  The Occupational Safety and Heath Administration, under the U.S. Department of Labor, sets safety regulations for all U.S. industry. Any person who employs one or more persons in an agricultural occupation must abide by OSHA regulations. OSHA will only spend time and funding to enforce regulations on agricultural operations employing 10 or more persons, unless the laborers set up a temporary camp. An employer with 10 or more persons must keep all records pertaining to injury or illness of workers for the U.S. Department of Labor.
  
  

Slow-Moving Vehicles

• Any vehicle on a public roadway moving at speeds of 25 miles per hour or less must display a slow-moving vehicle sign. According to the OSHA website, the emblem is "a fluorescent yellow-orange triangle with a dark red reflective border". The sign should be displayed on the back of the slow-moving vehicle, 2 to 6 feet from the ground, and in clear sight of any vehicles that may be behind it.
  
  

Machinery Guarding

• The farm owner must ensure all exposed or accessible moving parts of machinery are guarded with a properly installed shield guard, fence or guardrail. All guards must be strong enough to withhold the weight of a 250-pound person leaning or falling on them.
  
  

Roll-Over Protective Structures

• The farm owner must equip all tractors and other agricultural equipment with roll bars or other protective enclosures to prevent severe injury in the case of roll-over or other machinery upset. Moreover, clearance from the ground to the chassis may not exceed 18 inches, and the hood level must not exceed 60 inches. The farm owner must equip all machinery with durable seat belts.
  
  

Labor Camps

• If workers are living in camps on the site, a farm employer is responsible for additional regulation compliance, regardless of the number of workers employed. The employer must report any accidents, injuries or communicable diseases to OSHA within 48 hours.
  
  In addition, the camps themselves must meet several regulations. The site must be graded and clear of areas prone to flooding, 500 feet from livestock, 200 feet from collections of water, and clean and free from debris. Shelters must protect occupants from the elements, contain windows with screens, provide 50 square feet of space per occupant, and have at least a 7-foot ceiling.
  
  The employer must also provide adequate bedding, storage, cooking, water, bathing, laundry, garbage and toilet facilities. Finally, the employer must take measures to control rodents and pests, and provide an accessible person trained in first aid.
