handling and Storage

handling attention: tight while producing, handle tightly, pay attention ventilation. Storage attention; Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Storage and use areas should be No Smoking areas. Use non-sparking type tools and equipment, including explosion proof ventilation, observe all warnings and precautions listed for the product. Establish warning label in storage place, prohibit unnecessary person coming in.

8. Exposure Controls/Personal Protection

Project control: tight while producing, handle tightly, pay attention ventilation.

Personal Respirators:

If the exposure limit is exceeded, wear a supplied air, full-face piece respirator, air lined hood, or full-face piece self-contained breathing apparatus.

Body protection: Wear impervious protective clothing.

Hand protection: wear protective gloves.

Eye Protection:

Use chemical safety goggles and/or a full face shield where splashing is possible.

Maintain eye wash fountain and quick-drench facilities in work area.

Other Control Measures:

Provide clean work clothes daily to workers who regularly use this material. Direct workers to shower before changing into street clothes. No smoking in working place.
