Sobel DATE: May 31, Director of Environmental & Process Technology SUBJECT: INDUSTRIAL HYGIENE - ASBESTOS 1972 1. Please note attached copies of newly issued Corporate Engineering standards for application of asbestos fiber insulation to high-temperature equipment. 2. In my opinion, some reference to OSHA standards and the need for monitoring and personnel pro tection should be included in the standard. The attendant costs should be part of engineering estimate. 3- Reference to the hazard and its control in our Corporate standard would constitute evidence that our engineers are fully cognizant of the asbestos problem.

ADDENDUMS Exceptions, deviations, deletions or addi tions to this Standard to define any specific requirements shall be as contained in an addendtun(s) to this Standard. When so specified the requirements of the addendum(s) shall take precedence. .4 INSULATION THICKNESS The thickness of applied insulation shall be as specified in the Application Schedule in an addendum or as contained in any other appli cable document. The Insulating material shall be appliec the specified thickness using blowers and spr. noirles that blend the asbestos fiber with wa- to form a continuous, monolithic insulation, applied insulation shall be consolidated to the specified thickness within 30 minutes after sc tag, to a smooth surface free from visible de fects, by pressing or light tamping with a troor a board. Insulation shall not be applied du inclement weather or when the temperature ci surfaces to be insulated or that of the surrou-. area is below 32F. When the applied and tamped insulation over 2" but not over 4" thick or when applied tank* and vessels over 4 ft. diameter, mecr.asupport in the form of attachment pins (Para. shall be need, spaced as follows: Vertical Surfaces - IS" Tank fc Vessel Tops - 24'" Flat or Conical Bottom* - 12" Squares of hardware cloth, 4" x 4" shall be Impaled on Che pins and into the insulation be:': it has been pressed and tamped and pin speed clip* installed over the cloth.
