“…The TDC from manual dry sanding, putty sanding, undercoat sanding, resurfacing sanding was also much more than the OELs, because dust control is difficult. Unssen et al (2008) and Lazovich et al (2002) found that there should be more focus on improving exhaust ventilation, professional cleaning methods, and worker training to reduce inhalable wood dust concentration.…”

To provide an in-depth understanding of preventing occupational diseases and improving working conditions, characteristics of inhalable dust were studied. The results showed that total dust concentration (TDC) from mechanical sanding, portable planning and sanding, putty sanding, and painting sanding with inadequate exhaust ventilation were higher than occupational exposure limits (OELs). The more the furniture material was sanded and the worse the dust exhaust apparatus, the higher the TDC was. The TDC from portable planer sanding and dry sanding and putty sanding was in the range from 8.4 mg/m 3 to 8.7 mg/m 3 and from 5.3 mg/m 3 to 8.4 mg/m 3 , respectively. The TDC from mechanical sanding and painting sanding was in the range from 4.4 to 6.4 mg/m 3 and from 3.4 mg/m 3 to 4.9 mg/m 3 , respectively. More than 90% suspended particulate matter in their TDC had a PM10 in all aforementioned results. The sanding procedure produced 6.7% to 8.2% free silica in the total particulate matter, in addition to wood dust, putty dust, or painting dust. Heavy metals in dust from putty sanding and painting exceeding the OELs were lead (Pb; > 0.3 mg/m 3 ) and cadmium (Cd; > 0.01 mg/m 3 ). There was a large amount of granular grinding material, cluster putty, planar painting dust, and a small amount fibroid wood dust in the dust from putty sanding and painting sanding.

Study characterized and analyzed form factor, elementary composition and particle size of wood dust, in order to understand its harmful health effects on carpenters in Quindío (Colombia). Once particle characteristics (size distributions, aerodynamic equivalent diameter (D a ), elemental composition and shape factors) were analyzed, particles were then characterized via scanning electron microscopy (SEM) in conjunction with energy dispersive X-ray analysis (EDXRA). SEM analysis of particulate matter showed: 1) cone-shaped particle ranged from 2.09 to 48.79 µm D a ; 2) rectangular prism-shaped particle from 2.47 to 72.9 µm D a ; 3) cylindrically-shaped particle from 2.5 to 48.79 µm D a ; and 4) spherically-shaped particle from 2.61 to 51.93 µm D a . EDXRA reveals presence of chemical elements from paints and varnishes such as Ca, K, Na and Cr. SEM/EDXRA contributes in a significant manner to the morphological characterization of wood dust. It is obvious that the type of particles sampled is a complex function of shapes and sizes of particles. Thus, it is important to investigate the influence of particles characteristics, morphology, shapes and D a that may affect the health of carpenters in Quindío.
