Safety Size Tips and Helpful Hints

Start a gas/vapor filled vessel fire sizing as a ‘Calculate Area / Gas Area’ calculation (if capacity is unknown).
Start a liquid filled vessel fire sizing as a ‘Calculate Area / Liquid Area’ calculation (if capacity is unknown).
If fire sizing capacity is provided by end user/customer, there is no need to perform the fired-vessel capacity calculation. Start the sizing as a gas area sizing.
SafetySize is not a configurator. The program will allow for erroneous material combinations and valve ‘configurations’ to be selected.
Always use the end-users process data when available. Do not use process data built into the program over a customer’s given data.
Ask your customer if they prefer to see API or ASME areas.
Always click on the “Display Model Parameters” button, so that all information will appear on the datasheet.
SafetySize report print previews can be copied into “Microsoft Word” and modified.
For 2-phase separated flow method, there is no calculation sheet. Additional gas and liquid calculations must be run to get the calculations sheets.
Do not use “calculate flow” calc. types for multiple valve sizing.
The program does not allow you to perform pressure and vacuum calculations at the same time.
If a fluid property for a fluid that exists in the program database is changed from the default value, add a period (.) to the end of the fluid name, so that the changed property will be saved.
