In this paper, an uncertainty assessment analysis extension is proposed for the inoperability input-output model (IIM), which is a methodology for assessing the propagated consequences of initial disruptions to a set of sectors. The IIM has been developed to help understand infrastructure interdependencies on deliberate external attacks or unfortunate natural disasters. Since the final demand perturbation may be affected by the psychological impact on consumers. In this paper, the uncertainty demand-driven IIM is extended to allow final demand perturbations in the form of lognormal probability distributions. The Monte Carlo simulation is used to demonstrate the uncertainty analysis methodology in detail through a four-sector economy system, and the results show that the value of interdependency analysis in the risk assessment process as an integral part of interdependent infrastructure.

Combatting bacteria growth in emergency tank showers
Emergency safety showers and eye wash stations are essential for sites where workers could come into contact with hazardous chemicals. In some environments providing this life saving equipment can be challenging, for instance a consistent supply of potable water cannot be guaranteed, or a tepid temperature can be difficult to maintain due to extreme ambient temperatures. In these instances, emergency tank showers provide a viable solution. However, because emergency tank showers can go unused for extended...
EUON Study Finds Knowledge Gaps Exist in Risk Assessment of Nano-Sized Pigments
The European Union (EU) Observatory for Nanomaterials (EUON) announced on September 7, 2018, that a new study found gaps in the current knowledge on the hazard and risk assessment of nano-sized pigments. The study, commissioned by EUON, identified 81 nano-sized pigments currently used in the EU market. The study was done to collect publicly available information on the identified nano-sized pigments that are on the EU market. EUON states that the findings “show that the risks of nanopigments cannot...
The Need for an Expanded Role of Risk Management in Healthcare
The role of risk management in healthcare has come a long way over the years. But as risks to the healthcare industry multiply—both in number and costs—risk management and risk managers need to be at the forefront of the business. If not, healthcare organizations can’t thrive, or potentially even survive. How healthcare risk management has evolved Today’s healthcare organizations face challenges like the rapid advancement of technology, financial risk, evolving patient safety regulations...
7 Signs You Should Seriously Take an ‘EQMS Way’ of Managing Your Training Requirements
Employee training has always been a vital component of a company’s quality culture and actually solidifies it but in certain scenarios EQMS is the best choice to effectively manage the trainings in an organization. With the added benefits of interoperability with standard documents (such as SOPs/WIs/Guidelines, etc.), CAPA, Risk Assessment etc. an EQMS way of managing trainings is becoming a trend nowadays. The following 7 signs are in no particular order. You have to read them and decide which ones are...
General Information Neonicotinoids are a family of active substances which include imidacloprid, acetamiprid, thiacloprid, dinotefuran, nitenpyram, thiamethoxam and clothianidin. They are used in plant protection to control harmful insects and also in veterinary medicine. The name literally means “new nicotine-like insecticide” due to the chemical similarity to nicotine. Sometimes the name neonicotinoids is shortened to “neonics” or “NNIs”.¨ The neonicotinoid class...
