1 Wipe away the first drop of blood with a piece of clean, dry cotton gauze. 2  Since newborns do not often bleed immediately, use gentle pressure to produce a rounded drop of blood. 3  Do not use excessive pressure because the blood may become diluted with tissue fluid. 4  Fill the required microtainer(s) as needed.
You'll likely see labels like THHN or THWN written on the wire. For example, THHN wire stands for thermoplastic high heat-resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture-resistant nylon coated wire. As you can see, these wires are built to take on many different conditions.
PVC compounds stabilized with this additive have been approved by Underwriters Laboratories for both THWN and THWN-2 applications. Compared with a lead-based THWN formulation on 14 AWG wire, RC 215P yielded significantly higher insulation resistance values after 26-week immersion in water at 432 F, Ferro reports. Cable types covered include RHH, RHW, RHW-2, THW, THW-2, THHN, THWN, THWN-2, XHHW and XHHW-2; and AC, MC, TC and SE.
