Sulphur on Board? 10 Safety Hacks You Can’t Afford to Miss!

 ⚠️ “Sulphur on Board? 10 Safety Hacks You Can’t Afford to Miss!”

🤔 Are You Ready to Handle Sulphur Like a Pro?

• Did you know that wet Sulphur can corrode your vessel’s structure?
• Are your crew and systems prepared to handle Group C cargo safely?
• Have you implemented the 3 critical steps that prevent costly bilge damage?

 

🔍 Clause Breakdown & Expert Insights

Cargo: Sulphur
Group: C (Not liable to liquefy)
Angle of Repose: Not applicable
Stowage Factor (SF): Typically between 0.74–1.11 m³/t

🔎 Pro Tip: Always confirm exact SF with charterers, shippers, or agents before stowage planning.

Physical Properties:

• Yellow, odourless solid
• Insoluble in water
• Corrosive when wet due to acidic reactions

💡 Operational Implications & Risks

• Sulphur is classified under IMSBC Code Group C, but that doesn't mean it's risk-free.
• When wet, it produces acidic solutions that corrode tank tops, bilge wells, and pumps.
• Residual dust is also harmful to exposed machinery and crew health.

 

🚩 Top Pitfalls Operators Must Avoid

1. 🔥 Using seawater for fire extinguishing—can cause chemical reactions and intensify damage.
2. ❌ Skipping proper bilge maintenance—corrosion and pump failure are likely.
3. 🚫 Neglecting fresh water wash after discharge—can lead to long-term structural deterioration.

 

✅ Real-World Safety & Efficiency Checklist

🔧 Before Loading:

• Wash and dry holds thoroughly (sea + fresh water)
• Apply protective coating (Chemical or Lime wash)
• Ensure holds meet “Grain Clean” standards
• Obtain:
• Shipper’s Declaration
• MSDS
• Dangerous Cargo Declaration

🚢 During Carriage:

• Strict No Smoking policy on deck
• Ensure hatches are well sealed
• Recirculate air-conditioning; use filters
• Monitor bilges regularly; maintain records
• All crew to wear masks, goggles, and PPE

💧 Fire Protocol:

• Use fresh water OR cover with Sulphur (smothering method)
• Never use seawater

🧪 Bilge Management:

• Check pH value regularly (Litmus paper)
• Pump out water to below tank-top
• After each pump-out, run sea-to-sea educator
• Add neutralizing chemical in bilge pipe

🧼 Post Discharge:

• Remove all residue
• Wash thoroughly with only fresh water
• Request ample FW supply at discharge port from charterers

 

📌 Action Points for Operators, Owners, and Charterers

• 🔍 Survey the holds pre-load with attention to cleanliness and coating integrity.
• 🧾 Document all bilge soundings, pH checks, and chemical treatments.
• 📤 Share MSDS and DGD with all departments and crew for pre-sailing prep.
• 🚫 Enforce PPE and no-smoking policies—non-compliance invites liability.
• 📦 Store & secure all sensitive equipment away from Sulphur dust zones.
