The transfer <strong>of</strong> hazardous drugs and contaminated<br />

supplies to waste receptacles can cause exposure, as<br />

can the handling <strong>of</strong> these receptacles (e.g. when<br />

closing bags, during transport, etc.).<br />

While the waste receptacles are relatively leakpro<strong>of</strong>,<br />

contaminated fluids may leak out if the receptacle tips<br />

over.<br />

If the waste receptacles are not closed, there is a risk <strong>of</strong><br />

aerosol propagation or vapour diffusion.<br />

Spills constitute an exposure risk due to potential<br />

direct contact with hazardous drugs or their spread into<br />

the air as aerosols or vapours. This may occur at any<br />

step <strong>of</strong> the medication circuit.<br />

Inadequate cleaning increases the exposure <strong>of</strong> all staff<br />

working in areas where hazardous drugs are handled.<br />

Contact with contaminated surfaces (e.g. counters,<br />

furniture, etc.), wastes, excreta, soiled bedding, rags<br />

and mops used to clean contaminated areas (toilets or<br />

floors in the rooms <strong>of</strong> patients who have received<br />

hazardous drugs, preparation or administration areas,<br />

etc.).<br />

Ingestion via contaminated hands or by eating or<br />

drinking in these areas.<br />

Cleaning <strong>of</strong> hazardous drug spills or the stools, urine<br />

or vomitus <strong>of</strong> patients who have received hazardous<br />

drugs.<br />

Laundry Laundry workers Possible contact with contaminated bedding in some<br />

(Chapter 14)<br />

laundries.<br />

Inhalation <strong>of</strong> particles on the sheets in some laundries.<br />
