Section 3: Hazards Identification

Potential Acute Health Effects:

Very hazardous in case of eye contact (irritant). Hazardous in case of skin contact (irritant), of inhalation. Slightly

hazardous in case of ingestion. Inflammation of the eye is characterized by redness, watering, and itching.

Potential Chronic Health Effects:





The substance is toxic to kidneys, liver.

Repeated or prolonged exposure to the substance can produce target organs damage.


Section 4: First Aid Measures

Eye Contact:

Check for and remove any contact lenses. Immediately flush eyes with running water for at least 15 minutes,

keeping eyelids open. Finish by rinsing thoroughly with running water to avoid a possible infection. Cold water

may be used.

Skin Contact:

After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin

with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin.

Cold water may be used. Cover the irritated skin with an emollient. If irritation persists, seek medical attention.

Wash contaminated clothing before reusing.

Serious Skin Contact:

Wash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate

medical attention.

Inhalation: Allow the victim to rest in a well ventilated area. Seek immediate medical attention.

Serious Inhalation: Not available.


Do not induce vomiting. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible

indication that the toxic material was ingested; the absence of such signs, however, is not conclusive. Loosen

tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth

resuscitation. Seek immediate medical attention.

Serious Ingestion: Not available.

Section 6: Accidental Release Measures

Small Spill:

Dilute with water and mop up, or absorb with an inert dry material and place in an appropriate waste disposal

container. If necessary: Neutralize the residue with a dilute solution of acetic acid. Finish cleaning by spreading

water on the contaminated surface and dispose of according to local and regional authority requirements.

Large Spill:

Flammable liquid.

Keep away from heat. Keep away from sources of ignition. Stop leak if without risk. Absorb with DRY earth, sand or

other non-combustible material. Do not touch spilled material. Prevent entry into sewers, basements or confined

areas; dike if needed. Eliminate all ignition sources. Neutralize the residue with a dilute solution of acetic acid.

Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local



Section 7: Handling and Storage


Keep away from heat. Keep away from sources of ignition. Ground all equipment containing material. Do not

ingest. Do not breathe gas/fumes/ vapour/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


Alkalis may be stored in heavy duty gauge steel containers. 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).


Section 8: Exposure Controls/Personal Protection

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.


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.
