Larry Arrington, Dean The Impact of Safety on Florida Agriculture Florida agriculture, including forestry and fishing, made an annual economic impact of $53 billion in 1998. More than 81,000 people work on the 40,000 farms in the state, and more than 50,000 are employed in other activities related to agriculture. The state's agricultural enterprises range from large citrus, vegetable and cattle operations to small family-operated farms. From 1989 to 1998, there were approximately 240 deaths related to agriculture in Florida, according to data compiled by the Deep-South Agricultural Health and Safety Center. In addition, agriculture has one of the highest injury and death rates among U.S. industries. Safety in Florida agriculture is challenging because: the state's agricultural enterprises are diverse, safety knowledge among workers varies, manual labor is used extensively, the climate creates year-round heat stress. Therefore, it is vital to assist the public in learning about OSHA documents related to agriculture.

Summary of Standard 1910.110 OSHA Standard 1910.110 is useful for any facility in which liquefied petroleum gases are stored. These gases, often referred to as LPG or LP-Gas, include the following, either in pure form or in mixtures: propane, propylene, butanes (normal butane or iso-butane), and butylenes. The standard specifies every aspect of storing, transferring, and transporting LP-gases. Particular concerns of the standard are prevention of excess pressure in storage containers, safety devices, regulators, and electrical installations and other potential sources of ignition.
