Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WESTOX WBA HIGH BUILD MEMBRANE WHITE AND COLOURS

NFPA

PRODUCT USE

Acrylic finishing coat for exterior surfaces. Apply by brush, hand roller or spray
atomisation. 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 latex emulsion membrane finish"

EMERGENCY OVERVIEW

RISK

Harmful in contact with skin.
Toxic: danger of very serious irreversible effects through inhalation, in
contact with skin and if swallowed.
Harmful to aquatic organisms.

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, abdominal irritation, pain and vomiting.  

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.  

SKIN

  Skin contact with the material may be harmful; systemic effects may resultfollowing absorption.  The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  

INHALED

  The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified using animal models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an occupational setting.  Inhalation hazard is increased at higher temperatures.  Minor but regular methanol exposures may effect the central nervous system, optic nerves and retinae. Symptoms may be delayed, with headache, fatigue, nausea, blurring of vision and double vision. Continued or severe exposures may cause damage to optic nerves, which may become severe with permanent visual impairment even blindness resulting. WARNING: Methanol is only slowly eliminated from the body and should be regarded as a cumulative poison which cannot be made non-harmful [CCINFO].  Content of ammonia is low and is not considered a health hazard under good working conditions, however continuous long term working in confined and poorly ventilated areas may cause irritation response, sore eyes/nose.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by skin contact with the material and inhalation of vapor.  Prolonged or repeated skin contact may cause drying with cracking,irritation and possible 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.  Acrylic polymer emulsions 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.
