Describe two different ways medical assistance might be provided by a construction company
What will be an ideal response?
Companies may provide medical assistance on site or rely on third party providers (e.g. fire departments, emergency medical agencies, ambulance services, etc.). Relying on third party providers is the most widely used approach, but even when this is the preferred method, first aid supplies should be readily available at the job site. In addition, designated employees and/or supervisors should be trained in first aid fundamentals.

Repeat Problem 9.53 for the following specifications:
Vz = 12 V rz = 11.5 ? Prated = 400 mW
At the knee of the curve:
Izk = 0.25 mA rzk = 700 ?
Problem 9.53
The Zener diode in the simple voltage regulator shown in Figure P9.53 is a 1N5231B. The source voltage is obtained from a DC power supply. It has DC and ripple components: vS = VS + vr where:
VS = 20 V |vr| = 250 mV
R = 220 ? |io|avg = 65 mA |vo|avg = 5.1 V
Vz = 5.1 V rz = 17 ? Prated = 0.5W
|iz| min = 10 mA
Determine the maximum rated current the diode can handle without exceeding its power limitation.
