Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

WACKER ELASTOSIL E43 TRANSPARENT

NFPA

PRODUCT USE

A silicone elastomer. 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. Material cures /
solidifies by reacting with atmospheric moisture and this process generates irritating
acetic acid vapor.

SYNONYMS

"acetic cure silicone sealant"

EMERGENCY OVERVIEW

RISK

Irritating to eyes.

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.  Smoothing the sealant with saliva wet finger may introduce sealant into the mouth. Safer alternates should replace this poor work practice.  Small amounts may be highly irritating to sensitive mouth parts and in extreme produce small blisters but no toxic effects are known.  Ingestion may result in nausea, abdominal irritation, pain and vomiting.  

EYE

  This material can cause eye irritation and damage in some persons.  The vapour when concentrated has pronounced eye irritation effects and this gives some warning of high vapour concentrations. If eye irritation occurs seek to reduce exposure with available control measures, or evacuate area.  Irritating to eyes.  

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.  Open cuts, abraded or irritated skin should not be exposed to this material.  The material may accentuate any pre-existing skin condition.  

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 of vapor may result in nausea, headache.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by skin contact with the uncured material and with vapor from the curing material.  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.
