Abstract [en]

The European Commission had approved the Registration, Evaluation and Authorization of Chemicals (REACH) regulations in the year 2006, and will begin to implement it form 1 June 2007. This regulation greatly increases safety of protection for the users of chemicals, but it also brought a problem for the manufactures as well as downstream users. That is they have to generate and distribute much more Material Safety Data Sheets (MSDS) then before. This work is difficult for most companies since this job usually was done manually. The new regulation requires a much more efficient method to generate and distribute them.

This thesis project addresses the problem of automatically distributing MSDS and the corresponding metadata. It presents the underlying technology selected for this project. It gives a brief introduction of this project, the underlying technologies used, along with the methods used to deliver relevant and up to date materials safety information.

At last an HTTP web application approach was selected to solve the problem, the resulting application can efficiently notify a downstream user of the newly updated MSDS and transport the corresponding file and metadata. It is truly data driven, therefore the downstream user does not need to check for updates everyday, instead will be notified when there is an available update.

Abstract [sv]

Den Europeiska kommissionen antog 2006 en ny bestämmelse för informationsspridning av kemikalier, Registration, Evaluation, and Authorization of Chemicals (REACH), och den kommer att tas i bruk från första juni 2007. Bestämmelsen innebär ett starkt ökat skydd för användare av kemikalier, men den ställer även till problem för både tillverkare och användare. Exempelvis, de måste generera och distribuera betydligt fler materialsäkerhetsföreskrifter, Material Safety Data Sheets (MSDS), än tidigare. Detta arbete är krävande för de flesta företag eftersom arbetet ofta sker manuellt. Den nya bestämmelsen kräver mycket effektivare metoder att generera och distribuera MSDS.

Det här examensarbetet fokuserar på problemet att automatiskt distribuera MSDS och den korresponderande metadatat. Rapporten presenterar den underliggande teknologin för examensarbetet. Därutöver ges en kort introduktion till examensarbetet, den underliggande teknologin, tillsammans med de metoderna som används för att skicka relevanta och aktuella materialsäkerhetsföreskrifter.

Som avslutning väljs en HTTP Web applikationslösning för att lösa problemet. Den lösningen kan effektivt underrätta en användare att det finns en nyare MSDS och sedan skicka den korresponderande filen och dess metadata. Den är data driven, vilket gör att en användare inte måste kontrollera för uppdateringar varje dag, utan kommer att bli informerad när det finns en ny tillgänglig.
