Dangerous goods are solids, liquids, or gases that can harm people, other living organisms, property, or the environment. They are often subject to chemical regulations. "HazMat teams" are personnel specially trained to handle dangerous goods. Dangerous goods include materials that are radioactive, flammable, explosive, corrosive, oxidizing, asphyxiating, biohazardous, toxic, pathogenic, or allergenic. Also included are physical conditions such as compressed gases and liquids or hot materials, including all goods containing such materials or chemicals, or may have other characteristics that render them hazardous in specific circumstances.

Dangerous goods are often indicated by diamond-shaped signage. The colours of each diamond in a way has reference to its hazard i.e.: Flammable = red because fire and heat are generally of red colour, Explosive = orange, because mixing red (flammable) with yellow (oxidising agent) creates orange. Non Flammable Non Toxic Gas = green, due to all compressed air vessels being this colour in France after World War II. France is where the diamond system of HazMat identification originated.

Eden Hazard (born 7 January 1991) is a Belgian international footballer who currently plays for French club Lille in Ligue 1 and the Belgium national team. He primarily plays as an attacking midfielder and a winger. Hazard is known for his creativity, speed, and technical ability and is described as a "fearless, explosive attacking midfielder who can change the game with a turn of pace or a dribble". He has also been described as "a defender's nightmare" and has earned critical acclaim for his playing style, which has led to the media, coaches, and players drawing comparisons to FIFA World Player of the Year winners Lionel Messi and Cristiano Ronaldo.

Hazard is the son of former Belgian footballers and began his football career in Belgium playing for local clubs Royal Stade Brainois and Tubize. In 2005, he moved to France joining first division club Lille. Hazard spent two years in the club's academy and, at the age of 16, made his professional debut in November 2007. In his first full season as a starter, he won the National Union of Professional Footballers (UNFP) Young Player of the Year award becoming the first non-French player to win the award. In the 2009–10 season, Hazard captured the award again becoming the first player to win the award twice. He was also named to the league's Team of the Year. Since making his debut in 2007, Hazard has become an integral part of the club under manager Rudi Garcia racking up over 190 appearances. In the 2010–11 season, he was a part of the Lille team that won the league and cup double and, as a result of his performances, was named the UNFP Ligue 1 Player of the Year becoming the youngest player to win the award. Hazard was also given the Bravo Award by Italian magazine Guerin Sportivo for his performances during the 2010–11 season.

United States Navy Commodore Oliver Hazard Perry (August 23, 1785 – August 23, 1819) was born in South Kingstown, Rhode Island, the son of USN Captain Christopher Raymond Perry and Sarah Wallace Alexander, a direct descendant of William Wallace. He was an older brother to Commodore Matthew Calbraith Perry who compelled the opening of Japan to the West by threat of force.

He served in the War of 1812 against Britain. After supervising the building of a fleet at Erie, Pennsylvania, at the age of 27 earned the title "Hero of Lake Erie" for leading American forces in a decisive naval victory at the Battle of Lake Erie, receiving a Congressional Gold Medal and the Thanks of Congress. His leadership materially aided the successful outcomes of all nine Lake Erie military campaign victories, and the fleet victory was a turning point in the battle for the west in the War of 1812.

Perry became embroiled in a long standing and festering controversy with the Commander of the USS Niagara, Captain Jesse Elliott over their conduct in the battle, and both were the subject of official charges that were lodged. In 1815, he successfully commanded the Java in the Mediterranean during the Second Barbary War. So seminal was his career that he was lionized in the press (being the subject of scores of books and articles), has been heavily memorialized, and many places and ships have been named in his honor.
