A recent chemical incident at a New Zealand secondary school has highlighted the importance of proactively managing hazardous substances stored in educational facilities.
The school was closed for the remainder of the day after staff discovered what was described as an unstable chemical in a science laboratory. Emergency services attended the scene, and specialist assistance was required to safely assess and remove the substance.
While the incident was managed safely and no injuries were reported, it serves as a timely reminder of the risks associated with ageing, unidentified, or improperly stored chemicals.
At Hazchem, we’ve noticed an increase in enquiries from schools following media coverage of the event. Many are seeking advice around laboratory chemical assessments, hazardous substance inventories, and chemical clear-outs.
“Schools can accumulate chemicals over many years,” says Matt Goddard, Managing Director of Hazchem Services.
“Some substances deteriorate over time, become unstable, lose their labels, or simply remain in storage long after they are no longer required. These situations can create significant safety risks if they aren’t identified and managed properly.”
Chemical waste is one of the highest-risk waste streams. Improper storage or disposal can lead to chemical burns, toxic fumes, fires, and environmental contamination.
We regularly assist schools, laboratories, and educational facilities with the identification, removal, transport, and compliant disposal of unwanted hazardous substances.
With the school holidays approaching, we’re seeing many schools use the break as an opportunity to review chemical stores, remove unwanted substances, and ensure laboratories are safe and compliant before the next term begins.
If your school is considering a chemical assessment or laboratory clear-out, we recommend booking early to secure your preferred dates.
Common items we recommend schools review include:
- Unlabelled or unidentified chemicals
- Expired laboratory reagents
- Damaged, leaking, or corroding containers
- Chemicals that are no longer used in teaching programmes
- Legacy substances that have remained in storage for many years
We provide chemical identification, hazardous waste disposal, dangerous goods transport, and compliant destruction services for schools, laboratories, businesses, and industrial facilities throughout New Zealand.
We also advise schools on how to safely prepare, package, and label chemicals prior to collection.
