Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WATTYL ACID CAT SEALER PART A

NFPA

PRODUCT USE

A two- pack acid- catalysed clear sealer for interior timber. 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. 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

"spray timber", "sealer coating", alkyd, urea, "formaldehyde urethane"

Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

Risk of serious damage to eyes.
Limited evidence of a carcinogenic effect.
May impair fertility.
May cause harm to the unborn child.
HARMFUL - May cause lung damage if swallowed.
Harmful by inhalation, in contact with skin and if swallowed.
Irritating to respiratory system and skin.
Highly flammable.
Vapors may cause dizziness or suffocation.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual.  Not a likely route of entry into the body in commercial or industrial environments. The liquid may produce considerable gastrointestinal discomfort and be harmful or toxic if swallowed. Ingestion may cause nausea, pain and vomiting. Vomit entering the lungs by aspiration can cause inflammation of the lungs, which can lead to death.  

EYE

  If applied to the eyes, this material causes severe eye damage.  The liquid produces a high level of eye discomfort and is capable of causing pain and severe conjunctivitis. Corneal injury may develop, with possible permanent impairment of vision, if not promptly and adequately treated.  The material may produce moderate eye irritation leading to 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.  Bare unprotected skin should not be exposed to this material.  Toxic effects may result from skin absorption.  Exposure limits with "skin" notation indicate that vapor and liquid may be absorbed through intact skin. Absorption by skin may readily exceed vapor inhalation exposure. Symptoms for skin absorption are the same as for inhalation. Contact with eyes and mucous membranes may also contribute to overall exposure and may also invalidate the exposure standard.  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

  If inhaled, this material can irritate the throat andlungs of some persons.  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

  There has been concern that this material can cause cancer or mutations, but there is not enough data to make an assessment.  There is some evidence that inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population.  Ample evidence exists from experimentation that reduced human fertility is directly caused by exposure to the material.  Ample evidence exists, from results in experimentation, that developmental disorders are directly caused by human exposure to the material.  

  Principal routes of exposure are usually by inhalation of vapor and skin contact with the material.  Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS].  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  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.  One ingredient of the product has caused skin sensitization reactions, shown as localized reddening and hives, or may produce respiratory sensitization characterized by asthma-  like symptoms and runny nose.
