The 1998 Donald E. Cummings Memorial Award Lecture. The industrial hygiene paradox, dilemmas, and a vision for the future.

How do we move from diatribe to dialogue? Since the Donald E. Cummings Award was first established in 1943, the profession of industrial hygiene has seen many changes. The traditional hazards Alice Hamilton addressed in her 1948 Cummings lecture have been controlled.

Comparison of metalworking fluid mist exposures from machining with different levels of machine enclosure.

This research investigated the efficacy of machine enclosures in reducing employee exposures to metalworking fluid mist. Four hundred fifty-five personal samples from automotive machining and grinding operations collected over six years were divided into three groups based on the type and extent of enclosure and local exhaust ventilation. The sample groups were (1) machining equipment with original equipment manufacturer (OEM) total enclosures and local exhaust ventilation, (2) machining equipment with partial or retrofit enclosures and local exhaust ventilation, and (3) machining equipment with little or no enclosure.
