Potential of Asbestos Exposure From Storeroom Materials Plant Stores, Building 307-1 & North Charleston Storage
Building 8-505 South Charleston Plant Project No. 514-H-307-8-505-76_________________________________________
Jim, as you requested, we have made an initial determina tion of the potential of asbestos exposure at the two storeroom locations in the South Charleston Plant including North Charleston Storage, Building 8-505.
In surveying these areas with Mr. Arlie Lynch and Mr. Ray Harris, the storage areas were found clean and orderly with minimal deposits of dust from asbestos material. However, as Mr. H. H. Frazier from the Institute Plant pointed out in his report (attached) of an asbestos dust exposure study, it is recommended to isolate the materials containing asbestos fibers. This could be accomplished by storing all materials in plastic containers including the asbestos cloth on rolls. In this way the employee dispensing the material would be freeing the bulk of the asbestos dust inside of the plastic container.
According to Arlie the majority of the asbestos containing material is dispensed as stored and eliminate the untangling and preparation of small quantities of the material.
Based upon these observations, compliance with the program of isolating the asbestos containing material, and the air sampling results from Mr. Frazier, we feel that the potential for exposures of the stores employees' to asbestos dust exceeding
2 fiber/cc greater than 5 fd in length will not be exceeded.
An Environmental Health Data Sheet is attached for Asbestos.

Wear protective clothing. If contacted, wash affected skin areas with water. Maintain and laundry protective clothing.

Wear respiratory protection and use. with adequate ventilation. If exposed, wash eyes with water. Report to the Medical Department.

The potential ffir excessive oiuployee exposure in asbestos fibers In appari'nt ul the different storage bln local Ions and especially al l lie asheslm: rope dispensing bin. Each time rope or gaskets are removed from l lie storage bin, .inhesion fibers are released and are plainly visible. liberated fibers are deposited and/or are accumu lated on the floor with the potential of becoming, airborne due to sweeping or generated air currents.
Although the potential for excessive exposure appears to he serious, the results obtained during our sampling evaluation arc weLl within Lhe limits of the new ThV of two fibers greater than five micrometers per milliliter of air. One reasonable explana tion for the lower than expected values is that fibers being, liberated are large and of sufficient density that they do not easily become airborne. Asbestos must, nevertheless be controlled wherever possible.
