| Decomposition |
Solvent vapors exposed to open flames, welding arcs and open electric heating coils |
Decomposition of solvent will form a number of toxic compounds and may also create corrosive conditions in the dry cleaning plant. Pungent odors will be noted. |
Avoid using any open gas-fired equipment, welding arcs and electric heating coils in the dry-cleaning room unless adequate ventilation is employed. See Vent Pipe Corrosion. |
| Vapor |
Spills, leaks and solvent saturated garments |
While odor is not a reliable measure of vapor concentration, it can serve as a warning that unsafe concentrations may exist. Repeated or prolonged exposure of the vapors can dull the ability to detect the odor of low concentrations. Odor, therefore, is not an accurate measure of vapor concentration and should not be relied upon. |
Do not tolerate or become indifferent to a continuing solvent odor. If there is even a slight trace of odor, look for leaks or other sources of solvent vapors. See Federal NESHAPS, weekly leak test requirements, and/or request leak check report form #100-06217-599 from your Dow distributor. Accurately measure vapor concentrations in the air. CAUTION: excessive exposure to perchloroethylene may be recognized by one or more of the following symptoms:
- light-headedness;
- impaired judgment;
- loss of inhibitions;
- giddiness and "drunkenness."
Other symptoms may include stinging sensations in the eyes, nose and throat. There may also be headache, nausea, dizziness or unconsciousness.
ALL AFFECTED PERSONS should move immediately away from the contaminated area to a source of fresh air. Seek medical attention. |
