The three principles that describe how the economy as a whole works are: (1) a country's standard of living depends on its ability to produce goods and services; (2) prices rise when the government prints too much money; and (3) society faces a short-run tradeoff between inflation and unemployment.
The ways that are required to prevent fire include:
- Accessible equipment.
- Proper disposal.
- Regular maintenance.

It should be noted that it's essential to make all fire protection equipment easily accessible. There should also be proper disposal of hazardous wastes.
