Oil-like residue on a wall of a former limestone quarry cavern in Ohio

Summary

[edit]
Description
English: Oil-like residue on a wall of a former limestone quarry cavern in Ohio, being used as a storage warehouse for painted and sculptural artwork.

GC-MS analysis resulted in a few small hydrocarbon peaks likely in the range of C20 and greater, and a few small peaks potentially indicating polycyclic hydrocarbons with molecular weights greater than 300 atomic mass units.

This photograph was taken during a Health Hazard Evaluation, a NIOSH program by which employees, union officials, or employers can request an evaluation of possible health hazards at their workplace at no cost to them.
