Evidence

A 2025 NIOSH evaluation of a school ceramics and visual-arts studio found no respirable dust, respirable crystalline silica, or respirable metals in collected air samples, but found metals on all tested surfaces and insufficient ventilation; NIOSH recommended improved cleaning and hand hygiene.

We found no respirable dust, respirable crystalline silica, or respirable metals in the samples.

The original NIOSH ceramics-studio report found metals on all tested surfaces and judged the studio ventilation insufficient, while recommending improved cleaning and cleanup procedures and ventilation assessment.

Metals were present on all surfaces tested. Respirable dust, respirable crystalline silica, and respirable metals were not present in any of the air samples collected. The art studio space was not set up to meet the needs of its occupants. Improve housekeeping and clean-up procedures. Evaluate the art classroom ventilation system.
