| DOT-Kennzeichnung | Combustible Liquid |
| Brandgefahren | Flash point data for this chemical are not available. It is probably combustible. (NTP, 1992) |
| Gesundheitsgefahren | Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: |
| Gefahrenübersicht | Highly flammableMay polymerize[CAMEO] A skin and strong eye irritant[Sigma-Aldrich MSDS] See 3,4-Epoxy-1-butene. |
| Reaktive Gruppe | Hydrocarbons, Aliphatic Unsaturated |
| Reactivity Alerts | Highly Flammable |
| Reactivity Profile | Epoxides are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts. |
| Air and Water Reactions | Highly flammable. |
| Hazard Classes and Categories | Flam. Liq. 2 (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 | STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992) |
| Isolation and Evacuation | Excerpt from ERG Guide 128 [Flammable Liquids (Water-Immiscible)]: |
| Personal Protective Equipment (PPE) | RECOMMENDED RESPIRATOR: When working with this chemical, wear a NIOSH-approved full face chemical cartridge respirator equipped with the appropriate organic vapor cartridges. If that is not available, a half face respirator similarly equipped plus airtight goggles can be substituted. However, please note that half face respirators provide a substantially lower level of protection than do full face respirators. (NTP, 1992) |
