Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WATTYL DIMET KILLRUST OHMCOTE PART A

NFPA

PRODUCT USE

Electrical resistance coating. Part A or Base of a 2 pack urethane coating system.
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. Application is usually by spray atomisation in a
ventilated spray booth, after viscosity reduction with thinner. Refer also to protective
measures for the other component used with the product. Read both MSDS before using; store
and attach MSDS together. The material when ready for use, i.e. with 2 parts mixed
together, CONTAINS free organic isocyanate. Application requires control measures, special
precautions and use of personal protective gear. [APMF].

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.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  There is some evidence to suggest that this material can causeeye irritation and damage in some persons.  The liquid may produce eye discomfort and is capable of causing temporary impairment of vision and/or transient eye inflammation, ulceration.  The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  The material is not thought to produce adverse health effects or skin irritation following contact (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  The liquid may produce skin discomfort following prolonged contact. Defatting and/or drying of the skin may lead to dermatitis.  Toxic effects may result from skin absorption.  Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.  Bare unprotected skin should not be exposed to this material.  The material may accentuate any pre-existing dermatitis condition.  The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin.  

INHALED

  Inhalation may produce health damage*.  There is some evidence to suggest that this material, if inhaled, can irritate the throat and lungs of some persons.  Inhalation hazard is increased at higher temperatures.  Sensitization reactions may appear suddenly after repeatedsymptom free exposures.  Inhalation of high concentrations of gas/vapor causes lung irritation with coughing and nausea, central nervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination.  If exposure to highly concentrated solvent atmosphere is prolonged this may lead to narcosis, unconsciousness, even coma and possible death.  Inhalation of vapor may aggravate a pre-existing respiratory condition such as asthma, bronchitis, emphysema.  Acrylic polymer solutions may contain residual traces of odourous acrylic monomers; the amounts remaining in compounded mixtures represents a very low order of exposure, however this may become noticeable with some materials particularly in confined or poorly ventilated spaces.  

CHRONIC HEALTH EFFECTS

  There is some evidence that inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  

  Principal routes of exposure are usually by inhalation of vapor/spray mist and skin contact with liquid.  Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS].  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.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  Persons with a history of asthma or other respiratory problems or are known to be sensitised, should not be engaged in any work involving the handling of isocyanates. [CCTRADE-Bayer, APMF].
