The library works like building blocks made of vector arms, legs, and emotions. You can mix these elements to create different Peeps.
You can use Open Peeps in product illustration, marketing imagery, comics, product states, user flows, personas, storyboarding, invitations for your quinceañera...or anything else not on this list.
The library is in the public domain under the CC0 License. This means you can copy, modify, distribute, remix, burn, and use the work, even for commercial purposes, without asking permission.
EEMUA 158 provides a comprehensive guide for ensuring the safe operation of safety instrumented systems in process plants. By following the guidelines and recommendations outlined in the guide, organizations can ensure that their SIS are designed, implemented, and maintained to achieve the required level of safety. By adopting best practices and implementing EEMUA 158 effectively, organizations can minimize the risk of hazardous events and protect people, the environment, and assets.
The relevance of EEMUA 158 is highlighted by industrial disasters. The 2005 Buncefield fire in the UK, while caused by an overflow, exposed significant gaps in tank farm inspection regimes. Post-incident reports recommended stricter adherence to standards like EEMUA 158 regarding overfill protection and corrosion monitoring. Similarly, countless smaller spills of diesel or caustic soda into groundwater have resulted from pin-hole leaks in tank bottoms—precisely the type of defect that EEMUA 158’s acoustic emission testing and floor scanning protocols are designed to catch.
EEMUA 158 is more than a document; it is a commitment to vigilance. In an era of aging industrial infrastructure—where many storage tanks built in the 1960s and 1970s are still in service—this standard provides the intellectual tools to extend asset life safely. It recognizes that a tank’s enemy is not just time, but entropy; and entropy can be managed through intelligence, data, and proactive intervention. For the engineer walking the catwalk of a 50-year-old tank, EEMUA 158 is the unseen guardian, whispering the critical questions: Where will the next leak start? How fast will it grow? And when must you act? By answering these questions systematically, EEMUA 158 ensures that these silent steel giants remain safe, efficient, and reliable guardians of the world’s liquid energy and chemical resources.
The standard is famous for its practical "repair priority" tables. It distinguishes between:
Unlike design codes that are often written by manufacturers, EEMUA 158 was created by users —the companies that own and operate the tanks. First published in 1995 and regularly updated (most recently Edition 5 in 2021), it addresses a critical gap: what happens after the tank is built and commissioned? While a tank might be structurally sound on day one, decades of exposure to corrosive products, atmospheric conditions, and thermal cycling degrade its integrity. EEMUA 158 provides a structured methodology to detect, evaluate, and mitigate these threats before they result in catastrophic failure, environmental disaster, or financial loss.
EEMUA 158 provides several recommendations for SIS design and operation, including:
