NOISE ENGINEERING DESIGN

When hearing protection and administrative controls cannot be employed to reduce noise exposures, EI’s engineering team assists our industrial clients in the identification and design of noise engineering controls.  Engineering controls for excessive noise can be developed for isolated pieces of manufacturing equipment or entire industrial process lines. Initial steps require performing sounds level facility surveys and personnel noise dosimeter monitoring of manufacturing personnel by experienced industrial hygienists. Noise monitoring results are utilized to determine specific sources of excessive noise, as well as the mechanism of sound generation/propagation emitted by the excessive noise source.  Multiple sources of noise will subsequently be “rank ordered”, which will allow for a range of possible engineering controls, typically addressing the loudest sound sources first.  EI’s professionals segregate excessive noise sources into two distinct classes, vibrational noise and noise turbulence.

Once all specific noise sources are identified, EI utilizes the following logical approach to determine the optimal systems to reduce/control excessive noise:

  1. Substitution of equipment (fundamental first step)
  2. Categorization of source into vibrational noise and turbulence-based noise
  3. Reduction of driving forces which cause excessive noise
    a. Decreasing machine speed
    b. Maintaining dynamic balance
    c. Provide vibrational isolation
    d. Increasing impact duration, while reducing the force of impact
  4. Reduce response of vibrating surfaces
  5. Reduce area of vibrating surfaces
  6. Reorienting directional noise sources
  7. Reduction in velocity of fluid flow (air ejection systems, valves, vents and piping)
  8. Provide sound absorption alternatives
  9. Design and installation of equipment and personnel noise enclosures

Let EI’s team of industrial hygienists and engineers work collaboratively to identify and provide cost-effective engineering solutions aimed at reducing exposure of your workforce to excessive noise.

Climate Action in Financial Institutions Initiative: Inspiration for the PCAF Global Accounting and Reporting

Welcome back to our Banks, Borrowers, and Climate Change series! In case you missed our introduction to the series, you can read it here. Our first blog in the series, “Banks, Borrowers and Climate Change: How Disclosure of GHG Emissions Will Impact the Lending Process for Publicly Traded Corporations” is also available. The bottom line: The SEC will require public companies, including banks, to disclose annual carbon emissions from their operations in their annual report.

NFL Green Touchdown: Sustainability Highlights at the 2024 Super Bowl

NFL Green Touchdown: Sustainability Highlights at the 2024 Super Bowl

In the highly anticipated 2024 Super Bowl between the San Francisco 49ers and the Kansas City Chiefs, the National Football League (NFL) is not only showcasing top-tier athletic talent but is also making a significant impact through its sustainable initiative, “NFL Green.” As the world turns its attention to the game, let’s delve into the specific efforts and innovations that mark this year’s Super Bowl as a milestone in environmentally conscious sporting events.

Banks, Borrowers and Climate Change: How Disclosure of GHG Emissions Will Impact the Lending Process for Publicly Traded Corporations

The EI Group, in collaboration with Environmental Risk Innovations (ERI), recently launched a joint blog series which outlines the impact of the SEC’s proposed climate disclosure rule, which will require all publicly traded corporations, including banks, to disclose their direct and indirect GHG emissions. For manufacturers, carbon emissions are generally those resulting from the products they produce (direct), from the production of energy used in their production process (indirect) and their supply chain (indirect). For publicly traded banks, this concept is slightly more abstract.

The SEC Targets Financed Emissions: Banks, Borrowers and Climate Change

As climate change becomes an increasing risk to financial stability—whether by natural disasters such as hurricanes, rising sea levels and wildfires, or to corporations from increased costs associated with transition to a lower-carbon economy—financial institutions are exploring ways to integrate this segment of risk management into their operations. This initiative is being driven by a standardized climate disclosure rule anticipated for release by the Securities and Exchange Commission (SEC) in early 2024.

The Newly Regulated NFPA 70B: What Does It Mean and What Does It Cover?

The Newly Regulated NFPA 70B: What Does It Mean and What Does It Cover?

Unplanned downtime, equipment failures and safety hazards brought on by the electrical infrastructure that was installed as a “run to fail” system can have severe consequences. To address these concerns, the National Fire Protection Association (NFPA) has developed the NFPA 70B. This set of guidelines provides a framework for establishing and maintaining an effective electrical preventive maintenance (EPM) program. The NFPA 70B transitioned from a recommended practice to a standard as of January 2023. Understanding that a standard has language such as “shall” means that the Authority Having Jurisdiction (AHJ) can use the 70B as an enforceable code.

What is the European Union CLP and How Does it Impact Your Business as a Chemical Exporter in the US?

What is the European Union CLP and How Does it Impact Your Business as a Chemical Exporter in the US?

The European Union (EU) CLP (Classification, Labelling, and Packaging) Regulation falls under the broader framework of chemical regulation in the European Union. The primary legal basis for the CLP Regulation is Regulation (EC) No 1272/2008.

This regulation, more commonly referred to as the CLP Regulation, aims to align the EU system for the classification, labeling, and packaging of substances and mixtures with the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). The GHS is a globally recognized system developed by the United Nations to standardize the communication of hazards associated with chemicals.

Ladder Safety – A Critical but Overlooked Safety Program

Ladder Safety – A Critical but Overlooked Safety Program

Ladder safety is critical in the workplace to prevent accidents and ensure the safety of employees.  Each year in the U.S. there are more than 164,000 emergency room-treated injuries and 300 deaths that are caused by falls from ladders.  An estimated 81% of fall injuries treated in hospital emergency rooms involve a ladder.  In most situations, ladders were used improperly.  The most frequent ladder injuries include broken bones and head injuries.  This is why it is crucial for employers to comply with ladder safety requirements set by regulatory bodies like OSHA and ANSI.

Ergonomics: Connecting the Human Body and Workplace Environment

Ergonomics: Connecting the Human Body and Workplace Environment

In recent years, the buzz word “ergonomics” has gained some much-deserved attention.  Many have heard the term, yet do not have a full appreciation of its historical importance or significance in today’s workplace.  The concept of ergonomics has Greek origins, with Ergon meaning “work” and Nomos meaning “law”.  It is notable that the principles of ergonomics have been around for centuries, while the emergence of large-scale manufacturing during The Industrial Revolution fueled its foundation.  The term “ergonomics” was initially coined in 1857, recognizing the relationship of the human body to work productivity.
