You now need to put which hazard level the chemical is. OPeRA has 3 levels; 1-Low, 2-Medium, 3-High. You select a level depending on which H codes are associated with each chemical.
Firstly find the MSDS form for your chemicals, the supplier usually provides these, and OPeRA provides a link for each chemical in the order summary. Find the H codes and then determine which level of hazard your chemical is.
Click on the small edit button found to the far right of each chemical summary, on the summary tab.
This will open a box. In the middle of the box find the ‘Hazard Level’ section.
The default value is non-hazardous. Click the ‘select from all values’ text, which will open a drop down box, click the box and select a level. Pretty much everything has a hazard, so don’t select ‘Not Hazardous’ unless you are ordering unsharpened pencils etc…
Click the yellow ‘Save’ button.
