1. IDENTIFICATION OF THE SUBSTANCE/PREPARATION AND OF THE COMPANY/UNDERTAKING

 

chat-dong-ran

 

This material is severely corrosive to the eyes and may cause delayed keratitis. The normally prescribed 15 minute eye irrigation after exposure may be difficult because of the severe pain. The prior installation of a topical ocular anesthetic is essential to facilitate a comprehensive ocular lavage. If swallowed, do not induce vomiting. Give patient plenty of water to drink. Ingestion of this corrosive material may result in severe ulceration, inflammation, and possible perforation of the upper alimentary tract, with hemorrhage and fluid loss. Aspiration of this material during induced emesis can result in severe lung injury. Contact a Poison Control Center for additional treatment information. Treat any additional effects

symptomatically.

3. HAZARDS IDENTIFICATION

 

May cause fire.

 

Harmful if swallowed.

 

Causes burns.

 

4. FIRST AID MEASURES

 

Symptoms and effects


Harmful if swallowed. Causes burns. Causes injury to the cornea and eyelids. Risk of serious damage to eyes.

 

First aid

 

General

 

Call a physician immediately.

 

Inhalation


Remove to fresh air. If not breathing, give artificial respiration. Oxygen may additionally be given, by trained personnel, if it is available. Get medical attention immediately.

 

Skin


Immediately start continuous flushing of skin with water for at least 15 minutes, while removing contaminated clothing and shoes. Get medical attention immediately. Wash clothing before reuse. Thoroughly clean or destroy contaminated shoes.

 

Eye


Immediately start continuous flushing of eyes with water for at least 15 minutes. If easy to do, contact lenses should be removed during the flushing, by trained personnel. Hold the eyelids apart during the flushing to ensure rinsing the entire surface of the eye and lids with water. Get medical attention immediately.

 

Ingestion


DO NOT induce vomiting. Get medical attention immediately by calling a physician or a poison control center. If victim is conscious and alert, give a cupful of water. Never give anything by mouth to an unconscious or convulsing person. If vomiting occurs, the patient should lie on their left side while vomiting to reduce the risk of aspiration.

 

Advice to physician


This material is severely corrosive to the eyes and may cause delayed keratitis. The normally prescribed 15 minute eye irrigation after exposure may be difficult because of the severe pain. The prior installation of a topical ocular anesthetic is essential to facilitate a comprehensive ocular lavage. If swallowed, do not induce vomiting. Give patient plenty of water to drink. Ingestion of this corrosive material may result in severe ulceration, inflammation, and possible perforation of the upper alimentary tract, with hemorrhage and fluid loss. Aspiration of this material during induced emesis can result in severe lung injury. Contact a Poison Control Center for additional treatment information. Treat any additional effects symptomatically.

 

 

5. FIRE-FIGHTING MEASURES

 

Extinguishing media


waterspray, alcohol resistant foam, sand, dry chemical powder, CO2.

 

Unsuitable extinguishing media


halones.

 

Special exposure hazards


CAUTION: reignition may occur. Decomposition under effect of heating (See also Section Hazardous decomposition products). If involved in a fire, it will support combustion. Vapours may form explosive mixtures with air. In case of fire and/or explosion do not breathe fumes.

 

Hazardous decomposition/


combustion products Carbon dioxide, Water, Acetic acid, Formic acid, Propanoic acid, Methyl ethyl ketone

 

Protective equipment


Firefighters must wear fire resistant protective equipment. Wear approved respirator and protective gloves

 

Other information


Evacuate all non-essential personnel. Extinguish a small fire with powder or carbon dioxide then apply water to prevent re-ignition. Cool closed containers with water. Water used to extinguish a fire should not be allowed to enter the drainage system or water courses. After a fire, ventilate thoroughly the area and soak with water, clean the walls and metallic surfaces.

 

 

6. ACCIDENTAL RELEASE MEASURES

 

Personal precautions


Do not breathe fumes/vapour. Avoid contact with skin and eyes. For personal protection see Section 8.

 

Environmental precautions


Do not allow to enter drains or water courses.

 

Methods for cleaning up


Stop leakage if possible. Eliminate all sources of ignition, and do not generate flames or sparks. Collect as much as possible in a clean container for (preferable) reuse or disposal. Cover the remainder with inert absorbent (e.g. vermiculite) for disposal. Keep contents moist. The waste should NOT be confined. Flush surroundings with large amounts of water.

 

Other information


CAUTION: reignition may occur. Vapours are heavier than air and may spread along floors. Vapours may travel to a source of ignition and flash back. Evacuate personnel to safe area.

 

7. HANDLING AND STORAGE

 

Handling


Never weigh out in the storage room. When using do not eat, drink or smoke. Do not pipet by mouth. Do not breathe fumes/vapour. Handle in well ventilated areas. Eliminate all sources of ignition, and do not generate flames or sparks.Keep away from reducing agents (e.g. amines), acids, alkalies and heavy metal compounds (e.g. accelerators, driers, metal soaps). Keep product and emptied container away from heat and sources of ignition. Confinement must be avoided. Avoid contact with skin and eyes. Avoid Incompatible materials (See Section 10).

 

Fire and explosion prevention


Use explosion protected equipment. Keep away from sources of ignition - No moking. Vapours are heavier than air and may spread along floors. Use non-sparking tools in area's where explosive vapor air mixtures may occur. Do not cut or weld on or near this container even when empty.

 

Storage requirements


Store in accordance with local/national regulations. Keep away from food, drink and animal feedingstuffs. Store in a dry well ventilated place away from sources of heat and direct sunlight. Store separate from other chemicals. Keep only in the original container. Keep container upright to prevent leakage.

 

Storage


Avoid temperatures below -10 °C. If product freezes or separates, contact Akzo Nobel.

 

For maximum quality store below: 40 °C.

 

Other information


It is recommended to use electrical equipment of temperature group T3. However, autoignition can never be excluded. Wash hands thoroughly after handling or contact. Keep working clothing separately and do not take them home.

 

NR-7-UK-HSE Guidance (07)


A COSHH assessment necessary to ensure compliance.

 

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

 

Engineering controls


Ensure good ventilation and local exhaustion of the working area.

 

Explosion proof ventilation recommended.

 

Personal protection

 

Respiratory


In case of insufficient ventilation wear suitable respiratory equipment (respirator with Filter A).

 

Hand


Wear suitable protective gloves of neoprene or synthetic rubber

 

Eye


Wear eye/face protection.

 

Skin and body


Wear suitable protective clothing

 

Other information


Emergency-shower and facilities for rinsing eyes must be accessible. Launder clothes before reuse.

10. STABILITY AND REACTIVITY

 

 

 

Stability


SADT - (Self accelerating decomposition temperature) is the lowest temperature at which self accelerating decomposition may occur with a substance in the packaging as used in transport. A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can be caused by thermal decomposition at and above the following temperature: 55 °C. Contact with incompatible substances can cause decomposition at or below the SADT 55 °C.

 

Conditions to avoid


Avoid temperatures below -10 °C. To maintain quality store in original closed container below: 40 °C. Confinement must be avoided.

 

Incompatible materials


Avoid contact with rust, iron and Copper. Contact with incompatible materials such as acids, alkalies, heavy metals and reducing agents will result in hazardous decomposition. Do not mix with peroxide accelerators. Use only Stainless steel 316, PVC, polyethylene or glass-lined equipment.

 

polymerization


Polymerization does not occur.

 

Decomposition


Acetic acid, Formic acid, Propanoic acid, Methyl ethyl ketone

 

Other information

 

Emergency procedures will vary depending on conditions. The customer must have an emergency response plan in place. Contact Akzo Nobel for assistance with developing an emergency response plan.
