Answer :
Final answer:
The correct answer is d) Welding helmet.
Explanation:
Wearing a welding helmet is important for protecting the ears from sparks and spatter, as well as other hazards associated with welding, such as intense light and heat. The helmet covers the entire head, including the ears, and typically has a shield that covers the face to protect the eyes and face from sparks and radiation.The other options, safety goggles, earplugs, and earmuffs, are all important safety equipment for various purposes, but they do not specifically protect the ears from sparks and spatter.
While earplugs and earmuffs are designed to protect against loud noises and can prevent particulate matter from entering the ear canal to some extent, they are primarily used in environments with hazardous noise levels, like construction sites or airports, as noted in the group discussion note. The safety goggles shield the eyes from high-energy particles and harmful radiation, but they do not cover the ears. Hence, for the purpose of protecting the ear canal from spatter and sparks during welding operations, the correct choice is the welding helmet.
