DOT-KennzeichnungFlammable Liquid Poison
BrandgefahrenThis chemical is combustible. (NTP, 1992)
BrandpotenzialMODERATE FIRE RISK
GesundheitsgefahrenSYMPTOMS: Symptoms of exposure to this chemical may include local irritation of the eyes and skin.
GefahrenübersichtExternal application to rabbit eyes scored 7 on a scale of 1-10 (10 being most severe)Emergency treatment: Morpholine[HSDB] A mild skin and severe eye irritant[RTECS] See Morpholine.
Reaktive GruppeAmines, Phosphines, and Pyridines
Reactivity AlertsHighly Flammable
Reactivity Profile2,6-DIMETHYL MORPHOLINE reacts with oxidizing agents (NTP, 1992). Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.
Air and Water ReactionsHighly flammable. Very slightly water soluble.
NFPA Hazard Classification2 - Materials that, under emergency conditions, can cause temporary incapacitation or residual injury.2 - Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur. Materials would not under normal conditions form hazardous atmospheres with air, but under high ambient temperatures or under moderate heating could release vapor in sufficient quantities to produce hazardous atmospheres with air.0 - Materials that in themselves are normally stable, even under fire conditions.
Hazard Classes and CategoriesFlam. Liq. 3 (100%)
BrandbekämpfungFires involving this material should be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Erste HilfeEYES: 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.
Brandbekämpfungsverfahren"ALCOHOL" FOAM
Freisetung ohne BrandSMALL SPILLS AND LEAKAGE: If you should spill this chemical, use absorbent paper to pick up all liquid spill material. Seal the absorbent paper, as well as any of your clothing which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Wash any surfaces you may have contaminated 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.
Isolation and EvacuationExcerpt from ERG Guide 131 [Flammable Liquids - Toxic]:
Personal Protective Equipment (PPE)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)
