Hazardous lighting

The authors reviewed, through a case study and project cost estimates, the savings and benefits achieved for a 175,000-barrel/day refinery on the East Coast of the United States. The latter sections of this article examine a lighting upgrade enlisting the newly available restricted breathing technology. The savings of 48% for reproducing the same illuminance or 24% for producing even and adequate lighting will be illustrated by comparing the cost of this upgrade to estimates of upgrades that do not use restricted breathing. An estimate of a new installation saving 51% using restricted breathing will be compared to one that does not. The article with describe in detail how these estimates and savings were determined.
