3. Larger size EKOPEKL sorbent particles should be investigated 

 to minimize the hazard to operators. 



4. Unless and until a satisfactory and an acceptable way is 

 found to reduce the dust level, all operators should be required 

 to wear breathing masks and protective glasses during use of 

 the sorbent distribution system. This is felt to be necessary 



to prevent possible damage to the breathing passages or the 

 lungs of the operators .
