Safety calculation software

Amsterdam, The Netherlands -Honeywell Safety Management Systems (HSMS) has released SafeCalc, a new software tool that was specially developed to perform reliability calculations for safety functions in accordance with IEC 61508.

New safety standards, such as IEC 61508 and ANSI/ISA S84.01, demand that safety functions realize a certain risk reduction, which is expressed as a Safety Integrity Level (SIL). If a safety integrity level for a specific safety function is defined, it is important to validate whether the proposed or implemented safety measure is sufficient to comply with the defined level. The new SafeCalc tool helps users carry out a quantitative analysis of the reliability (safety integrity) of the designed safety-instrumented functions. It can carry out complicated reliability calculations fast and accurately. The SafeCalc software is part of a complete safety consultancy package offered by HSMS.

A demo version of SafeCalc can be downloaded by visiting the HSMS Internet website .
