Identify the correct pair of Personal Protective Equipment (PPE) categories based on the nature of the hazard.

This question was previously asked in
RRB NTPC 2024 Undergraduate CBT 1 Question Paper (29-Aug-2025) (Shift 1)
The correct answer is

Non-respiratory: Safety helmet, Respiratory: Nose mask

The correct answer is option 2: Non-respiratory: Safety helmet, Respiratory: Nose mask.

Personal Protective Equipment (PPE) is categorized based on the type of hazard it protects against. The categorization is broadly divided into respiratory and non-respiratory protection.

  • Respiratory PPE protects the respiratory system from inhaling hazardous substances like dust, fumes, gases, or vapors. Examples include nose masks, respirators, and full-face respirators.
  • Non-respiratory PPE protects other parts of the body from various hazards. This includes items like safety helmets (protecting the head from falling objects), safety goggles (protecting the eyes from flying debris), safety gloves (protecting hands from chemicals or cuts), safety shoes (protecting feet from falling objects or crushing hazards), and earplugs (protecting hearing from excessive noise).

Option 2 correctly pairs a non-respiratory protective item (safety helmet) with a respiratory protective item (nose mask). The other options incorrectly pair items that don't align with the respiratory/non-respiratory categorization of PPE.
