six
What is a Class 1 Division 1.1 hazardous material?
(1) Division 1.1 consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously. (2) Division 1.2 consists of explosives that have a projection hazard but not a mass explosion hazard.
What are hazard class divisions?
331 Nine Classes Class 1: Explosives. Class 2: Gases. Class 3: Flammable and Combustible Liquids. Class 4: Flammable Solids.
What are the sub classes of Class 1 explosive?
Subclasses and categories for explosive substances (1) Explosive substances are divided into the subclasses 1.1, 1.2, 1.3, 1.4, 1.5, and 1.6 set out in the table in Part 1 of Schedule 1.
What is classified as a dangerous good?
Dangerous Goods are substances that are corrosive, flammable, explosive, spontaneously combustible, toxic, and oxidising or water reactive. These goods can be deadly and can seriously damage property and the environment. Petrol, LPG, paints, pesticides and acids are examples of commonly used dangerous goods.
What is DOT Hazard Class 9?
Class 9 hazardous materials are miscellaneous hazardous materials. That is, they are materials that present a hazard during transportation, but they do not meet the definition of any other hazard class.
What is a paint sign?
The sign for paint looks like you are slathering paint on a wall. Take your non-dominant hand and hold it vertically as if it were a wall. Using your dominant hand, move it up and down across the wall as if you were painting.
What hazard class is paint?
Hazard classifications
| Hazard classification for flammable liquids | ||
|---|---|---|
| II | 101-140°F (39-60°C) | diesel fuel, motor oil, kerosene, cleaning solvents |
| III-A | 141-199°F (61-93°C) | paints (oil base), linseed oil, mineral oil |
| III-B | 200°F (93°C) or above | paints (oil base), neatsfoot oil |
What is the flash point of diesel?
| Fluids | Flashpoint [12] oF | Autoignition Temperature [13] oF |
|---|---|---|
| Diesel Fuel [ 1, 2, 3, 4] | 100-204 | 350-625 |
| Ethanol (in gasohol) [ 1, 3, 5] | 55 | 685 |
| Gasoline (50-100 octane) [ 1, 2] | -36 to -45 | 536-853 |
| Gasoline (unleaded) [ 4] | -45 | 495-833 |
Will a match ignite diesel?
If you toss a lit match into a puddle of diesel fuel, it’ll go out. In a car, it takes intense pressure or sustained flame to ignite diesel. On the other hand, if you toss a match into a pool of gasoline, it won’t even touch the surface — it ignites the vapors above the surface.
How hot is a diesel fire?
Examples
| Fuel | Flashpoint | Autoignition temperature |
|---|---|---|
| Gasoline (petrol) | <21 °C (70 °F) | 280 °C (536 °F) |
| Diesel (2-D) | >52 °C (126 °F) | 210 °C (410 °F) |
| Jet fuel (A/A-1) | >38 °C (100 °F) | 210 °C (410 °F) |
| Kerosene | >38–72 °C (100–162 °F) | 220 °C (428 °F) |
How is flash point calculated?
Flash points are determined experimentally by heating the liquid in a container and then introducing a small flame just above the liquid surface. The temperature at which there is a flash/ignition is recorded as the flash point. Two general methods are called closed-cup and open-cup.
Why do we calculate flash point?
At that temperature, the vapor pressure of the liquid provides a vapor concentration that equal to the lower flammability limit. The flash point is an important concept in fire investigation and fire protection because it is the lowest temperature at which a risk of fire exists with a given liquid.
What is the flash point of water?
For example, pure ethanol will flash at 12.7°C; a 70% mixture by weight in water will flash at 23°C; and a 24% mixture in water at 60.5°C. Transportation temperature: materials with high flash points may be considered flammable if transported at temperatures above their flash points.
What is flash and fire point?
The observed temperature when the flame momentarily ignites the vapor/air mixture is the Flash Point. The ignitions repeat as the liquid temperature continues to rise. The observed temperature when the burning becomes continuous is the Fire Point.
