Risk

Control of risk is a pervasive issue in engineered processes. All Engineer-it strategies contibute to minimisig the risk of unsatisfactory outcomes.

A common defininition of risk is: the combination of the likelihood of occurrence and the consequences of a hazard (i.e. a negative event i.e. a hazard.

A process for controlling risk is:

First, identify the hazard; then in order of preference:

1. Take action to eliminate it
2. Seek to reduce the likelihood of the event
3. Seek to reduce the consequences should the event occur.

What if analys people say o ideay what mi - the hazard. The hazard might be eliminated by having only robots working on the scaffold.
To reduce the likelihood a waist high barrier can be provided
To reduce the consequences of a fall the operators may be attached by a safety rope.on hteht go wrong in a system

Formal approaches to risk control inclued

Use of a risk register where the hazards are identified, quantified and mitigated

Hazard and operability analysis (HAZOP) - typically used for the design and operation of chemical plant
