HEALTH & SAFETY INFORMATION

• IDLH: 15 mg/m ³

• Odor threshold: 0.25 mg/m ³ Odor is not a reliable indicator of the presence of toxic amounts of vapor.

• OSHA Table Z-1 Air Contaminant

• Chemical protective clothing is recommended because vapor and liquid can be dermally absorbed and may contribute to systemic toxicity. Poisonous. The dust or aerosol irritates the eyes, skin, and respiratory tract. High levels of exposure may cause death. Contact with eyes or skin may cause severe burns, blindness. May affect the central nervous system, causing fatigue, hyper-excitability, and narcosis; the effects may be delayed. Long-term, this chemical may affect the central nervous system, resulting in fatigue, the inability to concentrate, and loss of coordination.

Exposure Limits:

• ACGIH TLV: 0.05 ppm/0.25 mg/m ³ TWA; 0.15 ppm/0.75 mg/m ³ (skin) STEL

• OSHA PEL: 0.05 ppm/0.25 mg/m ³ TWA; 0.15 ppm/0.75 mg/m ³ (skin) STEL
