Farm machinery, such as tractors and harvesters, pose significant risks if not handled properly. Warning signs alert workers and visitors to the presence of operating machinery, emphasizing the need for caution to prevent accidents like entanglements or crushing injuries.

Agricultural operations often involve the use of chemicals like pesticides and fertilizers. Exposure to these substances can be harmful. Warning signs indicate areas where chemicals are stored or used, advising individuals to wear appropriate protective equipment and follow safety protocols.
