Inside the EPA’s Proposed Change to the Noise Reduction Rating

Inside the EPA Proposed Change to the Noise Reduction Rating

In anticipation of the EPA's expected change to the Noise Reduction Rating (NRR), Howard Leight has issued a brochure that explains known details of the proposed changes for hearing protectors. Titled, "Inside the EPA's Proposed Change to the Noise Reduction Rating," the brochure is designed as a handy information resource for safety managers, providing background on the impending new rating system and the ANSI testing protocols on which it is expected to be based.


Combating Common Objections to Hearing Protection Wear

Combating Common Objections to Hearing Protection Wear

Keeping workers properly protected from hazardous noise and motivated to wear their hearing protectors is a challenge for any safety manager. With proper training and ongoing encouragement, most workers do wear their earplugs or earmuffs on the job. However, there are always a few workers who feel compelled to raise objections instead of just donning their hearing protectors and getting on with the job.

Introduction to Advanced Back Calculation

What comes to mind when there is a toxic chemical release? The most obvious responses involve evacuation or shelter in place of the people in the path of the plume. To predict the path, area, and severity of a plume impact, you need a dispersion model. The basic information required to initiate a dispersion model is weather data, identification of the chemical, and the rate of the chemical release. However, the Achille' heel of this information is the release rate specification: "How big is the hole?" SAFER Systems has developed and patented a unique scheme for estimating the release rate. The algorithm to implement the scheme is called Advanced Back Calculation® (ABC). The idea basically involves “reverse engineering” a dispersion model. While we usually input the release rate to the dispersion model and obtain the concentration field for the plume-impacted area, in ABC we utilize the concentration field data to estimate the release rate.


Hand Protection: Consumers Opting for Safety, Comfort or Price?

Due to this economic crisis, many manufacturing facilities have started to move away to other regions where manufacturing and labor costs are low. The severity of the situation is compounded by the fact that many industries experience closures and reduced demand for their products or services, consequently reducing the number of employees. As a result there are fewer workers to protect and fewer opportunities for glovem anufacturers to sell their products. Under these circumstances, it is difficult to convince end users to upgrade protective equipment for the task they are performing because, in almost all cases, an upgrade means spending more for hand protection.

Consider Cost vs. Price When Purchasing Hand Protection Products

Everyone wants a bargain, especially in tough economic times. However, purchasing managers and others should take heed when buying personal protective equipment (PPE), including gloves, because sometimes an inexpensive product will actually cost more over time.
