AS 1940 covers the storage and handling of flammable and combustible liquids, which includes diesel and oils.
Not every site is required to fully comply with AS 1940, nor is compliance mandated by the Work Health and Safety Regulation. However, your Environmental Authority, internal Standards, Environmental Management Plan or Procedures may dictate a requirement to comply fully, or in part with AS 1940. Furthermore, Section 357 of the Model WHS Regulation 2019 (if applicable to your site) requires spill containment systems where there is a risk of a spill/leak of a solid or liquid hazardous chemical.
AS 1940 is an extensive Standard, with a high level of compliance being rare on operational sites. However, there are a few aspects we commonly see as non-compliances, which sites are often not aware of, which we wanted to highlight.
Given the requirement for bunding to have a capacity to hold at least 100% of the largest container, the commonly observed situation of a permanently located IBC on a small (~30cm deep) bund, not undercover, is not compliant with AS 1940.
While not directly related to AS 1940, some of our other top priority items we check for relating to the management of oils and fuels:
