Question: 1 / 400

Which of the following is an example of an OSHA-required sharp with engineered injury protection?

A self-sheathing needle attached to a dental anesthetic syringe

The self-sheathing needle attached to a dental anesthetic syringe is an example of an OSHA-required sharp with engineered injury protection because it has a built-in safety feature that covers the sharp point after use, preventing accidental needle sticks. Option B is incorrect because it is a standard hypodermic needle without any special safety features. Option C is incorrect because a traditional scalpel does not have any built-in safety measures, making it hazardous to use. Option D is incorrect because a reusable syringe does not have any engineered injury protection and therefore does not fulfill the OSHA requirement.
