Combustible dust explosions are a risk in many areas, but one of the most common locations is the dust collector. This white paper reviews OSHA and NFPA standards, how to identify hazards, and the types of equipment used for explosion protection. It also examines common shortfalls to compliance.
In dozens of industries and in millions of applications around the world, dangerous chemicals are transferred from their original shipping containers into smaller jugs or buckets or applied to other end-use processes. Historically, the predominant dispensing method in many of these applications has been through an open system where the liquid is poured out of the container. With a poured system, the container is often flipped on its side and the liquid is poured into a secondary container.
The user then just carries the bucket to wherever it needs to go. A mental image of this technique quickly reveals its potential dangers and inefficiencies.
The U.S. Occupational Safety and Health Administration’s Process Safety Management (PSM) Standard [29 CFR 1910.119(j)] require plant management to identify and address hazards. Further challenging plant management, the mechanical integrity (MI) element of the PSM has been difficult for many facilities to implement. In fact, PSM audits by OSHA have consistently demonstrated that MI accounts for a large number of citations at most facilities. In this Chemical Processing Special Report, we take a look at how to effectively implement strategies to comply with PSM standards including:
Common piping, hoses and valves hazards – what PHA (Process Handling Analysis) teams should look for to improve the quality of the hazard evaluation
MI element of PSM – an in-depth look at the stated MI requirements, the perceived interpretation of these requirements and further considerations for identifying your plant’s compliance strategy
MI implications – the impact MI has on plant’s written procedures, training, inspection & testing, and how equipment deficiencies and quality assurance programs are managed
Installing new production processes, or upgrading and expanding existing lines today may also require upgrading your air pollution control system. This white paper specifically focuses on the advantages of using a single direct fire thermal oxidizer and provides a case study example.
Determining the most economical option to control airborne emissions during chemical process operations presents several unique challenges. As with any add-on control system, the goal is to minimize the annualized total costs while maintaining proper operation. In this white paper, learn the different options that are available and which ones fit your process the best.
Environmental health and safety (EH&S) compliance programs for companies that house laboratories are complex and not easily maintained. Even the most basic plan involves keeping a variety of permits up-to-date, performing regular employee training, conducting inspections, complying with a myriad of chemical storage and handling requirements, and keeping a number of contingency plans current and complete. This white paper identifies the most common pitfalls and four simple steps to keeping your EH&S program current.
EPA tracks emissions of six principal air pollutants - carbon monoxide, lead, nitrogen oxides, particulate matter, sulfur dioxide, and volatile organic compounds. All have decreased significantly since passage of the Clean Air Act in 1970 - except for nitrogen oxides.
A large number of analytical and highly empirical correlations including monograms reflecting changing standards have been or are being proposed separately for gas and dust explosion relief venting. This white paper provides a generalized formula that is applicable to both gas and dust deflagrations including subsonic and sonic pressure relief conditions and is consistent with available experimental data and industry experience. Application of the model is illustrated for dust explosions. Download now.
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.

The dangers posed by combustible dusts are no longer being swept under the rug. Tougher regulations and greater corporate resolve are making dust hazard management an increasingly important topic for every manufacturing sector including the chemical, food and pharmaceutical industries.
This Special Report, brought to you by Chemical Processing details the dangers posed by combustible dusts and includes:
the latest thinking on both hazard identification and mitigation; it identifies how to mitigate dust hazards in oral solid dosage facilities; it takes an in-depth look at regulations and the thinking behind suppression technologies as a result of past activity; more!
Bristol-Myers Squibb manually monitored dissolved oxygen (DO) periodically and ran aeration blowers more than necessary to guard against variable loading rates. After upgrading the system to use online DO monitoring operators now have continuous DO readings in the aeration tanks, substantially reducing energy and maintenance costs.
All of the benefits of Product Lifecycle Management can be erased by significant non-compliance events that impact a company through fines, penalties, negative publicity, or prohibition to sell a new product in key markets. Without a sustainability strategy, the PLM value proposition is at risk.
This 8-page primer describes a method for identification of major acute risks in existing process facilities that can potentially affect on-site and off-site populations and for prioritization of mitigation methods.
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?
Gaseous oxygen measurement with amperometric sensors is the most direct and easiest solution for oxidation and explosion protection.
Unwelcome oxygen Tank blanketing is the process of filling the headspace in storage vessels and reactors with an inert gas to prevent its contents from exploding, degrading or polymerizing and to protect equipment from corrosion. A blanketing system is normally designed such that it operates under higher than atmospheric pressures, therefore preventing outside air from entering the vessel. As oxygen and moisture in the air can be undesired in numerous processes and applications, blanketing is done in a wide range of industries, varying from (petro)chemical to food and beverage, pharmaceutical to pure water.
OSHAs Hazard Communication Standard (HCS) is based on a simple conceptthat employees have both a need and a right to know the hazards and identities of the chemicals they are exposed to when working.
