We must also _ try to show what degrees of severity of exposure occurred in these opera tions. We must at least derive the implication that TWA exposure levels were at least 50 ppm and possibly higher. Since we do not know when a permanent standard will issue, we must plan for the worst and handle this like a "crash1!. prograacr> Please try to complete this form and return it to SPI offices bY'May 15, 1974 at the latest.
