†Reference source for the cost of medical care for fatal fire injuries does not distinguish between treatment locations.
‡Calculated as programme cost+medical costs.
§Calculated as programme cost+medical costs+lost productivity.
¶Calculated as (cost with programme − cost without programme)/(fire injuries with programme − fire injuries without programme).
**Calculated as (programme benefit/programme cost), can be interpreted as the return per $1 invested in the programme.
