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

Exposures in the community, except possibly in cases of fires or spills, are usually much lower than those Industrial Hygiene Information found in the workplace.
