Description of necessary first-aid measures
Fresh air, rest. Half-upright position. Refer immediately for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention .
Most important symptoms/effects, acute and delayed
This material is highly toxic by inhalation and moderately toxic through the skin. (Non-Specific -- Isocyanates) People with skin or respiratory problems should avoid exposure. (EPA, 1998)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Isocyanates, aliphatic thiocyanates, and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
If material on fire or involved in fire: Do not extinguish fire unless flow can be stopped. Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources.
Specific hazards arising from the chemical
When heated to decomposition, it emits toxic fumes of nitrogen oxides. (EPA, 1998)
Special protective actions for fire-fighters
Use water spray, foam, powder, carbon dioxide.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Treat remaining liquid with a mixture of ammonia (4-8%), detergent (2%), and water. Do NOT let this chemical enter the environment.
Environmental precautions
Personal protection: chemical protection suit including self-contained breathing apparatus. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Treat remaining liquid with a mixture of ammonia (4-8%), detergent (2%), and water. Do NOT let this chemical enter the environment.
Methods and materials for containment and cleaning up
Decontamination of spilled isocyanates and disposal of isocyanate waste are best conducted by using aqueous ammonia (3-8% concentrated ammonia solution in 90-95% water with 0.2-5% liquid detergent) or aqueous sodium carbonate (5-10% sodium carbonate in 90-95% water and 0.2-5% liquid detergent). An alcoholic solution (50% ethanol, isopropyl alcohol, or butanol; 45% water; and 5% concentrated ammonia) may be preferred because of the low miscibility of isocyanates with water. Isocyanates
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Separated from bases, acids, alcohols, amines, amides, phenols, mercaptans and food and feedstuffs. Keep in a well-ventilated room. Well closed. Cool. Dry. Store in an area without drain or sewer access.Isocyanates are transported in railroad tank cars, tank trucks, tanks in ships, containers, and drums. They are stored in steel tanks and processed in steel equipment. For long-term storage stainless steel is recommended. To avoid contamination by atmospheric moisture, a dry air or inert gas blanket is essential. Isocyanates
