PC‐3 laboratories are contained in 3 large suites (up to ~2000m3/70000ft3)
False ceiling

Australian Animal Health LaboratoryWhat is the problem?
Bundled data & power cables
PC3 Laboratory spaces have never been fumigated.
PC4 and animal spaces ‐ formaldehyde

Compliance alignmentRegulatory audit finding:
• Remove ceiling tiles ‐ Non‐Compliance.
• Must demonstrate fumigation is possible – 5 year variation
Fallout
• Major works required – full compliance for recertification
$ $ ($ $ )• AU$250m – AU$800m ($180m ‐ $600m) over 5‐7 years.
• Formaldehyde fumigation not an option for regular treatment

Chlorine DioxideIs this a viable option for us?
• A true gas• Peer laboratories have shown efficacy• Peer laboratories have shown efficacy• No ‘off‐gassing’• Enhanced safety cf. formaldehyde
• Possible to accommodate large spaces

Evaluation of Chlorine DioxideMinimum disruption for maximum time
• Penetration• Dust
• Acoustic tiles
• Bundled cables
• Relevant efficacy
