The "mean" of a group of numbers is their "average". It doesn't tell you what the numbers are, or even how many numbers there are.
No, the geometric mean is not the same as the mean of two numbers.
Given a set of numbers, and its mean, we can find the difference between each of the numbers and the mean. If we take the mean of these differences, the result is called the mean deviation of the numbers.
Mean = Total of the numbers / n So total of the numbers = n*mean
To take the mean of a set of numbers is just to take the average of the set of numbers. Add all the numbers together and divide this total by the amount of numbers you had. This is the mean.
In the US and most of the world, hazardous materials placards do not carry words, only icons and numbers. So the question of language does not arise.
The DOT system of placards and labels classifies hazardous materials according to their type of hazard, i.e. radioactive, corrosive, flammable liquid, etc.
Placards are not used in maritime shipping of hazardous materials. Even in US ground transportation, placards are not required for the shipment of "Limited Quantities."
Hazardous materials identified in vehicles and rail cars through the use of placards.
No, the placards on a military van container do not meet the requirement for placarding a vehicle. The vehicle itself must be appropriately placarded according to the hazardous materials regulations, which include displaying the correct placards based on the type and quantity of hazardous materials being transported. Simply having placards on the container is insufficient for compliance with vehicle placarding requirements.
A hazardous materials placard is a standardized sign used to identify the presence of dangerous substances during transport or storage. These placards feature specific colors, symbols, and numbers to indicate the type of hazard, such as flammability, toxicity, or radioactivity. They are crucial for ensuring safety and compliance with regulations, allowing emergency responders and workers to quickly assess risks associated with the materials. Proper use of these placards helps prevent accidents and ensures the safe handling of hazardous materials.
The shipper is typically responsible for providing the required placards to the carrier transporting hazardous materials. Placards communicate essential information about the hazards present in the shipment and are required by transportation regulations to ensure the safety of the carrier and others on the road.
what do you mean the bloody placards
Danger placards must be used when hazardous materials are being transported on highways, railways, or waterways. They alert emergency responders and the public to the specific risks associated with the materials being transported. Placards are required for Class 9 materials, elevated temperature materials, and select organic peroxides.
No. If you get into an accident, first responders are going to see the placards and assume the hazardous materials are loaded on the trailer. If you're in a state where you're unable to communicate with them, they're not going to be aware that there are hazardous materials in the cab of the power unit.

It's determined by weight. Gasoline is Hazard Class 3, which requires placards to be displayed if more than 1,000 lbs. of it is being transported. One gallon of petrol weighs between 5.8 and 6.5 lbs, so you'd be looking at 153 to gallons (roughly) before placards had to be displayed.
