PRODUCT USE

Acrylic structural adhesive. 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 plastic cement", "solvent-type adhesive joining cement", "acrylic structural
adhesive"

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.  Ingestion may result in nausea, abdominal irritation, pain and vomiting.  Considered an unlikely route of entry in commercial/industrial environments.  

EYE

  This material can cause eye irritation and damage in some persons.  The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

SKIN

  This material can cause inflammation of the skin oncontact in some persons.  Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions.  Toxic effects may result from skin absorption.  The material may cause severe 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. Repeated exposures may produce severe ulceration.  

INHALED

  Inhalation may produce health damage*.  The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress.  Inhalation hazard is increased at higher temperatures.  Inhalation exposure may cause susceptible individuals to show change in heart beat rhythm i.e. cardiac arrhythmia. Exposures must be terminated.  Acute intoxication by halogenated aliphatic hydrocarbons appears to take place over two stages. Signs of a reversible narcosis are evident in the first stage and in the second stage signs of injury to organs may become evident, a single organ alone is (almost) never involved.  Depression of the central nervous system is the most outstanding effect of most halogenated aliphatic hydrocarbons. Inebriation and excitation, passing into narcosis, is a typical reaction. In severe acute exposures there is always a danger of death from respiratory failure or cardiac arrest due to a tendency to make the heart more susceptible to catecholamines (adrenalin).  

CHRONIC HEALTH EFFECTS

  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  There is ample evidence that this material can be regarded as being able to cause cancer in humans based on experiments and other information.  

  Principal routes of exposure are usually by skin contact/absorption and inhalation of vapor.  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  Dichloromethane is stored in body fat and metabolized to carbon monoxide, which reduces the oxygen carrying capacity of blood.  Methylene chloride causes liver and kidney damage in test animals and hence  exposing persons with a history of impaired liver function and / or renal  disorders is not advised.  Two epidemiological studies of workers exposed to methylene chloride have  been published. An excess of pancreatic tumours was noted in one study.  Chronic exposure to methylene chloride (approximately 30-120 ppm TWA)  did not appear to provide evidence for increased mortality risk for lung  cancer and cardiovascular disease.
