We as a company do not make any specific handling recommendations. There are, however, two publications which pertain to this matter. They are: Federal Register, October 9, 1975 - OSHA Regulations Federal Register, October 14, 1975 - EPA Regulations We suggest you refer customers seeking such information to these publications. -Gopies are-attached. ) R.

Pabco technical bulletin Pabco high temperature insulating systems 1 FREE SILICA TOXICITY PTB-48-3 8/78 Free silica toxicity is an old problem in industry. Inhalation of free (biologically active, crystalline) silica can lead to silicosis, a fibrotic condition of the lung tissue which reduces vital capacity, and makes the victim more susceptible to such diseases as pneumonia and tuberculosis. Various health studies have shown that the body can tolerate a certain amount of dust so long as it is not biologically active. The Airerican Council of Government and Industrial Hygienists (ACGIH) has set down guidelines for the amounts of various dusts that can be tolerated, the most inoccuous of which is designated as "nuisance dust". "Nuisance" dusts are defined as particulate materials containing no more than 1% free silica. The dust frcm Pabco Super Caltarp is by the above definition a "nuisance dust", and thus a minuted. hazard to workers. By test, our product contains less than 0.2% free silica. In Decenter, 1974, NIOSH published a reccnmended standard for "Occupational Exposure to Crystalline Silica". If adopted, this regu lation would require: 1. Manufacturers of all products such as Calsil to label pro ducts containing more than 5% free silica as hazardous materials. 2. Manufacturers aid users of such "hazardous" products would be required to conduct periodic physical exams and keep detailed health records of all errployees who came into con tact with such "hazardous" free-silica products. 3. Manufacturers and users to control free silica dust exposure to comply with standards or, when dust limits cannot be met, provide respirators for every worker exposed. 4. Manufacturers and users to conduct dust surveys -- both per sonal and workplace -- to demonstrate compliance with regu lations.

To repeat -- Pabco would not be affected by such regulations since we manufacture our Calsil frcm raw materials that contain almost no free silica. LAM 025812 ABS-016950
