Free Site Survey And Correct Location Of Spill Kits Prevent Diesel Flowing Into A Storm Drain

A leading power generating company had requested a free site survey to assess their sites spill hazards and measures to ensure their site was fully compliant with legislation.

Carried out by our experienced NEBOSH qualified staff, we provided the customer with a detailed report on all areas of their site:

  • Identifying areas at risk
  • Recommending preventative measures
  • Recommending procedures for responding to incidents
  • Recommending appropriate equipment for prevention and response

Later, an incident occured whilst a forklift was being used to transport a mobile welding machine around the site. It fell from the forks and spilt diesel onto the road adjacent to the car park in close proximity to a storm drain. Owing to the fact that the free site survey had identified areas at risk and spill kits had been located in the identified areas the customer was able to quickly and effectively respond to the spill by:

Spill kit absorbent pads and booms were used to soak up and contain the spill

The drain cover from the spill kit was deployed to prevent any further diesel from entering the storm drain system

Pumps were switched off and pom poms (also supplied by Darcy) were deployed to soak up any final residue.

The oil interceptor was checked for any standing alarm.

The immediate availability of the spill kit contents contained the diesel spill and prevented any pollutants entering the storm drain and the interceptor thus reducing clean up and waste management costs.

BioCat Solves Uk Airport Fuel Spill Problems In Aircraft Standing Areas

Project Overview: Airport fuel spill clean up

Project Title: BioCat cleans up fuel spill in aircraft standing areas

Products/Services: BioCat hydrocarbon absorbent

Project Undertaken: July 2011

Industry Sector: Aviation

Overview

  • One of the UK’s top airports recently requested a demonstration of the BioCat Recycling Centres to deal with the issues of aircraft on the stands waiting for passengers leaking fuel during refuelling operations.
  • The problem is that when aircraft are turned around for return flights, time is imperative to avoid costly delays. One major issue is that there can often be fuel leaks when aircraft are being refuelled and this leads to the area being cordoned off to allow clean up to take place. If fuel is left on the stands, there is a danger of the contamination being spread across a larger area and thus causing safety issues.
  • The airport already uses Darcy absorbents and spill kits to deal with spills and wanted to make an improvement to their effectiveness.

Unit Features

BioCat is extremely cost effective as it will absorb all manner of spills but is especially effective on hydrocarbon based liquids.

Solutions and Savings

The demonstration took place on a windy day and due to the openness of the airfield, this would be a common environment. A small amount of oil was spilt on the stand and the BioCat applied to absorb and clean up the spill. The surface was relatively rough and the fine fibres of BioCat meant that the product was brushed in to all the cracks and uneven surfaces. The contaminated product was then shovelled in to the sieve and the unused product fell through to the hopper for reuse, while the contaminated clumps remained in the sieve for disposal as hazardous waste. A final washing of the area brought any residue of oil to the surface and a final application of the BioCat enabled the area to be reusable again. The airport are now considering BioCat recycling centres for other areas and have a system which is quick to use.

Products/Services: Spill response training

Project Undertaken: July 2011

Industry Sector: Manufacturing

Overview

Darcy’s client had an issue with its employees using emergency spill kits for everyday cleaning rather than for use in emergency situations.

Solutions and savings

  • We advised the client to undertake spill response training to provide the employees with full knowledge in which products to use in the event of an emergency spill.
  • We also advised the client that the use of tamper tags fitted to the spill kits would prevent the contents of kits being used for purposes other than which they are intended.
  • This has saved the company money on a monthly basis.

Need For A Streamlined And Cost Effective Ordering Method For Regular Absorbent Orders

Our customer, a provider of rail transportation to a population of over 15m, was very impressed with the quality and price of our absorbents. However, due to space limitations on site they could not order large volumes of absorbents in one go but wanted an easier way to manage ordering as he was placing orders every 3-4 weeks. As our prices were extremely competitive he also wanted to fix the pricing for a certain period of time.

Solution

We discussed setting up a call off order for a years worth of product based on his current usage. Owing to our customers commitment we duly fixed the price of the product for that length of time. They provided an order commitment to cover the quantity of pads as well as delivery costs for the length of the contract. Every few weeks the client sent in an email template to call off a quantity of absorbents at a time.

Benefit

The customer has retained competitive prices based on a years usage without having to take an entire years supply of absorbents in one go. He was extremely pleased with how the call off orders went as this has saved him a great deal of time in creating a new purchase order every few weeks. The customer is also benefiting from fixed pricing.
