What importers need to know about bitumen drums: checks on arrival, heating, water and boil-over, hydrogen sulphide, burns, and what the SDS says.
Bitumen Drums: Receiving, Heating and Safe Handling
Bitumen in drums is solid at ambient temperature and has to be heated before it can be used, which is where most handling risk sits. This guide explains what to check when drums arrive, why heating needs care, the hazards that safety data sheets warn about (burns, water, hydrogen sulphide), and what to ask your supplier for. It is general guidance. Your Safety Data Sheet and site procedures take precedence.

Why do bitumen drums need special handling?
Bitumen shipped in metal drums is solid or very viscous at ambient temperature and must be heated before use as a road binder. Moving and emptying drums can be difficult and hazardous when the transporter or the site lacks suitable drum-handling equipment, and some product stays on the drum walls after emptying. Drums suit containerized imports and sites without heated bulk storage, but the buyer must plan how drums will be unloaded, stored and heated before the cargo is booked.
What should you check when drums arrive?
Inspect the shipment before accepting it and keep photographs. These checks catch most problems early.
- Drum condition: no dents that compromise seams, no leaking or bulging, lids and bungs secure.
- Labels and markings: grade, batch number and quantity match the COA and shipping documents.
- Count and weight: the number of drums and stated net weight match the packing list.
- Seals and container condition: check the container seal number against the bill of lading.
- Storage plan: a level, load-bearing area under cover, away from sun and open flame.
How hot can bitumen be heated?
Temperature limits depend on the product, so read the Product Data Sheet and Safety Data Sheet for your exact grade. As general industry guidance, Nynas recommends maximum storage and handling temperatures of 200°C for bitumen and 230°C for oxidized bitumen, and advises keeping the storage temperature at least 30°C below the flash point. Individual safety data sheets are stricter in places: one tells users not to heat above 160°C and another above 177°C. Overheating also hardens bitumen and can change the properties confirmed on the COA, so lower, controlled heating is better than hotter.
How should drums be heated?
Use equipment designed for bitumen drums and follow the manufacturer's and your site's procedure. Supplier guidance is to heat indirectly with approved drum heaters and never to apply direct flame to a sealed drum, because trapped product can build up pressure. Keep heating tubes covered by bitumen while heating, let any moisture evaporate before adding more hot product, and do not leave heated product unattended overnight where the safety data sheet advises against it.
Why is water dangerous around hot bitumen?
Water turns to steam at 100°C and expands violently. Safety data sheets warn that heating bitumen above 100°C in the presence of water can cause splashing, boil-over or violent explosion. Rain on open drums, condensation inside a drum, wet equipment and wet tank walls are common sources. Keep drums and heating equipment dry, store them under cover, and make sure any container receiving hot bitumen is dry.
What other hazards do safety data sheets list?
Three recur on bitumen safety data sheets, so read the one for your product.
- Burns: hot bitumen causes severe thermal burns. Use heat-resistant gloves, face protection and protective clothing, and follow the SDS first-aid instructions. One SDS warns against trying to remove the product from burned skin.
- Hydrogen sulphide: heated bitumen can release hydrogen sulphide, a highly toxic gas that collects in tank headspaces and enclosed spaces. One manufacturer SDS says to evacuate the area if the air concentration exceeds 10 ppm unless respiratory protection is used. Ventilation is the main control.
- Fire: keep ignition sources away from heated product and flammable vapour, particularly if the product is a cutback or has been contaminated with solvent.
What should you ask your supplier to provide?
Request the documents before the cargo ships so your site can prepare. PetroBind Global provides COA and PDS documentation for confirmed lots, and the SDS for the grade you order. Ask in writing for the drum type and net weight, the recommended storage and heating temperature range for the grade, and the packing and loading arrangement. Confirm these during the RFQ, not after the shipment is on the water. See the guides on logistics and packaging and on storage and handling for more.

Frequently Asked Questions
- Q: Why does bitumen in drums have to be heated?
- A: Bitumen is solid or very viscous at ambient temperature, so it must be heated before it can be pumped, mixed or applied.
- Q: Can I heat a sealed bitumen drum directly with a flame?
- A: No. Supplier guidance is to use approved drum heaters and indirect heating, never direct flame on a sealed drum. Follow the SDS and your site procedure.
- Q: What happens if water gets into hot bitumen?
- A: Water above 100°C turns to steam and can cause splashing, boil-over or violent explosion, according to safety data sheets. Keep drums, tanks and equipment dry.
- Q: Is hydrogen sulphide a risk with bitumen?
- A: It can be. Heated bitumen may release hydrogen sulphide, which is toxic and collects in enclosed spaces. Ventilate, and follow the exposure limits on your SDS.
- Q: What temperature should I store bitumen drums at?
- A: Solid drums can be stored at ambient temperature under cover and away from sun and flame. The heating range depends on the grade, so use the PDS and SDS for your product.
- Q: Does PetroBind Global provide a Safety Data Sheet?
- A: PetroBind provides COA and PDS documentation for confirmed lots and the SDS for the grade you order. Ask for them during the RFQ.
