  • First Aid Measures

    Inhalation:

    If inhaled, remove to fresh air. If not, breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.


    Skin Contact:

    Remove any contaminated clothing. Wash skin with soap or mild detergent and water for at least 15 minutes. Get medical attention if irritation develops or persists. Wash clothing before re-use.


    Eye contact:

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


  • Fire Fighting Measures

    Fire:

    Not considered to be a fire hazard.

    Explosion:

    Not considered to be an explosion hazard.

    Fire Extinguishing Media:

    Use any means suitable for extinguishing surrounding fire.

    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.

  • Accidental Release Measures

    Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust.


  • Handling and 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); observe all warnings and precautions listed for the product.


    8.Exposure Control/Personal Protection

    Airborne Exposure Limits.

    -OSHA Permissible Exposure Limit (PEL);

    15mg/m3 total dust, 5mg/m3 respirable fraction for nuisance dust;

    -ACGITI Threshold Limit Value (TLV);

    10mg/m3 total dust containing no asbestos and <1% crystalline silica for Particulates Not Otherwise Classified (PNOC).

    Ventilation System:

    A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally pretaned because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document. Industrial Ventilation, A Manual of Recommended Practices, most recent edition for details.

    Personal Respirators (NIOSH Approved)

    If the exposure limit is exceeded and engineering controls are not feasible, a half face-piece particulate respirator (NIOSH type N95 or better filter) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified consignments of instances where the exposure levels are not known, use a full-face piece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.


    Skin Protection:

    Wear protective gloves and clean body-covering clothing.


    Eye Protection:

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