Why Process Safety Management Audits Fail
Most companies have completed at least three process safety management(PSM) compliance audits of their covered facilities since the promulgation of the OSHA PSM standard. These companies, however, are not seeing noticeable improvements in their PSM programs. In fact, many companies feel that their PSM programs have become less effective. What has happened and why? Are there any lessons learned from the Enron collapse and its auditing program? What needs to be done?
Whitepaper: On-Line Instrumentation Helps Lower DAF System Costs
Many industrial plants use dissolved air flotation to remove fats, oils and grease, and suspended solids from wastewater. Chemical additions are often kept higher than necessary to account for variations in influent water quality that are characteristic of industrial facilities. Continuous monitor
White Paper: Understanding the Risks Associated with FIBCs and Electrostatic Hazards
Flexible Intermediate Bulk Containers (FIBCs) have found their niche in the worldwide transportation of powdered, flaked and granulated products. FIBCs are typically made of woven plastic with some type of liner insert and are often referred to as super sacks, big bags or bulk bags in industry. During filling and emptying of FIBCs there is a steady accumulation of static charge that can result in electrostatic discharges from the FIBC. This may in turn provide sufficient energy for ignition of combustible particulate solids or flammable vapors, not to mention unsettling shocks to nearby personnel. In this white paper we review the NFPA 654 Standard for the Prevention of Fire and Dust Explosions from Combustible Particulate Solids and the importance of why identifying the Minimum Ignition Energy (MIE) of your combustible dust or flammable vapor is a necessary component for selecting the correct FIBC Type for your application.

White Paper: Helping Business Users Understand and Measure Data Quality
Many companies have invested heavily in mission-critical business software initiatives. Much time and effort has gone into deploying sophisticated customer relationship management solutions, adaptive supply chain software, ambitious data migration projects, and other endeavors. All too often, however, these worthy but expensive initiatives fail to deliver anticipated benefits because theyre hobbled by poor data. Download this white paper to learn how to understand and measure your business data for successful application.
What is a Bearing Isolator?
A bearing isolator is a non-contact, non-wearing, permenant bearing protection device. Read about they can be effectively used in your plant.
What Does It Cost To Own Your Dust Collector Filters?
When choosing filters for your cartridge dust collector, a Total Cost of Ownership (TCO) calculation allows you to make the most economical and sustainable choice. TCO is a step-by-step evaluation that explores energy use, maintenance and other factors to compare the real costs of operating a dust collector with different filters. This white paper explains how to perform TCO calculations to save money, time and energy.
Using Operator Interfaces to Optimize Performance of Industrial Wireless Networks
The performance of wireless networks can change over time due to increased performance demands, changes in the radio frequency (RF) environment and changes in the physical environment. This article will explore the use of a wireless diagnostic OLE for Process Control (OPC) server technology to embed diagnostic information in human machine interfaces (HMIs), thus optimizing industrial wireless network performance.

Use CFD to Improve Crystallization | Chemical Processing
In this article, Kumar Dhanasekharan, Ph.D., technical specialist with the computational fluid dynamics (CFD) specialist Fluent, Inc., shows how modelling crystallizers using CFD can help improve process understanding, control crystal size distribution (CSD) and improve pharmaceutical crystallization results.
Understanding Regulated Health and Safety Standards--Part 1
This paper provides the viewpoint of the American Conference of Governmental Industrial Hygienists (ACGIH), a private not-for-profit, non-governmental corporation open to all industrial hygienists or other occupational health and safety professionals. The authors have the opinion that there are misunderstandings about the use of regulated health and safety standards.
In part one of this article, they provide some information on how regulations are formed and advice on using these values to conduct business. Employers and employees need this fundamental understanding to make informed health and safety decisions. This information is also useful for guiding public decisions about everyday toxic exposures.
The unfortunate propensity of dust explosions to destroy entire facilities and claim lives is very real. Powder handling processes often are comprised of interconnected enclosures and equipment. Flame and pressure resulting from a dust explosion can therefore propagate through piping, across galleries, and reach other pieces of equipment or enclosures, leading to extensive damage. In this Chemical Processing Special Report, we take a look at the latest NFPA standards and dust explosion mitigation strategies. This Special Report covers:
Significant revisions to dust explosion standards – NFPA 654 major changes include new administrative requirements
How to defuse dust dangers - carefully consider and then counter risks of fire and explosion
Five common dust explosion misconceptions that can lead to a false sense of security
Prepare your facility against potential dust explosion dangers. Download your copy of this Chemical Processing Special Report now.
