Safety Information & Guidelines
Boron Trifluoride Gas (BF3)
Boron Trifluoride
Gas (BF3)
oron Trifluoride
Gas (BF3)
The ion chamber detector may be filled with Helium-3 (He3) or Boron
Trifluoride (BF3) gas. If the detector is filled with BF3, it is critical to read
this section carefully. The type of gas is identified on the instrument
housing.
Warning BF3 is a pungent smelling, toxic, corrosive gas with a suffocating
odor. Inhalation will cause moderate to severe irritation or burns to the
respiratory system. Appropriate precautions must be taken to ensure the
safety of personnel. ▲
Warning If exposed to extremely high temperatures, BF3 can decompose
and generate irritating vapors and toxic gases. ▲
Warning Health risks vary depending on duration and level of exposure.
Exposure to 50 ppm, for example, may be fatal if inhaled for 30–60
minutes (due to massive inflammation and congestion of the lungs).
Inhalation of lower concentrations of BF3 can lead to nose and throat
irritation. Respiratory equipment and other personal protection equipment
must be used. ▲
BF3 is a colorless, fuming, pungent smelling gas. It is heavier than air and
fumes strongly in moist air, producing a dense, white cloud of fluoroboric
acid mist. The odor and dense, white appearance of this gas, upon release,
are distinctive warning properties associated with it.
Warning Fluoroboric acid mist can burn the skin or eyes. Burns may not
be immediately painful or visible. Depending on the exposure, effects can
be immediate or delayed. Skin contact can lead to pain, redness, and burns.
Eye contact may result in blindness. Personal protection equipment must
be used. ▲

troubleshooting, or repairing the instrument:
1. Use an antistatic bag. Most instrument subassemblies are shipped in a
special antistatic bag. When not installed, keep the assembly in the bag
as often as possible.
2. Remove ESD sensitive subassemblies only under the following
conditions:
a. When at a designated static-free workstation or when the bag is
grounded at a field site.
b. After the conductive area of the container has been neutralized.
c. After making firm contact with an antistatic mat and / or firmly
gripping a grounded individual.
3. Personnel handling ESD sensitive devices should be neutralized to a
static-free workstation by means of a grounding wrist strap that is
connected to the station or to a good grounding point at the field site.
4. Do not allow clothing to make contact with ESD sensitive devices.

installing the equipment.
Installation
Considerations
This section details the recommended installation procedures for standard
applications. If these procedures do not adequately address your particular
application, contact Thermo Fisher for recommendations that are more
specific. In all cases, radiation safety is a principal concern in the design and
manufacture of the system. When properly installed, the system presents no
hazards to personnel.
The neutron source is surrounded by an air space. The source housing is
shipped with the source shutter locked and in the OFF position. This lock
must remain in place until installation is complete and the equipment is
ready for start-up and calibration.
The system may only be used in those hazardous locations identified on the
product nameplates.
The system consists of four components:
●1400S transmitter: stainless steel (NEMA 4X)
