Safety from exposure to  Infectious Agents

Smallpox

 MEDICINE: referring to organs or tissues from biological origin, or genetic therapy products, virus; levels of lab containment protocols BSL-1, 2, 3, 4 in rising order of danger

 CHEMISTRY: i.e., nitrates in water, PCB levels affecting fertility

 ECOLOGY: referring to imported life forms not indigenous to the region (Reggie the alligator)  AGRICULTURE: reducing the risk of alien viral or transgenic genes, or prions such as BSE/"MadCow“; reducing the risk of food bacterial contamination

 EXOBIOLOGY: i.e., NASA's policy for containing alien microbes that may exist on space samples - sometimes called " biosafety level 5"

 Charles Baldwin at National Cancer Institute at NIH.

 Symbol to be

“memorable but meaningless” so it could be learned.  Blaze orange – most visible under harsh conditions

(1) laboratory practices needed to handle serious human and animal pathogens,

(2) possibility of creation of 'hybrid organisms' with biological activities of an unpredictable nature, and

(3) the escape of 'hybrid organisms' from the laboratory with unpredictable consequences.

(i) certain experiments should be deferred,

(ii) most of the work on recombinant DNA could proceed with appropriate safety measures,

(iii) potential risks were assigned to different types of experiments, and

(iv) such safe bacteria and plasmids that could not survive in the environment if they escaped from the laboratory should be developed.

 The first NIH guidelines were prepared in 1975; they were

more strict than the recommendations of the Asilomar conference.

 The guidelines were revised after two years; and were made much less restrictive. By 1981, most cloning experiments in E. coli K-12, certain strains of Bacillus subtilis and Saccharomyces cerevisiae were considered exempt from other requirements of NIH guidelines.

 Eventually, complete exemption was granted for most recombinant DNA research. A major revision of the guidelines was effected in 1982; containment levels were lowered, and experiments that were previously prohibited, were changed to category requiring review and approval by NIH
