4.4.3—Health and safety

4.4.3 Health and safety.

• accidents at work focusing on human errors (errors of omission, commission, sequencing and timing) and system errors in operator-machine systems (machine controls and displays).
• reducing accidents at work: token economy, including a study, e.g. Fox et al. (1987).
• monitoring accidents (exemplified by the following key study).
• Key study on the monitoring of accidents and risk events: Swat (1997).

This matters because —health and safety determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply —health and safety to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: —Health and safety is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
