NIOSH: The recommended airborne exposure limit is * Contact can cause severe skin burns. 0.1 ppm averaged over a 10-hour workshift and * Exposure to Carbon Tetrabromide can irritate the eyes 0.3 ppm, not to be exceeded during any 15- causing intense tearing and may cause permanent eye minute work period. damage. * Breathing Carbon Tetrabromide can irritate the nose, ACGIH: The recommended airborne exposure limit is throat and lungs causing coughing, wheezing and/or 0.1 ppm averaged over an 8-hour workshift and shortness of breath. 0.3 ppm as a STEL (short term exposure limit). * Carbon Tetrabromide may damage the liver and kidneys. WAYS OF REDUCING EXPOSURE * Where possible, enclose operations and use local exhaust IDENTIFICATION ventilation at the site of chemical release. If local exhaust Carbon Tetrabromide is a colorless powder or yellow- ventilation or enclosure is not used, respirators should be brown crystalline (sand-like) solid.

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 1910.1020. * If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases.
