Introducing dangerous goods safety

  • Storage, handling,

manufacture

  • Transport (road and

rail)

  • Explosives
  • Security sensitive

Transfer

Situation:

  • Road conditions blamed for accident, yet decant in same spot with

road still open and no restrictions?

  • Great Northern Highway has AN, NaCN, explosives, corrosives,

xanthates and diesel tankers

  • Double, triples and quad combinations operating

Controls:

  • Warning signs?
  • Speed restrictions?
  • Emergency Services?
  • Drag tanker from roadside?
  • Risk assessment?

Risks

What is As Low As Reasonably Practicable (ALARP) for transporting dangerous goods? How do you assess risk of transporting ammonium nitrate emulsion in a road train passing through local town with schools and a hospital?

SLIDE 19

Acceptance of Risk

How does your company accept the risk of:

  • transporting goods A/B/C in approved packagings X/Y/Z,
  • from consignors Curly, Dodgy and Rusty,
  • overpacked as per Procedure P1/2/3,
  • consolidated by Loaders Dick & Harry into Freight Container 1
  • with other Portable Tanks PT1 & PT2
  • in a triple-trailer configuration driven by Safety Samantha
  • over a specific pre-determined route
  • to consignees Mining Magnate & Hardwares R US?

Levels of risk assessment

  • Qualitative treatment of each aspect of your transport system
  • Quantitative risk assessment for specific dangerous goods on

specific routes

  • Hazard ID and control
  • HAZOP for tanker transfers, unloading and loading

20

slide-21
SLIDE 21

Using Appropriate Risk Assessment Tools

21

  • Abundance of Risk Management principle guidelines that

align with OSH standards, AS31000

  • ISO 39001:2012 Road traffic safety (RTS) management

system – apply to your depot/ warehouse

  • Paucity of relevant and user-friendly templates for assessing

hazards involved in DG transport activities.

slide-22
SLIDE 22

DMP Approach to DG Transport Risk Assessment

  • Physical hazards - containers and mechanical handling
  • Chemical hazards inherent in DG
  • Consolidating DG loads
  • Loading DG
  • Treating Defective Packaging
  • Load Restraint
  • In-transit procedures
  • Activating Transport Emergency Response Plan
  • Unloading DG to Consignee premises

Consolidating Dangerous Goods Loads

Consignment Issues

  • Transport consignment form does not include DG declaration

 consignor offering DG as general freight

  • Consignment system does not recognise UN No. or DG

Classes  no information for transport documentation, segregation or placarding Overpacking

  • Overpacking technique with black shrink-wrap obscures

incompatible goods  segregation issues

25

slide-26
SLIDE 26

www.dmp.wa.gov.au/ResourcesSafety

Loading Dangerous Goods

Loading Plan

  • No documented load plan means pallets loaded according to

consignee location  poorly planned loads

  • Load plan does not indicate position of DG classes on

combination  poor knowledge of load by company driver or sub-contractor picking up loaded trailers Achieving Effective Segregation Effective Placarding (incl. IBC Emergency Information Panels)

26

slide-27
SLIDE 27

www.dmp.wa.gov.au/ResourcesSafety

Load Restraint

Procedural issues

  • Principles of Load Restraint Guide 2004 not formally adopted

Generic hazards to address Pallets of packages IBCs

  • Flexible IBCs are creased significantly due to solids moving

internally  gradual loosening of strap in-transit Stillages & Cylinders

  • Stillages without lockdown mechanism on base or vehicle

locating pins  unstable loads Placardable Units – Twist Locks

27

slide-28
SLIDE 28

Defective Packaging

Identifying non-UN Packaging

  • Approved packaging marking specifications not audited by staff accepting non-approved

& non-rated outer packaging

Identifying defective/ damaged/ leaking package Managing receivals Dealing with handling incidents

  • Mechanical handling incidents create damage or leakage  extra handling work and

isolating products

  • Overdrums or Segregation Packaging unavailable means direct waste management or

product return not possible

Responding to “in-transit” situations

Determining risk

How do you determine if the risk is:

  • Negligible, Low, Medium, High, Extreme
  • Acceptable or unacceptable to your company?
  • Controlled or mitigated?

29

slide-30
SLIDE 30

www.dmp.wa.gov.au/ResourcesSafety

Reviewing risk

What determines a review of your risk assessment?

  • New Dangerous Good for a consignor?
  • New packaging for Dangerous Goods?
  • New consignee location (new premises)
  • Incidents affecting container or vehicle integrity?
  • Incident that injured your employee?
  • Time?

30

Know your load

  • More than placarding!
  • Transport document and emergency procedure guide
  • Empty, full and

non-DG containers

  • Load plan

Understanding emergency response

  • Transport emergency response plan
  • Responsibilities under regulations
  • Credible scenarios

─ vehicle accident ─ vehicle rollover ─ transfer problem ─ leaking packages
