|
|
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 isocyanates 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 |
|
|
Isocyanates 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. |

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 isocyanates because:
1) organic solvents have low odor thresholds, and
2) testing has demonstrated that solvents break through filters before isocyanates 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 isocyanate-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 preemployment 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
isocyanates. 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

WASTE DISPOSAL METHOD: |
|
Waste must be disposed of in accordance with
federal, state and local environmental control regulations. Incineration
is the preferred method. Empty containers must be handled with care due to
product residue. Decontaminate containers prior to disposal. DO NOT HEAT
OR CUT EMPTY CONTAINER WITH ELECTRIC OR GAS TORCH. (See Section IV and
VIII). |
10. SPECIAL PRECAUTIONS & STORAGE DATA: |
STORAGE TEMPERATURE (MIN/MAX): |
|
-30 F (-34 C)/122 F (50 C) |
SHELF LIFE: |
|
6 months @ 77 F (25 C) after receipt of material
by customer. |
SPECIAL SENSITIVITY: |
|
If container is exposed to high heat, it can be
pressurized and possibly rupture explosively. HDI reacts slowly with water
to form C02 gas. This gas can cause sealed containers to expand and
possibly rupture explosively. |
HANDLING/STORAGE PRECAUTIONS: |
|
Store in tightly closed containers to prevent
moisture contamination. Do not reseal if contamination is suspected. At maximum storage temperatures noted, material
may slowly polymerize without hazard. Ideal storage temperature range for ease of handling is 50-81 F (10-27 C). Avoid
contact with skin and eyes. Employee education and training in the safe use and handling of this product are required under
the OSHA Hazard Communication Standard. |

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
isocyanates, particularly hydrogenated MDI and TDI, can occur. |
OTHER ACUTE EFFECTS: |
|
AMES TEST: Negative for Desmodur TI-100 (100 solids
material). |
SUBCHRONIC 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. |
