INTRODUCTION
The Troxler NTO Asphalt Content Ignition Oven is designed to be
safe for the user. The system uses modern, refractory ceramic fiber
(RCF) materials to provide highly efficient insulation of the heated
chambers. This material is completely enclosed, and should present
no health risk to the operator during normal use in accordance with
this manual. RCF can present a potential health hazard if the fibers
become airborne and thus become respirable. Since, under normal
operating conditions, the design of the oven completely encloses
these materials, fibers should not become airborne during normal
use. Therefore, no special precautions are necessary when using the
oven to perform asphalt content analysis.
Special precautions should be taken during maintenance operations
or other activities that involve removal of the system sheet-metal
covers.
These maintenance operations should be performed only
by authorized, experienced maintenance personnel . They include
removal of the rear or top panels for troubleshooting, cleaning, or
making repairs.
During the performance of such maintenance operations, observe
the precautions set forth in the Material Safety Data Sheets
(MSDSs) enclosed with the product. Wear respirators approved by
the National Institute for Occupational Safety and Health (NIOSH)
to prevent possible inhalation of airborne ceramic fibers. Wear
gloves and long sleeve clothing to prevent irritation of the skin.
Wear safety goggles to prevent irritation of the eyes. Unplug the
oven from its power source before performing any maintenance
operations.
All maintenance operations should be performed with special effort
to minimize generating airborne fiber dust. Do not use compressed
air to clean and do not rub or wipe ceramic fiber surfaces. Although
no periodic cleaning of ceramic fiber surfaces is required, it is best
to use a vacuum cleaner equipped with a high-efficiency particulate
air (HEPA) filter system to remove any debris from the surfaces of
the ceramic fiber, if desired. This applies to the outside or inside of
the primary, heated oven chamber.
