Washington State Hearing Conservation Considerations

Safety and Health Matters: Washington, Oregon, Idahoby Fred R. Caron, CSP

Hearing loss is usually insidious, occurring gradually over a long period of time. It can be temporary or permanent based on the type of hearing loss. Hearing loss happens so gradually the person affected usually does not notice it until conversations become difficult, especially in situations where background noise is occurring. It can also happen instantaneously such as during an incident like an explosion or sharp blow to the head.

Causes of Hearing Loss


Typical industrial hearing loss can be caused by long term exposure to loud noises and sometimes exacerbated by a combination of loud noises and exposure to certain chemicals on the job such as toluene, xylene, n-hexane, organic lead, mercury and others [see Occupational Ototoxins (Ear Poisons) and Hearing Loss for more information]. While not much research has been conducted on the combination, many Industrial Hygienists and Industrial Audiologists have arrived at this conclusion.


Noise induced hearing loss can also be caused by exposures in settings other than industrial or work related experiences. For instance, loud music at concert settings has been found to be as high as 120 decibels which exceeds allowable OSHA/WISHA noise standards. Off the job noise can also be contributed to by wood cutting with power saws, which typically can exceed 105 decibels. Because of this, many companies encourage their employees to take ear plugs home for use.

TENORM-Driven Radiation Safety in the Aftermath of the PADEP NORM Study

By: Dr. Alan Fellman, CHP

The recent NORM study published by the Pennsylvania Department of Environmental Protection (PADEP) found potential radiological impacts in several phases of Marcellus Shale gas operations. As a result of their findings, organizations involved in several types of activities are going to need to include radiation safety as a part of their occupational EH&S programs.

This post defines the radiation safety training and procedures that are needed to ensure worker and public safety as well as attain compliance with all State and Federal NORM guidance and regulations. The PADEP study summary and conclusions are provided at the very end of this post.

PADEP recommends several NORM related activities for the oil and gas industry. It’s not a “one size fits all” approach; rather, the type and scope of radiation safety activities are dependent on the facility type. Some radiation safety needs identified by PADEP are shared among affected industry segments, while others are unique to just one or two types of operations. The entirety of the radiation safety recommendations can be divided into training and procedures. [Continue reading…]
