S-Risk offline for 1.0.9 update

Coming Monday, February 24th, we will be updating S-Risk to version 1.0.9. Server downtime can be expected between 8 and 9h30, please take this in to account when planning simulation work.

S-Risk offline coming Thursday

Coming Thursday, S-Risk will be unavailable in the morning for an update to our network configuration. Some downtime can be expected from 8am on.

Server offline for updates

Later today, the S-Risk server will be offline for a short while to apply necessary operating system updates. Some downtime can be expected at 5pm.

S-Risk helpdesk availability

We would like to inform you that the S-Risk helpdesk will be unavailable between Christmas and New Year. Incoming questions will be answered as soon as possible afterwards.

S-Risk Training session

Given sufficient interest, an S-Risk training session will be organised in January. More details can be found on the Events page, please express your interest via info@s-risk.be or via our Contact form.

S-Risk updated to 1.0.8

S-Risk has been updated to version 1.0.8. For an overview of the changes in this release, see our Release Notes page.

S-Risk 1.0.8

Released on October 22nd, 2013.

List of changes in this release

S-Risk 1.0.8 is a bugfix release, adjusting the loading of chemicals in the S-Risk calculation model. This was a potential source of errors when additional chemicals were added after a first calculation.

Licensees with simulations potentially affected by this problem have been informed earlier. It is sufficient to re-run the calculations for the affected simulations to generate a new report with correct results.

Planned software update

On Tuesday October 22nd, the S-Risk web application will be unavailable between 08h00 and 09h30 for a necessary software update. An e-mail will be sent afterwards.

S-Risk updated to 1.0.7

S-Risk has been updated to version 1.0.7. For an overview of the changes in this release, see our Release Notes page.

S-Risk 1.0.7

Released on October 21st, 2013.

List of changes in this release

  • Risk tab:
    • S-Risk required valid risk threshold values for ALL routes of an enabled local effect type, which are not always available. This is now more flexible: for local effects, S-Risk now allows risk threshold for individual routes to be left empty.
    • edit fields in the Risk tab are now more clearly indicated to avoid confusion
  • Simulation names are not allowed to have special characters anymore, as this causes problems for downloading report files.
  • Bugfix in calculations when drinking water supply pipe material = "Other"
  • Benzo(g,h,i)perylene data for background exposure via food have been adjusted.

Background & implications of these changes

These are mostly interface-related changes, not affecting simulation results in any way.

Only the changes for benzo(g,h,i)perylene need special attention. This concerns changes in the values for background exposure via food. These values changed from NO background exposure (0 mg/kg.day for all age categories) to following values listed hereafter. The impact is minimal as background exposure is negligible compared to the oral TDI of 3E-2 mg/kg.d:
