__________________________________________________________________________________________________
Effects of exposure when :
Inhaled : May cause irritation to the nose, throat and respiratory tract and possible sensitization.
In contact with the skin : Prolonged and repeated contact may cause irritation and possible sensitization.
In contact with the eyes : May cause irritation, redness and pain.
Ingested : Ingestion of large amounts may cause gastrointestinal upset and abdominal pain.
Other Health Effects : Human evidence has indicated that this material can cause respiratory sensitization.
Inhalation of isocyanate can result in primary irritation of the respiratory tract, sensitization to isocyanates, and gradual
loss of pulmonary function. Acute exposure to isocyanate is charecterized by the irritation of the respiratory tract causing
runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function. Over exposure may
lead to bronchitis, bronchial spasm and pulmonary edema. Chronic exposure may lead to isocyanate sensitization in
certain individuals with the following symptoms: chest tightness, wheezing, cough, shortness of breathing or asthmatic
attack.
2
The symptoms of the skin irritation due to isocyanate may be reddening, swelling, rash scaling or blistering. Some
individuals may develop skin sensitization with very small amounts of liquid material or even as a result of vapour-only
exposure.
Sensitization is the process whereby o biological change occurs in the individual because of previous exposure to a
substance and, as a result, the individual reacts more strongly when subsequently exposed to the substance. Once
sensitized, an individual can react to extremely low airbone levels, even below the TLV, or to skin contact.

First aid procedures when :
Inhaled : Move victim to fresh air. Stay with victim and have a second rescuer obtain oxygen equipement and call an
ambulance. Oxygen should be administered by trained personnel. Give artificial respiration ONLY if breathing has
stopped. Give cardiopulmonary resuscitation (CPR) if there is no breathing and no pulse. Obtain medical attendion
immediately.
In contact with the skin : Remove contaminated clothing. Wash affected areas with soap and water. If irritation
persists, obtain medical advice immediately.
In contact with the eyes : Immediately flush eyes with running water for a minimun of 20 minutes. Hold eyelids open
during flushing. If irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY.
Ingested : If victim is alert and not convulsing, give 1/2 to 1 glass of water to dilute material. Do not induce vomiting.
If spontaneous vomiting occours, have victim lean forward with head down to avoid breathing in of vomitus, rinse
mouth and administer more water. Obtain medical attention immediately.
Emergency Medical Care : Medical supervision of all employees who handle or come in contact with Isocyanates is
recommended. This should include preemployment and periodic medical examinations with respiratory function tests
(forced expiratory volume, forced vital capacity as a minimum). Persons with asthmatic-type conditions, chronic
bronchitis, other chronic respiratory diseases or recurrent skin eczema or sensitization should be excluded from working
with idocyanates. Once a person is diagnosed as sensitized to an isocyanate, no further exposure should be permitted.

PREVENTATIVE MEASURES
Recommendations listed in this section indicate the type of equipment which will provide protection against over exposure
to this product. Conditions of use, adequacy of engineering or other control measures, and actual exposures will dictate the
need for specific protective devices at your workplace.
Engineering Controls : Local exhaust ventilation required.
Respiratory Protection : A NIOSH/MSHA approved air-supplied respirator for concentrations of MDI above 0,02p.p.m.
A NIOSH/MSHA approved air-purifying respirator equipped with organic vapour cartridges for concentrations of MDI
less than 0,02p.p.m.
Skin Protection : Use gloves and protective clothing made from Neoprene.
Eye Protection : Safety glasses with side shields are recommended to prevent eye contact.
Other Personal Protective Equipment : Long-sleeved overalls (preferably heavy cotton), eye protection, protective
gloves (eg.PVC), safety boots. Take all precautions to avoid personal contact. Safety shower and eye wash located close
to chemical exposure area.
Handling Procedures and Equipment : Always dispense isocyanate-based products in a well-ventilated area and while
wearing normal protective equipment. Avoid contact with reacting mix of chemicals. When the product is sprayed or
heated, an approved positive-pressure, supplied-air respirator may be required.
Storage Temperature (en 0C) : 16-38 0C.
Storage Requirements : The recommended storage temperature is 38 0C for bulk storage and 20-25 0C for drum storage.
At temperatures over 40 0C, the vapour pressure increases enough that the product becomes a toxic hazard. Heating also
promotes dimer formation, reducing the reactivity. Low temperatures result in increased viscosity, making handling more
difficult. Padding containers with dry air or nitrogen is recommended to prevent contamination from atmospheric
moisture.
Other Precautions : Use only with adequate ventilation. Avoid breathing vapour. Avoid contact with eyes, skin or
clothing. Wash thoroughly with soap and water after handling. Wash contaminated clothing thoroughly before re-use.
Wear skin, eye and respiratory protection during clean-up of spills. Empty drums should be decontaminated and not
reused. Never heat isocyanates by open flame, hot plates or any other method of direct heating. Sensitized individuals
should be removed from possible further contact. Do not reseal containers of material which have become contaminated
with water.

ENVIRONMENTAL PROTECTION DATA
Steps to be taken in the event of a spill or leak : Collect product for recovery or disposal. For release to land, contain
discharge by constructing dykes or applying inert absorbent; for release to water, utilize damming and/or water diversion
to minimize the spread of contamination. Collect contaminated soil and water, and absorbent for disposal. Notify
applicable government authority if release is reportable or could adversely affect the environment.
Environmental Effects : Fish toxicity for pure MDI : 96 hour TLM greater than = 1 000mg/L (Zebra fish) Spilled
material has an unaesthetic appearance and may be considered a nuisance.
Deactivating Chemicals : A deactivating solution of water (90-95%), concentrated ammonia (8%) or sodium carbonate
(5-10%) and liquid detergent (0,2-2%) may be used with thorough mixing. Allow deactivated material to stand for at least
30 minutes before shovelling into drums. Do not tighten the bungs. Mixing with wet earth is also an effective but slower
method.
Waste Disposal Methods : Dispose of waste material at an approved (hazardous) waste treatment/disposal facility, or at
an approved waste incineration facility in accordance with applicable local, provincial, and federal regulation. Do not
dispose of waste with normal garbage, or to sewer systems.
