Which type of safeguarding method includes two-hand control and pull backs?

The correct answer emphasizes point of operation safeguards, which are specifically designed to protect workers from hazards that occur at the point of operation of machinery. Two-hand control and pull backs are two examples of safeguarding methods that fall under this category.

Two-hand control requires the operator to use both hands to operate the machine, ensuring that their hands are kept away from potentially dangerous moving parts during operation. This reduces the risk of accidental injury significantly. Pullback devices, on the other hand, utilize a system that restrains the operator's hands and pulls them back from the danger zone when the machine is in operation. Both methods provide a level of active safety, requiring the operator’s engagement while effectively minimizing the risk of contact with hazardous areas.

While locking mechanisms can prevent machinery from being operated unintentionally, and enclosed barriers restrict access to dangerous areas, they do not include the interactive safety features that are essential in two-hand control setups. Emergency procedures are broader in scope and focus on responses in case an incident occurs, rather than direct operational safeguarding methods.
