Analysis of laser-generated plume concentration during in vivo laser hair reduction procedures in a tertiary referral laser dermatology unit

Abstract

Air particulate concentrations for a typical day of laser hair reduction procedures in a tertiary referral laser dermatology unit were measured, while all standard operating procedures were followed. Concentrations above the World Health Organisation PM2.5 Air Quality Guidance level were detected even following current guidance on room ventilation and local exhaust ventilation. This suggests that further analysis into this hazard is required to assess the use of current engineering and personal protective equipment controls for operators
