Viewpoints on Process Safety!

 

Our beliefs!

Safepark believes, that process safety is the art of working properly. Working properly means taking a scientific approach to solving your health, safety and environmental (HSE) challenges. Art is finding a common sense basis in your company culture to achieve the ultimate goal of process safety: That everyone are certain to return to loved ones at the end of a workday.

Our Experience!

Our involvement with process safety started with a major Canadian integrated oil company, where attitude to a safe work environment was tested already during the challenges presented to candidates during the first job interview. The attitude towards process safety was further targeted during involvement with laboratory safety in heavily experimental chemical engineering department.
We have extensive experience in introducing people to the Dow Chemical Exposure Index and the Dow Fire & Explosion Index. One day courses in either of these have been given many times.
For self-study we recommend the AIChE publications, whose fronts are shown here. However, if you are a student on a tight budget, then consider the guides and tools found on the website www.safety-s2s.eu under training. They are free.

Since the summer of 2008 Safepark has been part of a group encouraging developments in Multilevel Flow Modeling (MFM), which is a rule base technology for modelling industrial plants for reasoning about their states. Your can read more about MFM on mfm.safepark.dk. We have published papers about use of MFM during a HAZOP study and about MFM usage in alarm design and response to alarms.

Nogle sender falske faktura til danske kommuner i vort navn

Nogle misbruger vort domaine @safepark.dk til at sende falske faktura til danske kommuner.  Vi anbefaler på det kraftiste, at man deleter disse mail uden at klikke på den vedhæftede pdf fil. Vi er bekendt med, at mindst to danske kommuner har modtaget en sådan fake mail.

Denne type spam kaldes i internet jargon "Joe Job", og her er den bedste beskrivelse vi har fundet af problemet:
"They're using spoofed sender data to generate an email that looks like it's from your domain. It's about as easy as putting a fake return address on a piece of postal mail, so no, there's really no way to stop it. SPF (as suggested) can make it easier for other mail servers to identify email that actually comes from your domain and email that doesn't, but just like you can't stop me from putting your postal address as the return address on all the death threats I mail, you can't stop someone from putting your domain as the reply-to address on their spam."

Der er faktisk ifølge vor research af problemet ikke noget vi kan gøre, da de pågældende mail ikke kommer fra vort domaine eller en mailadresse, som vi har oprettet. Disse mails bruger alene en fake mail adresse som svar-til, og da vor mailservice hos Google fanger alle disse, så er det på den måde vi bliver opmærksom på problemet. En modtager af en sådan fake mail har endog ringet til os.

Her er hvad det anfales, at modtageren gør for at undgå sådanne mails kommer igennem til slutbrugere:

"To be more correct, you should say: No one's using your (domain's) server to send spam. Because they do use the domain, namely as the FROM-address. Of course SPF is no barrier at all, because the sender will use a hop-server which does not do SPF checks. Solution would be simple: The responsible Server for the TO-address should reject with 450 to the server the mail originates, not to send a DSN to the server which is responsible for the FROM-address"

Vi kan også anbefale at bruge Google's GMail, så slipper der ikke mange spam mails igennem til medarbejderen.
