Hazard Information Bulletin: Barnstead/Thermolyne Equipment |
The Dallas Regional Office (Region VI) has brought to our attention a
potential hazard associated with the use of pre-1984 Barnstead/Thermolyne
Laboratory precision heating and stirring apparatus (bench type ovens,
furnaces, hot plates, dri-bathes, incubators, and heat tapes). These units
are equipped with exposed heating coils, and are not intended for use in or
around flammable or combustible materials. The hazard was brought to the
Dallas Regional Office's attention by Barnstead/Thermolyne Corp.
In 1984, the Barnstead/Thermolyne Company offered to affix warning labels on
electrical laboratory equipment sold in the United States and Canada prior to
that date. This warning label was affixed to notify users whether this
equipment could be used in or around flammable or combustible laboratory
operations. Because some pre-1984 equipment may still be in service,
Barnstead/Thermolyne sent us the attached self-explanatory letter for
information and use.
According to Barnstead/Thermolyne, all non-explosion proof units
manufactured after 1984 have carried warning labels against the presence of
flammable materials. As you know no electrical laboratory apparatus,
regardless of brand, shall be used in the presence of flammable or
combustible materials unless the apparatus has the appropriate approval from
a nationally recognized testing laboratory.
Please distribute this bulletin to Area Offices, State Plan States, and
Consultation Project Officers.
