Question 100Safety & Environmental - QMED
70% to passA low velocity fog applicator is held in an all-purpose nozzle by a bayonet joint. The applicator is prevented from rotating in the joint by _______________.
Aa spring-loaded catch
Ba locknut
Ca keeper screw
Dwater pressure
AI Explanation
The correct answer is A) a spring-loaded catch. The low velocity fog applicator is held in place by a bayonet joint, which is a type of quick-release coupling. To prevent the applicator from rotating within the joint, a spring-loaded catch is used to lock it in place. This spring-loaded mechanism engages with a groove or detent in the applicator, securely holding it in position and preventing unwanted rotation. The other options are incorrect because: B) a locknut would not be used in this type of bayonet joint connection, C) a keeper screw is not a common method for securing the applicator, and D) water pressure alone would not be sufficient to prevent rotation of the applicator within the joint.
