When it comes to paint mixing rooms, safety is not a “nice to have”, it’s the difference between a smooth operation and a serious hazard. In New Zealand, Worksafe and local council regulations require strict compliance around ventilation, fire prevention, and electrical systems.
As any business owner in the automotive, industrial, or marine coating sector knows, a paint mixing room inspection is a critical checkpoint. Fail it, and you could face downtime, fines, or even insurance trouble. Pass it, and you’ve not only ticked the compliance box, you’ve also shown your team and customers that you take safety and quality seriously.
At Legacy Electrical, we’ve helped countless Kiwi businesses get their paint mixing rooms inspection-ready, and in doing so, we’ve seen the same violations crop up time and again. Today, we’ll walk you through the top 10 common violations and, more importantly, how to avoid them before your next inspection.
1. Inadequate Ventilation
The Violation: Poor air circulation leads to the build-up of hazardous vapours, which can be toxic and highly flammable.
The Fix: Install an exhaust system designed to meet AS/NZS 4114 standards, ensuring airflow is directed away from ignition sources. Legacy Electrical often partners with ventilation specialists to ensure the system is not only compliant but also energy-efficient.
Sales Insight: Well-designed ventilation isn’t just about passing inspections extends equipment life, improves worker health, and reduces fire risk, saving you money long term.
2. Non-Explosion-Proof Electrical Fittings
The Violation: Using standard switches, lights, or wiring inside a hazardous area is a common cause for failure.
The Fix: Fit all electrical components in the paint mixing room with certified explosion-proof enclosures as per AS/NZS 60079 standards. At Legacy Electrical, we supply and install rated gear designed for the volatile organic compound (VOC) environment.
Sales Insight: Think of this as “insurance you can touch”, spending a bit more on the right fittings now saves thousands later.
3. Improper Storage of Flammable Liquids
The Violation: Storing more than the allowed amount of paint or solvent outside of a compliant cabinet.
The Fix: Use approved flammable storage cabinets with correct signage. Keep bulk supplies in a separate, ventilated store.
Sales Insight: Organised, compliant storage also makes workflow smoother and reduces waste from spillage or contamination.
4. No Automatic Fire Suppression System
The Violation: Many small shops rely solely on handheld extinguishers.
The Fix: Install an automatic fire suppression system rated for paint and solvent fires. This is often the first thing an inspector will check.
Sales Insight: Fire suppression can lower your insurance premiums, a selling point worth considering.
5. Ignoring Electrical for Ancillary Systems
The Violation: Overlooking safe electrical setups for connected systems such as electrical for septic units managing wash-down waste, can still count against your inspection.
The Fix: Ensure all electrical work for support systems is done by licensed electricians familiar with hazardous areas. Legacy Electrical designs wiring layouts that integrate septic, ventilation, and lighting systems into one safe, compliant package.
Sales Insight: A well-integrated system means fewer call-outs, less downtime, and easier maintenance.
6. Poor Housekeeping Practices
The Violation: Dust build-up, blocked exits, or cluttered work surfaces are red flags for inspectors.
The Fix: Set up daily cleaning protocols and keep clear lines of egress. Regularly empty solvent waste bins.
Sales Insight: Clean, organised spaces impress inspectors and customers alike—it’s a silent marketing tool.
7. Missing or Outdated Safety Signage
The Violation: Faded, missing, or non-standard hazard signs.
The Fix: Update all safety signage to comply with NZS/AS 1319 standards. Make sure they’re visible and legible from a distance.
Sales Insight: Proper signage is one of the cheapest compliance fixes you can make—and it protects your staff.
8. No Documented Safety Procedures
The Violation: Verbal “we all know what to do” doesn’t cut it.
The Fix: Create written SOPs for paint handling, spill response, and equipment maintenance. Keep copies near the work area.
Sales Insight: Documented procedures speed up training and lower the risk of accidents, saving both time and money.
9. Untrained Staff Operating in Hazardous Areas
The Violation: Allowing untrained staff to handle flammable substances or equipment.
The Fix: Provide Worksafe-recognised training on hazardous substances, fire safety, and emergency response.
Sales Insight: Training isn’t just compliance—it boosts morale and professionalism, which customers notice.
10. Outdated Electrical Compliance Certificates
The Violation: Certificates older than the legal inspection period, or missing altogether.
The Fix: Schedule regular electrical inspections with a certified hazardous-area electrician. Legacy Electrical provides full certification so you’re always audit-ready.
Sales Insight: Having up-to-date documentation builds trust with inspectors, insurers, and clients.
