Toxicology information:
No Federal OSHA PEL (29 CFR 1919.1000) or ACGIH TLV Values are established for this chemical. An interim recommended maximum exposure limit of 500 ppm has been established by AlliedSignal Corp. Acute Inhalation: Albino Rats (Spraque-Dawley) 4 hr-LC50=62.000*ppm. Subchronic Inhalation:
Increase cholesterol/decrease body weight 20,000ppm; NOEL 8,000ppm. Oral: non-toxic, >5 mg/Kg bodyweight. Cardiac Sensitization Threshold: 10,000ppm. Teratology, rat-maternal and fetal tox =20,000 ppm; NOEL=8,000 ppm. Teratology, rabbit-slight body weight loss=4,200 ppm; NOEL=1,400 ppm. Reproduction (2 generation ) Rat: Reduced fertility and reduced body weight=20,000 ppm; NOEL=8,000 ppm. Genetic Studies: Ames Assy-Not Active. CHO Call (gas phase)-positive-up to 10%. CHO Cell (liquid phase)-not active-up to 35%. In Vivo mouse micronucleus-not active-up to 36,000 ppm. Delayed (Subchronic & Chronic) Effects: Subchronic: Fischer 344 rats –slightly toxic-20,000 ppm* Chronic Inhalation: 20,000ppm-interim report*. Male rats exposed by inhalation to 5,000 ppm or greater (6 hours/day, 5 days/week for 2years) were found to have a small but statistically significant number of late developing benign testicular tumors. NOEL 1,500 ppm.
Section VII: STORAGE, SPILL AND DISPOSAL INFORMATION
Storage: Store in cool, dry area in closed containers. Keep away from source of
heat, sparks and open flame.Steps to be taken in case Evacuate area absorb spilled liquid with commercial,material is released or spilled: nonflammable absorbent, i.e. sand, vermiculite, remove unprotected personnel, protected personal should remove ignition sources and shut off fire sources, provide ventilation, shovel(spark proof) absorb material into drums and closed. Do not flush to sewer.
Waste Disposal Method: Comply with local regulations. Consult appropriate regulatory agency prior to disposal or discharge of waste material.
Environmental information: Chemical is slightly toxic
Section VIII:SPECIAL PROTECTION INFORMATION
Engineering Controls: Local exhaust ventilation is strongly recommended. Avoid vapour
accumulation in confined spaces.
Respiratory: None required in ventilated work areas.
Ventilation: Adequate.
Protective Gloves: For long repeated contact, Neoprene preferred.
Eye Protection: Chemical protective safety glasses.
Personal Protection Equipment: Avoid all personal contact. Inpervions gloves and goggles should be worn when handling. If ventilation is inadequate, a NIOSH-certified respirator protection for vapor should be worn as appropriate.
Other protective Equipment: None.
Section IX:SPECIAL PRECAUTIONS
Precautions for Handling and Storage: Avoid breathing vapors. Use only with adequate ventilation Avoid lighted cigarettes, flame, welding or hot spots, which may generate toxic decomposition products. Vapors are heavy and may concentrate in low or poorly ventilated areas.
