Chemical Used to Strip Bathtubs Linked to Worker Deaths: CDC

THURSDAY, Feb. 23 (HealthDay News) — A chemical used to strip
bathtubs has been associated with more than a dozen deaths of people
working as bathtub refinishers in the United States in the last 12 years,
according to a new report.

Methylene chloride is used in industrial processes but is also
available in over-the-counter paint- and finish-stripping products. It’s
previously been identified as a potential cause of death among furniture
strippers and factory workers, according to a news release from the U.S.
Centers for Disease Control and Prevention (CDC).

In 2010, the U.S. National Institute for Occupational Safety and
Health-funded Michigan Fatality Assessment and Control Evaluation program
investigated the death of a bathtub refinisher in the state who used a
methylene chloride-based paint-stripping product marketed for use in
aircraft maintenance. Investigators also identified two earlier, similar
deaths in Michigan.

The U.S. Occupational Safety and Health Administration also identified
10 other deaths of bathtub refinishers who used methylene chloride
stripping agents that had been investigated between 2000 and 2011 in nine
states.

All of the deaths occurred in residential bathrooms with inadequate
ventilation. The victims either did not use protective respiratory
equipment or the equipment they used did not protect against methylene
chloride vapor, according to the report in the Feb. 24 edition of the
Morbidity and Mortality Weekly Report, published by the CDC.

Victims ranged in age from 23 to 57 years, and 12 of the 13 were male,
the authors of the report noted.

“To use products containing methylene chloride safely, work areas must
be well-ventilated, and when levels of methylene chloride exceed
recommended exposure limits, workers must use protective equipment,” study
co-author Kenneth Rosenman, chief of the Division of Occupational and
Environmental Medicine in the College of Human Medicine, at Michigan State
University, said in a university news release. “In a small bathroom, it is
unlikely these products can be used safely,” he added.

Ten different products were associated with the deaths, with six
marketed for use in the aircraft industry and the others for use on wood,
metal, glass and masonry. Bathtub refinishing was not mentioned on any of
the product labels.

Methylene chloride concentration in the stripping products ranged from
60 percent to 100 percent.

“The extreme hazards of using products with this chemical in bathtub
refinishing need to be clearly communicated to employers, workers and the
general public,” Rosenman said. “Safer methods using alternative products
should be recommended.”
