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.  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 severe irritation to the eye causing pronounced 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.  Inhalation of high concentrations of gas/vapor causes lung irritation with coughing and nausea, central nervous depression with headache and dizziness, slowing of reflexes, fatigue and inco-ordination.  WARNING: Intentional misuse by concentrating/inhaling contents may be lethal.  

CHRONIC HEALTH EFFECTS

  There has been concern that this material can cause cancer or mutations, but there is not enough data to make an assessment.  

  Principal routes of exposure are usually by inhalation of vapor/spray mist and skin contact/eye contact.  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.  WARNING: Aerosol containers may present pressure related hazards.
