Differences Between a Respirator and a Surgical Mask

Want to know what the general differences between a respirator and a surgical mask?  Watch the following video.

In summary,

A respirator:

  • reduces exposure to airborne contaminants
  • specifically fits you
  • must be NIOSH certified, if required by your employer
  • protects against many airborne infectious diseases

A facemask:

  • loose fitting disposable mask
  • help stop large droplets from being spread by the person wearing it
  • help stop particles from reaching the mouth/nose of the person wearing it
  • airborne particles can reach the individual wearing it via gaps
  • FDA approved

Surgical N95 respirators:

  • provide respiratory protection in the healthcare setting
  • should be used in conjunction with other controls (engineering & administrative)

EPA Continues Study on Air Quality Near Schools

school

The EPA is continuing its study of assessing the outdoor air near schools for toxic contaminants.  This study is based upon several factors, including: results from an EPA computer modeling analysis, the mix of pollution sources near the schools, results from an analysis conducted for a recent newspaper series on air toxics at schools, and information from state and local air pollution agencies (See OHShub.com’s original post on the EPA Study on Outdoor Air Near Schools).

Some of the chemicals that will be monitored, include:

  • Carbonyls
  • Diisocyanates
  • Metals
  • PAH’s
  • VOC’s
  • Hexavalent Chromium, and
  • 4,4-methylenedianiline

Data has started to role in on most of the schools included in the study and can be found HERE

According to the EPA:

  • Monitoring at the schools will be phased in over the next three months. In some states, monitoring equipment is readily available and can be quickly moved to the schools to be monitored. EPA will purchase equipment for others.
  • The monitors will measure two types of pollutants in the outdoor air at the priority schools: pollutants that are in gas form, such as benzene; and pollutants that are in particle form, including metals such as hexavalent chromium, manganese or lead. The pollutants monitored will vary by school. EPA will identify pollutants to measure at each school based on the best available information about the pollution sources in the area. EPA and states also will install equipment to measure wind speed and direction at each school during the monitoring.
  • Monitors will be in place at each school for 60 days to provide a snapshot of monitored toxic pollutants in the outdoor air. The monitors will sample air quality on 10 different days during that time. The samples will be analyzed by the laboratories EPA uses for air quality analysis. To ensure the data is sound, EPA and state air agencies will check monitors to be sure they are operating correctly, inspect the laboratories, and review the data for any anomalies.

The Hidden Cost of Workplace Fatalities: 43 Billion Dollars

dollar_signWhile even the non-fatal injury can cost a company ten’s of thousands of dollars (as noted in OHShub.com’s post: The Hidden Cost of Unsafe Behavior: Running the Numbers, even more unbelievable is the cost of a fatality.  NIOSH has produced a document entitled, The Cost of Fatal Injuries to Civilian Workers in the United States, detailing a decade of research (1992 – 2001) into the economic aspect of a workplace fatality.

The method used to calculate the economic burden was the cost-of-illness method: which sums indirect and direct costs.  The cost-of-illness method was used to calculate the mean, median, and total societal costs for the fatalities reported in National Traumatic Occupational Fatalities surveillance system (NTOF).

Indirect costs are calculated for each incident by accounting for the probability of survival, median annual earnings at the time of death, home production costs, earnings growth rate adjustments, and real discount rate. These costs are then added to the direct cost of medical expenses to arrive at the societal cost of fatal injury. The addition of home production costs to this model represents an advancement in methodology over models which simply account for loss of income from wages and presents a point of departure from previous studies. Limitations of this study are varied and include lack of inclusion of some costs of insurance compensation, lack of comprehensiveness of data drawn from death certificates and pay equity.

After the calculations are preformed, over $43 billion dollars (in 2001 dollars) is the cumulative cost for occupational fatalities in the US.

The Hidden Cost of Unsafe Behavior – Running the Numbers

dollar_signAccording to information provided in a report by a nationwide insurance company, approximately 60% of company executives figure that their companies save $3 for every dollar spent on safety programs.  A $10,000,000.00 company that spends 1% of their budget on safety can figure to save approximately $300,000.00.  OSHA puts the figure to be more likely $6 to $1 (i.e. $600,000.00 saved).

If an employee is injured, the insurance company reported that for every dollar cost of an accident, approximately $3-$5 additional dollars are spent as indirect costs.   Therefore, if an accident costs a company $10,000.00, an additional $40,000.00 may be spent on average for that injury, costing the company a total of $50,000.00.

Well, how much money does that $10,000,000.00 company need to make to recoup that $50,000.00?  Assuming the company has a profit margin of 8%, the company will need to increase revenue by an additional $625,000.00 (or 6.25%).

Black Lung Cases on the Rise

minersThe Wall Street Journal has written an article based upon findings of the National Institute for Occupational Safety and Health (NIOSH) indicating a rise in the occurrences of black lung in miners.  Based upon the findings of NIOSH, approximately 9% of miners with 25+ years of experience were positive for black lung in 2005 and 2006, which represents a doubling of  the percentage of those with black lung in the 1990’s.  Black lung is serious health and safety issue in mines, even more so than mine accidents, with more than 10,000 dead since 2000, versus less than 400 from mine accidents.

New monitoring equipment may be potentially introduced by MSHA (Mine Safety and Health Administration) to allow real-time, continuous monitoring of an employee’s dust exposure, versus the standard 8-hour periodic exposure monitoring.  The real-time monitoring would also take into account longer work shifts, which is quite common in the mining industry.

For more information on black lung, NIOSH has produced a video entitled, Faces of Black Lung

OSHA Publishes Weekly Reports on Fatalities and Catastrophes

osha-logo

The Occupational Safety and Health Administration has begun publishing weekly summaries on fatalities and catastrophes (multiple people injured) in the workplace.  Per OSHA regulations, employers must report this data to OSHA within eight hours of an event occurring.  The result of more “open government” within the Obama administration and better access of information by the general public, the reports will provide preliminary information on the cause and result of the incidences.  Once the full investigation is complete, OSHA will update the summaries and the related inspection information, including citations.

You can view the summaries on OSHA’s website HERE.


Online Tool: Is Your Hearing Protection Providing Adequate Attenuation?

hearing_protectionAn extremely useful field tool to determine if you are achieving adequate attenuation with your hearing protection has been devised by NIOSH.  Have you used this in your workplace?  How successful has it been?  Let us know in the comments section of this post.

Loud noise can permanently damage your hearing. It especially affects the sounds that help you understand speech.

Earmuffs, earplugs, and other hearing protection devices can reduce your risk of hearing loss, but only if you get a good fit and wear them properly.

Follow the instructions for the sound player on the right side of this page to perform a quick test of whether you are getting at least a minimal 15 decibel (dB) level of protection.

How it Works

The test sounds are bands of random noise with a center frequency of 1000 Hz. This is the same type of sound used in standard hearing protector ratings including the “American National Standard Methods for Measuring the Real-Ear Attenuation of Hearing Protectors” (ANSI S12.6). Both tracks are the same, but the second track is 15 decibels (dB) louder than the first. Most hearing protectors will block or “attenuate” sound by more than 15 dB if they are the right size and shape to fit your ears and are worn correctly. A sound that is barely audible at your threshold of hearing without hearing protection should be inaudible though hearing protection even if it’s boosted by 15 dB.

Online or Offline Testing:

You can also download the test sounds to check your hearing protection offline with an MP3 player or computer multimedia player. Download or play online, these two tracks:

Track 1: Without Hearing Protection NIOSH QuickFit Without HPD
Track 2: With Hearing Protection NIOSH QuickFit With HPD

For online testing, click the links, goto the .mp3 page, then click the file. Quicktime (or the program you have installed on your computer) will play the file. To download the files for offline testing, right-click the link and choose “Save File As…” or similar selection from the menu.

AIHA Releases White Paper on the Need for Respiratory Protection Research

respiratory_protectionThe American Industrial Hygiene Association (AIHA) recently released a white paper on the need for research of respiratory protection to “enhance the safe and effective use of respiratory protection.”

Among the research needs are:

  1. Measurement of respirator performance
  2. Qualitative fit testing for full facepiece respirators
  3. Appropriateness of fit factor safety margin criterion
  4. In-facepiece measurements
  5. Effectiveness of respiratory protection program requirements
  6. Effectiveness of user seal checks
  7. Organic vapor cartridge desorption

A copy of the full white paper can be found HERE:

  PPEPPTGeneralIndustry1.ppt (5.1 MiB, 2,426 hits)

Many current practices in respiratory protection are based on assumptions, past practices or extrapolation from laboratory studies. Few studies have been done to evaluate the efficacy of, or the need for, each of these practices. AIHA believes the results of research on the practical, applied topics presented in this paper may significantly enhance the safe and effective use of respiratory protection.
