Fire FightingFires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

First Aid · 1 Eintrag

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 · 1 Eintrag

SMALL SPILLS AND LEAKAGE: If you should spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION. You should then use absorbent paper to pick up liquid spill material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent-wash contaminated surfaces with 60-70% methanol followed by washing 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) · 1 Eintrag

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)

Beschreibungα-Cyclodextrine (α-CD) is a cyclic oligosaccharide derived from corn (Trade name: Mirafit fbcx, ArtJen Complexus, Windsor, Ontario, Canada). It has been shown to form a stable complex with dietary fat. This complex is resistant to normal lipolytic hydrolysis by lipases and thereby reduces the absorption and bioavailability of dietary fat[1].
