ToxStrategies consulting scientists have extensive industry and regulatory experience and can assist clients in complying with the United Nation’s Globally Harmonized System (GHS). In particular, we have wide-ranging experience with GHS as it is incorporated into the Occupational Safety and Health Administration’s 2012 revised Hazard Communication Standard (OSHA HazCom, or HCS) and the EU’s Registration, Evaluation, Authorization and Restriction of Chemical Substances (REACH) and Classification, Labeling and Packaging of Substances and Mixtures (CLP) regulations. This background includes toxicological study evaluation, hazard and risk assessment, data documentation and entry, and generation of toxicological summaries and Chemical Safety Reports. ToxStrategies’ consulting services can be tailored to provide a level of support that fits your company’s needs, from managing the entire scientific program to required data entry.
