What it is Filled
Force applied perpendicular to a surface per unit area, measured in pascals (N/m2); includes atmospheric, hydrostatic, gas and blood pressure, expressed as absolute or gauge pressure.
Why it exists Filled
Let an agent handle pressure by kind, units, measurement and safety, and route blood pressure questions to health guidance without diagnosis.
Distinguishing features Filled
- Force per unit area
- Scalar quantity
- Many units in use
- Relevant to safety
What robots and AI may and may not do Filled
Must not
- Report a gauge reading as absolute pressure, or the reverse, in a safety calculation.
- Raise a system above its rated pressure or defeat a relief device.
- Interpret a person's blood pressure reading as a diagnosis or change their medication.
- Suppress or smooth away a pressure alarm on a vessel or pipeline.
Only with a human decision
- Any change to the set point of a relief or safety device.
- Taking a pressurised system out of or back into service.
May
- Convert pressure units and state whether a figure is gauge or absolute.
- Read instrument and system pressure data it is authorized to access and report it.
- Flag a reading outside the stated safe range to the operator.
Moral aspects Filled
- Pressure vessel and pipeline failures kill people nearby.
- Misread blood pressure leads to wrong treatment decisions.
Who is affected
- Workers near pressurised equipment
- People living near installations
- Patients
Owners Filled
Steward
The operator of the pressurised system; for units, the international system of units defines the pascal.
