SECTION 3 – HAZARDS IDENTIFICATION – EMERGENCY OVERVIEW

Appearance : Colorless crystalline powder.
Danger : Causes respiratory tract irritation. Causes skin irritation. Causes eye irritation. May be      fatal if swallowed. May be harmful if absorbed through the skin. Reacts with water. Causes digestive tract irritation. Poison! May cause cardiac disturbances.
Target Organs : Cardiovascular system
Potential Health Effects:
Eye : Causes eye irritation. Contact with dust or vapor may cause systemic toxic effects
Skin : Causes skin irritation. May be fatal if absorbed through the skin. Substance is rapidly absorbed through the skin.

SECTION 7 – HANDLING AND STORAGE

Handling : Wash thoroughly after handling. Wash hand before eating. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid breathing dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Empty containers retain product residue, ( liquid and/ or vapor), and can be dangerous. Do nor pressurize, cut, weld, braze, solder, drill, grind, or expose such container to heat, sparks or open flames. Keep container tightly closed.
Storage : Store in a cool, dry, well – ventilated area away from incompatible substances. Keep away from water. Do not store in metal containers. Keep containers tightly closed.

SECTION 8 – EXPODURE CONTROLS, PERSONAL PROTECTION

Engineering Controls : Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below recommended exposure limits.
