Subject: Update asbestos contamination Eurogrit abrasive


Dear Customer / Business relation,

On 5 and 7 October 2017 we informed you about small quantities of chrysotile asbestos that have found its way into Eurogrit aluminium silicate blasting grit through the raw material (coal slag) supplied to us. Certain international customers received these statements one or a few days later.

We have received a lot of questions from customers about the exact levels of chrysotile found and the deliveries into which chrysotile may have found its way. It took longer than we had hoped before we could give you more information. We are keen on giving careful answers to these questions, and these issues required further investigation. In the past week Eurogrit also held numerous consultations with various Dutch experts in the field of asbestos and occupational hygiene, including as regards the correct analysis methods and any health risks that may have arisen. Several meetings were also held with the Dutch authorities. This contributed to the fact we could not inform you earlier.

Purpose of this letter

In this letter we provide you with more detailed information about the analyses that Eurogrit has had carried out so far (based on the method for analysis as agreed with the Dutch authorities ) on the raw materials delivered to Eurogrit and on the finished product Eurogrit blasting grit (aluminium silicate) that was present at the production facility in Dordrecht. We have also provided this information to the Dutch authorities. Counter-analyses are currently being carried out on behalf of the Dutch authorities.

Eurogrit blasting grit delivered from July 2017

  1. A small quantity of chrysotile was found in the coal slag raw material supplied to Eurogrit at the end of June 2017. Several samples were taken. The highest concentration measured in these samples is 57 mg per kg dry matter (57 mg/kg d.m.). We advised you to stop using all Eurogrit blasting grit that was manufactured with this raw material based on this analysis (see our first letter to you dated 5 October 2017).
  2. Eurogrit mixes several batches of the same raw material (from various suppliers) to make the finished product. The concentration measured in the blasting grit partly produced from the contaminated raw material that was supplied to us at the end of June 2017 ranges from 1.4 to 2.5 mg/kg d.m.

Eurogrit blasting grit delivered before July 2017

1.      Eurogrit also had samples analysed of coal slag raw material delivered to us between June 2016 and June 2017, insofar as sufficient material was still available. No or insufficient coal slag raw material from before June 2016 was available to carry out a proper asbestos analysis. The supplier or suppliers which Eurogrit currently suspects delivered the contaminated coal slag to Eurogrit at the end of June 2017 (and in July 2017) started delivering to Eurogrit in May 2015.

2.      In the coal slag raw material received by Eurogrit between June 2016 and June 2017, a concentration of chrysotile between 1.6 and 4.4 mg/kg d.m. was found.

3.      Eurogrit mixes several batches of the same raw material (from various suppliers) to make the finished product. No analyses results are available yet of the finished product Eurogrit blasting grit delivered to customers before July 2017. Based on the concentration of 1.6-4.4 mg/kg d.m. in the contaminated raw material from that period, our experts' current estimate is that the concentration of chrysotile in the blasting grit of before July 2017 is close to the detection limit.

4.      We have shared the data about the very low concentrations found in the raw material and the estimated consequences for the end product with the Dutch authorities. After consultation with the Dutch authorities it has been decided that for the moment in the Netherlands it is not necessary to take the same measures as those taken for the batches that were supplied as of July 2017.


Consequences of discovered levels for companies that have used the blasting grit

The chrysotile concentrations found may have an effect on the following:

-          the way in which unused Eurogrit blasting grit in closed packages may be disposed of;

-          the way in which unused Eurogrit blasting grit in opened packages may be disposed of;

-          the way in which used Eurogrit blasting grit may be cleaned up;

-          the way in which used Eurogrit blasting grit may be disposed of;

-          the question whether employees who have used Eurogrit blasting grit for blasting have been exposed to a higher concentration of asbestos than permitted by law;

-          etc.


Legislation in this field varies from one country to another. The only way to obtain more clarity on this is by consulting local experts. Unfortunately, Eurogrit is unable to advise you on this.

As soon as more information relevant to your company becomes available, Eurogrit will inform you as soon as possible. If you have an queries with regard to this letter, then please do not hesitate to contact us via e-mail at the dedicated account

Yours sincerely,

Met vriendelijke groet,
