HOW TO DETERMINE IF YOU ARE BEING * Post hazard and warning information in the work area. In EXPOSED addition, as part of an ongoing education and training The New Jersey Right to Know Act requires most employers effort, communicate all information on the health and to label chemicals in the workplace and requires public safety hazards of Iodine Pentafluoride to potentially employers to provide their employees with information and exposed workers. 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 1910.1020. * If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases.
