  III. Hazards Identification



HMIS Hazard Rating No. 2

PRIMARY ROUTE OF ENTRY: Eye and skin contact, breathing and ingestion.

Symptoms of Exposure



Skin Contact:           Contact may cause moderate skin irritation. In some individuals exposure may result in

                        allergic type symptoms causing rash, itching and hives.

Eyes:                   Contact can cause severe irritation, redness, tearing and blurred vision.





Adurel International, Inc.                          ADUREL U5500                                      Page 1 of 4

Inhalation              Vapors can be irritating to nose and mucous membranes. Exposures may result in

                        tightness or burning in chest, coughing, headache and fatigue. Respiratory sensitivity may

                        result in asthma like symptoms and on subsequent exposure even below the TLV.

Ingestion:              Not expected to be a relevant route of exposure although it can cause gastrointestinal

                        irritation, nausea, vomiting diarrhea and headache.

Chronic                 One scientific study of workers reported that exposure to isocyanate type chemicals

                        resulted in larger declines in lung function compared to other workers.

                        Materials are not known mutagenic, teratogenic, or reproductive health hazards.

  IV. First Aid Measures

Inhalation                   Remove victim from exposure. If difficulty with breathing, administer oxygen and

                             seek medical assistance

Eyes                         Flush eyes with cold water for a minimum of 15 minutes, lifting lower and upper eye

                             lids throughout. Seek immediate medical attention.

Skin                         Immediately remove contaminated clothing. Wash thoroughly with soap and water. If

                             irritation persists seek medical attention. Wash contaminated clothing before reuse.

Ingestion                    Do not induce vomiting, get immediate medical attention, if vomiting occurs

                             spontaneously keep head below hips to prevent aspiration of liquids into lungs. Do

                             not give anything by mouth to an unconscious person

Special Fire & Unusual Hazards Move containers from area if it can be done without risk. Cool fire-

                                  exposed containers with water from the side. As in any fire, wear

                                  NIOSH/MSHA approved, pressure demand self contained breathing

                                  apparatus and full protective gear.



  VI. Accidental Release Measures



Action To Take For Spills/ Leaks: Avoid contact with skin or eyes. Ventilate area, eliminate all sources of

ignition. Wear appropriate protective gear, contain leak or spill, salvage, clean up residue with absorbent

material. This product is heavier than and insoluble in water. Wash down area using a soap solution and

allow 10 minutes to react.

Waste Disposal Method: Handle disposal of waste material in manner which complies with local, state,

province and federal regulation. Landfill if solidified, or incineration at agency approved waste-disposal

facilities.



  VII. Handling And Storage



Average Shelf Life:                                           Refer to Product Data Sheet

Special Instructions                                          Store in a cool dry place.



  VIII. Exposure Controls / Personal Protection



Ventilation: Ventilation is recommended. Air movement must be designed to insure turnover at all

locations in work area to avoid build up of heavy vapors.

Personal Protection Equipment: Do NOT wear contact lenses when working with this material. Use

chemical goggles/safety glasses with side shields and impervious gloves. Wear clothing with long sleeves

and pants. In operations where mists can be generated or the exposure limits for crystalline silica



Adurel International, Inc.                          ADUREL U5500                                       Page 2 of 4

exceeded, wear a NIOSH/MSHA approved dust/fume respirator selected by a technically qualified person

for the specific work conditions. Wear respirator protection whenever airborne concentrations exceed TLV

ceilings or TWA, use NIOSH approved respirators for listed hazard.

Confined spaces, room, or tanks are areas where concern for TLV's is especially important. Reference

OSHA regulation CFR 29 1910.134 for recommended respiratory protection.
