Name and Description

5.5 Organic peroxide mixture

Organic peroxides name table (see Appendix A) in the mixture formulation listed may be assigned to its most dangerous had the same composition as the organic

Oxide type transport conditions for the transport and press the predetermined type of organic peroxide. However, as two stable components can form

Mixture was less thermally stable, self-accelerating decomposition temperature of the mixture should be determined and, if necessary, is applied in accordance with this standard temperature

The degree of control.

Temperature control in claim 6

6.1 temperature controlled conditions

The following organic peroxides in the temperature should be controlled during transport.

a) SADT<=50 °C B and C of the organic peroxide;

b) showing a medium effect through the United Nations "Recommendations on Tests and Criteria hand Transport of Dangerous Goods when heated under confinement

Book "(fifth revised edition) (hereinafter referred to as the" Manual of Tests and Criteria ") contained in the second part of the test series E is determined, and

And significantly low or no effect when the D-type SADT<=45 °C SADT<=50 °C heated under confinement or organic peroxyacids

Thereof;

c) E-type and F-type SADT<=45 °C organic peroxides.

6.2 control and emergency temperatures

Control temperature is the maximum temperature of the substance can be safely transported. Assuming the ambient temperature during transport of the package does not exceed 55 °C, and

Within each 24h only a relatively short time to reach this temperature. Such as temperature out of control, it would be necessary to take urgent measures. Temperature is critical

It refers to the temperature at which should take urgent measures. Reservoir type versus temperature are shown in Table 2.

6.3 Test Method

6.3.1 Test methods for determining the self-accelerating decomposition temperature, see "Manual of Tests and Criteria," Part II, section 28. Select the test should be representative

The actual state of the package to be transported.

6.3.2 to determine the flammability test methods, see Part III, "Manual of Tests and Criteria" Section 32.4. When the organic peroxide is heated since

Violent reaction can occur, a small amount of sample should be used when measuring the flash point, closed cup ISO 3679 as the balancing method.

9.1 regulations

Maintaining the temperature specified essential features of many organic peroxides safe transportation. Organic peroxides should comply with the relevant transport

Provisions.

9.2 Temperature control during transport

9.2.1 necessary procedures

a) thorough inspection before loading on the transport means;

b) cooling system provides instructions to the carrier;

c) measures to improve emergency response;

d) Regular monitoring of the operating temperature;

e) a backup cooling system or a spare part in good condition.

9.2.2 temperature control means

Any control means and temperature sensing means for cooling the system should be easy to close, all of the electrical connections shall be weatherproof erosion. The transport means

Temperature of the air shall consist of two independent sensor measurements, measurements should be recorded in order to be able to easily detect the change in temperature. It should be every

4h ~ 6h checks and records the temperature. When transporting material temperature was controlled below 25 deg.] C, the transport device should be equipped with a temperature alarm which

Powertrain and cooling system separately, to ensure that work at a temperature equal to or below the control temperature.

If the temperature exceeds the control temperature, appropriate measures should be taken, including the cooling device during transport the necessary repairs, or by

Plus cooling capacity (such as adding liquid or solid coolant) should also regularly check the temperature, and is prepared to take emergency measures. If it reaches a critical temperature

Degree, should take urgent measures.

9.2.3 Control mode selection

A temperature control means is suitable for use in transport depends on several factors. Factors that should be considered include.

a) controlling the temperature of the substance to be transported;

b) controlling the temperature difference between the expected ambient temperature conditions;

c) a thermal insulation effectiveness;

d) transport time;

e) reserve safe time.

9.2.4 Temperature Control Method

To increase the temperature control method to prevent exceeding the temperature control to be taken.

a) thermal insulation; however, the initial temperature of the organic peroxide to be sufficiently below the control temperature;

b) with a thermally insulating coolant system.

1) with adequate coolant (e.g., liquid nitrogen or solid carbon dioxide);

2) liquid oxygen or air is not used as coolant;

3) When the most spent coolant, the cooling effect remains uniform;

4) transport means clearly marked warning. "unventilated not allowed";

c) a single mechanical refrigeration. flash point below critical temperature for 5 °C above organic peroxide, used in the cooling compartment with the electrical

Explosion proof member is to prevent ignition of flammable vapors of organic peroxides;

d) using a mechanical refrigeration system combined with the coolant system.

1) two independent systems;

2) in line with b) and c specified) in;

e) two yuan mechanical refrigeration system.

1) In addition to the power supply device in combination, the two systems are separate;

2) Each system has the ability to separately maintain adequate temperature control;

3) a flash point below the critical temperature above 5 °C organic peroxide, used in the cooling compartment is explosion-proof electrical accessory to

Anti-ignite flammable vapor of the organic peroxides.

Note. Due to the different circumstances of different modes of transport to be considered, it provides only general guidelines.
