Arson, the second leading cause of residential fire-associated deaths in the United States, accounts for approximately 700 deaths annually, destroys homes, and destabilizes neighborhoods. In Detroit, Michigan (1990 population: 1,027,974), arson accounted for nearly half (46.3%) of all fire-related deaths since 1984. During the late 1970s, pre-Halloween pranks traditionally associated in some parts of the United States with the night of October 30 turned destructive in Detroit, with hundreds of fires set throughout the city. By 1984, October 30 became known as "Devil's Night" and had evolved to 3 consecutive nights of arson on October 29-31; in that year, a record 810 fires were reported. In 1985, Detroit began a citywide intervention campaign against arson and vandalism during the 3-day Halloween period using data from an ongoing fire surveillance system maintained by the Detroit Fire Department (DFD) to target areas at high risk for arson. This report describes the intervention implemented by the city of Detroit from 1985 through 1996 and the impact of the intervention in preventing Halloween arson; approximately 34,000 volunteers participated in 1996, and the number of fires during this 3-day period decreased to the average number of fires for any other 3-day period during the remainder of the year.

CO2 laser safety considerations in facial skin resurfacing.

Carbon dioxide lasers have been used increasingly in the field of aesthetic plastic surgery, specifically for facial resurfacing procedures. As many plastic surgeons are now venturing into the arena of laser surgery for the first time, it is paramount to understand basic laser safety principles to protect our patients, the operating room personnel, and the laser surgeon. This article reviews basic laser principles and practices and delineates the safety requirements needed to perform laser resurfacing using the CO2 laser system. We subjected several common objects present in the operative field during resurfacing procedures to multiple passes of both the Coherent 5000 C laser and the Laser Industries (Sharplan) model 150XJ laser Silktouch to assess flammability and margins of safety. We tested endotracheal tubes, wet and dry towels, wet and dry gauze sponges, cottonoids, eye protectors, and ophthalmic ointments. Neither flame nor burn was incited in the moistened preparations. The dry objects tested produced flame. The plastic corneal protectors began to melt by the third pass and produced significant heat. Lastly, both the Lacrilube and Bacitracin ophthalmic ointments began to vaporize after three laser passes. On the basis of our findings in this study, we recommend guidelines for prudent and safe CO2 laser usage in facial skin resurfacing.
