4First-aid measures

First Aid Measures

Inhalation: Move the person to fresh air and keep comfortable for breathing. If breathing is difficult or symptoms persist, call a POISON CENTER or doctor.
Skin: Take off contaminated clothing. Wash the skin with plenty of soap and water. If irritation or a rash develops, get medical advice.
Eyes: Rinse cautiously with water for several minutes. Remove contact lenses if present and easy to do; continue rinsing. If eye irritation persists, get medical advice.
Ingestion: Rinse mouth. Do not induce vomiting. Call a POISON CENTER or doctor if you feel unwell.

Most Important Symptoms And Effects

skin redness or irritation; eye redness, watering and irritation; coughing and irritation of the nose and throat after inhaling dust; nausea, vomiting and other systemic effects after ingestion.

Likely Routes Of Exposure

Inhalation of dust, skin and eye contact when the vial is opened or the powder is weighed; ingestion through contaminated hands; accidental injection when reconstituted solutions are drawn into syringes.

5Fire-fighting measures

Fire Fighting Information: Combustible organic solid; finely divided powder may form dust clouds. Not flammable in the quantities supplied.

6Accidental release measures

Spill And Clean Up Procedures: 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.

7Handling and storage

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.
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.
Storage Temperature: −20 °C (sealed vial), desiccated and protected from light; 2–8 °C acceptable for short periods
Incompatible Materials: Strong oxidizing agents; strong acids/bases (generic for quaternary quinolinium iodides; iodide can be oxidized to iodine)
