Class 6.2 Infectious Substance Sign

Class 6.2 Infectious Substance Sign – Hazardous Signs

Class 6.2 Infectious Substance Sign – Infectious substances are identified or considered a reasonable substance that contains pathogens. Pathogens are classified as micro-organism including bacteria, viruses, parasites, fungi and other organisms like prions that can trigger human or animal illness. The ‘Class 6.2 Infectious Substance Sign’ warns about possible hazardous materials in transit where there are legal provisions

We supply two compliant versions of the Class 6.2 Infectious Substance sign:

1. Standard Version — Biohazard symbol, wording “Infectious Substance,” and Class 6.2 identifier.

   • Used for general road and sea transport in NZ and AU.

   • Suitable for standard laboratory samples, diagnostic specimens, and controlled infectious shipments.

2. Emergency Instruction Version — Includes additional wording: “In case of damage or leakage immediately notify your public health authority.”

   • Required under IATA air transport regulations and WHO guidelines for high-risk infectious substances.

   • Used when transporting Category A infectious substances (e.g., Ebola, SARS-CoV, Anthrax) by air.

Both versions are compliant with NZS/AS 1319:1994, NZTA, and international dangerous goods regulations. Choose the correct version depending on your transport method and risk category.

FAQ

Q1: Which Infectious Substance sign should I order?
If you are transporting by road or sea, the standard sign is sufficient. If shipping by air, or dealing with Category A infectious pathogens, the version with emergency instructions is required.

Q2: Are both signs compliant with NZ regulations?
Yes — both versions meet NZS/AS 1319:1994 and international requirements. The difference is that the instruction version includes the extra wording required for air transport.

Q3: Can I use the instruction version for all purposes?
Yes, you can — some customers choose the instruction version for consistency across transport modes, but it’s not always required for standard road transport.

Note on 120 mm size: The 120 mm option is not compliant for transport placards, as NZ regulations require a minimum of 250 mm per side for vehicle use. However, it is very useful for small-scale applications such as cylinder cages, storage cabinets, and indoor warning signage where space is limited.

Note on larger sizes (400 mm – 800 mm): While 250 mm is the minimum required size for transport placards, larger signs (400 mm, 600 mm, 800 mm) are recommended for warehouses, depots, bulk storage areas, and outdoor use. The extra size improves long-distance visibility and makes hazards clear to staff, visitors, and emergency responders.

FAQ

1. Why do I need a Class 6.2 Infectious Substance Sign?
   These signs are required under NZS 5433 and UN transport regulations to identify infectious substances that pose risks to human or animal health. They reduce the risk of mishandling and ensure compliance.

2. Where should this Class 6.2 Infectious Substance Sign be displayed?
   On vehicles transporting infectious substances, at storage facilities, medical laboratories, waste depots, and anywhere Class 6.2 materials are handled or transported.

3. What materials are available?
   Supplied as laminated adhesive vinyl stickers or mounted on ACM panels — both weatherproof and durable, suitable for indoor and outdoor applications.

•  2: Flammable gases.
•  3: Flammable liquids.
•  4: Flammable solids.
•  5: Oxidising substances.
•  6: Substances toxic to people.
•  8: Corrosive substances.
•  9: Substances toxic to the environment.

Magnetic mounting option for the Class 6.2 Infectious Substance Sign

Flexible, vehicle-grade magnetic placards with the Class 6.2 Infectious Substance Sign printed on premium vinyl, laminated, and mounted to automotive magnetic sheeting. They stick to ferrous steel panels and remove without residue—ideal for vehicles that only carry DG sometimes.

Who they’re for

• Contractors / couriers who transport Dangerous Goods occasionally

• Hire or multi-use vehicles (no permanent signage)

• Sites that swap classes depending on load (quick changeover)

• Size: 250 × 250 mm (meets common road minimums).

• Magnet: vehicle-grade sheet, 0.8–1.0 mm thick (30–40 mil), high-energy.

• Face film: outdoor self-adhesive vinyl + UV laminate (gloss).

• Operating temp: suitable from winter cold to summer heat (typical automotive range).

• Print: high-contrast black/white artwork.

Where they work (and don’t)

• Works on: painted steel panels that are flat, clean, and smooth.

• Doesn’t work on: aluminium, stainless, plastics, composites, heavy body filler; vinyl wraps, ceramic coatings, heavily textured paint.

• If customers have aluminium doors/ute trays, suggest self-adhesive or rigid ACM instead.

Fitment checklist

1. Clean & dry the panel (no wax/polish).

2. Warm, flat magnet—no curl.

3. Apply to flat steel only; press from centre out.

4. Do not bridge panel gaps, ribs or sharp curves.

5. Remove daily to clean/dry both surfaces; store flat.

6. In heavy rain/highway speeds, check edges haven’t lifted.

Care & maintenance

• Remove and wipe after wet weather; store flat (never rolled tight).

• Move position slightly each week to avoid differential fading.

• Avoid use on freshly resprayed paint (allow full cure).

Compliance note

• Magnet is a mounting method. The operator must ensure placards are the correct class, size, and securely affixed for the journey. Some carriers or site rules may require permanent/rigid placards—check your procedure.

NZS/AS 1319:1994 advocates simplicity and clarity in safety signage. To be effective, they should be easy to read and interpret at a glance.

The Standard is about the use of legible text and appropriate, simple symbols.

By simplifying the message, it reduces the risk of misinterpretation, which increases the chances of the sign’s warning or instruction being followed.

Enhancing the signs visibility through placement and colour

Placement and visibility will play a crucial role in the efficiency of safety signs.

The standard states that signs must be positioned near the hazard they are warning about, which ensures that the safety message is relevant. Also it advocates the use of contrasting colours for the background and lettering. This attention to the colour scheme will increase visibility and readability from a reasonable distance, which ensures the message is accessible.
