Section 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Not available.
Potential Health Effects
Eye:
May cause mild eye irritation.
Skin:
Dimethyl phthalate has low acute toxicity in experimental animals exposed by the oral, inhalation and dermal routes. In other words, it is not acutely toxic. However, repeated and/or prolonged skin contact may result in the absorption of harmful amounts. Dimethyl phthalate was not a sensitizer in guinea pigs and has not been reported to be a sensitizer from its use during WWII as an insect repellent; however, it has been called an allergen in one Russian study of human patch testing.
Ingestion:
Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause central nervous system depression.
Inhalation:
Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. May cause respiratory tract irritation. Exposure to dimethyl phthalate occurs from spray or mist, rather than from the vapor, unless heat is applied. Intermittent exposure produced blood, liver and kidney changes in rats.
Chronic:
Some adverse reproductive effects were seen in animal studies. Few defects occurred when rats were given injections of dimethyl phthalate intraperitoneally on gestational days 5, 10 and 15.

Section 4 - FIRST AID MEASURES
Eyes: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical aid if irritation develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.

Section 5 - FIRE FIGHTING MEASURES
General Information:
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.
Extinguishing Media:
In case of fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.

Section 6 - ACCIDENTAL RELEASE MEASURES
General Information: Use proper personal protective equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container.
