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:
- Substitution of equipment (fundamental first step)
- Categorization of source into vibrational noise and turbulence-based noise
- 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
- Reduce response of vibrating surfaces
- Reduce area of vibrating surfaces
- Reorienting directional noise sources
- Reduction in velocity of fluid flow (air ejection systems, valves, vents and piping)
- Provide sound absorption alternatives
- 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.

Electrical Hazards in Higher Education: Is Your Campus Safe?
Electrical safety is an important consideration for colleges and universities, as many aspects of campus life rely on electrical power, including classrooms, dormitories and as well as research and athletic facilities. Safety measures should be put in place to ensure the health and wellbeing of students, faculty and staff, and to protect against electrical fires, electrical shock and static spark, as well as other hazards.
Are Your Qualified Electrical Workers Really “OSHA” Qualified?
In the General Industry Standard, OSHA does not go into great depth about who is qualified to work on or near energized electrical equipment.
According to OSHA 29 CFR 1910.399, a “Qualified Person” is defined as “one who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment and installations and the hazards involved.” So how does the employer determine and record who is a “Qualified Person”?
Using ISO to Drive ESG
Today, ISO certification is synonymous with quality. There are numerous benefits obtained through ISO certification, including technological, economic and social advantages. You can also improve the quality of your processes and products, better understand your business, enhance the consistency of your operations, reduce waste, save money and gain international recognition. Pursuit of ISO certification is becoming the norm among competitive business operations, especially those who target larger corporations to be an integral part of their supply chain.
New Projects Should Be Evaluated for Air Permit Requirements Early in the Design Process
As an environmental consultant who specializes in assisting industrial clients with air permitting services, I get several calls per year from environmental compliance managers along the lines of the following:
– Management desires to add a new process/modify an existing process/add new equipment.
– The unit(s) have already been purchased and will be delivered to the site next week/month/real soon.
– I need to make sure we have any permits we need and are in compliance with all environmental regulations ASAP!
Preventing Back Injuries in the Workplace
Occupational back injuries account for greater than one million injuries each year according to the Bureau of Labor Statistics (BLS). Such injuries can result in lost time, reduced productivity, increased demands on other workers, costs for medical treatment and insurance premiums and adverse effects on the quality of life for the person affected. Because of this alarming number of back injuries and the detrimental effects for both the employee and employer, prevention is key, along with awareness of the causes and solutions.
Developing Safety and Compliance Training Utilizing the Triple T Method
In today’s workplace, safety and compliance training is more important than ever. Having a comprehensive program in place is essential to protecting your employees and customers as well as your business. Safety training and compliance can help reduce workplace accidents and injuries, protect the environment and prevent legal liabilities. In order to accomplish this, EI recommends using the “Triple T” method when developing training: Tailored, Transparent and Timely.
Arc Flash 101
OSHA describes arc flash as “a phenomenon where a flashover of electric current leaves its intended path and travels through the air from one conductor to another, or to ground. The results are often violent and when a human is in close proximity to the arc flash, serious injury and even death can occur.” I had never experienced what an arc flash incident looked like until I attended EI’s NFPA (National Fire Protection Association) 70E training course and saw a video example of this phenomenon.
The Heat is Coming: Preparing for Inevitable Heat Stress
Even though it is a New Year and we are in the middle of winter, there is no time like the present to prepare for the inevitable hotter months to come, as well as potential heat-related illnesses that impact your workforce. Many of you may be unaware that last April, OSHA added Outdoor and Indoor Heat-Related Hazards to its National Emphasis Program (NEP). This pioneering effort reinforces OSHA’s advanced notice of proposed rulemaking issued in October 2021 which marks the development of a standard that protects indoor and outdoor workers from hazardous heat. While most of us remain bundled up in our winter coats, employers can start acting now to ensure controls are in place for employees during the summer heat as well as remain prepared for OSHA heat-related inspections.
Scaffolding Fatalities – A Preventable Loss
On Monday of this week, three people were killed, and two others injured after a scaffolding collapse at a construction site in Charlotte, North Carolina. All work at the site was halted after the victims fell approximately 70 feet when the scaffolding came apart. The Occupational Safety and Health Administration (OSHA) is assisting with the investigation as to the cause of the collapse. A similar incident occurred in 2015 when three construction workers were killed when scaffolding collapsed as it was being dismantled at a high-rise construction site in downtown Raleigh, North Carolina.
Twas the Night of Confined Spaces
Twas the night before the largest (and only) product distribution event of the year and the facility, in the coldest climate on Earth, was abuzz with bustle and frenzied activity. Employees of shall we say “a smaller stature,” were busy transporting parcels, both large and small, from infinite rows of shelving to the plant’s loading docks and onto an awaiting magical sled via forklifts. Of course, all of these smaller stature employees were over 18 years of age in accordance with OSHA’s 29 CFR 1910.178 standard for Powered Industrial Trucks.
