galvanized iron, black iron or steel. Aluminum is not generally recommended for storage or handling. Store drums in a cool place (bungs up and closed tightly). Ventilation should be provided at the floor level. Section VIII - Exposure Controls/Personal Protection Exposure Controls Engineering Controls: This product should be confined within closed equipment, in which case general (mechanical) room ventilation should be suitable. Special, local ventilation is needed at points where vapors are expected to be vented to the workplace air. Have eye baths and safety showers immediately available where eye contact and skin contact can occur. Work/Hygienic Practices: All employees who handle perch loroethylene should wash their hands before eating, smoking, or using the toilet facilities. Do NOT place food, coffee or other drinks in the area where dusting or splashing of solutions is possible. Exposure Guideline(s): Perchloroethylene: CAS Number 127-18-4, Exposure Limits (TWAs) in Air: ACGIH TLV: 25 ppm; OSHA PEL: 100 ppm; STEL: 100 ppm Personal Protection Personal Protection Equipment (PPE): Use only a MSHA/NIOSH-approved respirator to prevent overexposure if vapor levels may or do exceed the exposure limits. See SUPPLEMENTAL INFORMATION. Protective Clothing: Wear chemical goggles if there is the likelihood of contact with the eyes. Wear appropriate impervious gloves and protective clothing to prevent skin contact. Wear face shields and impervious aprons when splashing is likely. Remove contaminated clothing promptly and launder before reuse. Eye Protection: Employees should be provided with and required to use splash- proof safety goggles where there is any possibility of Perch loroethylene contacting the eyes. Section IX - Physical and Chemical Properties Physical State: Liquid pH: N/A Melting Point/Range: -190C (-2.2°F) Boiling Point/Range: 1210C (250°F) Appearance/Color/Odor: Clear, colorless liquid with an odor like chloroform or ether Solubility in Water: 0.015 g/100 g Vapor Pressure (mmHg): 18 @ 250C H2O (77°F) Specific Gravity (Water=l): 1.62 Molecular Weight: 165.85 Vapor Density (Air=1): 5.7 % Volatiles: 100 Evaporation Rate (BuAc=1): 0.33 (trichloroethylene = 1) How to detect this compound: In air, adsorption on charcoal, workup with CS2, analysis by gas chromatography. In water, inert gas purge followed by gas chromatography with halide specific detection (EPA Method 601) or gas chromatography plus mass spectrometry (EPA Method 624).
