4. FIRST AID MEASURES

Inhalation: Remove to fresh air. In case of shortness of breath, give oxygen. Immediate medical 

attention is required. 

Skin contact: Wash off immediately with plenty of water for at least 15 minutes. Take off all 

contaminated clothing immediately. If skin irritation persists, call a physician. Wash contaminated 

clothing before re-use. Do not take clothing home to be laundered. 

Eye contact: Rinse immediately with plenty of water for at least 15 minutes. If eye irritation persists, 

consult a specialist. 

Ingestion: Never give anything by mouth to an unconscious person. Do NOT induce vomiting. Call a 

physician immediately. If a person vomits when lying on his back, place him in the recovery position. 

Notes to physician: Bronchial constriction may develop after extensive exposure to isocyanates, 

even in individuals who have not been shown to be previously sensitized. 

5. FIREFIGHTING MEASURES

Flash point > 93 °C ( > 199.40 °F ) SETAFLASH CLOSED CUP

Lower explosion limit Not Applicable

Upper explosion limit Not Applicable

Suitable extinguishing media:Foam

Carbon dioxide (CO2)

Dry powder

Thermal decomposition During a fire, irritating and highly toxic gases and/or fumes may be 

generated during combustion or decomposition.

Combustion Products: Hydrogen Cyanide

Carbon monoxide

Carbon dioxide

Nitrogen oxide (NO2)

Specific hazards during firefighting: Do not allow run-off from fire fighting to enter drains or water 

courses. Closed containers may explode when heated or contents contaminated with water. 

Special protective equipment for firefighters: In the event of fire, wear self-contained breathing 

apparatus. 

Further information: Fire residues and contaminated fire extinguishing water must be disposed of in 

accordance with local regulations.

Collect contaminated fire extinguishing water separately. This must not be discharged into drains.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions

Ventilate the area.

Refer to protective measures listed in sections 7 and 8.

MATERIAL IS A POTENTIAL SENSITIZER.
CR 9-101

Page 4 of 8 Revision Date 04/10/2012

Environmental precautions

Try to prevent the material from entering drains or water courses.

Do not contaminate surface water.

Methods for cleaning up

Ventilate the area.

Evacuate personnel to safe areas.

Floor may be slippery; use care to avoid falling.

Contain spills immediately with inert materials (e.g., sand, earth).

Transfer liquids and solid diking material to separate suitable containers for recovery or disposal.

Additional advice: 

No conditions to be specially mentioned.

7. HANDLING AND STORAGE

Handling

Avoid contact with skin and eyes. For personal protection see section 8. CONTAINERS MAY BE 

HAZARDOUS WHEN EMPTY. Since emptied containers retain product residue follow all MSDS and 

label warnings even after container is emptied. 

Storage

Storage conditions: Keep container tightly closed in a dry and well-ventilated place. 

Further information on storage conditions: Keep from freezing. 

Storage temperature: 10 - 37.8 °C (50 - 100.0 °F)

Further information:

This material is a potential skin sensitizer. See SECTION 8, Exposure Controls/Personal Protection, 

prior to handling.

ppm

Hexamethylene diisocyanate NIOSH REL C 0.14 mg/m3 0.02 ppm

Exposure controls

Engineering measures: Use local exhaust ventilation with a minimum capture velocity of 100 ft/min. 

(0.5 m/sec.) at the point of vapor evolution. Refer to the current edition of Industrial Ventilation: A 

Manual of Recommended Practice published by the American Conference of Governmental Industrial 

Hygienists for information on the design, installation, use, and maintenance of exhaust systems. 

Hygiene measures: Keep container closed when not in use. Shower or bathe at the end of working. 
CR 9-101

Page 5 of 8 Revision Date 04/10/2012

Protective measures: Facilities storing or utilizing this material should be equipped with an eyewash 

facility and a safety shower. 

Individual protection measures

Eye/face protection: Tightly fitting safety goggles Eye protection worn must be compatible 

with respiratory protection system employed.

Skin protection

Hand protection: Chemical-resistant gloves should be worn whenever this material is 

handled. The glove(s) listed below may provide protection against permeation. 

(Gloves of other chemically resistant materials may not provide adequate protection): 

4H Glove (Trademark of Safety 4 A/S of Denmark) butyl-rubber Gloves should be 

removed and replaced immediately if there is any indication of degradation or 

chemical breakthrough. Before removing gloves clean them with soap and water. 

NOTE: Material is a possible skin sensitizer. 

Other protection: Avoid all skin contact. Selection of specific personal protective 

equipment such as long sleeves, safety glasses with side shields, face shield, safety 

shoes, boots, apron, or full body suit will depend on the task. 

Respiratory protection: A respiratory protection program meeting OSHA 1910.134 and ANSI 

Z88.2 requirements or equivalent must be followed whenever workplace conditions warrant a 

respirator‟s use. None required if airborne concentrations are maintained below the exposure 

limit listed in Exposure Limit Information. Above the exposure limit: Wear a properly fitted 

NIOSH approved (or equivalent) self-contained breathing apparatus in the pressure demand 

mode, OR full-facepiece, airline respirator in the pressure demand mode with emergency 

escape provision.
