Section 1 - CHEMICAL PRODUCT AND COMPANY IDENTIFICATION

PRODUCT NAME

VERNON BENSHOFF KOLDMOUNT MONOMER LIQUID

NFPA

PRODUCT USE

Liquid component of casting acrylic . Requires Koldmount Powder hardener. 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. 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

"Methyl Methacrylate monomer Acrylic misspelling Coldmount cold Kold Mount"

Section 2 - HAZARDS IDENTIFICATION

CANADIAN WHMIS SYMBOLS

EMERGENCY OVERVIEW

RISK

Danger of cumulative effects.
May cause SENSITIZATION by skin contact.
Toxic by inhalation, in contact with skin and if swallowed.
Irritating to eyes, respiratory system and skin.
Highly flammable.
Vapors may cause dizziness or suffocation.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 40 gram may be fatal or may produce serious damage to the health of the individual.  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 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 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.  

SKIN

  Skin contact with the material may produce toxic effects; systemic effectsmay result following absorption.  This material can cause inflammation of the skin oncontact in some persons.  

INHALED

  If inhaled, this material can irritate the throat andlungs of some persons.  Vapors potentially cause drowsiness and dizziness*.  Inhalation hazard is increased at higher temperatures.  Acute effects from inhalation of high vapor concentrations may be chest and nasal irritation with coughing, sneezing, headache and even nausea.  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 inhalation of vapor and skin contact with the material.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.  Sensitization may give severe responses to very low levels of exposure, i.e. hypersensitivity. Sensitized persons should not be allowed to work in situations where exposure may occur.  Prolonged and repeated methyl methacrylate exposures may cause liver and  kidney changes.  [ROHM & HAAS]
