Sodium Hydroxide Solution Emergency Information Panel Sign

Sodium Hydroxide Solution Emergency Information Panel Sign – EIP Sign

Sodium Hydroxide Solution Emergency Information Panel Sign – The Sodium Hydroxide Solution Emergency Information Panel (EIP) Sign serves a critical role in ensuring safety and providing essential information in environments where sodium hydroxide (caustic soda) solution is used, stored, or transported. Its primary purposes are:

1. Chemical Identification: The sign clearly indicates the presence of sodium hydroxide solution, a highly corrosive substance, so that everyone on-site or responding to an emergency knows the exact chemical involved.
2. Hazard Communication: It informs personnel and first responders about the specific hazards of sodium hydroxide solution, such as its ability to cause severe burns to skin and eyes, as well as its corrosive effects on metals and organic materials. Inhaling the vapors or mist can also cause serious respiratory issues.
3. Safety Precautions: The panel outlines handling and storage safety measures, such as the importance of wearing appropriate personal protective equipment (PPE) like chemical-resistant gloves, goggles, and protective clothing, as well as ensuring proper ventilation to avoid inhalation hazards.
4. Emergency Response Instructions: In the event of a spill or exposure, the sign provides guidance for emergency responders on how to safely manage the situation. This includes instructions for containing the spill, neutralizing the chemical (typically with an acid), and appropriate firefighting methods, as sodium hydroxide solution can react with water and certain metals to produce heat or flammable hydrogen gas.
5. Health and First Aid Procedures: The sign gives critical first aid information, such as flushing affected skin or eyes with large amounts of water in case of contact, and seeking immediate medical attention. It also advises on the steps to take if the solution is ingested or inhaled.

Specialist Advice Field – What To Add

On all Emergency Information Panel (EIP) Signs, there is a section labelled “Specialist Advice”. This is where you can add contact details for immediate technical or emergency response advice.

For example, you can include:

• Company emergency phone number (e.g. 0800 XXX XXX)

• On-site chemical specialist or health & safety officer contact

• Emergency response contractor details (e.g. CHEMCALL, if your company is subscribed, or another provider)

• Internal HSE department contact

👉 If you don’t have a specialist service, you can still include a company name and phone number so first responders know who to contact immediately.

NOTE: If you wish to use 0800 CHEMCALL, please note that this service is operated by Responsible Care NZ and permission/approval must be obtained directly from them prior to use

The Sodium Hydroxide Solution EIP Sign includes key details such as UN 1824, HAZCHEM 2R, and a space for Specialist Advice.
These panels are vital for chemical transport, bulk storage, and emergency response compliance.
Learn how to complete and display EIPs correctly in Emergency Information Panel Signs Explained.

The 2R code indicates that fine water spray can be used to cool containers, but spillage control and protective gear are essential.
It also alerts responders that sodium hydroxide is corrosive and reacts with acids to produce heat.

FAQs

1. Why do I need a Sodium Hydroxide Solution EIP sign?
This sign is required under NZ transport and HSNO rules to identify tankers or containers carrying corrosive liquids like caustic soda. It provides essential details for emergency services and prevents hazardous mix-ups during transport or storage.

2. Where should it be used?
Place on tankers, bulk storage containers, or depot entrances handling Sodium Hydroxide Solution. It should be clearly visible to first responders and staff from a minimum of 10 metres.

3. What can go in the ‘Specialist Advice’ field?
You can include your company’s emergency contact, CHEMCALL 0800 243 622 (if authorised), or a site-specific emergency number. We can print your chosen contact during production.

Caustic soda’s no joke — it’ll eat through grime and a pair of jeans if you’re not careful!
Pair this one with our Ammonia Solution EIP Sign to keep all corrosive substances clearly labelled.

How to choose the right mounting options.

Corflute: short-term term less than 2 years outdoors

Thin PVC: Medium term, more than 2 years

ACM: Long term 5 years or more

Supplied as a sticker:

long-term digital print laminated for long-term use. With a life of 5 years or more. We use a Hi Tac vinyl which allows it to be applied to most surfaces.

Magnetic mounting option for the Sodium Hydroxide Solution Emergency Information Panel Sign

Flexible, vehicle-grade magnetic placards with the Sodium Hydroxide Solution Emergency Information Panel 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)

• 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).

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.
