What essential safety equipment is recommended for a launcher during a launch?

The recommendation for safety glasses and suitable personal protective equipment during a launch is grounded in the need to protect oneself from potential hazards associated with rocketry operations. Safety glasses are essential as they shield the eyes from debris, propellant emissions, or any unexpected events that may occur during a launch. This equipment is particularly important when dealing with rocket motors and various materials that can pose risks of injury.

Additionally, "suitable personal protective equipment" encompasses a broad range of items that could include gloves, flame-resistant gear, or other specific items depending on the environment and expected risks of the launch. Having such equipment on hand helps ensure that individuals are well-equipped to handle potential emergencies or accidents.

While the other options mention various safety items, they do not provide a comprehensive focus on the core protective measures specifically aligned with the direct hazards present during a rocketry launch.
