Here is what I found from NIOSH on Acetone. ACETONE PHYSICAL STATE & APPEARANCE Colorless liquid with characteristic odor PHYSICAL DANGERS Highly flammable - Flash point: -18C closed cup. Vapor/air mixtures are explosive. The vapor is heavier than air and may travel along the ground with distant ignition possible. CHEMICAL DANGERS The substance can form explosive peroxides on contact with strong oxidants such as acetic acid, nitric acid, hydrogen peroxide. Reacts with chloroform and bromoform under basic conditions, causing fire and explosion hazard. Attacks plastic. EXPOSURE Target Organs - Eyes, skin, respiratory system, central nervous system. Routes Of Exposure - The substance can be absorbed into the body by inhalation, ingestion and through skin and/or eye contact. Inhalation Risk - A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20C on dispersing however much faster. Effects Of Sort-Term Exposure - The vapor irritates the eyes and the respiratory tract. The substance may cause effects on the central nervous system, liver, kidneys and gastrointestinal tract. Symptoms include sore throat, cough, confusion, headache, dizziness, drowsiness, and unconsciousness. Effects Of Long-Term Or Repeated Exposure - Repeated or prolonged contact with skin may cause dry skin leading to dermatitis. Contact with the eyes can result in redness, pain, blurred vision and possible corneal damage. The substance may have effects on the blood and bone marrow. OCCUPATIONAL EXPOSURE LIMITS TLV: 750 ppm; 1780 mg/m3 (ACGIH 1993-1993). OSHA PEL: TWA 1000 ppm (2400 mg/m3) NIOSH REL: TWA 250 ppm (590 mg/m3) NIOSH IDLH: 2500 ppm LEL PERSONAL PROTECTION & SANATATION Skin: Prevent skin contact Eyes: Prevent eye contact Wash skin: When contaminated Remove: When wet (flammable) You can find a wealth of information about chemical hazards and emergency response on the World Wide Web. The following sites can help you determine what hazards are present in your workplace and how you can develop effective emergency response procedures: http://www.osha-slc.gov/SLTC/hazardoustoxicsubstances/index.html - OSHA's Hazardous & Toxic Substances website - Provides general information about hazardous and toxic substances, and then to provide access to more specific information sources. http://toxnet.nlm.nih.gov/ - National Institutes of Health - Contains links to a variety of databases. http://www.cdc.gov/niosh/ - National Institutes For Occupational Safety and Health - Databases of NIOSH publications and toxic effects of chemicals. http://scorecard.org - Environmental Defense Fund database focusing on Toxic Release Inventory information from companies and links to information on health effects of the chemicals subject to TRI Reporting. http://www.healtheffects.org http://tis.eh.doe/others/subject.html http://atsdr1.atsdr.cdc.gov:8080/toxfaq.html http://www.nsc.org/ehc/cameo.htm - National Safety Council Chemical Emergency Planning and Response Software http://www.crossroads.nsc.org - National Safety Council- Topics include Indoor Air Quality, MSDS databases,regulations and emergency management. http://chemfinder.camsoft.com/ - physical and chemical data for a large number of chemicals with links to databases on health effects. http://response.restoration.noaa.gov/chemaids/react.html - chemical reactivity data for chemicals and mixtures of chemicals http://hazmat.dot.gov/psnsort.htm - DOT North American Emergency Response Guide http://www.atsdr.cdc.gov/hazdat.html - Agency for Toxic Substances and Disease Registry hazardous substance information Gary Jones Graphic Arts Technical Foundation 200 Deer Run Road Sewickley, PA 15143 412/741-6860 x608 - Phone 412/741-2311 - Fax
