Standardised environmental sampling. Lab technician demonstrating the standardised environmental sampling protocol. This sampling process is taking place within the confines of a negatively-pressurised ventilated hood, to prevent any airborne contaminants from entering the laboratory environment. The four glass panes to be sampled are all inside the hooded area reducing any further contamination, whilst the technician is using blue-coloured protective gloves, in order to protect her from the possibility of self-contamination. Here, she is using a standard sponge spatula to pick up microorganisms from the four glass specimen panes. Photographed at the Centers for Disease Control (CDC), USA.
