What is the minimum quantity of gasoline transported on a vehicle requiring hazardous material placards?

Yes. Gasoline is regulated as a hazardous material (flammable liquid) in transportation. Gasoline is a flammable substance and it can harm your health if you have a substantial enough exposure to it.

In the workplace, yes, fibreglas is treated as a hazardous material. However, it is not a regulated hazardous material when being transported.

Yes, a hazardous waste is always a hazardous material, but a hazardous material is not always a hazardous waste.

Yes, if it contains compressed gas that exceeds the non-placard weight limit.

Nitrogen is a hazardous material because if enough of it is released in a confined space it can displace the oxygen and anyone in the space would collapse and perhaps dies from lack of oxygen. That makes it an asphyxiant. It is also hazardous because it is transported in compressed form and can produce an explosion if not handled or packaged properly.

which hazardous material can enter the body

Hazardous material ceases to be hazardous when it is destroyed, sufficiently diluted in nonhazardous material, it is chemically changed into a nonhazardous material or incorporated into an object that immobilizes it and renders it unable to be hazardous.

The Air Force Interservice Manual 24-204 (AFMAN 24-204) definition of Hazardous Material is "A substance or material that is capable of posing an unreasonable risk to health, safety, and property when transported and has been so designated by this manual."

Polystyrene is not a hazardous material (dangerous good) in transportation. However, in circumstances where a fire might be a problem, polystyrene, which can readily and rapidly burn, can be a very hazardous material.

No - it is not usually considered hazardous

A hazardous material is a hazardous material because of its physical or chemical properties, not because of the amount that may be present. Smaller quantities, however, may be considered to be insignificant, but the amount depends on the particular material.

When analyzing a hazardous material incident at the awareness level you are responsible for recognizing the presence of hazardous materials.

When receiving a shipment of hazardous materials, the first thing to do is to determine the nature of the hazardous material and then inspect it to ensure there are no leaks.

In the United Kingdom, fire extinguishers are not considered as hazardous material for transportation by road. Fire extinguishers are considered hazmat for transportation by road and sea and should be accompanied with Dangerous Goods Note and Material Safety Data Sheets. Certain types of fire extinguishers may contain placard-required amounts of hazardous materials, including pressurized CO2 or nitrogen, liquids such as carbon tetrachloride, among other things. Therefore, the answer to the question would depend upon the specific type and quantity of extinguishers being transported.

A hazardous material that is a flammable solid is classified in Division 4.1

As of May 1, 2010, there were four Superfund sites on the National Priorities List in Mississippi, with 2 more waiting to be added. Superfund sites are polluted locations requiring a clean-up of hazardous material contamination.

A Hazardous Waste is any material that is subject to the EPA's Hazardous Waste Manifest specified in 40CFR262. A Hazardous Substance - is any material listed as having Reportable Quantities Pursuant to Section 311 of the Clean Water Act (40CFR117.3) A Hazardous Material is any material or object that meets the any of the definitions of Hazard Classes in 49 CFR or that is listed in the Hazardous Materials Table at 49CFR172.101

Hazardous materials are measured by weight or volume, depending on which material is being measured.

identify the criteria that determines a substance as being a hazardous material

The introduction of a hazardous material into a body of water is called water pollution.

If the hazardous material has been released in an uncontrolled manner, moveaway from the hazardous material. If the hazardous materials are enclosed and controlled, you need not move in any particular direction.

There are weight limits in some situations, transportation, for instance, and not in others.
