Hazards Summary
Causes changes in psychophysiological tests in acute oral studies of monkeys; Causes kidney and bladder changes in 36-week constant oral studies of rats; [RTECS] Usually contains about 5% water; [NTP] Acceptable daily intake (ADI) of 0-5 mg/kg; [JECFA] The dihydrate is CAS# 6155-57-3; Contains 5-6% water; May cause mechanical eye irritation; [Mallinckrodt Baker MSDS]
Safety & protection
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Nonfire Spill Response
SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
Personal Protective Equipment (PPE)
RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with a combination filter cartridge, i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid gas, SO2 and a high efficiency particulate filter). (NTP, 1992)
