TRICHLOROETHYLENE – FACT OR FICTION?

Recently various views on the legislation regarding this solvent have been expressed by a number of organisations. Some of these views are not necessarily accurate leading to confusion for many people, and it is hoped that the following essential details will be helpful to readers of IMFormation.

Trichloroethylene as a vapour degreasing solvent
The following guidance has been agreed by a committee consisting of the Surface Engineering Association, Engineering Employers Federation in association with the Government Environment and Health & Safety bodies. Whilst controls on the use of Trichloroethylene (often known as ‘Trike’ or TCE) have been in place for many years, more stringent controls were introduced from 31 October 2007 and are now in place.

Environmental Legislation
Restrictions on emissions from degreasing tanks have been introduced under the EU Solvent Emissions Directive (SED). In England and Wales, SED is enforced by Local Authority Inspectors and for larger users, by the Environment Agency. In Scotland, SED is enforced by the Scottish Protection Agency (SEPA). SED takes effect at two levels:
  • Lower risk solvents require regulation if consumption exceeds 2 tonnes/year
  • Higher risk solvents (known as ‘designated risk phrase materials’) requires local authority PPC regulation if consumption exceeds 1 tonne per year.
Higher risk solvents are those designated as:
  • Ahalogenated volatile organic compound (VOC) which is assigned or needs to carry the risk phrase R40
  • A substance which is a VOC and which is assigned or needs to carry one or more of the risk phrases R45 , R46, R49, R60 or R61 and
  • A preparation which, because it contains substances that are VOCs, is assigned or needs to carry one or more of the risk phrases R45, R46, R40, R60 or R61
Consequently, TCE (which has the risk phrase R45) is classed as a higher risk solvent. If SED applies, the user has to substitute higher risk solvents in the ‘shortest possible time’ (see Defra Guidance Note AQ 9(04).

Other European Health and Safety Legislation affecting TCE
TCE is a priority Substance for consideration under the European Union’s Existing substances Regulation (EC793/93). Following negotiations, a voluntary agreement (“Charter for the safe use of TCE in metal cleaning “) has been signed by all European producers of TCE with the commitment that:
  • TCE will not be supplied for metal cleaning/degreasing after 2010 unless the user has a closed system (defined in terms of specific types of equipment reference to standard EN 12921 part4 “Safety of machines using halogenated solvents”);
  • User companies must give a written undertaking (by 31 Dec 2010) that TCE will be used only and exclusively in closed systems as defined above;
  • The full co-operation of EU distributors of TCE in the agreement will be secured; and
  • Signatures will fully document the commitments made by suppliers, distributors and users, monitor the progress of the voluntary agreement and report annually to the Commission and Member States.
What is the practical effect of the above?
1. If a degreaser consumes more that 1 tonne of solvent per year it must have a PPC permit from the relevant authority or in Scotland from SEPA by 31 October 2007 and will normally be expected to have replaced any TCE used by that date.
In practice, it is expected that a company will need enclosed degreasing machines in order to comply, but it is nevertheless envisaged that a few open-topped machines may be compliant, depending on their size, utilisation and the nature of the degreasing work

2. The European supplier’s Charter means that, from 1 January 2011 all existing open- topped vapour degreasing machines using TCE will need to be totally enclosed, even where the solvent consumption is below 1 tonne per year, and not caught by the PPC legislation. Engineering companies using open-topped degreasers are looking for alternative to TCE. These should preferably include other lower risk organic solvents or aqueous degreasing methods.

Thanks are expressed to SEA for permission to circulate the essential details from the articles published in Watchword.

Health, Safety and Environment

Nickel Guidance Symposium receives congratulations from across the ‘pond’
Congratulations received from Dr Adriana Oller of NiPERA laboratories in North Carolina who quotes ‘I think you should be congratulated since the current urinary results demonstrates quite significant reductions in overall exposures. From NiPERA’s point of view we encourage you to continue this program of regular sampling as a way of assuring controlled exposures and detecting any possible control problems if they were to arise’. Well done to John Healy and colleagues.

Company News and Products

Scott Bader
A new anti-corrosion primer with heat resistant properties has been introduced by Scott-Bader. Called Texicryl 13-600, it is a styrene copolymer, phenol ethoylate free, and possibly the first waterbased primer of this type to achieve 500 hour salt spray resistance on a 50 micron single dry film thickness. Texicryl is also resistant to discolouring in high humidity conditions, and can withstand higher temperatures than some other chemistries. It has high blister resistance to fuels, brake fluids and coolants and is particularly suited for automotive applications.

Companies Beware ??? Latest Scam
Thanks to Andrew Swain of Anopol we can draw your attention to a possible scam or at least to unethical selling technique, usually a phone call to the maintenance engineer – ‘I am ringing to thank you for taking part in our survey and to show our appreciation we would like to send you a drum of our new environmentally friendly degreasing agent’ or some other similar words.
The person contacted will most likely assume that someone else in the company had been contacted. When requested for an order number, asks why, and is told that they have had materials refused because of no order number or quoted as verbal.
Material arrives, and much later an invoice but for a much larger quantity than that delivered and being charged for. The name of the company has not been tracked other than it appears that the company name contains the word ‘chemical – Is this a Scam?
The above is only a abstract of the document produced by Andrew who would be interested in hearing from others who may have had similar experience Tel: 0121 632 6888

REACH Tin Metal Consortium
Membership of this consortium continues to grow as companies are working together in order to minimise the costs and resource requirements of dealing with the complex requirements of REACH, and the number of members has been increasing since the group was formed in October. Membership is open to any company.
ITRI is acting as the Secretariat of the consortium, and runs the technical programme, managing the administration of the group.
Companies who are interested in joining the REACH consortium for tin metal or discussing the activity of inorganic tin chemical compounds, should contact Kay Nimmo – Tel: ++44 (0) 1727 871 312 or by email at: kay.nimmo@itri.co.uk

IMF News

REACH ‘Club’
Delegates who attended the REACH symposium on 9 October 2007 will remember the discussion on the possibility of IMF setting up a ‘Club’ similar to the one set up on IPPC by the SEA some time ago. As a result, an initial meeting was held at Exeter House in mid December which attracted a good cross section of members and a general consensus of opinion that it would very helpful for members/member companies in attempting to wade through the vast amount of paper work available.
A second meeting was held on 7 January and it was agreed by all that the meetings were going to be of great benefit, as the impacts of the legislation were different from end users and supply house perspective and each will learn from each other. Many points were raised during the meeting which it is hoped can be addressed for discussion at the next meeting.
There is no cost for attendance at what will be monthly meetings at Exeter House (even the supply of a buffet lunch) Interested ? – Next meeting Thursday 7 February. Contact Ken Hoare at Exeter House Tel: 0121 622 7387 or email the IMF on: Exeterhouse@instituteofmetalfinishing.org
