Dialectal Variation
British vs American Usage

Connotations
Neutral/technical in both. Slightly more formal in American English when used outside firearm contexts.
Frequency
More frequent in British English. In American English, 'safety latch' or 'safety lock' are common alternatives for non-firearm items.

Common Mistakes
- Using 'safety cap' or 'safety cover' for a catch mechanism. Confusing 'safety catch' (prevents operation) with 'safety belt' (restrains).
