Healthcare

Healthcare workers face exposure to hazardous drugs during compounding and administration, anaesthetic gases in operating theatres and recovery areas, and sterilisation chemicals in central sterile supply departments. Many cytotoxic drugs have no published workplace exposure limits, requiring containment verification through surface wipe sampling and air monitoring. Anaesthetic gas scavenging system effectiveness must be verified through personal monitoring.

4 Key Hazards Monitored

Key Hazards

Primary exposure hazards requiring monitoring in this industry sector.

Cytotoxic Drugs

dust

Hazardous drug handling during pharmacy compounding, nursing administration, and cleaning. No published WES for most cytotoxic agents. Surface contamination monitoring and air sampling required to verify containment.

Anaesthetic Gases

voc

Nitrous oxide, sevoflurane, isoflurane, and desflurane in operating theatres and recovery areas. WES for nitrous oxide 25 ppm TWA. Scavenging system effectiveness must be verified.

Ethylene Oxide

voc

Used in sterilisation of heat-sensitive medical devices. IARC Group 1 carcinogen. Incoming WEL changes may apply.

Glutaraldehyde

voc

High-level disinfectant for endoscopes and instruments. Respiratory sensitiser. WES 0.05 ppm ceiling.

Common Analytes

Substances typically included in occupational hygiene sampling proposals for this industry.

Analyte	CAS	Relevance
Nitrous Oxide	10024-97-2	WES 25 ppm TWA. Operating theatre and recovery room monitoring.
Sevoflurane	28523-86-6	WES 20 ppm TWA. Most commonly used volatile anaesthetic in Australia.
Glutaraldehyde	111-30-8	WES 0.05 ppm ceiling. Respiratory sensitiser. Endoscope reprocessing.
Ethylene Oxide	75-21-8	IARC Group 1 carcinogen. Sterilisation departments.

Regulatory Context

Healthcare facilities are workplaces under the WHS Act. The National Standard for the Safe Handling of Cytotoxic Drugs in the Workplace requires containment verification. Anaesthetic gas monitoring is recommended by ANZCA guidelines. Health monitoring is required for workers exposed to listed hazardous chemicals.
