PERSONAL PROTECTIVE EQUIPMENT
Eyes and Face: Safety goggles
Respiratory: Use local exhaust ventilation to reduce airborne concentrations. Whenadequate ventilation is not available, wear a respirator approved for protection against
inorganic dust
Protective Clothing: Gloves (Nitrile) and suitable protective clothing (typically longsleeve shirt and pants)
Work Hygienic Practices: Quick-drench eyewash and safety shower

immediately.

Remove to fresh air. If
breathing discomfortoccurs and persists, seea medical doctor. If
breathing has stopped,
give artificial respirationand see a physician
immediately.

FIRE FIGHTING• Lithium hydroxide monohydrate is noncombustible.
• If lithium hydroxide monohydrate is involved in fire fighting activities any run-off should becontained as it will potentially be of high pH.
• Wear full protective clothing and self-contained breathing apparatus (SCBA) for fire fighting toguard against possible exposure to lithium hydroxide monohydrate.
