Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WESTOX SAME DAY SEALER

NFPA

PRODUCT USE

Same day sealer for sprayed, stencilled concrete and cementitious base products. 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

"acrylic sealer", Westocks, Westoks, (misspelling)

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.  Ingestion may result in nausea, pain, vomiting. Vomit entering the lungs by aspiration may cause potentially lethal chemical pneumonitis.  

EYE

  This material can cause eye irritation and damage in some persons.  The material may produce severe irritation to the eye causing pronounced inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  Skin contact with the material may be harmful; systemic effects may resultfollowing absorption.  This material can cause inflammation of the skin oncontact in some persons.  Toxic effects may result from skin absorption.  Open cuts, abraded or irritated skin should not be exposed to this material.  The material may accentuate any pre-existing skin 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

  The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.  Inhalation hazard is increased at higher temperatures.  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.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by skin contact/absorption and inhalation of vapor.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  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.
