I would be Interested in your reaction. Is 5 MMPCF still considered good enough, or should ve go to remote-controlled equipment and air-line masks k e the nuclear industry uses? I've seen one article which implies that crocidolite may be the harmful variety rather than chrysotlle. Have you anything on comparative toxicology of various species of asbestos? Very truly yours, J. A. Kiddle JAR/jcb Enc;
