contact with skin and if swallowed.
Flammable.
Harmful to aquatic organisms.

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 material may produce severe irritation to the eye causing pronounced inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis.  

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.  Toxic effects may result from skin absorption.  The material may cause 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.  

INHALED

  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.  Dichloromethane is stored in body fat and metabolized to carbon monoxide, which reduces the oxygen carrying capacity of blood.  Xylene is a central nervous system depressant.  Inhalation hazard is increased at higher temperatures.  Toxic effects are increased by consumption of alcohol.  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.  If exposure to highly concentrated solvent atmosphere is prolonged this may lead to narcosis, unconsciousness, even coma and possible death.  

CHRONIC HEALTH EFFECTS

  Principal routes of exposure are usually by skin contact/absorption and inhalation of vapor.  Chronic solvent inhalation exposures may result in nervous system impairment and liver and blood changes. [PATTYS].  Prolonged or continuous skin contact with the liquid may cause defatting with drying, cracking, irritation and dermatitis following.  Dichloromethane exposures cause liver and kidney damage in animals and this justifies consideration before exposing persons with a history of impaired liver function and/or renal disorders.  Small excess risks of spontaneous abortion and congenital malformation  was reported amongst women exposed to xylene in the first trimester of  pregnancy. In all cases however the women had also been exposed to other  substances. Evaluation of workers chronically exposed to xylene has  demonstrated a lack of genotoxicity. Exposure to xylene has been  associated with increased risks of haemopoietic malignancies but, again  simultaneous exposure to other substances (including benzene) complicate  the picture. A long-term gavage study of mixed xylenes (containing 17%  ethyl benzene) found no evidence of carcinogenic activity in rats and  mice of either sex.
