What can be a consequence of ignoring tool maintenance?

Ignoring tool maintenance can lead to a higher risk of accidents. When tools are not properly maintained, they are more likely to malfunction or break during use, which can pose serious safety hazards to the operator and others nearby. For example, a dull blade on a saw can cause kickback, while worn parts can lead to unexpected failures. These situations can result in injuries or even fatalities. Therefore, regular maintenance is crucial not only for the functionality and efficiency of tools but also to ensure the safety of everyone involved in their operation.

While the other options reflect potential issues related to tool maintenance—like increased operational costs due to the need for replacements or injury-related costs—they do not directly highlight the immediate safety implications that result from neglecting maintenance.
