Study of health implications effects in laser paint removal process based on PM1.0 and PM10.0 measurements

Health implications to the staff incharged was studied by measuring mass
density (N) of two types of particulate matter (PM1.0 and PM10.0) concentration
produced during laser paint removal process over three different types of car
coated substrate samples A, B and C. The lowest PM1.0 and PM10.0
concentrations detected for those substrate samples during 10 minute laser
irradiation were 0.693 mg/m3
and 1.586 mg/m3
, which was far exceed
compared to the recommendation suggested by World Health Organization
(WHO). However, laser paint removal techniques was considered safe
compared than chemical paint stripping technique if smooth air ventilation in
workplace was properly set-up and inhalation to PM1.0 and PM10.0 was greatly
prevented by using protective mask
