Final answer:
The chef has the least risk of suffering a hand injury.
Step-by-step explanation:
Based on the information provided, the worker with the least risk of suffering a hand injury would be the chef.
A construction worker often works with heavy machinery, sharp tools, and building materials, and therefore has a higher risk of hand injuries.
A surgeon performs delicate procedures and follows strict protocols, including the use of gloves and other protective equipment, minimizing the risk of hand injuries.
A firefighter deals with hazardous situations that may involve handling equipment or debris, increasing the risk of hand injuries.
On the other hand, a chef's primary tool is cooking utensils, which are designed with ergonomics and safety in mind. Although there is still a risk of cuts or burns, compared to the other options, a chef has the least risk of suffering hand injuries.
