What is an essential feature of safe shooting practices at a range?

Proper signage is a crucial element of safe shooting practices at a range. Signage serves multiple purposes that enhance safety for both shooters and spectators. It provides clear information about range rules, safety protocols, and emergency procedures, ensuring everyone on-site is aware of the specific regulations they must follow.

Additionally, signage can indicate firing lines, no-shoot zones, and the locations of safety equipment like first aid kits or fire extinguishers. By clearly marking these areas and rules, it minimizes the risk of accidents and reinforces the importance of following established safety protocols. This way, shooters can focus on their practices in a structured and secure environment, while everyone else at the range can be informed about safety expectations.

The other options, while they may have their own relevance in particular contexts, don't contribute to safety in the same fundamental manner as proper signage. For example, dark surroundings can adversely affect visibility and increase risk; close proximity to spectators can lead to dangerous situations; and soundproof booths, while potentially reducing noise, may not address the core safety issues associated with shooting ranges.
