4. n Propanol – FIRST AID MEASURES
Eye Contact
Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes.
Immediate medical attention is required.
Skin Contact
Wash off immediately with plenty of water for at least 15 minutes. Get medical attention immediately if symptoms occur.

Move to fresh air. If breathing is difficult, give oxygen. Do not use mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artificial respiration with a respiratory medical device. Get medical attention immediately if symptoms occur.
Serious Inhalation:
Evacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is
difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek medical attention.

6. n Propanol – ACCIDENTAL RELEASE MEASURES
Personal Precautions
Use personal protective equipment. Remove all sources of ignition. Take precautionary measures against static discharges. Avoid
contact with skin, eyes and clothing.
Environmental Precautions
Should not be released into the environment.
Methods for Containment and Clean Up
Remove all sources of ignition. Soak up with inert absorbent material. Take precautionary measures against static discharges. Keep
in suitable and closed containers for disposal.

7. HANDLING AND STORAGE
Precautions:
Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not ingest. Do not breathe
gas/fumes/ vapor/spray. In case of insufficient ventilation, wear suitable respiratory equipment If ingested, seek medical advice
immediately and show the container or the label. Avoid contact with skin and eyes Keep away from incompatibles such as oxidizing
agents, acids.
Storage:
Flammable materials should be stored in a separate safety storage cabinet or room. Keep away from heat. Keep away from sources
of ignition. Keep container tightly closed. Keep in a cool, well-ventilated place. Ground all equipment containing material. A
refrigerated room would be preferable for materials with a flash point lower than 37.8°C (100°F).

8. EXPOSURE CONTROLS AND PERSONAL PROECTION
Engineering Controls:
Provide exhaust ventilation or other engineering controls to keep the airborne concentrations of vapors below their respective
threshold limit value. Ensure that eyewash stations and safety showers are proximal to the work-station location.
Personal Protection:
Splash goggles. Lab coat. Vapor respirator. Be sure to use an approved/certified respirator or equivalent. Gloves.
Personal Protection in Case of a Large Spill:
Splash goggles. Full suit. Vapor respirator. Boots. Gloves. A self contained breathing apparatus should be used to avoid inhalation of
the product. Suggested protective clothing might not be sufficient; consult a specialist BEFORE handling this product.
