Storage

Conditions Keep container tightly closed until used. Store in dark colored or opaque containers between 0°C and 50°C in a dark, well-ventilated place. Storage under 30°C is recommended. Do not store in unlined metal containers. Open containers slowly and carefully as there may be some pressure buildup. If product is in vented drums, keep drums upright to prevent leakage of material through the vent. 9. SAFE HANDLING & USE INFORMATION Respiratory Protection In processes where mists or vapors may be generated, a NIOSH/MSHA jointly approved respirator is advised in the absence of proper environmental controls. Eye Protection Wear chemical splash goggles where there is a potential for eye contact. Use safety glasses with side shields under normal use conditions. Hand Protection: Ventilation Rubber or neoprene, to prevent skin contact. In processes where mists or vapors may be generated, proper ventilation must be provided in accordance with good ventilation practices. Other Protective Equipment Eye wash; safety shower, protective clothing (long sleeves, coveralls or other, as appropriate), to prevent skin contact. 10.
