UN 1008: BORON TRIFLUORIDE

UN 1008 (BORON TRIFLUORIDE) belongs to ADR class 2 (Gases). Hazard identification number: 268. Tunnel restriction code: C/D.

Class
2Gases
Classification code
2TC
Warning labels
2.3, 8
Hazard identification number (Kemler)The first digit is the main hazard (2 gas, 3 flammable liquid, 4 flammable solid, 5 oxidising, 6 toxic, 8 corrosive, 9 miscellaneous), the next digits are additional hazards, a repeated digit (e.g. 33) means an intensified hazard, an X before the number means a dangerous reaction with water.
268
Tunnel restriction code
C/D: Code with a slash: the restriction depends on the way of carriage (in a tank or otherwise). See table 8.6.4 of ADR. Tunnel categories in the code: C, D.
Transport categoryThe transport category (0 to 4) sets the multiplier: according to ADR Check, category 1: multiplier 50, category 2: multiplier 3, category 3: multiplier 1, category 4: multiplier 0 (no limit), and category 0 means the exemption does not apply. Points are the net quantity (kg or L) times the multiplier.
1
Multiplier for the 1000-point limitPoints are the net quantity (kg or L) times the multiplier; a load total not exceeding 1000 points falls within the ADR 1.1.3.6 exemption.
50
Limited quantity (LQ)The largest quantity per inner packaging for which carriage can use the limited-quantity rules.
0
Excepted quantity (EQ)A code indicating the limits for excepted quantities; its content is given in the text of ADR.
E0
Packing instructionsPacking instruction codes (e.g. P, IBC, R) indicate which packagings are permitted.
P200
Mixed packingCodes (MP) say how this substance may be packed together with others in one outer packaging.
MP9
Loading, unloading and handlingThe codes indicate provisions on carriage, loading and unloading.
CV9, CV10, CV36
Operation of the vehicleCodes (e.g. S2, S20) indicate additional operating provisions for carriage.
S14
Environmental hazard
yes

The content of the packing codes and the carriage provisions is in ADR, chapters 4.1 and 7.

Special provisions

  • 373: Neutron radiation detectors containing non-pressurized boron trifluoride gas may be carried under this entry provided that the following conditions are met:
    Show the full provision
    (a) Each radiation detector shall meet the following conditions. (i) The pressure in each detector shall not exceed 105 kPa absolute at 20 °C; (ii) The amount of gas shall not exceed 13 g per detector; (iii) Each detector shall be manufactured under a registered quality assurance programme; NOTE: ISO 9001 may be used for this purpose. (iv) Each neutron radiation detector shall be of welded metal construction with brazed metal to ceramic feed through assemblies. These detectors shall have a minimum burst pressure of 1800 kPa as demonstrated by design type qualification testing; and (v) Each detector shall be tested to a 1 x 10 EXP(-10) cm³/s leaktightness standard before filling. (b) Radiation detectors carried as individual components shall be carried as follows: (i) Detectors shall be packed in a sealed intermediate plastics liner with sufficient absorbent or adsorbent material to absorb or adsorb the entire gas contents; (ii) They shall be packed in strong outer packaging. The completed package shall be capable of withstanding a 1.8 m drop test without leakage of gas contents from detectors; (iii) The total amount of gas from all detectors per outer packaging shall not exceed 52 g. (c) Completed neutron radiation detection systems containing detectors meeting the conditions of paragraph (a) shall be carried as follows: (i) The detectors shall be contained in a strong sealed outer casing; (ii) The casing shall contain sufficient absorbent or adsorbent material to absorb or adsorb the entire gas contents; (iii) The completed systems shall be packed in strong outer packagings capable of withstanding a 1.8 m drop test without leakage unless a system's outer casing affords equivalent protection. Packing instruction P200 of 4.1.4.1 is not applicable. The transport document shall include the following statement "Transport in accordance with special provision 373". Neutron radiation detectors containing not more than 1 g of boron trifluoride, including those with solder glass joints, are not subject to ADR provided they meet the requirements in paragraph (a) and are packed in accordance with paragraph (b). Radiation detection systems containing such detectors are not subject to ADR provided they are packed in accordance with paragraph (c).
