2.2.52.1.13

Water may only be used for the desensitization of organic peroxides which are listed in 2.2.52.4 or in the competent authority decision according to 2.2.52.1.8 as being "with water" or "as a stable dispersion in water". Samples of organic peroxides or formulations of organic peroxides not listed in 2.2.52.4 may also be desensitized with water provided the requirements of 2.2.52.1.9 are met.

2.2.52.1.14

Organic and inorganic solids may be used for desensitization of organic peroxides provided that they are compatible. Compatible liquids and solids are those which have no detrimental influence on the thermal stability and hazard type of theorganic peroxide formulation.

2.2.52.1.15

Temperature control requirements

The following organic peroxides shall be subject to temperature control during carriage:

- organic peroxides types B and C with an SADT ≤ 50 °C;

- organic peroxides type D showing a medium effect when heated under confinement with an SADT≤50 °C or showing a low or no effect when heated under confinement with an SADT≤45 °C; and

- organic peroxides types E and F with an SADT ≤ 45 °C.

NOTE:Provisions for the determination of the effects of heating under confinement are given in the Manual of Tests and Criteria, Part II, Section 20 and test series E in Section 25.

See7.1.7.

2.2.52.1.16

Where applicable, control and emergency temperatures are listed in 2.2.52.4. The actual temperature during carriage may be lower than the control temperature but shall be selected so as to avoid dangerous separation of phases.

2.2.52.2

Substances not accepted for carriage

Organic peroxides, type A, shall not be accepted for carriage under the provisions of Class5.2 (see Manual of Tests and Criteria, Part II, paragraph20.4.3(a)).

2.2.52.3

2.2.52.4

List of currently assigned organic peroxides in packagings

In the column "Packing Method", codes "OP1" to "OP8" refer to packing methods in 4.1.4.1, packing instruction P520 (see also 4.1.7.1). Organic peroxides to be carried shall fulfil the classification and the control and emergency temperatures (derived from the SADT) as listed. For substances permitted in IBCs, see 4.1.4.2, packing instruction IBC520 and, for those permitted in tanks according to Chapters 4.2 and 4.3, see 4.2.5.2.6, portable tank instruction T23. The formulations listed in packing instruction IBC520 of 4.1.4.2 and in portable tank instruction T23 of 4.2.5.2.6 may also be carried packed in accordance with packing method OP8 of packing instruction P520 of 4.1.4.1, with the same control and emergency temperatures, if applicable.

Class 6.1 Toxic substances

2.2.61.1

Criteria

2.2.61.1.1

The heading of Class 6.1 covers substances of which it is known by experience or regarding which it is presumed from experiments on animals that in relatively small quantities they are able by a single action or by action of short duration to cause damage to human health, or death,by inhalation, by cutaneous absorption or by ingestion.

NOTE:Genetically modified microorganisms and organisms shall be assigned to this Class if they meet the conditions for this Class.

2.2.61.1.2

Substances of Class 6.1 are subdivided as follows:

T Toxic substances without subsidiary hazard:

T1Organic, liquid;
T2Organic, solid;
T3Organometallic substances;
T4Inorganic, liquid;
T5Inorganic, solid;
T6Liquid, used as pesticides;
T7Solid, used as pesticides;
T8Samples;
T9Other toxic substances;
T10Articles;

TFToxic substances, flammable:

TF1Liquid;
TF2Liquid, used as pesticides;
TF3Solid;

TSToxic substances, self-heating, solid;

TWToxic substances, which, in contact with water, emit flammable gases:

TW1Liquid;
TW2Solid;

TOToxic substances, oxidizing:

TO1Liquid;
TO2Solid;

TCToxic substances, corrosive:

TC1Organic, liquid;
TC2Organic, solid;
TC3Inorganic, liquid;
TC4Inorganic, solid;

TFCToxic substances, flammable, corrosive;

TFWToxic substances, flammable, which, in contact with water, emit flammable gases.

2.2.61.1.3

Definition

For the purposes of ADR:

LD50(median lethal dose) for acute oral toxicityis the statistically derived single dose of a substance that can be expected tocause death within 14 days in 50 per cent of young adult albino rats when administered by the oral route. The LD50value is expressed in terms of mass of test substance per mass of test animal (mg/kg);

LD50 for acute dermal toxicityis that dose of the substance which, administered by continuous contact for 24 hours with the bare skin of albino rabbits, is most likely to cause death within 14 days in one half of the animals tested. The number of animals tested shall be sufficient to give a statistically significant result and be in conformity with good pharmacological practice. The result is expressed in milligrams per kg body mass;

LC50 for acute toxicity on inhalationis that concentration of vapour, mist or dust which, administered by continuous inhalation to both male and female young adult albino rats for one hour, is most likely to cause death within 14 days in one half of the animals tested. Asolid substance shall be tested if at least10% (by mass) of its total mass is likely to be dust in a respirable range, e.g. the aerodynamic diameter of that particle-fraction is 10 μm or less. A liquid substance shall be tested if a mist is likely to be generated in a leakage of the transport containment. Both for solid and liquid substances more than90% (bymass) of a specimen prepared for inhalation toxicity shall be in the respirable range as defined above. The result is expressed in milligrams per litre of air for dusts and mists or in millilitres per cubic metre of air (parts per million) for vapours.

2.2.61.1.4

Classification and assignment of packing groups

Substances of Class 6.1 shall be classified in three packing groups according to the degree of danger they present for carriage, as follows

Packing group I: highly toxic substances

Packing group II: toxic substances

Packing group III: slightly toxic substances

2.2.61.1.5

Substances, mixtures, solutions and articles classified in Class 6.1 are listed in Table A of Chapter3.2. The assignment of substances, mixtures and solutions not mentioned by name in Table A of Chapter 3.2 to the relevant entry of sub-section 2.2.61.3 and to the relevant packing group in accordance with the provisions of Chapter2.1, shall be made according to the following criteria in 2.2.61.1.6 to 2.2.61.1.11.

2.2.61.1.6

To assess the degree of toxicity, account shall be taken of human experience of instances of accidental poisoning, as well as special properties possessed by any individual substances: liquid state, high volatility, any special likelihood of cutaneous absorption, and special biological effects.
