DON’T PAY TOP DOLLAR FOR MOLD TESTING. . . .

Unless You Want It Done Right!

Now you know the rest of the story!  This paper explains why the bargain basement price for mold testing is not necessarily the best.  There are reasons why the price is so low.  Read on.

Ask Why the Mold Testing Price is So Low

Mold TestingThe low price results from several factors.  First of all, the personnel may not have the extensive education, training, and certifications that the higher priced testing companies do.  Second, they may not have to adhere to a code of ethics of a professional certification board.  Third, the types and numbers of samples may be different.  Finally, the report and consultation budget may be cut drastically.  In conclusion, it is a case of apples and oranges – the two cannot be compared.

Mold Testing Prices

The prices can be significantly different.  For example, in our market the low price is $300 for a “mold test” in a small to medium size home or office.  The realistic price to test properly is $750 to $1,150.  That is quite a difference!  It is, but the devil is in the details.  First, the low price work is:

  • 2 air spore traps inside & 1 outside
  • brief report with lab results
  • scant or no interpretation of results

In comparison, the realistic priced work includes:

  • 2 air spore traps & 2 air culture samples inside + 2 of each outside
  • 2 surface tape samples in AC system
  • temperature & relative humidity at same 4 air stations
  • inspection for water intrusion & visible mold
  • moisture mapping with infrared camera & moisture meter
  • American Industrial Hygiene Association (AIHA, aiha.org) accredited lab analysis
  • detailed report with interpretation of results & consultation

That is quite a difference!

Credentials

The low priced company’s staff most likely does not stack up to the realistic priced company.  The staff members may not all have 4 year degrees and if they do, the degrees are not necessarily in biology or a related field.  Both companies should have Florida licensed Mold Assessors (required by law & officially called Mold-Related Services Assessors).  However, the low priced company’s staff will not have a Certified Industrial Hygienist (CIH, American Board of Industrial Hygiene, www.abih.org).  The credential is extremely difficult to get but courts recognize CIHs as expert witnesses.  That means their work is court defensible which is extremely important in today’s litigious society.  No one plans to go to court, but many end up there!

Final Note

ESC is not the low priced company and it does mold testing right.  The firm has taken over more than one job from owners who realize they just threw their money away on low priced testing.  There is even more information in papers on our web site.  They are in our blog section and can be found by clicking on  https://www.escflorida.com/category/indoor-air-quality/.

ASBESTOS POINT COUNTING

Asbestos Point Counting Defined

Point counting is a detailed laboratory method that determines the actual asbestos content of friable building materials.  It shows if the content is greater than 1%.  The federal asbestos regulations for building renovations and demolitions allow point counting.

The actual regulation is found in Chapter 61.145 of Title 40 of the Code of Federal Regulations, otherwise known as 40 CFR 61.145.  Chapter 61 contains the NESHAPs rules (National Emission Standards for Hazardous Air Pollutants).  NESHAPs covers quite a few hazardous air pollutants and asbestos is addressed in Subpart M of Chapter 61.  NESHAPs is enforced by the U.S. Environmental Protection Agency (EPA, www.epa.gov).  State agencies such as the Florida Department of Environmental Protection (www.floridadep.gov) also enforce it.

When to Asbestos Point Count

Do point counting when the material is friable and the initial results are less than 10%.  This more detailed procedure tightens the statistics, providing a more accurate concentration.

Options

What are the options?  First, assume the initial results are correct and the material contains more than 1% asbestos.  Next, abate it prior to disturbance (renovation or demolition).  Otherwise, point count it.

Asbestos point countingThe decision involves money.  The cost of point counting a few samples is a few hundred dollars.  But, the cost of abatement is a few thousand dollars.  In either case, removing the material can cause an inhalation hazard for the workers and occupants.  This is true even for asbestos concentrations less than 1%.  That number is a regulatory number, not a safe, no exposure number.

Decision

Like a lot of construction issues, point counting is a business decision.  The building owner and occupants make the decision, with the building contractor, licensed asbestos consultant, and licensed asbestos contractor.  Consider the potential outcomes.  For example, the owner and occupants may say they want it removed properly by a licensed asbestos contractor whatever the concentration is.  Alternatively, they may not care about the potential exposure and opt for the building contractor to carefully remove it it if it contains less than 1% asbestos.

Can I Reuse My N-95 Masks?

Introduction

This paper is the fourth in a series on the pandemic disease, COVID-19. The first paper focused on safely reopening your business.  The second one concerned face masks, the primary PPE (personal protective equipment). The third paper involved examining the exposure routes. Finally, this one will discuss the reuse of N-95 masks. This has been of great importance during the current pandemic.  That is due to shortages of N-95s and the need to protect everybody.  Further, health care workers and other front line workers must be protected from infected and asymptomatic carriers of the SARS-CoV-2 novel corona virus.

N-95 Masks Not Designed for Reuse

Do not reuse N-95s. Wear them one time and throw them away. Their paper cloth-like material does not stand up well when washed or disinfected. The filtration can be reduced and put the wearer at risk. The elastic bands and the filter material may become distorted.  Then the mask does not seal properly to the face or fit properly. This allows air leakage and defeats the purpose. Also, viruses, bacteria, and physical particles can become trapped on the outside of the filter material and lead to infection when touched.

Short Supply has Forced the Issue

Necessity is the mother of invention! And because the N-95 has come into such demand, we have been forced to explore reuse of these disposable masks. The scientists and regulatory agencies have explored various options and made emergency concessions for the reuse of N-95s. Federal agencies involved include the Center for Disease Control (CDC, www.cdc.gov), Occupational Safety & Health Administration (OSHA, www.osha.gov), and the Food and Drug Administration (FDA, www.fda.gov).

N-95 Masks Reuse Guidelines

The simplest method is to store the N-95 in a closed paper bag and not reuse it until 5 days later. This is not true disinfection but it banks on the virus dying outside of the body, which is typical of most micro-organisms. The CDC identifies the following disinfection methods:

  • Moist Heat (think autoclave)
  • Ultra-violet Light
  • Hydrogen Peroxide

Only trained scientists and medical personnel can use these disinfection procedures. Examine the masks for distortion and damage, then fit test them on personnel.  Just remember – when in doubt, throw it out!

As the Virus Turns

That sums up reuse and disinfection at this time. But stay tuned, because new information and data come in every day!

Skip The Phase I Environmental Site Assessment

I Just Want to Do a Phase II Environmental Site Assessment

We have that telephone call quite often. The caller usually says, “Look, just give me an estimate for a Phase II Environmental Site Assessment. I don’t want to do a Phase I.” To which we respond, “Okay, so you have already had a Phase I done?” “No, but I know it was a gas station.” At which point we explain how skipping the Phase I risks omitting information and data which could affect the type of testing you do in the Phase II.

Due Diligence

We further explain that in so doing, the caller may not be exercising due diligence in determining if the site is or could be contaminated from usage of the itself or properties in the vicinity. Why the concern about due diligence? Well, if due diligence is exercised via a Phase I and, if required, a Phase II, and contamination is found later on, Superfund (CERCLA, Comprehensive Environmental Response, Compensation, & Liability Act, www.epa.gov) is supposed to cover the cleanup. Considering cleanups can start at less than $50,000 and run into the millions, that is nothing to take lightly.

What Could be Omitted on the Site Itself?

Environmental Site AssessmentLet’s use the gas station example. A gas station today is not necessarily a gas station yesterday. In the 1950’s to mid-1970’s, a gas station was normally a full service station, not the convenience store that sells gasoline and diesel fuel today.  Not only did they sell fuel from underground storage tanks, but they quite often dumped used oil, chlorinated carburetor cleaner, and other petroleum based wastes into a used underground storage tank.  And, yes, those tanks leaked just like the fuel tanks.  At the end of the day, they often hosed down the floor of the repair shop and squeegeed it out the door onto the pavement, grass, dirt, road, and storm drains. Oh, by the way, they also had hydraulic oil tanks underground for the lifts, which also leaked.

A lot of the details on the site usage would be missed by jumping to a Phase II. The operations above raise the need to include used oil, solvents, hydraulic oil, and heavy metals from the used oil in the Phase II. But guess what? Prior to it becoming a service station in 1960, it was part of a former celery field for 30 years where every pesticide available was used. And that is an even bigger omission. One would not necessarily have discovered that by skipping the Phase II.

How about the Vicinity?

Well, it turns out, there was a perchloroethylene (perc) contaminated dry cleaner right across the street. But it is clear across the street, who cares? You should because that contamination could have migrated to your site and you could end up bearing the cleanup cost. And by the way, the ASTM E 1527 -13 Standard E-27 for Phase I’s (www.astm.org) considers that an adjacent property – the road offers no separation. Oh, and right down the street was a paint and body shop which was less than meticulous in handling and disposing solvents and paints. Matter of fact, the groundwater plume from that operation is now at the edge of your site.

Conclusion

So that should be enough information for you to decide that skipping a Phase I is not a good idea. If you do, the consequences may be more than you can stand – emotionally and financially!

Industrial Hygiene Testing Results

Industrial Hygiene Blogs So Far

This is the ninth in a series of blogs on industrial hygiene (IH). Our last blog covered the selection of an industrial hygiene testing firm. The current blog will address what to do with the industrial hygiene testing results.

The Report

Most likely, if you selected a reputable firm with experience and a Certified Industrial Hygienist on staff, you will end up with a thorough report. The objective and scope of work will be stated and the methods will be identified. Details of the testing event will be provided. Then, the results will be presented and evaluated. They will be compared to regulatory limits of the U.S. Occupational Safety & Health Administration (OSHA, www.osha.gov) and recommended limits of organizations such as the American Conference of Governmental Industrial Hygienists (ACGIH, www.acgih.org) and the National Institute for Occupational Safety & Health (NIOSH, www.cdc.gov).

Oftentimes, we are asked why limits beyond OSHA’s are included. The reason is that in many cases, OSHA’s limits are 40 years old. They have not been able to keep up with new information and data, because most of their moves are challenged in court. We are talking worker protection here and minimizing your company’s liabilities. The other limits such as ACGIH’s Threshold Limit Values® (TLVs®) and NIOSH’s Recommended Exposure Limits (RELs) are more current and can be considered industry standards. Our legal friends tell us that you can be held accountable to industry standards in a court of law. Therefore, you want to take these recommended limits seriously.

Control Options

So, let’s say your report shows that the airborne concentrations of certain chemicals in your plant exceed the regulatory or recommended limits. What are your options to control the situation? OSHA would prefer that you use administrative controls or engineering controls INDUSTRIAL HYGIENE TESTING RESULTSfirst and as a last resort personal protective equipment (PPE).  Why is PPE considered a last resort? Because it is the last line of defense.  If it fails, your workers may be ex-posed to hazardous airborne concentrations. Therefore, OSHA prefers that the hazard be eliminated or reduced to a level that is either nonhazardous or is as low as reasonably achievable.

Here are a few examples of controls. Administrative controls may involve substitution of chemicals with less hazardous chemicals, or shift rotation to minimize the time of exposure, or changing the task so the worker is less exposed, or training employees properly. Engineering controls could include exhaust ventilation, automated dispensing of chemicals, general ventilation, and more. Of course PPE includes respirators, safety glasses, welding curtains, protective clothing, gloves, and on and on.

What Next?

Assemble the appropriate players and evaluate the different control options. The cost, effectiveness, and likelihood to be used are real factors for serious consideration. Once a selection is made and the controls are implemented, decide when to retest. After all, you probably won’t know whether the controls are effective without data.

So that concludes our blog on what to do with the results from completing industrial hygiene testing. And we have now covered a lot of ground in the field of industrial hygiene.

Industrial Hygiene Testing Firm Selection

Industrial Hygiene Blogs So Far

This is the eighth in a series of blogs on industrial hygiene (IH). Our last blog covered the design of industrial hygiene testing. The current blog will address how to select an industrial hygiene firm to do the testing.

Selection Players

Most likely, you will need other players besides yourself to select the firm to do the industrial hygiene testing. It often takes representatives from Safety, Facilities, Maintenance, Operations, and Purchasing. Each of these players has a different interest and plays a different role in the project. They have interests in worker protection, compliance, production efficiency, and expenditure of money and man hours. They must communicate on the project.  A meeting may be necessary.

Testing Objective

INDUSTRIAL HYGIENE TESTING FIRM SELECTIONAssuming that you are in charge of Safety, you need to control the selection and must make sure that the players understand the objective. You want to be clear and concise. For example, you may advise the players that our objective is to determine if our painters applying the primer and finish coats are being overexposed to methylene chloride. They spray the paints off and on for a total of six hours during their eight hour shift five days a week. We have exhaust ventilation in the paint spray booths and they wear full facepiece air purifying respirators equipped with organic vapor filters piggybacked with particulate filters. Assuming the respirators have the proper protection factor, what are they exposed to if the respirator fails or they do not don it properly? We want to know what the airborne methylene chloride concentration is on an eight hour time weighted average (TWA) basis and on a fifteen to thirty minute short-term basis. Does it exceed the limits of OSHA (www.osha.gov) or ACGIH (www.acgih.org)? If so, we need to reduce their exposure.

Selection Criteria

Again, you will need to take the lead in suggesting the criteria to select the industrial hygiene testing firm. You may specify that the firm has on staff a Certified Industrial Hygienist (CIH), ten years of experience, a quick response time, and a reasonable turnaround time. Other players will have their criteria.

Purchasing may want to check the firm out on Dun & Bradstreet to make sure they are financially sound.

Request Estimate

Once the criteria have been established, request an estimate from one or two firms. Define the objective, operation, paints, and shift. The industrial hygiene firm may or may not want to visit your plant before submitting the estimate.

Specify all of your company’s criteria and conditions in completing the work. Let the firm(s) know up front what the expectations and schedule are.

Review Estimate

You need to review the estimate first and request revisions if necessary. Once it meets all the requirements, the other players need to review either it or your recommendation. Reach a decision and award the job, then get it done.

So that concludes our recommended procedure to select an industrial hygiene firm to complete your testing. In our next blog in this series, we will discuss what to do with the results.

Industrial Hygiene Testing Details

Industrial Hygiene Blogs So Far

This is the seventh in a series of blogs on industrial hygiene (IH).  The first one explained that industrial hygiene was the recognition, evaluation, and control of hazards in the workplace.  The second blog defined a hazard as a source of danger or an agent which has the potential to cause harm to a vulnerable target.  Sources of hazards were identified in manufacturing, construction, maritime, office, and other workplaces.  Different types of resources were identified such as guidelines provided by the U.S. Occupational Safety & Health Administration (OSHA, www.osha.gov) and the National Institute of Occupational Safety & Health (NIOSH, www.cdc.gov/niosh).

The third blog focused on the recognition or identification of hazards.  The fourth one walked you through an example of hazard recognition for a specific operation.  The fifth blog provided an overview of the evaluation of industrial hygiene hazards.  Then the sixth blog presented an overview of industrial hygiene testing as one method to complete the evaluation of potential industrial hygiene hazards.  Finally, this current blog will cover the design of industrial hygiene testing.

Industrial Hygiene Testing Objective

Industrial Hygiene Testing DetailsThe specific industrial hygiene testing depends on the source of the hazard and the operation.  In general, the first step is to define the objective of the testing.  For example, the objective may be to determine if there is an oxygen deficient atmosphere in a chemical vat during a cleanout operation.  Details are needed on the operation to establish the testing approach.  For the vat example, the operation may involve two maintenance employees who clean out the vat during a four hour period once a week.  The vat is emptied  and dried out on Friday.  On Monday, the two employees are lowered down into the vat after donning personal protective equipment.  They use absorbent cleaning towels and an innocuous cleaner.  The next step is to determine how the objective will be met.

Industrial Hygiene Testing Details

The objective will be met by selecting the right procedure and executing it.  To flesh out the details, start by answering  the what, who, when, how, and where questions.  What testing method will best meet the objective?  Who should complete the testing?  How long will the testing last?  What is the time table for getting the results?  When will a verbal report be provided?  What will be the specific content of the written report?  When will the written report be provided?  If the testing confirms there is a hazard, will corrective action be recommended?

Finally, identify any special requirements of your company in having the testing performed.  For example, are photographs of the testing required?  What about written descriptions of the tasks which the employees perform during testing?  Make no assumptions as to what will be included in the testing or report.  It is better to review it up front, rather than to be disappointed in the end.

So that concludes our overview of industrial hygiene testing.  In our next blog in this series, we will discuss how to select an industrial hygiene firm to do the testing.  That process often includes multiple players and departments at your company.

Testing Methods

The testing method selection depends on the type of hazard.  So you may have an inhalation hazard due to the presence of one or more of the following:

industrial hygiene testing overview

  • Chemicals
  • Particulates
  • Oxygen Deficiency
  • Toxic Gases
  • Biological Organisms

Or, you may have a noise hazard.  Alternatively, you may have a heat stress hazard.  Finally, you may have a radiation, biological, or any of several other hazards.  It should be obvious that different testing methods are used for different types of hazards.

So testing methods are varied.  For airborne hazards, there are sampling pumps and collection media analyzed in a lab.  There are also badges that can be worn for certain time periods which are then analyzed in a lab for volatile organic compounds, radiation, or other constituents.  Electronic meters are available to instantaneously measure certain chemicals, particulates, toxic or explosive gases, noise, radiation, or other parameters.  These devices may also measure the oxygen concentration in the air to determine if it is deficient.  Air samples can also be collected and analyzed in a lab for bacteria or mold.

Those are just some of the testing methods.  And again, they are selected based on the potential hazard and the operation.  The actual selection is part of testing design which is covered in our next blog.

So that concludes our overview of industrial hygiene testing.  In the meantime, if you need any help, Environmental Safety Consultants (www.escflorida.com) is here.  We are a Florida licensed environmental engineering company with a CIH on staff.  We have the credentials and experience to help you complete your industrial hygiene project.

Evaluation – Industrial Hygiene Hazards

Industrial Hygiene Blogs So Far

This is the fifth in a series of blogs on industrial hygiene (IH).  The first one explained that industrial hygiene was the recognition, evaluation, and control of hazards in the workplace.  The second blog defined a hazard as a source of danger or an agent which has the potential to cause harm to a vulnerable target.  Sources of hazards were identified in manufacturing, construction, maritime, office, and other workplaces.  Different types of resources were identified such as guidelines provided by the U.S. Occupational Safety & Health Administration (OSHA, www.osha.gov) and the National Institute of Occupational Safety & Health (NIOSH, www.cdc.gov/niosh).  The third blog focused on the recognition or identification of hazards.  The fourth one walked you through an example of hazard recognition for a specific operation.  And this blog will provide an overview of the evaluation of industrial hygiene hazards.

Types of Evaluation

So you have identified the potential hazards through the recognition process and now you are ready to evaluate the hazards.  There are a few ways that this can be done.

One is to estimate what the air concentrations of the chemical or dust of concern are from analyzing the operation or manufacturing method.  For example, certain assumptions are made as to how much of a paint or substance ends up on the part and then estimate how much ends up in the air.  You would have to use the Safety Data Sheet and Technical Data Sheet to determine the concentration of the hazardous chemical in the product being used or applied.  You have to determine how much goes off as a vapor for things like paint to estimate volatile organic compounds (VOCs, such as solvents) and how much overspray there is to account for particulates.

Hygiene HazardsAnother option for an operation that is established and being used is to monitor the complaints or adverse health conditions.  Then those are compared to potential health impairments identified on the Safety Data Sheet.  This may actually tell you what the constituent of most concern is.  Take note that we are not recommending this approach since it can put workers at unacceptable risk.  However, we have had enough years in the field that tell us processes are often established and used regularly without the proper evaluation.

Another approach is control banding.  This groups chemicals according to similar characteristics, which may be physical or chemical.  Then, based on these characteristics, you decide how the chemical will be used and what the anticipated exposure hazards will be.  Appropriate work methods and controls are selected to eliminate or at least minimize the workers’ exposures.

Finally, there is industrial hygiene testing.  When properly completed, this is the best method to conclusively decide if there is truly a potential exposure to the workers.

So that concludes our overview of hazard evaluation in industrial hygiene.  In our next blog in this series, we will discuss specific evaluation of potential industrial hygiene hazards.  That process often includes industrial hygiene testing.

Industrial Hygiene Hazard Recognition Example

Industrial Hygiene Blogs So Far

This is the fourth in a series of blogs on industrial hygiene (IH).  The first one explained that industrial hygiene was the recognition, evaluation, and control of hazards in the workplace.  The second blog defined a hazard as a source of danger or an agent which has the potential to cause to harm to a vulnerable target.  Sources of hazards were identified in manufacturing, construction, maritime, office, and other workplaces.  Different types of resources were identified such as guidelines provided by the U.S. Occupational Safety & Health Administration (OSHA, www.osha.gov) and the National Institute of Occupational Safety & Health (NIOSH, www.cdc.gov/niosh).  The third blog focused on the recognition or identification of hazards.  And, this blog will walk you through an example of hazard recognition for a specific operation.

IH Hazard Recognition Example

Industrial RecognitionLet’s say the operation is spray painting a finished metal part before shipping.  The part comes into the paint spray booth already deburred and sanded.  It is ready to paint.  The operation involves the following tasks:

  1. Clean/degrease the part
  2. Allow part to dry
  3. Fill paint pot with primer
  4. Spray part with primer
  5. Allow part to dry
  6. Sand primed surface to smooth it before final coat of paint
  7. Clean sanding debris from part
  8. Fill new paint pot with finishing paint
  9. Spray paint with finishing paint
  10. Allow to dry then send to shipping department
  11. Clean out spray guns and paint pots

So what are the hazards that you can identify?  Steps 1 and 2 could present an inhalation and skin absorption hazard due to the use of solvents containing volatile organic compounds (VOCs).  This could also be true for Steps 3, 4, 5, 8, 9, 10, and 11 depending on the chemicals present in the primer and finish paint.  Additionally, during spraying, there could be a hazard associated with particulates.  This is also true of the sanding and cleanup in Steps 6 and 7.  There also may be metals of concern in the sand paper.

In terms of recognizing the specific potential hazards of most concern, that will depend on the constituents in the cleaner/degreaser, primer, sandpaper, and finish paint.  Without that information, the potential hazards of most concern will likely be vapors and particulates from the spraying steps.  How can you know?  That is where the industrial hygiene evaluation comes in.  But that will be covered in our next blog.
