Correct answer: E — Airborne exposure to latex proteins from powdered gloves used by colleagues in the same environment

Latex proteins can become aerosolised from powdered gloves and trigger respiratory sensitisation in nearby workers who do not directly handle latex. This is a well-documented phenomenon and is the basis for many healthcare facilities switching to powder-free or non-latex gloves.
