Accessibility and Safety for Disabled Workers: Workplace Ergonomics
Accessibility for Disabled People in the Workplace
Workplaces, including doors, passageways, toilets, and workstations, should be designed for easy access and safe operation for disabled employees.
Essential Services and Resting Areas
- Potable water must be readily available.
- Sufficient changing rooms should be provided.
- Adequate numbers of showers, toilets, and washbasins with hot and cold water should be available.
- Rest rooms with tables and seating should be provided.
- Pregnant women should have access
Digital Fluoroscopy and Computed Tomography
Gain Reduction and Digital Fluoroscopy
Gain Reduction: (Inlet Diameter)2 / (Output Diameter)2
Further Conversion Factor: Light Output Intensity / Current Input RX. A larger gain implies a smaller image with increased brightness.
Digital Fluoroscopy
Involves removal or subtraction techniques.
- Interrogation Time (TI): The time required for the X-ray tube to be switched on and reach the selected level of kV and mA.
- Extinction Time (TE): The time required for the X-ray tube to be switched off. Digital fluoroscopy
