Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

K+W KIWODUR 1000HMT HARDENER

NFPA

PRODUCT USE

One component of a two- part adhesive. Requires that the two parts be mixed by hand or
mixer before use, in accordance with manufacturers directions. Mix only as much as is
required. Do not return the mixed material to the original containers. The use of a
quantity of material in an unventilated or confined space may result in increased exposure
and an irritating atmosphere developing.Before starting consider control of exposure by
mechanical ventilation.

SYNONYMS

Sericol, "polyisocyanate adhesive", HMT

Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

May cause SENSITIZATION by inhalation and skin contact.
HARMFUL - May cause lung damage if swallowed.
Irritating to eyes, respiratory system and skin.
Highly flammable.
Vapors may cause dizziness or suffocation.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Ingestion may result in nausea, pain, vomiting. Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  This material can cause eye irritation and damage in some persons.  The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  This material can cause inflammation of the skin oncontact in some persons.  Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions.  Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.  Toxic effects may result from skin absorption.  Open cuts, abraded or irritated skin should not be exposed to this material.  

INHALED

  Inhalation may produce health damage*.  If inhaled, this material can irritate the throat andlungs of some persons.  Inhalation hazard is increased at higher temperatures.  Acute effects from inhalation of high vapor concentrations may be chest and nasal irritation with coughing, sneezing, headache and even nausea.  

CHRONIC HEALTH EFFECTS

  Inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  

  Principal routes of exposure are usually by skin contact/absorption inhalation of vapor.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  Sensitization reactions may appear suddenly after repeatedsymptom free exposures.  Sensitization may give severe responses to very low levels of exposure, i.e. hypersensitivity. Sensitized persons should not be allowed to work in situations where exposure may occur.  Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS].  As with any chemical product, contact with unprotected bare skin; inhalation of vapor, mist or dust in work place atmosphere; or ingestion in any form, should be avoided by observing good occupational work practice.
