Class 1 Division 1.5 Very insensitive explosives, blasting agents
29
What is Class 1 Division 1.6?
Extremely insensitive explosives, detonating articles
30
These are articles that do not have a mass explosion hazard or has a negligible probability of exploding
Class 1 Division 1.6 Extremely insensitive explosives, detonating articles
31
Explain the two general provision of Class 2:Gases
1. At 50 degrees celsius, it should have a vapor pressure with more than 300 hectopascals 2. Must be completely gaseous at 20 degrees celsius and has a standard pressure of 101.3 hectopascals
32
State the 5 physical states of Class 2 Gases?
1. Compressed gas 2. Liquified gas 3. Refrigerated gas 4. Dissolved gas 5. Absorbed gas
33
What is the critical temperature of compressed gas?
-50 degrees celsius
34
This states that when packaged, it is entirely gaseous
Compressed gas
35
This states that when packaged for transport, it is partially liquid
Liquified gas
36
What is the critical temperature of liquified gas?
above -50 degrees celsius
37
State the two distinctions of liquified gas
1. High pressure liquified gas 2. Low pressure liquified gas
38
What is the critical temperature of high pressure liquified gas and low pressure liquified gas/
High pressure: -50 degrees to 65 degrees celsius Low pressure; more than 65 degrees celsius and above
39
When packaged under for transport, it is made partially liquid due to low temperature. Example of this is dry ice
Refrigerated gas
40
These are dissolved into a liquid phase solvent
Dissolved gas
41
These are solids
Absorbed gas
42
What is the class 2 Division 2.1?
