Electronics Recycling for the Conscientious Consumer

So, Christmas is over. You can all breathe a sigh of relief (until you receive your credit card bill, that is). Maybe you received all the presents you schemed for, and hopefully you gave more than you received. Chances are that you received some shiny new electronics � a new cell phone, a new TV, the latest tablet computer. The question is: What do you do with the old electronics?

There are many options for you to choose from:
  • If the electronic equipment is still fairly new and functional, the manufacturer might buy it back, refurbish it, and re-sell it at a reduced price. 
  • If the electronic equipment is still fairly new and functional, you can always factory reset it and sell it yourself on an online platform (think eBay or something similar).
  • If the electronic equipment is still functional, ask around in your social network to see if anyone has use for it � just because you�re done with it doesn�t mean someone else won�t find it useful. 
  • If the electronic equipment is still functional, consider placing it back to factory reset and donating it to charities such as Goodwill or Deseret Industries. 
  • If the electronic equipment is non-functional, PLEASE don�t just throw it in the trash.

Let�s talk about electronics recycling. The options below are for Arizona residents.
  • U.S. Environmental Protection Agency (EPA) � There is an �Electronics Donation and Recycling� page that you can visit to learn the benefits and importance of electronics recycling, and see which companies will accept electronics for recycling on a national scale (i.e., Best Buy, Dell, Staples, LG, and others). 
  • Arizona Department of Environmental Quality (ADEQ) Recycling Program � This is a useful site where you can just plug in your zip code and select the item(s) you want to recycle. The site will tell you the closest location that will accept the kind of waste you are hoping to recycle. 
  • City of Phoenix � No, you can�t recycle your TV or cell phone in your normal recycling container. City of Phoenix recommends contacting Westech Recyclers for electronics recycling. There are community recycling collection events scheduled throughout the year.
  • City of Mesa � According to the City of Mesa�s website, �Residents can recycle their old electronic equipment, such as computers, televisions, stereo equipment, etc., through the Salt River Landfill Electronics Recycling Program. In addition, retailers such as Best Buy also offer an electronics recycling program. Computers in working condition and other select electronics may also be donated to AzSTRUT.�
  • City of Flagstaff � Flagstaff has a �Accepted Waste Chart� that explains where each type of waste to be disposed or recycled should be taken by homeowners.
  • City of Tucson � The City�s �Keep Tucson Clean and Beautiful� website showcases the recycling vendors for various types of materials. 

A simple Internet search will tell you the available options for electronics recycling in your area. The obvious benefits of recycling your electronics are that they won�t end up in the landfill (possibly leaching metals and hazardous chemicals into soils and groundwater) and many of the components can be re-used to make new electronics (reducing the need for more raw resources). Be a good steward of the environment and recycle or donate your old electronics.

Bored in Asbestos Refresher Class?

I spend a lot of time in continuing education classes, including annual asbestos refresher classes. Some of the classes are a regulatory requirement and others are topics I'm interested in. Certifications such as the Certified Industrial Hygienist (CIH), Certified Safety Professional (CSP), and Certified Indoor Environmentalist (CIE) require a certain amount of contact hours for continuing education.

In a given year, I devour an average of 100 hours in conferences, refresher classes, and continuing education as shown below:


I recently spent part of a morning texting a friend/client (at their request) to help them stay awake in asbestos refresher class. This got me thinking about all the times I attempted to keep focused during class in the 8+ years of various asbestos refreshers, to little avail.

Attendees to asbestos refresher class can be very disruptive, using the class as a vehicle to network (loudly) with consultants, contractors, and building owners or representatives. Sometimes they'll spend the entire day texting and emailing, jumping out of their seats to take a call in the lobby, speaking just loud enough so the rest of the class can see how busy and important they are. Others open up their laptops and just work on projects during the refresher class. If there are snacks or coffee provided, you're guaranteed to have some obnoxiously loud slurpers or chewers. 

Here's some of the ways I quietly and unobtrusively entertain myself during asbestos refresher class:


And, of course, I'll pay attention to new letters of interpretation or interesting arguments, answer questions when prompted, and complete the end of course test or assessment in record time.

I drafted this latest Industrious Hygienist manga during the text session with my friend/client, hope you enjoy it.

The Industrious Hygienist is never bored in asbestos refresher class!

DIY Safety Data Sheet Revision in Three Easy Steps

Manufacturers and importers of hazardous chemicals have until June 1, 2015 to update their labels and material safety data sheets to be in compliance with the Hazard Communication Standard (HCS) final rule promulgated by the Occupational Safety and Health Administration (OSHA). While you�re patiently waiting for manufacturers to conduct the revisions to labels and updating material safety data sheets to reflect the 16-section format required for Safety Data Sheets (SDS), you still have to train your employees in the new label elements and new SDS format.

OSHA has put together Quick Cards for sample labels and SDS, explaining the new requirements, but some employees and safety professionals may find it difficult to train employees without real, concrete examples. Many manufacturers and importers may also be moving slowly on their revisions due to the perceived difficulty of completing the revisions.

To assist safety professionals and industrial hygienists in their training, here�s some do-it-yourself (DIY) 3-step guidance on preparing your own labels and SDS.

Step 1: Review the requirements for SDS and labels.

First look at the OSHA sample label and list of the 16 required sections for an SDS. If you haven�t looked at your HCP lately, it�s also a good time to revise and update your program. OSHA provides guidance on establishing and maintaining your HCP in their �Small Entity Compliance Guide for Employers That Use Hazardous Chemicals.� 

Next, it might be helpful to review Annex 4 of theGlobally Harmonized System for the Classification and Labelling of Chemicals(GHS), Third Revised Edition (2009). Annex 4 is entitled �Guidance on the Preparation of Safety Data Sheets (SDS)� and explains the purpose of each of the 16 sections in detail. 

Please note that OSHA cannot enforce the content of Sections 12 to 15 of the SDS, as these sections are enforced by other regulatory agencies like the U.S. Environmental Protection Agency (EPA) and U.S. Department of Transportation (DOT) that have not yet adopted GHS.

Step 2: Figure out the hazard classification and category of the substance or mixture.

This is the hardest part of SDS and label preparation � figuring out how to properly classify the substance or mixture. If you want to read through GHS Part 2: Physical Hazards and Part 3: Health Hazards to get an idea of the complexity of this task, you can, but you may find it overwhelming.

You�ll need some knowledge of toxicology and management of hazardous materials to complete this task. If you�re lucky, you�ll find a SDS already prepared by another manufacturer (usually with international capability who already has GHS-compliant SDS) that contains the hazard classification of the substance or mixture.

You have to assess if your chemical constitutes a physical hazard, a health hazard, or both. Some examples of physical and health hazards are included below.

Physical Hazard

Explosives
Flammable Gases
Flammable Aerosols
Gases Under Pressure
Flammable Liquids
Self-Reactive Substances and Mixtures
Pyrophoric Solids
Oxidizing Liquids
Organic Peroxides
Corrosive to Metals

Health Hazard

Acute Toxicity
Skin Corrosion/Irritation
Serious Eye Damage/Eye Irritation
Respiratory or Skin Sensitization
Germ Cell Mutagenicity
Carcinogenicity
Reproductive Toxicity
Specific Target Organ Toxicity � Single Exposure
Specific Target Organ Toxicity � Repeated Exposure
Aspiration Hazard

Physical Hazard: Here�s where the hazardous materials management knowledge will come in handy. You�ll want to find the upper and lower flammable limit/range of your chemical or mixture at standard pressure; understand whether you have a compressed gas, liquefied gas, refrigerated liquefied gas, or dissolved gas; know the flash point for your chemical or mixture; research the burning rate of your flammable solid; research the heat of decomposition; and know the corrosion rate or steel and/or aluminum.

Health Hazard: This is where knowledge of toxicology and ability to search various institutional databases will be useful.

Acute Toxicity:look up the various lethal doses for each anticipated exposure route (oral, inhalation, dermal, etc.). The LD50 indicates the lethal dose in 50% of test subjects (oral, dermal, and other routes) and the LC50 indicates the lethal concentration in 50% of test subjects (inhalation route).

Useful sources for health hazards:

  • National Institutes of Health ToxNet � Hazardous Substances Data Bank (HSDB): Look up the chemical(s) by Chemical Abstract Service (CAS) number or chemical name. This provides information on human health effects, emergency medical treatment, animal toxicity studies, environmental fate, chemical/physical properties, chemical safety and handling, and occupational exposure standards.
  • Centers for Disease Control and Prevention (CDC), National Institute for Occupational Safety and Health (NIOSH) Pocket Guide to Chemical Hazards: Look up the chemical(s) by CAS number of chemical name. This provides the synonyms and trade names, conversion rates, DOT Emergency Response Guide number, Immediately Dangerous to Life and Health (ILDH) concentration, recommended measurement methods, exposure limits, physical description, exposure routes, symptoms, incompatibilities and reactivities, personal protection, and first aid recommendations.
  • Registry of Toxic Effects of Chemical Substances (RTECS), linked from NIOSH Pocket Guide to Chemical Hazards: This provides skin and eye irritation data, mutation data, reproductive effects, and acute toxicity data. 
  • OSHA Occupational Chemical Database: This compiles information from the DOT Emergency Response Guidebook, NIOSH Pocket Guide to Chemical Hazards, and OSHA Chemical Sampling Information webpage.
  • Agency for Toxic Substances and Disease Registry (ATSDR) Toxic Substances Portal: Provides toxicological profiles, public health concerns, and health effects; search by CAS number of chemical name.
  • ATSDR Medical Management Guidelines: Use for basic chemical and exposure information, a summary of potential health effects (acute and chronic), routes of exposure, and incompatibilities.

Step 3: Start Writing the SDS.

Once you have the hazard classification for each chemical or mixture, the rest of the SDS is mostly data gathering.

Section 1 � Identification

Include the product identifier (as used on the label), other means of identification, recommended use, supplier�s details, and emergency phone number.

Section 2 � Hazard Identification

Using the hazard classification, go to Annex 3 for the �Codification of Hazard Statements, Codification and Use of Precautionary Statements and Examples of Precautionary Pictograms.� Look through the listed Hazard Statement codes for physical hazards in Table A3.1.1 and it will tell you what hazard statements and pictograms belong on the SDS and label based on the hazard class. There are also tables for the various Precautionary Statements (prevention, response, storage and disposal). Or, to make it simpler, on page 336 of Annex 3, there is a series of tables encompassing much of the rest of the Annex showing the required signal word, hazard statement, symbol, and precautionary statement(s) based on the hazard classification and associated hazard category. It makes Section 2 very simple to accomplish.

Pictograms can be downloaded as .JPG files from OSHA here.

Health Hazard Pictogram

Section 3 � Composition/Information on Ingredients

This should be present on the original material safety data sheet you are converting to SDS format.

Section 4 � First Aid Measures

This information can be obtained from the NIOSH Pocket Guide to Chemical Hazards, DOT Emergency Response Guidebook, ATSDR Medical Management Guidelines, or ToxNet HSDB. Provide first aid measures for each anticipated route of entry (eye contact, skin contact, inhalation or breathing, ingestion or swallowed).

For information about the most important symptoms (acute and delayed), and indication of immediate medical attention and special treatment needed, the sources listed above for researching health hazards will be useful.

Section 5 � Fire-Fighting Measures

Information from this section can be easily obtained from the NIOSH Pocket Guide to Chemical Hazards and DOT Emergency Response Guidebook, by finding the Guide number that matches the chemical(s) on your SDS and reviewing the emergency response fire information. Make sure to include the ILDH concentration from the NIOSH Pocket Guide to Chemical Hazards, as applicable.

Section 6 � Accidental Release Measures

Information from this section can be easily obtained from the DOT Emergency Response Guidebook, by finding the Guide number that matches the chemical(s) on your SDS and reviewing the emergency response spill or leak information.

Section 7 � Handling and Storage

The precautions for safe handling and conditions for safe storage, including any incompatibilities, is retrievable from the OSHA Occupational Chemical Database, ToxNet HSDB, and NIOSH Pocket Guide to Chemical Hazards. Make sure to include information on whether a safety eye wash and/or shower is required when using this chemical.

Section 8 � Exposure Controls/Personal Protection

Include relevant exposure limits here. It is best practice to include the following for each chemical, as applicable:

This section should also include information if the chemical(s) is a carcinogen, and include engineering controls and personal protective equipment (PPE) for the anticipated routes of entry (eye/face protection, skin protection, respiratory protection).

Useful resources for determining the proper PPE are included below:

Section 9 � Physical and Chemical Properties

This should be present on the original material safety data sheet you are converting to SDS format. Alternatively, the information on each chemical(s) may be able to be obtained from the ToxNet HSDB and the International Chemical Safety Cards by the CDC. The International Chemical Safety Cards can be searched by CAS number, chemical name, RTECS number, and UN number.

Section 10 � Stability and Reactivity

Your research using the ToxNet HSDB, OSHA Occupational Chemical Database, and NIOSH Pocket Guide to Chemical Hazards will have identified the stability and reactivity of the chemical(s) you are researching.

Section 11 � Toxicological Information

Your research using the ToxNet HSDB and ATSDR Toxic Substances Portalwill have given you much of this information. Make sure to verify the carcinogenicity from ACGIH, International Agency for Research on Cancer (IARC), EPA Integrated Risk Information System, National Toxicology Program (NTP), and OSHA.

Section 12 � Ecological Information, Section 13 � Disposal Consideration, Section 14 � Transport Information, and Section 15 � Regulatory Information

These sections are not required by OSHA at this time; you can include the information or state �This section is not required according to 29 CFR 1910.1200(g)(2)� if your SDS is being developed for internal use only.

Section 16 � Other Information

This section can include the date of preparation of the last revision of the SDS, literature references and sources for data used to compile information for the SDS, a key for abbreviations, National Fire Protection Association (NFPA) and Hazardous Materials Information System (HMIS) ratings, and any internal �safety notices� or legalese you�re required to place at the end of every SDS by your corporate counsel.

Completion and Review

Request that a colleague review the SDS for typos and accuracy. Make sure the hazard statements and precautionary statements are correct for the hazard classification and associated category you have selected for the chemical(s) on the SDS. Double check CAS numbers and chemical concentrations.

Once the SDS revision is complete, if you have a need for facility-specific labels, this is a simple process. All the information you need for the label can be copy/pasted from the SDS to the label. The pictograms can be downloaded from OSHA�s Hazard Communication website for use in container labels. You�ll be surprised how much you�ll learn when completing the SDS revision.

Low odor does not mean low hazard - mastic removers in asbestos abatement

So, I recently completed a cursory review of several different low-odor mastic or adhesive removers that were proposed for use in an asbestos abatement project.

Like many safety professionals, I always specify "low odor" or "no odor" chemicals to be used, but I had not previously encountered the Safety Data Sheet (SDS) for most of the mastic removers that were proposed by the contractor. I'd heard anecdotal evidence that the soy-based mastic removers were less effective for asbestos abatement, but understood they were intended to be an environmentally-friendly option.

I was not surprised to find that most of the SDS were wholly unhelpful in assessing the hazards associated with the chemicals. Many of them were one page, in tiny font, and had not been converted to the new Globally Harmonized System for the Classification and Labelling of Chemicals - Safety Data Sheet required format yet.

Based on the lack of information, I threw together a table for each proposed chemical to evaluate them and did some preliminary research on the hazards of each mastic remover. 

The following mastic removers were evaluated:
This evaluation is provided below and should not be construed to be "official" occupational or environmental health guidance; readers are encouraged to do their own assessment and research to evaluate the hazards associated with these chemicals. Hopefully other safety and health professionals may find this useful in conducting asbestos project design activities when deciding which mastic remover should be used at an owner's site.

Also keep in mind that the hazard statements and precautionary statements were adapted from the manufacturer's existing language on the SDS. Too little data was present on the percent (%) of each chemical present to conduct a full Hazard Communication Standard Assessment and verify the needed pictograms or hazard classification.

Useful (and free!) training from FEMA for Industrial Hygienists and Occupational Safety Professionals

While preparing the syllabus and course content for my Spring 2014 course in "Emergency Preparedness and Pre-Planning" at Embry-Riddle Aeronautical University in Prescott, AZ, I developed a list of free training sources available on the Internet for my graduate students to use. 

Sometimes if I'm in need of a quick refresher, I turn to these sources for additional guidance. 

Today's list of courses is from the Federal Emergency Management Agency (FEMA). Their Independent Study Program will give you certificates of completion and even college credit if you need (and pay for) it. The courses are not just about emergency management and preparedness - they cover a range of topics, as you can see below.

Courses that an Industrial Hygienist or Occupational Safety and Health Professional may find useful:

IS-5.a: An Introduction to Hazardous Materials 


Many of these are on my "to do" list (once I have a little free time). According to FEMA's website, the listed courses will take anywhere from 1.5 to 10 hours to complete.

The next few posts will be on free training in mold, asbestos, lead, safety and health management, and other topics of interest to industrial hygiene and safety professionals. These free training courses won't "certify" you to do the work, just raise your awareness and understanding.
