Legal Notice
The Phosgene Safe Practice Guidelines Manual (Manual) was prepared by the American Chemistry Council's Phosgene Panel (Panel). The Manual is intended to provide general information to persons who manufacture, use, or handle phosgene. The Manual is not intended to be a "how-to" manual, nor is it a prescriptive guide. Individual companies may need to vary their approach with respect to particular practices described within the Manual based on specific factual circumstances, the practicality and effectiveness of particular actions, and/or economic and technological feasibility.
The Manual is not intended to be a substitute for in-depth training or specific requirements, nor is it intended to define or create legal rights or other obligations. All persons involved in manufacturing, using, or handling phosgene have an independent obligation to ascertain that their actions are in compliance with current federal, state, and local laws and regulations and should consult legal counsel concerning such matters.
Neither the American Chemistry Council, nor the individual member companies of the Phosgene Panel, nor any of their employees, subcontractors, consultants, or other assigns, makes any warranty or representation, either expressed or implied, with respect to the accuracy or completeness of the information contained in the Manual; nor do the American Chemistry Council or member companies assume any liability or responsibility for any use, or the results of such use, of any information, procedure, conclusion, opinion, product, or process disclosed in this Manual.
The Manual has been designed and distributed in a manner that accommodates periodic updates. Because the Manual may be updated periodically, contact the American Chemistry Council to obtain the most current version of the Manual. Should you have specific questions about information contained in the Manual, you may contact the American Chemistry Council or the identified Panel member companies for further information.
