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

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.

What is permeation of protective material?

Permeation of a protective material is when something you need protection from is able to pass through some protective material to reach you without seriously altering the structure of the protective material. If a hazardous material is able to permeate something you are using for a protective barrier, it is not a good choice for a barrier.

Is blood a hazardous material and why?

Blood is hazardous because of bloodborne pathogens. A person can contract Hepatitis B, Hepatitis C, and HIV/AIDS from contact with blood through any mucous membrane such as their eyes, nose, mouth and broken skin. In doctors offices and hospitals blood is considered a biohazard. First responders such as police, paramedics and firemen are very careful when dealing with blood at a scene. Housekeeping personnel in some cases and even YOU can be in a situation where blood is a factor and should not be taken lightly. If you happen to be the first person on the scene of an accident where someone is bleeding and you choose to help them, call for help FIRST (police, paramedics, 911, etc.) then use clean rubber gloves if available to protect yourself. More information can be found by doing a web search for "bloodborne pathogens". You may even consider a Red Cross training course on CPR, first aid and bloodborne pathogens to learn more and make yourself prepared.

When diluting acid should you pour water into acid or acid into the water?

Always add the acid to the water. Otherwise the acid can splash you and get on your skin and also if it is a concentrated acid, as you dilute it, a lot of heat is generated, and you want the larger volume of water to be able to absorb that heat.

Water in acid should never be done

Acid in water rarely goes wrong

How many credits do you earn in the Air Force?

The amount of college credit you receive depends on the job you do. More technically involved jobs generally require more training, and therefore offer more credit. It can be as low as 28, or go higher than 70!

Keep in mind, that's just from the training courses you take automatically to do your job. While serving, you can still take college classes, and they will be free!

If you burn something in an open flame should you wear goggles and gloves?

Yes you should wear goggles and gloves as a safety precaution so you don't burn yourself and so the ashes don't blowup into your eyes. In addition if you do not know all the materials you are burning you should also consider wearing a Respirator. (Only after you have been Fit Tested)

What are methods for the safe handling of hazardous waste and hazardous material?

The proper method for handling hazardous waste or other hazardous materials depends entirely on what the material is and what kind of hazard it presents. There is no universal rule that is sufficient of itself.

In most cases disposal of hazardous materials will need to be taken care of by a licensed company as it usually needs to be tested to find out what exactly is being disposed of. A good example and one that usually isn't properly legislated is used oil. Most used oil contains metal particles as well as other fluids that are in your vehicle.

Methods for handling hazardous waste/ materials include:

  • First In and First Out
  • Inspect HM storage area weekly
  • Label all containers
  • Ensure compatible storage
  • Check storage monthly

Methods for disposal of hazardous waste/ materials include:

  • Incineration, i.e. complete burning of waste at temperature of about 1600 degrees Celsius.
  • Landfill. This can creates problems such as soil pollution and ground water pollution through leaching. The thoughtful selection of landfill sites is very important, as the dumping of radioactive wastes at landfill sites can pose serious health problems. Therefore the landfill area should be away from populations.In areas where the terrain permits hazardous waste can be packed in titanium/metallic containers and stored in mountain caverns. This method is best suited for radioactive waste.

How can acid be a health and safety hazard?

Acid is a safety hazard because it corrodes metal, potentially resulting in breakage or leaks of whatever may be contained in a metal drum. It is also a safety hazard because it can corrode living tissue, causing acid burns and potentially killing the victim if there is enough exposure.

Acid is a health hazard because some forms of exposure to airborne acids can result in removal of the enamel from teeth, corrosion of the septum of the nose, irritation or other damage to the eyes and lungs, etc.
