OBJECTIVES
To
characterise the distribution of particle size and mass of glove powder
aerosol released from powdered and powder free non-sterile latex gloves
under controlled conditions.
METHODSGravimetric
sampling and aerodynamic particle size analysis were performed during
simulated use of gloves on a prosthetic hand in a chamber designed to
minimise background particle concentrations.
RESULTSAerosol was
detectable for both powdered and powder free gloves under both
aggressive and non-aggressive handling conditions. Most of the
particles detected had aerodynamic diameter less than 10 µm.
CONCLUSIONPowder free
gloves were not entirely free of powder aerosol. Particles from both
powdered and powder free gloves are sufficiently fine to penetrate into
the thoracic region of the respiratory tract.
