“…(10)(11)(12)(13)(14)(15)(16)(17)(18) However, the installation of such tables is no trivial matter, as it generally requires significant renovation or new construction to provide the necessary ductwork and mechanical support systems, plus initial capital expenditures for the tables. In addition, these systems have traditionally been designed to operate at relatively high volumetric exhaust flow rates, conditions which may be unsustainable for larger facilities.…”

This report describes efforts over a more than a 15-year period to improve air quality and reduce exposures to formaldehyde during anatomical dissections at the Yale University School of Medicine, including first-year medical student gross anatomy classes. During this time, a number of steps were taken to improve general ventilation system efficiency and work practices in the original facility. Subsequently, during the design phase for a new research and teaching building, a new anatomical laboratory was planned to incorporate 42 individually ventilated dissection tables. The tables were customized from a commercially available design to operate at lower volumetric airflow rates while still providing a high degree of formaldehyde containment. Air monitoring performed throughout this time period showed progressive reductions in formaldehyde exposure as ventilation modifications were made. However, significant reductions only occurred after the installation of the ventilated tables. Personal and area exposure monitoring during thoracic and abdominal dissections now show a five- to tenfold reduction in formaldehyde exposure compared to previous operations, with exposures consistently below 0.1 ppm.

“…Various approaches have been suggested to control exposure, including good work practices, alternative embalming agents/formulations, personal protective equipment, dilution ventilation, and local exhaust. Of all the proposed methods, only local exhaust ventilation combined with good work practices can show promise in controlling formaldehyde exposure in the laboratory for normal functioning (Adamović et al, 2021;Demer and Notary 1999).…”

Formaldehyde, which is exposure in the workplace, is very dangerous for health, especially for students, staff and lecturers in the anatomy laboratory room. Cadaver tables with local exhaust ventilation (LEV) in previous studies were used to reduce formaldehyde levels in the anatomy room. This study aimed to determine the effectiveness of a cadaver table with local exhaust ventilation to reduce formaldehyde exposure. Using a pre-post study, this study showed that a cadaver table with local exhaust ventilation can reduce formaldehyde exposure significantly (p<0.001) with a confidence interval of 2.715–2.186. The percentage reduction in formaldehyde levels at each measurement point was 31% - 89% (min-max). This showed that the cadaver table with LEV was effective in reducing formaldehyde levels.
