Beware...
Many common items used everyday in the home or workplace may seem harmless, however, when transported by air, they can be very dangerous. In flight, variations in temperature and pressure can cause items to leak, generate toxic fumes or start a fire.
It's the Law...
You must declare your hazardous materials to the airline, air package carrier, or U.S. Postal Service. Violators of Federal hazardous Materials Regulations (49 CFR parts 171-180) may be subject to a civil penalty of up to $27,500 for each violation and, in appropriate cases, a criminal penalty of up to $500,000 and/or imprisonment of up to 5 years.
