Puerto Rican The attached data on VCM during loading of the S.S. Puerto Rican shows some high levels. I think we should talk to W. Hanmond and see what action and advice we should provide to operators of the ship. Zeb G. Bell, Jr. ZGB:mal Attachment FORM 503-A REV. 6-1-70 !

Lota: Although the CYA is calibrated for VC'*, any organic vapor present in the area will register. However, it is presured that organic vapors present in most of the areas monitored are -VCR.

Again the high reading found on #6 Dog house was reported to the first mate. The area was checked but the leak was still present. Finally at 07:15 AM the problem was resolved. It was"caused by a leak in a sample tube. It was fixed. 2* Since the OVA is not specific for VCM, several monitors which are specific for VCM were placed in the following areas.
