| Indication of immediate medical attention | Treat symptomatically. Show this safety data sheet to the attending physician. No specific antidote is known; monitor for the effects described in Section 11. |
5Fire-fighting measures
| Suitable extinguishing media | Water spray, carbon dioxide, dry chemical or alcohol-resistant foam. Use measures appropriate to the surrounding fire. |
|---|---|
| Unsuitable extinguishing media | None known. Do not use a high-pressure water jet on powders (dust dispersion). |
| Specific hazards | Combustible organic solid; finely divided powder may form dust clouds. Not flammable in the quantities supplied. Thermal decomposition may release carbon monoxide, carbon dioxide and nitrogen oxides. |
| Protective equipment for fire-fighters | Self-contained breathing apparatus and full protective clothing. Prevent run-off from entering drains. |
6Accidental release measures
| Personal precautions | Wear the protective equipment in Section 8. Keep unprotected people away. Avoid dust formation and inhalation of dust. |
|---|---|
| Environmental precautions | Do not allow material to reach drains, surface water or soil. Quantities supplied are small; collect for disposal. |
| Methods for cleaning up | Avoid dust formation. Dampen spilled powder with water, wipe up with absorbent material, place in a sealed container for disposal and clean the area with water and detergent. Decontaminate surfaces with 70% alcohol or detergent and water. |
7Handling and storage
| Precautions for safe handling | Open vials only in a clean area. Avoid generating or inhaling dust; weigh or reconstitute inside a ventilated enclosure when the full contents are handled as a dry powder. Reconstitute by adding diluent slowly to the vial wall; do not shake. Wash hands after handling. Do not eat, drink or smoke in the handling area. Follow the precautionary statements in Section 2. |
|---|---|
| Conditions for safe storage | Store the sealed vial at the temperature stated in Section 9 (typically −20 °C for peptides, 2–8 °C for proteins), desiccated and protected from light. Allow the vial to reach room temperature before opening to avoid condensation. Reconstituted solutions: 2–8 °C, protected from light; use within the period established by your laboratory. Keep the container tightly closed and labelled, out of reach of unauthorised persons (store locked up). |
| Storage temperature | 2–8 °C (sealed vial); −20 °C for long-term storage; protected from light and moisture |
