The Australian standards for the safe storage and handling of flammable and combustible liquids (AS 1940:2017) have been revised, and the new standards were released on the 1st August 2017.
The myBMP Petrochemical Storage and Handling module is based on the AS 1940:2017 standards, and keeps cotton growers up to date with changes to the standards and legislation.
Some changes of interest to cotton growers:
- Polyethylene and composite tanks are now permitted for minor storage of combustible liquids. Compliant self-bunded polyethylene diesel tanks are now commercially available.
- The use of buried polyethylene liners in earthen bunds is now explicitly allowed, which may be a cost saver for remote diesel tank sites.
- Previously, a spill containment bund needed to be at least 100% of the largest tank plus firewater requirements; this has been changed to 110% of the largest tank or 25% of total stored in all tanks within the bund, whichever is greater. This simplifies the bund size calculation.
- The tank’s ‘safe fill’ level is to be no greater than 95% of the tank capacity. Each fuel tank should display a ‘safe fill’ limit signage.
