CARSON CITY — This week’s observance of National Fire Prevention Week in Nevada will conclude Saturday as the names of five fire firefighters who died in the line of duty are added to the Nevada Firefighters Memorial in Carson City.

Uniformed members from fire departments throughout Nevada will gather to pay tribute to their fallen comrades at the 10 a.m. ceremony in Carson City’s Mills Park. The ceremony is always held on the last Saturday of National Fire Prevention Week, and is open to the public.

Henderson Firefighter Jeff Mann, 57, and Clark County Fire Captain Gregory Malcolm Redmond, 48, both lost their lives to work-related cancer.

Cancer is considered a line of duty death because firefighters are exposed to the numerous chemicals and smoke that are present at every fire. Studies have shown that the cancer rate among firefighters is three times higher than the average population.

Mann was diagnosed Feb. 3 with melanoma cancer that had already spread. His physician documented the cancer as being caused by a 20-year firefighting career of exposure to carcinogens. Mann died on Feb. 27, a few months before his retirement.

Redmond died on Oct. 3, 1994, of colon cancer that physicians also attributed to exposure to carcinogens during his 20 years of service. Redmond underwent treatment, including two surgeries, and was still employed by the Clark County Fire Department when he died.

Others to be honored include a group of air tanker crewmen who died on Sept. 1, 2008 when their air tanker crashed shortly after takeoff from the Stead Airport on their way to a fire in Calaveras County, Calif.

Air tanker pilot Calvin Gene Wahlstrom, 61, of Huntsville, Utah; co-pilot Gregory Gonsioroski, 41, of Baker, Mont.; and 25-year old flight mechanic Zachary Jake VanderGriend of Missoula, Mont. all died in the crash.
