Final answer:
The greatest hazards from hand tools arise from misuse, improper maintenance, and ergonomic issues, which can lead to injuries, accidents, and long-term health problems for workers.
Step-by-step explanation:
The greatest hazards produced by hand tools result from misuse and improper maintenance, which can lead to injuries, such as cuts, abrasions, and amputations. When tools are not used correctly or are in poor condition, they can malfunction or fail, increasing the risk of workplace accidents. Additionally, using hand tools for extended periods without proper safety measures can cause ergonomic injuries from strain and repetitive motions. It is critical to ensure that hand tools are used for their intended purposes, properly maintained, and that workers are trained in their correct use to minimize these hazards.
