4. First aid measures
Inhalation:
Remove to fresh air.If not breathing, give artificial respiration. If breathing is difficult,give Oxygen. Get medical attention.
Ingestion:
Wash out mouth with water provided person is conscious. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of soap and water. Remove contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse.
Eye Contact:

Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper Eyelids occasionally. Get medical attention immediately.

 

5. Fire fighting measures
Conditions to Avoid:
Avoid excess dust in the atmosphere since this is an explosion hazard in the presence of Electrical sparks and static discharges. Keep away from heat, sparks and flames. Suitable extinguishing media:
For small fires, use media such as “alcohol” foam, dry chemical, or carbon dioxide. For large Fires, apply water from as far as possible. Use very large quantities of water applied as a mist or Spray; solid streams of water may be ineffective. Cool all affected containers with flooding Quantities of water.
Explosion:
Not considered to be an explosion hazard. While fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.
Special hazards in fire:
Emit toxic fumes under fire conditions.
Required special protective equipment for fire-fighters:
Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and Eyes.

 

6. Accidental release measures

Personal precautions:
Wear self-contained breathing apparatus,rubber boots and heavy rubber gloves.
Environmental precautions:
Ventilate area and wash spill site after material pickup is complete.
Methods for clearing:
Sweep up,place in bag and hold for waster disposal.Avoid raising dust.

 

7. Handling and Storage

Storage:
Keep in a tightly closed container,stored in a cool,dry,ventilated area.Protect against physical damage.Containers of this material may be hazardous when empty since they retain product residues (dust,solids);Keep far away from various erodes.
Handling:
Avoid contact with skin and eyes.Wear impervious gloves and chemical splash goggles. Handle gently to avoid spilling and leaking.

 

8. Exposure Controls

Engineering Controls:
Safety shower and eye bath.Use nonsparking tools.Mechanical exhaust required.

Personal protection equipment:

For conditions of use where exposure to the dust or mist is apparent,a half-face dust/mist respirator may be worn.For emergencies or instances where the exposure levels are not known,use a full-face positive-pressure,air-supplied respirator.WARNING:Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.

Skin protection: 

Wear impervious protective clothing,including boots,gloves,lab coat,apron or coveralls, as appropriate,to prevent skin contact.

Eye protection:

Use chemical safety goggles.Maintain eye wash fountain and quick-drench facilities in work area.

Hygiene Measures:

Wash thoroughly after handling.
