NIOSH: The recommended airborne exposure limit is * High exposure can cause headache, nausea, vomiting, 200 ppm averaged over a 10-hour workshift. dizziness, drowsiness and coma. * Prolonged or repeated skin contact can cause cracking and ACGIH: The recommended airborne exposure limit is drying of exposed areas. 200 ppm averaged over an 8-hour workshift. * sec-Butyl Acetate is a FLAMMABLE LIQUID and a DANGEROUS FIRE HAZARD. WAYS OF REDUCING EXPOSURE * Where possible, enclose operations and use local exhaust IDENTIFICATION ventilation at the site of chemical release.

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