The employer is responsible for making sure that PPE fits each worker properly.

Quick Scoop: Who must ensure PPE fits?

In most workplace safety systems, it is the employer (and their managers/supervisors as part of the employer’s duty) who must:

  • Assess hazards and decide what PPE is needed.
  • Provide PPE at no cost to workers.
  • Ensure the PPE fits each worker correctly and is suitable for the specific risks.
  • Replace or adjust PPE if it is damaged, uncomfortable, or the wrong size.
  • Train workers on how to use, wear, and look after PPE.

Many training and quiz-style resources phrase this as a direct Q&A:

“Who is responsible for making sure that PPE fits each worker properly?”
Correct answer: Employer.

Workers still have responsibilities: they must wear PPE as instructed, choose a size that fits when options are offered, and report if something doesn’t fit or is defective. But the legal duty to provide suitable, correctly fitting PPE and to fix fit problems rests with the employer.

TL;DR:
If you see this as a multiple-choice question (Employee vs. Employer), the best answer is: Employer.
