If your business uses a spray booth—even if it’s just occasionally—you’re already working in a high-risk zone. It only takes one overlooked filter, one faulty fan, or one mismanaged paint mixing area to invite fire, legal liability, and complete operational shutdown.
That’s where AS/NZS 4114.1 compliance comes into the picture.
But here’s the challenge: many businesses in manufacturing, automotive, or industrial finishing think that being “mostly compliant” is enough. Spoiler alert—it’s not. AS/NZS 4114.1, the National Fire Protection Association’s code for spray application using flammable or combustible materials, is very clear and very enforceable.
If your spray booth inspection hasn’t had a proper inspection in months (or years), this guide is for you.
At Legacy Electrical, we’ve helped workshops, manufacturers, and spray facilities across New Zealand meet and maintain top-tier safety standards—and we know exactly what goes into a safe, code-compliant operation.

Why AS/NZS 4114.1 Compliance Isn’t Optional
Let’s start by clarifying something critical: AS/NZS 4114.1 is not just an American code. It is widely adopted across international industries, especially by insurers, auditors, and multinational corporations operating in New Zealand. If you’re dealing with volatile finishes, solvents, or paints, this standard becomes the benchmark for fire safety—even if local regulations don’t spell it out word for word.
In short, being AS/NZS 4114.1 compliant means you’re serious about safety, liability reduction, and operational excellence.
Failure to comply can result in:
- Insurance claim denials in the event of fire
- Penalties or shutdowns during audits
- Massive reputational damage
So how do you stay compliant? It starts with a professional spray booth inspection—done regularly and thoroughly.
What Is a Spray Booth Inspection, and Why Does It Matter?
A spray booth inspection is a comprehensive review of your spray booth’s structure, systems, and airflow dynamics. It’s not just a tick-box exercise. You’re identifying real-life hazards that could lead to a fire, contamination, or non-compliance.
Here’s what’s typically reviewed:
- Airflow rates and exhaust velocities
- Filter condition and placement
- Fire suppression systems
- Lighting and explosion-proof wiring
- Grounding and bonding of metal parts
- Accumulated overspray and flammable residue
If any of these systems fail—or are even slightly off—you’re looking at a potentially life-threatening environment.
At Legacy Electrical, we’ve seen firsthand how tiny oversights become major liabilities. A clogged exhaust duct might not seem like much… until it catches a spark. That’s why we follow AS/NZS 4114.1 Section 7 and 9 guidelines to the letter during inspections.
Paint Mixing Room Inspection: Don’t Overlook the Danger Next Door
Too often, businesses focus solely on the booth itself while ignoring the area where the flammable magic happens—the paint mixing room.
AS/NZS 4114.1 (Section 5.5) requires that paint mixing rooms:
- Are isolated and ventilated
- Use explosion-proof electrical components
- Include spill containment measures
- Maintain strict controls over ignition sources
A proper paint mixing room inspection ensures you’re not letting a hidden fire hazard operate just metres away from your spray booth. We always tell clients: your compliance is only as strong as the weakest room in the building.
7 Non-Negotiable Tips for Spray Booth Inspection & AS/NZS 4114.1 Compliance
If you’re unsure where to begin, these inspection tips will help you steer clear of costly violations and dangerous oversights.
1. Check Airflow with a Manometer or Anemometer
Proper airflow prevents overspray accumulation and ensures fume extraction. If you’re not measuring it, you’re guessing—and that’s risky.
2. Inspect and Replace Filters Regularly
Clogged filters not only reduce efficiency but become prime fuel for fire. Make this a non-negotiable part of your maintenance schedule.
3. Confirm All Electrical Components Are Explosion-Proof
From lights to fans, everything in and around your booth must meet Class I, Division 1 standards. Regular spray booth inspections help identify outdated or unsafe fittings.
4. Document Cleaning and Maintenance
AS/NZS 4114.1 requires written proof of booth cleaning, filter changes, and system maintenance. No paperwork? No compliance.
5. Test Fire Suppression Systems Annually
Automatic extinguishing systems need professional inspection—especially if you’ve never actually had to use them.
6. Don’t Use Your Booth for Storage
It’s common to store paint cans or tools inside a booth “just for a moment”—but it’s strictly prohibited under AS/NZS 4114.1. Keep the space clean and clear at all times.
7. Schedule a Full Paint Mixing Room Inspection
Your spray booth can be spotless, but if your mixing room is non-compliant, you’re still exposed. Ventilation, grounding, and chemical storage should all meet inspection criteria.

The Cost of Non-Compliance: What’s Really at Stake?
Let’s be blunt—a non-compliant spray booth isn’t just unsafe. It’s a financial ticking time bomb.
- Insurance risk: Providers may refuse payouts for fires linked to neglected inspections or out-of-code equipment.
- Fines and legal exposure: Under NZ workplace health and safety laws, negligence that leads to injury or fire can result in prosecution.
- Production delays: If your booth is shut down due to a failed inspection, your entire operation could grind to a halt.
Investing in a professional spray booth inspection is not a cost—it’s a safeguard.
When Should You Schedule Your Next Inspection?
If you’re asking, “Do I really need this now?”—the answer is probably yes.
We recommend:
- Quarterly visual inspections (in-house or outsourced)
- Annual professional inspections by qualified specialists
- Immediate inspections after any equipment change, fire event, or layout alteration
And don’t forget to include a paint mixing room inspection in your yearly schedule. These areas are too often overlooked—and just as high-risk as the booths themselves.
Final Thoughts: Safety Isn’t Just a Code—It’s a Culture
At the end of the day, AS/NZS 4114.1 compliance isn’t about avoiding penalties. It’s about creating a work environment where your team feels safe, your equipment performs reliably, and your operations stay uninterrupted.
Whether you’re a high-volume manufacturer or a boutique refinisher, spray booth inspections and paint mixing room safety need to be non-negotiables.
