The phrase "look out for" means to be watchful or attentive to the needs or well-being of someone. In the context of the sentence, it suggests that one should always be vigilant and attentive towards their fellow students and co-workers, indicating a sense of care and concern. This makes it the most suitable option among the given choices.

Eye protection can be worn over prescription glasses because many types of eye protection, such as safety goggles or face shields, are designed to fit comfortably over regular prescription glasses. This allows individuals who require prescription glasses to still have the necessary eye protection when working in potentially hazardous environments. Wearing eye protection over prescription glasses ensures that both the eyes and the corrective lenses are adequately protected from any potential dangers, making it a practical and safe solution.

The correct answer is that the welder needs to have hands, arms, legs, and torso covered with durable flame-resistant clothing. This is because welding involves high temperatures and sparks, which can cause burns and ignite flammable materials. Wearing a short-sleeved shirt leaves the arms exposed to potential burns, so it is important for the welder to wear clothing that provides full coverage and protection against flames. The welding helmet, right lens shade, and safety glasses are important for eye protection, but they do not address the need for clothing protection.

Safety glasses are necessary when entering a welding shop to protect the eyes from flying sparks, debris, and harmful radiation. Welding helmets are also important for protecting the face and head, but safety glasses specifically protect the eyes. Welding clothes may be recommended for additional protection, but the most essential item to wear in a welding shop is safety glasses.

It's critical never to use oil or any grease on gas cylinders, regulators, connections, or hoses, especially with oxygen cylinders, as oil can react explosively with oxygen, leading to fire hazards. Using oil or grease in these situations poses a serious safety risk. Instead, only materials compatible with the gas being used should be applied to these components.

It is important to never operate ungrounded equipment. Grounding is a safety measure that helps to protect against electric shock. Ungrounded equipment lacks this protection and can pose a significant risk to the operator.

Engaging in horseplay, which refers to rough or rowdy play, can lead to accidents, injuries, or damage to property. It is important to avoid such behavior to maintain a safe environment. Additionally, unsupervised welding can also be dangerous as it involves working with high temperatures and potentially hazardous materials. Therefore, the correct answer is "Both 1 and 2" as both horseplay of any kind and unsupervised welding should be avoided.

Using a #4 and #6 shade welding lens together will not provide the same level of protection as a #10 shade lens. The shade number indicates the level of darkness the lens provides, with higher numbers indicating darker lenses. A #10 shade lens offers more protection from the intense light and radiation produced during welding compared to a #4 or #6 shade lens. Therefore, using a combination of #4 and #6 lenses will not provide the same level of protection as a #10 shade lens.

Putting up a protective curtain around the welding area is the best solution to prevent the arc flash from being visible to people who have to walk to the shop office. This will effectively block the arc flash and ensure the safety of the individuals passing by. Directing people to take another route or providing shaded lens safety glasses may not fully protect them from the potential hazards of the arc flash. Therefore, the most appropriate measure is to install a protective curtain.
