4. As a scientist with a deep concern for the need to protect the experi- 
mentalist and the public at large from the potential hazards of scientific 
research, I applaud the revised guidelines as a document that will provide 
excellent protections while not severely impeding research. Because of the 
safeguards built into the guidelines and because of the heightened awareness 
of the scientists engaged in recombinant DNA research, I now consider my P3 
facility to be the safest room in Building 37, both for those who work in- 
side it and for those who do not.
