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. If experiencing respiratory symptoms (wheezing, shortness of breath), 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.
Injection: For an accidental needle-stick: wash the site with soap and water, do not squeeze, cover with a dressing and seek medical advice; report the incident according to your laboratory's sharps procedure.
General: If exposed or concerned, get medical advice. Show this safety data sheet to the doctor. Pregnant or nursing laboratory staff should avoid exposure.

Most Important Symptoms And Effects

wheezing, chest tightness or asthma-like symptoms after inhalation in sensitised individuals.

Likely Routes Of Exposure

Accidental needle-stick injection; skin and eye contact from splashes; ingestion is unlikely.

5Fire-fighting measures

Fire Fighting Information: Aqueous solution containing 0.9% benzyl alcohol; not flammable and does not support combustion.

6Accidental release measures

Spill And Clean Up Procedures: Absorb small spills with paper towel or an inert absorbent, place in a sealed container for disposal and clean the area with water and detergent. Pick up broken glass with tongs or forceps, never by hand.

7Handling and storage

Safe Handling: Handle the device as a sharp: never recap or reuse needles, keep fingers away from the needle, and discard used devices into a rigid sharps container. Avoid splashes to eyes and skin. Wash hands after handling.
Safe Storage: Store at 2–8 °C in the original carton, protected from light. Do not freeze; discard if the solution has frozen or is discoloured or cloudy. Once in use, keep the device capped between uses.
Storage Temperature: 2–8 °C, protected from light; do not freeze
Incompatible Materials: reducing agents

8Exposure controls / personal protection

Occupational Exposure Limits: Benzyl alcohol: no OSHA PEL, ACGIH TLV or NIOSH REL; AIHA WEEL 10 ppm (44 mg/m³) 8-h TWA. Present at 0.9%.
