|---|---|
| Brandgefahren | This chemical is combustible. (NTP, 1992) |
| Gesundheitsgefahren | ACUTE/CHRONIC HAZARDS: This compound may be narcotic in high concentrations. When heated to decomposition it emits toxic fumes. (NTP, 1992) |
| Gefahrenübersicht | A mutagen, tumorigen, and reproductive effectorCauses somnolence in subcutaneous, lethal-dose studies of mice[RTECS] Inhalation of high concentrations may cause narcotic effects[CAMEO] May cause irritation[MSDSonline] |
| Reaktive Gruppe | Carbamates |
| Reactivity Profile | N-METHYLCARBAMIC ACID, ETHYL ESTER is a carbamate ester. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates. |
| Air and Water Reactions | Water soluble. |
| Hazard Classes and Categories | Acute Tox. 3 (100%) |
| Brandbekämpfung | Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992) |
| Erste Hilfe | 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. |
| Freisetung ohne Brand | SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION. Then, 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. |
| 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) |
