# Formaldehyde containment efficiency with a next-generation grossing station promising safer use in anatomical pathology practice

## TL;DR

A new grossing station for pathology labs was tested and found to safely contain formaldehyde, meeting international safety standards.

## Contribution

The study introduces a standard procedure for testing containment efficacy of next-generation grossing stations.

## Key findings

- The DFB900 grossing station achieved a protection factor of 105, complying with EU and NIOSH standards.
- The potassium iodide and tracer-gas tests confirmed its formaldehyde containment efficiency.
- The station's design supports safer and more efficient workflow in pathology labs.

## Abstract

Healthcare needs to re-evaluate its resources and make the processes more efficient. The pathologist's workspace is often narrow and limits access to grossing information mid-procedure. An ergonomic, open-front containment console – called grossing station – can improve this situation. Besides collecting airborne formaldehyde and chemical fumes, its cupboard with adjustable vertical protective screen simplifies the workflow with a customisable open work surface that allows image acquisition and includes voice recognition and waste dispensers. However, its containment efficiency and compliance with international safety standards has not yet been investigated. The aim of our study was to address this lack of information and propose a standard procedure for testing containment efficacy of next-generation grossing stations. For this purpose we ran the potassium iodide test and a formaldehyde leak test with a new tracer-gas method on a new DFB900 grossing station model and established that its protection factor of 105 complied with the EU standards and the NIOSH safety limits. Future research should include a range of new grossing stations and a wide spectrum of harmful compounds that pose occupational health risk to their operators.
