Using a causation model when investigating HAZCHEM incidents

April 3, 2019

The primary reason for investigating any workplace incident is to understand why the incident happened and then introduce measures to prevent it from happening again. To get a better understanding of the causes of an incident, many WHS professionals use causation models during the investigation process. This blog takes a quick look at the evolution of causation models and offers a simple framework to apply to your next incident investigation (particularly if hazardous chemicals were involved.) The earliest incident causation models assumed that a series of events occur in a linear sequence, and this sequence is the ultimate cause of the incident. In this model each step in the sequence is dependent on the other (a bit like dominos falling) — so if you could eliminate any fault within the sequence, the incident could have be prevented.

Transporting biological and chemical materials - what you need to know

The landscape of biological and chemical logistics has changed rapidly - as have the regulatory frameworks around it. What has not necessarily kept pace is the end-user understanding of the nature of these logistical processes, their opportunities and their constraints. Twenty years ago, the transmission of biological and chemical materials was limited to a small range of organisations: usually national and international research companies, hospitals, major university departments, police and military departments with forensic responsibilities.

Setting record straight on testing harm in chemicals

The modern world is built on chemicals, be it the medicines we use, or cleaning fluids, crop protection products, or the raw materials for everything from laptops and mobile phones to clothes and furniture. Across all, we have created an entire modern society with chemicals, and, as a result, constantly stretched the size of the world population we can feed, clothe and shelter. Yet, balancing all the gains from the modern chemistry around us against any negative environmental and human impact has been a rising concern, making for ever greater focus on testing and on risk assessment.

Why chemical characterization is the best way to assess patient risk

Everyone is very familiar with the phrase when buying a house: All that really matters are three things - location, location, and location. This same principle applies to extractables and leachables chemistry analysis – the three things that truly matter are identification, identification, and identification. The greatest growth in the past ten years in demonstrating the safety of medical devices and container closure systems for drugs has been using analytical chemistry to determine what chemicals can leach from the device and what the patient is exposed to during its intended use.

How Chemical Companies Benefit from the Experience Economy

Article | February 10, 2020

To feel or experience from a business engagement started with customer experience mainly in the consumer products business. Today it has extended to even knowledge industries like the chemical industry where experiencing or feeling can be leveraged to include all stake holders from customers primarily to employees to supply chain people & suppliers and all else. With digital technologies this has become easier than before. The benefits from promoting the ‘feel’ or ‘experience’ emotion could be multifarious for the chemical industry as described in this article.
