# Measurement of Aerosol Particles from Vibrated Lab Coats

## TL;DR

This study shows that shaking lab coats releases more large particles into the air, which could affect clean environments like labs.

## Contribution

The study reveals how lab coat vibration affects aerosol particle distribution, particularly for larger particles.

## Key findings

- Vibrating lab coats increased particles larger than 5 μm while decreasing submicron particles.
- Old lab coats showed greater particle concentration variation compared to new ones or shirts.
- Suits did not significantly affect particle concentrations when vibrated.

## Abstract

A study was conducted to measure aerosol particles emitted from laboratory coats (lab coats) under vibration, comparing them with a suit and a shirt. This study focused on particles ranging from 0.3 μm to >10 μm. Experimental results showed that lab coat vibration increased particles >5 μm while reducing submicron particles. The lab coat (old and used) exhibited greater particle concentration variations under vibration compared to those using the new lab coat or the shirt. Contrastingly, the suit under vibration did not significantly affect particle concentrations. These findings highlight the impact of lab coat vibration on aerosol particle concentrations in the surrounding air, which is important for work environments.
