Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

HB FULLER EASY SEAL MULTIPURPOSE

NFPA

PRODUCT USE

Sealant for the building industry. Apply directly from the cartridge using a caulking gun.
The use of a quantity of material in an unventilated or confined space may result in
increased exposure and an irritating atmosphere developing.

SYNONYMS

"silicone sealant"

Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

May cause SENSITIZATION by skin contact.
Irritating to eyes and skin.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  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.  

EYE

  This material can cause eye 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

  This material can cause inflammation of the skin oncontact in some persons.  The material may accentuate any pre-existing dermatitis condition.  

INHALED

  The cured solid material is inert and represents a low order of hazard.  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].  Inhalation of vapor may aggravate a pre-existing respiratory condition such as asthma, bronchitis, emphysema.  

CHRONIC HEALTH EFFECTS

  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  

  Principal routes of exposure are usually by skin contact with the material and inhalation of vapor from the curing material.  Material cures / solidifies by reacting with atmospheric moisture and this process generates irritating vapor.  Silica in this material is bound in a rubbery soft matrix and does notpresent an inhalation exposure hazard.  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.  Methyl ethyl ketoxime (MEKO) is formed during the curing process of this  product. Male rodents exposed to MEKO vapour throughout their lifetime  developed liver cancer. Additional testing is planned by the MEKO supplier  to determine any relevance to humans. until more data is known, exposure  levels should be maintained as low as achievable.  A small amount of methanol and methylethylketoxime is released on curing.  Inhalation of methanol vapour at any concentration may lead to severe  poisoning similar to that encountered in instances of oral ingestion.  Over heated material (i.e. above 180 C.) decomposes and releases highly  irritating formaldehyde gas
