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.

Save Money, Cut Pollution, Create Jobs: Today is Energy Efficiency Day

Save Money, Cut Pollution, Create Jobs: Today is Energy Efficiency Day

It sure seems like every cause has its day. Just in October alone, there is National Get Funky Day, National Do Something Nice Day, National Taco Day, National Vodka Day, National Manufacturing Day…and the list goes on and on.

Well today, October 5th, 2022 is Energy Efficiency Day and it is a good reminder of the value of saving energy.  The Energy Efficiency Day website’s tagline is “Save Money. Cut Pollution. Create Jobs.”

Eliminating or Minimizing Exposure to Bloodborne Pathogens in the Workplace

Eliminating or Minimizing Exposure to Bloodborne Pathogens in the Workplace

It is estimated that 5.6 million or more workers are at risk for occupational exposure to bloodborne pathogens.  OSHA requires employers provide training to any employee that has the potential to be exposed to bloodborne pathogens or other potentially infectious materials (OPIM). OSHA 29 CFR 1910.1030 (the standard) applies to all workers in the private sector, as well as civilian employees of Federal entities.

2022 Respiratory Protection Week is September 6th – 9th

2022 Respiratory Protection Week is September 6th – 9th

Ensuring that employees are protected from inhaling harmful contaminants requires annual medical clearance and testing to meet OSHA standards. The EI Group’s Occupational Health team is here to help you as a one-stop option to fulfill your annual respirator protection commitments regarding respirator medical clearances and fit testing.

So You Received Your Air Permit – Now What?

So You Received Your Air Permit – Now What?

Most project design/build teams planning new construction or modifications to existing facilities involving sources of air emission understand that these actions require an air permit prior to starting construction.  It is also well known that the emissions, air quality evaluations, and application process should start early, as air permitting is typically on a critical path which can impact scheduling.  If you find yourself as the lucky delegate responsible for air permitting and arrive at the point of receiving the glorious prize of the long-awaited air permit, finally releasing your team to begin construction, CONGRATULATIONS!  You have been victorious, but now what?

Hurricane Season is Upon Us: Are You Prepared?

Hurricane Season is Upon Us: Are You Prepared?

The official hurricane season for the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico, extends from the first of June to the end of November; however, tropical cyclone activity can occur before and after these months.  According to NOAA (National Oceanic and Atmospheric Administration), the peak of the Atlantic hurricane season is September 10, with most activity occurring between mid-August and mid-October.

Why Asbestos is Still an Issue in 2022

Why Asbestos is Still an Issue in 2022

While asbestos has been regulated since 1971 by OSHA and since 1976 by the EPA under 1) the Toxic Substances Control Act and since 1973 under 2) NESHAPs (National Emission Standards for Hazardous Air Pollutants), asbestos remains a concern today.  Why?  I’ll explain, but first let’s define what is asbestos.  Many think asbestos is man-made.  However, it is actually a name given to a group of six naturally-occurring minerals that are mined from the Earth. 

Recent Rise in US COVID Infections Leads to the Rapid Emergence of New Variants

Recent Rise in US COVID Infections Leads to the Rapid Emergence of New Variants

Since the emergence of the initial Omicron variant late last year, COVID has increasingly become more infectious. Since then, multiple Omicron subvariants have emerged, with each new strain being much more transmissible than its predecessor. Omicron BA.5 and its sister, BA.4, currently account for more than 93% of all US covid cases, with BA.5 making up the vast majority of the two variants.

Small and Medium-Sized Enterprise (SME) Involvement is Key to Sustainability Success

Small and Medium-Sized Enterprise (SME) Involvement is Key to Sustainability Success

The headlines surrounding zero carbon emissions have been dominated by some of our largest brands, with the majority of recent progress coming from global corporations looking to reduce CO2 emissions and improve energy efficiency. Much of the initial emission reduction progress by large businesses is due to pressure they are facing from their shareholders and the general public. As a result, the majority of the support, guidelines and incentives available for the development of sustainable programs and for reporting emissions reduction, have been developed for large companies and do not cater to small and medium enterprises (SMEs).
