• Who is being assessed?

Stage 1: Work Preparation and Planning

• It is a normal working day on site, the weather is dry and personnel can be seen in the substation adjacent to a transformer that is making an unusual and excessive buzzing noise, considering the potential for an environmental incident, what precautionary measures should be taken?

• Key actions and expected responses:
  
  • Work preparation and planning
  • Spill kits in vans (clay mats, pads, mini booms)
  • Environmental risk assessment completed
  • Complete dynamic risk assessment has been completed for activities
  • SLAM process has been applied before starting work

Stage 2: Disruptive Failure

• The transformer fails completely, resulting in disruptive failure as a loss of 20,000 litres of oil is ejected from the system and begins moving throughout facility, what reactionary measures should be taken?

• Key actions and responses to expect:
  
  • Contain leaking asset by isolating the spill (eg. tripping the separator and/or bunging sump)
  • Deploy spill kit to protect surrounding drains with particular focus on those down gradient from the spill (press clay mats onto the drain to seal it and/or place absorbent booms around and secured within drain)
  • Stopping vehicle and pedestrian movements through oily area
  • H&S considerations
  • Communication with relevant Senior Authorised Persons/Line Manager/Team Leaders of Incident
  • Aquiring site Pollution Incident Response Plan (PIRP)
  • Considerations for vulnerability of receptors and potential pathways

Stage 3: Post Incident Management

• The leak from the transformer has been stopped and is no longer flowing freely, considering the significant amount of oil lost that is now stagnant on the ground, what would the next steps be in dealing with the incident?

• Key actions and responses to expect:
  
  • Empty leaking asset using oil van or pump into tanks
  • Find drainage plans in control room
  • consideration of pathway and receptors
  • Consideration of the type of drainage on site (i.e., does the site drainage have an oil/water separator)
  • Checking the drains to see if oil has entered them
  • Contacting our Emergency Response Contractor

Stage 4: Preventative Measure Failure

• It is confirmed that oil has been discharged from the site due to the drains receiving the oil either not having an oil water separator in place or complete failure of oil water separators, what are the immediate key actions and considerations to take on first hearing this information?

• Key actions and responses to expect:
  
  • Contacting RSK for on and offsite management
  • Checking condition of oil water separator
  • Contacting Licence Environmental Specialist or Advisor
  • Clean up oil from the yard (RSK)
  • Drainage and oil water separator cleaned out if needed
  • Reporting the incident to the regulator
  • Reporting the incident via OneHS (Team Leader)

Stage 1: Work Preparation and Planning

• It is a normal working day on site, the weather is dry, and a tanker is emptying 10,000 litres of dirty oil into tanks then refilling with clean oil, considering the potential for an environmental incident, what precautionary actions should be taken?

• Key actions and responses to expect:
  
  • Work preparation and planning
  • Checking the oil van can hold volume required
  • Checking hoses and other equipment is fit for use by visual checks and ensuring it is tagged as fit for use within the dates provided
  • Complete dynamic Risk Assessment has been completed for the activity
  • SLAM process has been applied before starting work
  

Stage 2: Disruptive Failure

• The shut off valve from the dirty waste oil to the tanker has failed completely and overflowed from the topfill, a loss of 300 litres of oil spills onto the concrete floor in front of the storage tanks, what reactionary measures should be taken to manage the incident?

• Key actions and responses to expect:
  
  • Stop the leak at source by closing valves on tank and oil van tanks
  • Deployment of spill kit around drains
  • Consideration of other materials available
  • Taking steps to stop vehicle and pedestrian movements through area
  • H&S Considerations
  • Communication of incident to relevant Senior Authorised Persons/Team Leader/Line Manager
  • Get site Pollution Incident Prevention Plan (PIRP)
  • Repositioning of vehicle(s) to an area protected by an interceptor or to remove/reduce risk of contact with vulnerable receptors
  • Emptying leaking assets using oil van or pumping into tanks
  

Stage 3: Post Incident Management

• The leak from the shut off valve failure has been stopped and is no longer flowing freely, considering the significant amount of oil lost to the drains and stagnant oil in the yard, what would the next steps be in dealing with the incident?

• Key actions and responses to expect:
  
  • Handover incident to TL/Env specialist to be able to manage the long term clean up
  • If possible to do so take photos (for handover, records and lessons learnt)
  • Stop the leak at source
  • Close valves on tank and oil van tanks
  • Deployment of spill kit around edge of spill and drains
  • Consideration of other materials available
  • Taking steps to stop vehicle and pedestrian movements through oily area
  • H&S considerations
  • Communication of incident to relevant Persons/Senior Authorised Persons/Line Manager,
  • Get site Pollution Incident Prevention Plan (PIRP)
  • Repositioning of vehicle(s) to an area protected by interceptor or to remove risk of contact with vulnerable receptors
  • protecting asset with spill materials
  • emptying leaking assets using oil van or pumping into tanks

Stage 4: Preventative Measure Failure

• It is confirmed that oil has been discharged from the site due to the drains receiving the oil either not having an oil water separator in place or complete failure of oil water separators, what are the immediate key actions and considerations to take on first hearing this information?

• Key actions and responses to expect:
  
  • Contacting RSK for on and offsite management
  • Checking condition of oil water separator, tripping/isolating it if faulty
  • Contacting Licence Environmental Specialist or Advisor
  • Clean up oil from the yard (RSK)
  • Drainage and oil water separator cleaned out if needed
  • Reporting the incident to the regulator (RSK)
  • Reporting the incident via OneHS (Team Leader)
