    Section 4 — First Aid Measures

    First Aid Procedures

    Eyes

    Move victim away from exposure and into fresh air. Flush eyes with plenty of clean water for at least 15 minutes. If symptoms persist, seek medical attention.

    Skin

    Wash contaminated area thoroughly with mild soap and water. If chemical or solution soaks through clothing, remove clothing and wash contaminated skin. If irritation develops and persists after washing, seek medical attention.

    Inhaled

    If respiratory symptoms develop, move victim away from source of exposure and into fresh air. If symptoms persist, seek medical attention.

    Ingestion

    If large amounts are swallowed, seek emergency medical attention. If possible, do not leave victim unattended and observe closely for adequacy of breathing.
    Note to Physician
    None Known

    Section 5 — Fire Fighting Measures

    Extinguishing Media
    Use extinguishing agent suitable for type of surrounding fire.
    Protection of Firefighters
    Muriate of Potash is non-combustible, however, when this material is subjected to temperatures of 1,500 C (2,732 F) or greater, it may release small amounts of chlorine gas. Positive pressure, self-contained breathing apparatus is required for all firefighting activities involving hazardous materials. Full structural firefighting (bunker) gear is the minimum acceptable attire. The need for proximity, entry, flashover and/or special chemical protective clothing (see Section 8) needs to be determined for each incident by a competent firefighting safety professional. Water used for fire suppression and cooling may become contaminated. Discharge to sewer system(s) or the environment may be restricted, requiring containment and proper disposal of water (see Section 6).

    Section 6 — Accidental Release Measures

    Response Techniques
    Stay upwind and away from spill (dust hazard). Wear appropriate protective equipment, including respiratory protection, as conditions warrant (see Section 8). Prevent spilled material from entering sewers, storm drains, other unauthorized treatment drainage systems, and natural waterways. Notify appropriate federal, state, and local agencies as may be required (see Section 15). Minimize dust generation. Sweep up and package appropriately for disposal. Large spills can harm or kill vegetation.

    Section 7 — Handling and Storage

    Handling
    The use of appropriate respiratory protection is advised when concentrations exceed any established exposure limits (see Section 8). Avoid contact with eyes, skin, and clothing. Wash thoroughly after handling. Wash contaminated clothing or shoes. Use good personal hygiene practices.
    Storage
    Use and store this material in dry, well-ventilated areas. Store only in approved containers. Keep container(s) tightly closed. Keep away from any incompatible material (see Section 10). Protect container(s) against physical damage. Material may absorb moisture from the air.

    Section 8 — Exposure Controls / Personal Protection

    Engineering Controls
    Use process enclosure, general dilution ventilation or local exhaust systems where necessary to maintain airborne dust concentration below the OSHA standards or in accordance with applicable regulations.
    Personal Protective Equipment (PPE)

    Eye/Face

    Approved eye protection to safeguard against potential eye contact, irritation, or injury is recommended.

    Skin

    The use of cloth or leather work gloves is advised to prevent skin contact, possible irritation and absorption.

    Respiratory

    A NIOSH approved air purifying respirator with a type 95 (R or P) particulate filter may be used under conditions where airborne concentrations are expected to exceed exposure limits. Protection provided by air purifying respirators is limited (see manufacturer’s respirator selection guide). Use a positive pressure air supplied respirator if there is potential for uncontrolled release, exposure levels are not known or any other circumstances where air purifying respirators may not provide adequate protection. A respiratory protection program that meets OSHA’s 29 CFR 1910.134 and ANSI Z88.2 requirements must be followed if workplace conditions warrant a respirator.

    Other

    A source of clean water should be available in the work area for flushing eyes and skin. Impervious clothing should be worn as needed.

    General Hygiene Considerations
    Wash thoroughly after handling, Use adequate ventilation
