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

Safe design has long been a priority in the process industries. A safe design basis, together with a formal safety management system and safety practices, procedures, and training, is critical for providing that level of confidence required for risk management. The goal of process safety management is to consistently reduce risk to a level that can be tolerated by all concerned. A systematic, risk-based approach to safety design can help eliminate hazards that pose intolerable risk from the process and mitigate the potential consequences of hazards.
Given the amount of effort companies put into process safety management programs, it is important not only that they comply with regulations but that they are truly effective as well. This paper highspots points to check.
This new U. S. Occupational Safety and Health Administration paper describes OHSA's confined-space satndard, and discusses how to meet it by controlling hazards, administering entry permits and assigning duties, as well as how to deal with emergencies and OSHA assistance available.
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.
For years the industry has been talking green. But what real strides have been made? Will a Presidential Executive Order compel the industry to speed up efforts to actually go green? While pollution prevention was the original goal of green chemistry, todays efforts promise to have a substantial economic impact. This Special Report will bring you up to speed on fruitful efforts to go green including an update on the growing interest in bio-based feedstocks.
In chemicals processing, significant hazards exist -- such as those from fire, explosions or toxic release. The processes themselves, the chemicals being processed and the procedures followed, or lack thereof, can all contribute to the risk exposure of these hazards. What can processors do to mitigate these risks? For chemicals processors, it's crucial to implement processes and solutions to detect and prevent these hazards from occurring in the first place.
Chemical Processing has taken an in-depth look at plant safety -- how to identify the hazards and implement processes and procedures to ensure a safer working environment. This comprehensive Chemical Processing Special Report titled: Improve Plant Safety is now available to download for free.

Increasingly stringent clean air standards and heightened concerns over greenhouse gas emissions are driving technology enhancements in the chemical processing industry. This white paper explains some of the abatement challenges this industry faces and demonstrates how many chemical processors are integrating newer, more efficient emission control technologies for the destruction of Volatile Organic Compounds (VOCs) and Hazardous Air Pollutants (HAPs).
The paper also includes a case study, demonstrating how one Pure Terephthalic Acid (PTA) plant saved nearly one million dollars by upgrading to a newer thermal oxidizer technology.
In September 1998 the EPA promulgated a ruling in 40 CFR, imposing strict new standards to reduce emissions of toxic air pollutants from the manufacture of pharmaceutical products, including prescription and over-the-counter drugs. The agencys rule was intended to reduce emissions of a number of air toxics and hazardous air pollutants (HAPs), including methylene chloride, methanol, toluene and HCI. It was estimated at the time that the ruling would reduce air toxins annually by approximately 24,000 tons or 65 percent from contemporaneous levels. The affected pharmaceutical manufacturing processes included chemical synthesis (drawing a drugs active ingredient) and chemical formulation (producing a drug in its final form).
Chemical, petrochemical, and oil-reﬁning plants are process-intensive operations with regulatory requirements to protect the surrounding water and air from the effects of industrial pollution.
