The US American Health Hazard Evaluation (HHE) Program evaluated potential
exposures at a college's sculpture studios. Investigators recommended that
managers correct safety hazards in the studios and substitute a less toxic
plastics adhesive that does not contain methylene chloride. To reduce exposure
to welding fumes, it was recommended that adequate outdoor and replacement air
be supplied to the sculpture studios and local exhaust ventilation be installed
in the metalworking studio.
