DESPATCH INCIDENT

Accident description.

  • On Saturday October 30th a fire occurred in the Natref despatch area when a road tanker, whilst loading, overfilled. The spill occurred when approximately half the tanker compartment volume was loaded.

DESPATCH INCIDENT

Investigation status

  • Incident was reported to SAPS and DOL - site visits on same day

  • Internal investigation held on 30 October - possible causes identified and revised procedures proposed

  • Results of further technical investigations by independent experts

  • Investigation was conducted by DOL with all relevant parties present on 26 November.

  • Dossier finalised on 18 February and to be handed to state prosecutor

  • Most probable cause of accident - mechanical defect on tanker truck

  • Mechanical defects on service provider road tanker caused by inadequate maintenance practices


Natref regrets the occurrence of recent accidents and the impact on those affected

DESPATCH INCIDENT

Corrective actions (1)

  • DOL Prohibition Notices were immediately implemented

    • Upgrade training by tanker service providers

    • No flood loading allowed

    • Vehicle not idling, lights switched off, battery isolated, earthed

    • Compartment hatches closed

    • Verify loading volume request versus compartment capacity

  • Supervision increased

  • Operating procedures were revised and implemented (including training)

  • New documentation (inspection check lists & driver declarations)


Natref regrets the occurrence of recent accidents and the impact on those affected

DESPATCH INCIDENT

Corrective actions (2)

  • Prevention of product spillage is pro-actively managed by:

    • Pressure testing of vehicle prior to loading

    • Stop loading in gantry if mechanical failure occurs

    • Transporter demerit system resulting in vehicle, driver or fleet suspensions

    • Root Cause Analysis of each spillage incident in co-operation with Transporter

  • Hardware installation to link the overfill protection system on vehicles to loading de-activation in progress

HF ALKYLATION UNIT INCIDENT

Process description (more than 250 units worldwide)

  • Production of high octane petrol from LPG (Butane, butylene)

  • The catalyst used in the process is Hydrofluoric acid (HF)

  • HF is a hazardous chemical which is a strong acid as well as toxic

  • Precautionary measures to handle HF acid (standard procedure)

    • Acid resistant metallurgy used to ensure containment

    • People protection through acid resistant protective clothing (PPE)

    • People protection through restricted access

    • Early warning systems to indicate loss of containment (leak detectors)

    • Training and re-training of personnel working in the unit


Natref regrets the occurrence of recent accidents and the impact on those affected

HF ALKYLATION UNIT INCIDENTIncident description

  • Shut down procedure of the Alkylation plant was started on 23/1/05

  • Shutdown procedure typically takes 7 days and entails the following:

    • Separation of acid and hydrocarbons

    • Safe storage of acid

    • Evacuation of hydrocarbons to safe storage

    • Neutralisation of process equipment to allow safe entry for repairs

  • On 26/1/05, while the acid was being recovered:

    • A gas leak was noticed by plant personnel and the alarm was raised

    • The leaking gas ignited and resulted in a fire

  • The site emergency plan was initiated

    • Site emergency personnel were deployed and combated the fire

    • Personnel not directly involved were evacuated to muster points
