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.

Preparing Your Occupational COVID Testing Program. Are You Ready?

Preparing Your Occupational COVID Testing Program. Are You Ready?

Wherever business managers lean politically, most concur that routine workplace testing of employees to identify COVID carriers is an effective measure to minimize occupational COVID transmission. The virulent nature of the Omicron variant (akin to measles in virulence) makes rapid antigen testing of the workforce a common sense choice to prevent them from spreading COVID to coworkers. What better concept to identify those employees who are infected with COVID and isolate them from their fellow workers to “Nip occupational COVID transmission in the bud!?” 

Sustainability and ISO Management Systems: Are ISO Standards a Bunch of Hooey or a Helpful Sustainability Tool?

Sustainability and ISO Management Systems: Are ISO Standards a Bunch of Hooey or a Helpful Sustainability Tool?

In recent years market drivers have played a more pivotal role in convincing management to embrace a corporate sustainable culture. In fact, even without new regulations or legal requirements, 90% of major US companies published a sustainability report in 2019, up from 20% in 2011. Sustainability has become a means of gaining market visibility and differentiation. This shift in business is about drivers in the marketplace and not regulation. Sustainability efforts at your facility may be driven by the requirements of multi-national companies with headquarters in Europe or possibly the requirements of customers within your global supply chain.

Selling Corporate Sustainability to Management

Selling Corporate Sustainability to Management

Convincing employees and management to embrace corporate cultural change is certainly nothing new. One needs to look no farther than the successful business models which promote occupational safety, aimed at lowering workplace accidents! A successful occupational safety program requires a cultural change and encourages participation among the entire workforce. Just like safety, promoting a sustainable culture at work is simply good business and yields a significant, long-term ROI.

The Fundamentals of Confined Spaces

The Fundamentals of Confined Spaces

The Occupational Health and Safety Administration (OSHA) has implemented stringent regulations when identifying confined spaces in the workplace.  Such standards are due to the number of fatalities associated with occupying these spaces.  

The End of Leaded Gasoline

The End of Leaded Gasoline

The era of leaded gasoline has finally come to an end. Yes, you read that correctly. Leaded gasoline is finally no longer being used anywhere on the planet. Environmental activists, government regulators, and people with common sense are happy to see the poisonous additive is no longer used.

What Does Swiss Cheese Have to Do with Preventing COVID-19?

What Does Swiss Cheese Have to Do with Preventing COVID-19?

We recently discussed how to minimize the spread of the highly contagious Delta Variant in the workplace with Rapid Antigen Testing. As more businesses return employees to the workplace, whether it be to manufacturing facilities or commercial office spaces, it remains critical to keep everyone safe and healthy.  Absenteeism driven by the need to quarantine both COVID positive employees, as well as the general workforce with whom they closely interacted significantly impacts productivity.

Preventing Heat-Related Illnesses on the Jobsite this Summer

Preventing Heat-Related Illnesses on the Jobsite this Summer

As record heat waves continue to scorch throughout the U.S this summer, it is important to know the dangers and warning signs of heat stress. While temperatures climb during the summer months, the increase risks of heat- related illnesses or HRIs, increase as well. According to a study by the CDC, approximately 90% of heat related deaths occur during the months of May, June, July and August.

How to Combat the Highly Contagious Delta Variant in the Workplace: Rapid Antigen Testing – A Game Changer

How to Combat the Highly Contagious Delta Variant in the Workplace: Rapid Antigen Testing – A Game Changer

As the highly contagious delta variant spreads across the United States, a surprising number of vaccinated Americans are testing positive for COVID-19. The promise of a “return to normal” has hit an unexpected roadblock with the growing risk of these breakthrough infections. According to an early new study, individuals infected with the delta variant may carry more than a thousand times more virus particles, testing positive up to two days earlier than those infected with the original SARS-CoV-2.
