98Smoker's home destroyed and neighbor injured
- Kalispell MO, 15 July 2004 A home on Kalispell's
west side was extensively damaged Wednesday
morning by a fire that was probably started by a
cigarette and was accelerated by oxygen from
medical oxygen tanks. A neighbor, who was trying
to help was knocked down by the explosion of one
oxygen tank, which also caused temporary hearing
loss for a police officer. - A report by F. Ray Ruffatto of the fire
department's prevention division said that while
the exact cause of the fire is still
undetermined, "initial investigation indicates
the fire may be the result of carelessly
discarded smoking materials."
99Smoker dies in house fire
- Hudson MA 21 July 2004
- The victim of yestrerday's fire died after
suffering second- and third-degree burns from a
devastating blaze at her Manning Street home
Sunday. - The resident was a smoker, according to State
Fire Marshal Stephen Coan, and he said the
combination of cigarettes and the multiple oxygen
tanks in the home either caused or exacerbated
the fire. - She was in critical condition after being pulled
from the house by a neighbor and then died
yesterday at UMass Memorial Medical Center,
University Campus in Worcester. - The combination of oxygen tanks and cigarettes
have sparked fires that since 1997 have killed 16
people in the state and caused severe burns or
smoke inhalation in 20, said Coan.

- "Acetone, oil, and alcohol are appropriate
substances to use with clients who are using
oxygen." - "Avoid materials that generate static
electricity."

the portable tank on a consistent basis - I will keep my scented candles within 5 feet of
my oxygen tank - I will not sit in front of my wood-burning
fireplace with my oxygen on. - I will call the physician if I experience any
shortness of breath
