5. HUMAN HEALTH DATA:

ROUTE (S) OF ENTRY:
Inhalation; Skin Contact; Skin Absorption; Eye Contact
HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE:
ACUTE INHALATION
HDI vapors or mist at concentrations above the TLV or MGL can irritate (burning sensation) the mucous membranes in the respiratory tract (nose, throat, lungs) causing runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function (breathing obstruction.). Persons with a preexisting, nonspecific bronchial hyperreactivity can respond to concentrations below the TLV or MGL with similar symptoms as well as an asthma attack. Exposure well above the TLV or MGL may lead to bronchitis, bronchial spasm and pulmonary edema (fluid in lungs). These effects are usually reversible. Chemical or hypersensitive pneumonitis, with flu-like symptoms (e.g., fever, chills) has also been reported.
CHRONIC INHALATION
As a result of previous repeated overexposures or a single large dose, certain individuals will develop Isocyanate sensitization (chemical asthma) which will cause them to react to a later exposure to Isocyanate at levels well below the TLV or MGL. These symptoms, which include: chest tightness, wheezing, cough, shortness of breath or asthmatic attack, could be immediate or delayed up to several hours after exposure. Similar to many non-specific asthmatic responses, there are reports that once sensitized an individual can experience these  symptoms upon exposure to dust, cold air or other irritants. This increased lung  sensitivity can persist for weeks and in severe cases for several years. Chronic overexposure to Isocyanate has also been reported to cause lung damage, including decrease in lung function, which may be permanent. Sensitization may be either temporary or permanent.
ACUTE SKIN CONTACT
Isocyanate react with skin protein and moisture and can cause irritation. Symptoms of skin irritation may be reddening, swelling, rash, scaling or blistering. Some persons may develop skin sensitization from skin contact. Cured material is difficult to remove.
CHRONIC SKIN CONTACT
Prolonged contact with the Isocyanate can cause reddening, swelling, rash, scaling or blistering. In those who have developed a skin sensitization, these symptoms can develop as a result of contact with very small amounts of liquid material or even as a result of vapor-only exposure.
ACUTE EYE CONTACT
Liquid, aerosols and vapors of this product are irritating and can cause pain, tearing, reddening and swelling accompanied by a stinging sensation and/or a feeling like that of fine dust in the eyes.
CHRONIC EYE CONTACT
May result in corneal opacity (clouding of the eye surface).
ACUTE INGESTION 
Can result in irritation and possible corrosive action in the mouth, stomach tissue and digestive tract.
CHRONIC INGESTION
None determined.

EXPOSURE LIMITS :
Not established for product as a whole. Refer to Section II for exposure limits of hazardous constituents. The Mobay Guideline Level of 0.5 mg/m3 - TWA and 1.0 mg/m3 - STEL for the Homopolymer of HDI and 0.02 ppm ceiling for HDI monomer are internal guides based on limited data; they are provided as guides pending the review of future data.

6. EMERGENCY AND FIRST AID PROCEDURES:

FIRST AID FOR EYES:
Flush with clean, lukewarm water (low pressure) for at least 15 minutes while holding eyelids open. Refer individual to physician or ophthalmologist for immediate follow-up.
FIRST AID FOR SKIN:
Remove contaminated clothing immediately. Wash affected areas thoroughly with soap and water. Wash contaminated clothing thoroughly before reuse. For severe exposures, get under safety shower after removing clothing, then get medical attention. For lesser exposures seek medical attention if irritation develops or persists.
FIRST AID FOR INHALATION:
Move to an area free from risk of further exposure. Administer oxygen or artificial respiration as needed. Obtain medical attention. Asthmatic-type symptoms may develop and  may be immediate or delayed up to several hours. Treatment is essentially symptomatic. Consult physician.
FIRST AID FOR INGESTION:
DO NOT INDUCE VOMITING. Give a glass of milk or water to drink. DO NOT GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON. Consult a physician.
NOTE TO PHYSICIAN:
Eyes: Stain for evidence of corneal injury. If cornea is burned, instill antibiotic/steroid preparation frequently. Workplace vapors could produce reversible corneal epithelial edema impairing vision. 
Skin: This product is a known skin sensitizer. Treat symptomatically as for contact dermatitis or thermal burn. 
Ingestion: Treat symptomatically. There is no specific antidote. Inducing vomiting is contraindicated because of the irritating nature of the product. Inhalation: This product is a known pulmonary sensitizer. Treatment is essentially symptomatic. An individual having a dermal or pulmonary sensitization reaction to this material must be removed from any further exposure to any Isocyanate.

7. EMPLOYEE PROTECTION RECOMMENDATIONS:

REQUIRED WORK/HYGIENE PROCEDURES:
Precautions must be taken so that persons handling this product do not breathe the vapors or have it contact the eve or skin. In spray operations, protection  must be afforded against exposure to both vapor and spray mist.
EYE PROTECTION REQUIREMENTS: 
Liquid chemical goggles or full-face shield. Contact lenses should not be worn.
SKIN PROTECTION REQUIREMENTS: 
Permeation resistant gloves (butyl rubber, nitrile rubber). Cover as much of the exposed skin area as possible with appropriate clothing. If skin creams are used, keep the area protected only by the cream to a minimum.
RESPIRATORY/VENTILATION REQUIREMENT: 
A respirator that is recommended or approved for use in Isocyanate containing environments (air purifying or fresh air supplied) may be necessary. Consider type of application and environmental concentrations. Observe OSHA regulations for respirator use (29 CFR 1910.134)
Exhaust ventilation sufficient to keep the airborne concentrations of HDI and polyisocyanate below their respective TLV and MGL must be utilized. Exhaust air may need to be cleaned by scrubbers or filters to reduce environmental contamination
NOTE ON ODOR WARNING PROPERTIES:
Pure Isocyanate materials have odor thresholds that are higher than the TLV, PEL or MGL. Thus, if a vapor/particulate air-purifying respirator has exceeded its service life, breakthrough of the filter can result in exposure over the allowable limit without the wearer being able to smell the Isocyanate. However, when a polyurethane coating system contains organic solvents, the wearer of a vapor particulate respirator will be warned of filter breakthrough by the odor of solvents before being exposed to Isocyanate because: 
1) organic solvents have low odor thresholds, and 
2) testing has demonstrated that solvents break through filters before Isocyanate do. SPRAY APPLICATION: A. Good industrial hygiene practice dictates that when Isocyanate based coatings are spray applied, some form of respiratory protection should be worn. During the spray application of 
organic solvent containing coatings systems, the use of a positive pressure 
supplied air respirator is mandatory when: - the airborne Isocyanate concentrations are  not known, or - the airborne HDI monomer concentrations exceed 0.05 ppm (10 times the  TLV) or the polyisocyanate (polymeric, oligomeric) concentrations exceed 5 mg/m3  averaged over 8 hours or 10 mg/m3 averaged over 15 minutes (10 times the MGL) or - spraying is performed in a confined space or in an area with limited ventilation. A  properly fitted air-purifying (combination organic vapor and particulate) respirator, proven by test to be effective in containing-containing spray paint environments,  will provide adequate protection when: 
- the airborne HDI monomer concentrations are known to be below 0.05 ppm (10 times the TLV), and 
- the polyisocyanate  (polymeric, oligomeric) concentrations are known to be below 5 mg/m3 averaged over 8  hours or 10 mg/m3 averaged over 15 minutes (10 times the MGL). B. During the spray application of a coatings system NOT containing organic solvents a positive pressure supplied air respirator is mandatory when: 
- the airborne Isocyanate concentrations are  unknown,  or 
- the airborne Isocyanate monomer concentration exceeds the TLV of 0.005 
PPM, or 
-the polyisocyanate (polymeric, oligomeric) concentration exceeds the MGL of 0.5 mg/m3 averaged over 8 hours, or - operations are performed in a confined space or in an area with limited ventilation. Under any other circumstances, during spray application of a coatings system NOT containing organic solvents, good industrial hygiene practice dictates that when Isocyanate based coatings are spray applied some form of respiratory protection should be worn. NON-SPRAY OPERATIONS: A. Even during  non-spray operations such as mixing, batch making, brush or roller application, etc., depending on the conditions (for example, heating of material or  application to a hot substrate), it is possible to be exposed to airborne Isocyanate vapors. Therefore, when the coatings system contains solvents and will be applied in a non- spray manner, a positive pressure supplied air respirator must be worn when: - the airborne concentrations are unknown; or - the airborne HDI monomer concentrations exceed 0.05 ppm (10 times the TLV), or - the airborne concentrations of the polyisocyanate (polymeric, oligomeric) exceed 5 mg/m3 averaged over 8 hours or 10 mg/m3 averaged over 15 minutes  (10 times the MGL), or - operations are performed in a confined space or in an area  with limited ventilation. At least an air purifying (organic vapor) respirator is required when: - the airborne concentrations of the HDI monomer exceed the  TLV of 0.005 ppm but are below 0.05 ppm (10 times the TLV), or - the airborne concentrations of the polyisocyanate (polymeric, oligomeric exceed the MGL  of 0.5 mg/m3 averaged over 8 hours, or 1.0 mg/m3 averaged over 15 minutes but are  below 10 mg/m3 (10 times the MGL). B. During non-spray operations using a 
solvent-free coatings system, a positive pressure supplied air respirator is mandatory  when: - the airborne Isocyanate concentrations are unknown, or - the airborne  Isocyanate monomer concentrations exceed the TLV of 0.005 ppm, or - the polyisocyanate (polymeric, oligomeric) concentrations exceed the MGL of 0.5 mg/m3 averaged  over 8 hours, or 1.0 mg/m3 averaged over 15 minutes, or - operations are performed  in a confined space or in an area with limited ventilation.
MONITORING:
Refer to Patty's Industrial Hygiene and Toxicology-Volume 1 (3rd edition) Chapter 17 and volume III (1st edition) Chapter 3-for guidance concerning appropriate air sampling strategy to determine airborne concentrations.
MEDICAL SURVEILLANCE:
Medical supervision of all employees who handle or come in contact with this product is recommended. This should include pre employment and periodic medical examinations with respiratory function tests (FEV, FVC as a minimum). Persons with asthma-type conditions, chronic bronchitis, other chronic respiratory diseases or recurrent skin eczema or sensitization should be excluded from working wit Isocyanate. Once a person is diagnosed as sensitized to an Isocyanate, no further exposure can be permitted.
ADDITIONAL PROTECTIVE MEASURES:
Safety showers and eyewash stations should be available. Educate and train employees in safe use of product. Follow all label instructions. For additional information, see Mobay's "Health and Safety Information for Hexamethylene Diisocyanate Based  Polyisocyanates"..

12. ANIMAL TOXICITY DATA:

TOXICITY DATA FOR: HDI homopolymer materials except where indicated
ACUTE TOXICITY
ORAL LD50: 
Estimated to be greater than 10000 mg/kg (rats). (Based on the results of actual tests conducted using specific HDI-homopolymer products.)
DERMAL LD50:
Estimated to be greater than 5000 mg/kg (rabbits).
(Based on the results of actual tests conducted using specific HDI-homopolymer products.)
INHALATION LC50:
Lower respiratory (pulmonary) irritant. LC50 values range from 137-1150 mg/m3 were obtained in rats exposed to aerosols. (4H exp.)
EYE EFFECTS:
Severe irritant capable of inducing corneal injury (Rabbit); maximum primary eve irritation score: 54.G/110 for a 24 hr. exposure.
SKIN EFFECTS:
Moderate irritant; primary dermal irritation score:3.4/8.0 (rabbit)
SENSITIZATION :
Pulmonary and dermal sensitizer in humans. Delayed  dermal sensitization. was observed in guinea pigs. However, the respiratory sensitization potential of Desmodur N-3300 assessed in guinea pigs was negative. Evidence exists that cross-sensitization between HDI and other Isocyanate, particularly hydrogenated MDI and TDI, can occur.
OTHER ACUTE EFFECTS:
AMES TEST: Negative for Desmodur TI-100 (100 solids material).
SUB CHRONIC TOXICITY:
Rats exposed to a HDI homopolymer (isocyanurate type, specifically, the solvent-free Desmodur N-3300), at 4.3, 14.7 and 89.8 mg/m3 for three weeks (6 hrs/day, S days/wk) exhibited respiratory distress and inflammation of the nasal passages at 14.7 mg/m3 and above. At the 89.8 mg/m3 inflammatory  lesions at many sites of the lungs were also observed. The No Observable Effect Level (NOEL) was 4.3 mg/m3. Rats were also exposed t an HDI homopolymer (isocyanurate type, specifically, the solvent-free product Desmodur N-3300), for 13 weeks (6 hrs/day, 5 days/wk) at aerosol concentrations of 0.5, 3.3 and 26.4 mg/m3. Body weight gain of male rats of the 26.4 mg/m3 group were slightly reduced toward the end of the study. The lung weight to body weight ratio was significantly increased in the male and female rats of the 26.4 mg/m3 group.
Histopathoiogic diagnosis of these animals revealed inflammatory changes 
and formation of fibrous tissue at the point of injury in the respiratory tract. In addition, the lung function tests at the end of the, study provided evidence of a chronic obstructive lung disorder in rats of the 26.4 mg/m3 group. The No Observable Effect Level (NOEL) in this study is considered to be 3.3 mg/m3.
OTHER TOXICITY DATA: 
Mice were exposed to a liquid aerosol of an HDI homopolymer (isocyanurate type, specifically, the  solvent-free product Desmodur N-3300), mixed with acetone for three hours. The Irritation potential expressed as the RD50 (the concentration which is predicted to reduce the 
respiratory rate 50%) was 20.8 mg/m3 (95% confidence interval = '_8.3 to 23.9 mg/m3).  Pulmonary (lung) irritation was observed first, followed by sensory (eve, nose, and throat) irritation.
