Common Name: CHLORPYRIFOS CAS Number: 2921-88-2 DOT Number: NA 2783 -------------------------------------------------------------------------HAZARD SUMMARY * Chlorpyrifos can affect you when breathed in and by passing through your skin. * Exposure to Chlorpyrifos can cause organophosphate poisoning with headache, sweating, nausea and vomiting, diarrhea, loss of coordination, and even death. * Chlorpyrifos may damage the nervous system and liver.IDENTIFICATION Chlorpyrifos is a white crystalline (sugar or sand-like) substance that smells like natural gas. It is a pesticide often sprayed as a water solution.REASON FOR CITATION * Chlorpyrifos is on the Hazardous Substance List because it is cited by ACGIH, NIOSH, DOT, HHAG and EPA. * Definitions are provided on page 5.HOW TO DETERMINE IF YOU ARE BEING EXPOSED The New Jersey Right to Know Act requires most employers to label chemicals in the workplace and requires public employers to provide their employees with information and training concerning chemical hazards and controls. The federal OSHA Hazard Communication Standard, 1910.1200, requires private employers to provide similar training and information to their employees. * Exposure to hazardous substances should be routinely evaluated. This may include collecting personal and area air samples. You can obtain copies of sampling results from your employer. You have a legal right to this information under OSHA 1910.20. * If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases. Take this Fact Sheet with you. RTK Substance number: 0426 Date: February 1986 Revision: July 1996 -------------------------------------------------------------------------WORKPLACE EXPOSURE LIMITS NIOSH: The recommended airborne exposure limit is 0.2 mg/m 3 averaged over a 10-hour workshift and 0.6 mg/m 3 not to be exceeded during any 15-minute work period. ACGIH: The recommended airborne exposure limit is 0.2 mg/m 3 averaged over an 8-hour workshift. * The above exposure limits are for air levels only. When skin contact also occurs, you may be overexposed, even though air levels are less than the limits listed above.WAYS OF REDUCING EXPOSURE * Where possible, enclose operations and use local exhaust ventilation at the site of chemical release. If local exhaust ventilation or enclosure is not used, respirators should be worn. * If you apply Chlorpyrifos as a pesticide, you will need to use a respirator. (See Respiratory Protection) * Wear protective work clothing. * Wash thoroughly immediately after exposure to Chlorpyrifos and at the end of the workshift. * Post hazard and warning information in the work area. In addition, as part of an ongoing education and training effort, communicate all information on the health and safety hazards of Chlorpyrifos to potentially exposed workers.
