Casinos are subject to specific regulations for worker safety, as casino employees are both at greater risk for cancers resulting from exposure to second-hand tobacco smoke and musculoskeletal injuries from repetitive motions while running table games over many hours. When it opened in 1989, The Mirage was the first casino to use cameras full-time on all table games. Some casinos also have catwalks in the ceiling above the casino floor, which allow surveillance personnel to look directly down, through one way glass, on the activities at the tables and slot machines. Given the large amounts of currency handled within a casino, both patrons and staff may be tempted to cheat and steal, in collusion or independently; casinos have security measures to prevent this. In Vietnam, the term “casinos” encompasses gambling activities within the country.<\/p>\n
