TC-1630 PART A

5. Fire-fighting measures
Suitable extinguishing media: Water spray, carbon dioxide, dry chemical, or foam.
Hazardous combustion products: Carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons, and hydrogen cyanide.
Fire fighting procedures: Cool fire exposed containers with water spray. Remove containers from the fire area if possible. Do not release runoff
from fire control methods to sewers or waterways.
Fire fighting equipment: Firefighters should wear positive pressure self-contained breathing apparatus (SCBA) and consider use of unmanned
hose holders or monitor nozzles for fighting large fires.
Sensitivity to static discharge: This material can accumulate static charges which can cause an incendiary electrical discharge.
6. Accidental release measures
Small spill: Evacuate unnecessary personnel from the spill area. Wear necessary personal protective equipment (PPE) as specified in the SDS or
the site emergency response plan. Eliminate all sources of ignition. Ensure adequate ventilation. Dike and contain spill. Prevent product from
entering drains or waterways. Absorb with non-combustible material (such as sand, earth, diatomaceous earth, or vermiculite) and transfer to a
container for disposal according to local/national regulations.
Environmental precautions
Water spill: Do not discharge into drains, surface waters, or groundwater.
General procedures: Refer to section 8 of SDS for personal protection details.
Release notes: Composition and extent of any spill should be evaluated against local regulations and reported to the proper agencies, if necessary.
7. Handling and storage
General procedures: Keep away from sources of ignition. Avoid contact with eyes, skin and clothing. Use only with adequate ventilation. Avoid
breathing vapor over open containers. Avoid open container exposure to damp air. Avoid breathing aerosols, mists, and vapors.
Precautions for safe handling: Use appropriate personal protective equipment as specified in Section 8. Handle in a well-ventilated area. Handle
and use in a manner consistent with good industrial/manufacturing techniques and practices.
Conditions for safe storage: Store in a dry and well-ventilated place, away from excessive heat in the original or similar container. Avoid sources
of ignition and incompatible materials. Protect from freezing. Containers should be tightly sealed to prevent contamination with foreign
materials. Avoid unnecessary contact.
Storage temperature: 65-80 F (18-27 C)
Shelf life: 3 months from date of shipment under manufacturers recommended storage conditions.

Appropriate engineering controls: Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels
below recommended exposure limits.
Individual protection measures, such as personal protective equipment
Eye / face protection: Safety goggles or glasses are recommended. Plastic face shields should be used for complete face protection to protect
against possible splashing or spraying of material. ANSI Z87.1 or approved equivalent.
Skin protection – hand protection: Chemical-resistant gloves and chemical goggles, face-shield, and synthetic apron or coveralls should be
used to prevent contact with eyes, skin, or clothing. Wear nitrile or neoprene gloves. Chemical resistant gloves lined with polyethylene offer
maximum protection.
Respiratory protection: Exhaust ventilation recommended. An organic vapor cartridge or fresh air supplied respirator (NIOSH approved) may
be necessary for certain applications. Consider the type of application, environmental concentrations, and other materials being used
concurrently when determining respirator use and selection. Observe OSHA regulations for respirator use (29 CFR 1910.134).
Skin protection – other: Protective clothing should be selected and used in accordance with “Guidelines for the Selection of Chemical
Protective Clothing” published by ACGIH.
Occupational hygiene practices: Contaminated clothing should be changed and washed before reuse. Eating, drinking and smoking in immediate
work area should be prohibited. Wash hands before eating.
Other use precautions: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Training is
important. Follow all label precautions.

Stability and reactivity Reactivity: Hazardous reactions will not occur under normal transport or storage conditions. Chemical stability: This product is stable under normal ambient conditions of temperature and pressure. Conditions to avoid: High temperatures, moisture, and ignition sources. Possibility of hazardous reactions: Reaction with water produces carbon dioxide. Exothermic reaction with materials containing active hydrogen groups. The reaction becomes progressively more vigorous and can be violent at higher temperatures if the miscibility of the reaction partners is good or is supported by stirring or by the presence of solvents. MDI is insoluble with, and heavier than water and sinks to the bottom but reacts slowly at the interface. A solid water-insoluble layer of polyurea is formed at the interface by liberating carbon dioxide gas. Hazardous decomposition products: Carbon monoxide, carbon dioxide, nitrogen oxides, hydrocarbons, and hydrogen cyanide. Incompatible materials: Water, amines, acids, bases, and strong oxidizing agents. 11.
