Hazardous Materials Communications Guidelines for Employers: OSHA Standards and Requirements

GHS HazCom Online Training

What Are Effective Dates for New HazCom Standard Changes Including the GHS?
1910.1200(j)(1) says;  Employers shall train employees regarding the new label elements and safety data sheets format by December 1, 2013.

What are your responsibilities as an employer?
Under the provisions of the Occupational Safety and Health Act of 1970 ( OSH Act), as the employer, you must provide a workplace free from recognized hazards that are causing, or are likely to cause, death or serious physical harm to your employees regardless of the size of your business. You must comply with OSHA standards and regulations under the OSH Act. You must also be familiar with those OSHA standards and regulations that apply to your workplace and make copies of them available to employees upon request.

"Employer” means a person engaged in a business affecting commerce who has employees, but does not include the United States or any State or political subdivision of a State or those covered by other standards.

Who Is Affected by Hazard Communication Rules?
The HazCom Standard applies to all businesses where hazardous chemicals are used in the workplace. In 1994 the top two most frequently cited OSHA citations involved the HazCom Standard, and often resulted in fines of more than $1,000 per violation.

What is a Hazardous Chemical?
OSHA defines a hazardous chemical as any liquid, solid, or gas that could present a physical or health hazard to an employee. Examples of hazardous chemicals include cleaning agents, degreasers, flammables, greases, paints, pesticides, aerosols and compressed gases.

Are Consumer Products Considered Hazardous Chemicals?
Many employers do not realize that many of the same products they use at home are considered by OSHA to be hazardous chemicals. Exemptions are made for consumer products, and two criteria must be met in order to qualify.

First, the product must be used in the same quantity and concentration as it would be at home.

Second, it must not be used with greater frequency or for longer durations than it would be at home.

For example, the average American does not buy a five-gallon bucket of degreaser, nor does the average American clean their bathroom twice a day.

If you use hazardous chemicals in the workplace and do not meet the criteria for exemption above, then the HazCom Standard applies to your business!

Who falls under OSHA act requirements?
The Occupational Safety and Health Act of 1970 (OSH Act), 29 USC 667, affects almost every private business in the United States and U.S. territories. The act is administered by the federal Department of Labor’s Occupational Safety and Health Administration (OSHA) or an OSHA-approved state program. The original goal of the legislation was to assure employees’ working conditions to be free from recognized hazards that cause or are likely to cause death or serious physical harm. The reach of its coverage is best seen by reviewing the few organizations that are exempt from the act’s applicability.

The Act does not cover:
Self-employed persons;

Farms which employ only immediate members of the farmer’s family;

Working conditions for which other federal agencies, operating under the authority of other federal laws, regulate worker safety. This category includes most working conditions in mining, nuclear energy and nuclear weapons manufacture, and many aspects of the transportation industries; and employees of state and local governments, unless they are in one of the states operating an OSHA-approved state plan.

Steps Necessary for Compliance
Now that you know whether the Hazard Communication Standard applies to you, you're probably wondering “What do I have to do?” The key to successful compliance is to be proactive. Don't wait for an accident to happen or for an OSHA inspection to begin thinking about Hazard Communication. The key is understanding what you must do in order to comply.

First, you must develop a written HazCom plan.

Second, you should be sure that your hazardous chemical inventory list is up to date and complete.

Third, make sure that all hazardous chemicals are properly labeled.

Fourth, you must have accessible Safety Data Sheets (SDS) for every chemical that is covered by the standard.

And finally, you must properly train your employees. It's important to understand that most HazCom citations involve the absence of compliance — for example, NOT having a written hazard communication program or NOT properly training your employees.

Again, the key to compliance is proactivity. The first step is to understand what is required of you, and the second is to take action. Develop your written plan.

Train your employees. Do these things now. True workplace safety is implemented long before accidents happen or OSHA pays a visit.

Why Does OSHA Enforce the Hazard Communication Standard?
The actual OSHA standard, 1910.1200(a)(1) says, The purpose of this section is to ensure that the hazards of all chemicals produced or imported are classified, and that information concerning the classified hazards is transmitted to employers and employees. The requirements of this section are intended to be consistent with the provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS), Revision 3. The transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, safety data sheets and employee training.

What Are Minimum Hazard Communication Training Requirements?
Employee Information and Training:

Employers shall provide employees with effective information and training on hazardous chemicals in their work area at the time of their initial assignment, and whenever a new chemical hazard the employees have not previously been trained about is introduced into their work area.

Information and training may be designed to cover categories of hazards (e.g., flammability, carcinogenicity) or specific chemicals. Chemical-specific information must always be available through labels and safety data sheets.

Also it should cover any operations in their work area where hazardous chemicals are present; and, the location and availability of the written hazard communication program, including the required list(s) of hazardous chemicals, and safety data sheets required by this section.

Employee training shall include at least:
Methods and observations that may be used to detect the presence or release of a hazardous chemical in the work area (such as monitoring conducted by the employer, continuous monitoring devices, visual appearance or odor of hazardous chemicals when being released, etc.); the physical, health, simple asphyxiation, combustible dust, and pyrophoric gas hazards, as well as hazards not otherwise classified, of the chemicals in the work area; the measures employees can take to protect themselves from these hazards, including specific procedures the employer has implemented to protect employees from exposure to hazardous chemicals, such as appropriate work practices, emergency procedures, and personal protective equipment to be used; and, the details of the hazard communication program developed by the employer, including an explanation of the labels received on shipped containers and the workplace labeling system used by their employer; the safety data sheet, including the order of information and how employees can obtain and use the appropriate hazard information.

Minnesota Light Rail Finds a Train Signals EMI Solution from LBA

Posted: 26 Jun 2013 02:26 PM PDT

Minneapolis Light Rail Train at Station

When officials in Minnesota were planning a new light rail system that would link Minneapolis and St. Paul, they found that multiple protective equipment enclosures were needed to hold EMI and radio frequency interference-sensitive train control, security, and signaling equipment at over 30 wayside equipment shelters along the route. The equipment in these shelters would manage the many critical control and safety systems along the new 11 mile route, including audio, video and telecom circuits.

A key Minnesota Light Rail contractor called on LBA to design appropriate EMI protective telecom equipment enclosures. LBA Group, Inc. Chief Technical Officer Dr. Chris Horne, PE led the effort and consulted closely with the rail project's electrical contractor, Aldridge Electric and a Chicago-based fabricator. LBA applied flexible, out-of-the-box engineering ingenuity to come up with a singular, standard design that could work in all wayside locations, enabling significant procurement cost savings, deployment efficiencies, and lifecycle maintenance savings.

The LBA RF enclosure design not only provided for protection of sensitive equipment from outside RF and electromagnetic interference sources, including the high voltage power lines suspended above the tracks; it also provided complete, rapid equipment accessibility.  This had presented a challenge as the protective enclosures would be mounted in confined spaces against walls. LBA solved this problem by designing a special EMI-compatible hinged rack inside the unique protective cabinets. It permitted easy access to both the front and back of the equipment for critical maintenance and repairs without compromising EMI protection. The end result was a very cost effective, convenient EMI protective enclosure that met mission critical specifications for all wayside control shelter locations.

LBA is currently supporting several light rail projects around the US in Positive Train Control interference, RF safety, and other EMI matters.Horne and LBA VP of Sales, Mike Britner traveled to Minneapolis-St. Paul in June to review the completed EMI protective enclosure installations. They toured the facilities with Aldridge Electric Senior Project Manager, Richard Krzysko. The entire rail system continues to undergo testing with public opening of the new Minneapolis Light Rail Central Corridor in 2014.

This Minnesota project is the latest example of LBA's services supporting various light rail projects around the US.  LBA engineering projects include interference and coverage control for Positive Train Control, RF safety, right-of-way tower compatibility and other EMI matters.

"As new rail lines in the US are built and older infrastructure is upgraded with wireless communication and Positive Train Control (PTC) systems, the potential for additional risks is elevated with radio frequency interference requiring careful analysis and mitigation to ensure electromagnetic compatibility," said Horne.

LBA is fully committed to producing solutions to mitigate PTC interference, manage RF safety and EMI issues related to the reliability and signal coverage along rail systems and rail right of ways.

New SafeOne® PRO Brings More Choices in Personal RF Monitors

Posted: 13 Jun 2013 08:23 AM PDT

LBA Technology has supplied hundreds of original SafeOne® RF monitors to the tower and communications industry. After refining this popular personal RF monitor, the rugged workhorse is available again in the form of a much improved model. LBA worked hard with its fabricators at COMM-Connect to improve what is now available as the LBA SafeOne® PRO – still at it original low price of $695!

The SafeOne® PRO joins the fieldSENSE ProHD™ in the LBA lineup of economical RF safety monitors. With RF safety such a critical issue, LBA is proud to offer a choice of these two units at a price that's so affordable that everyone on a team that could be at risk for RF exposure can have one.  This is a much more reliable option compared to each person being forced to share one expensive RF monitor or a company having to invest in units costing three or four times as much as a SafeOne® PRO or fieldSENSE ProHD™.

The fieldSENSE ProHD™ is an excellent and cost effective RF personal alarm choice for tower crews and others who specialize in cellular site installations. SafeOne®PRO is another option for those who also work around other systems like FM, TV, low band communications, and even radar. It offers a wide frequency alarm band. The SafeOne® PRO also shows both general public and occupational MPE exposures, useful for those monitoring both controlled and uncontrolled RF exposures

LBA now offers a choice in personal RF monitors:

safeone personal rf safety monitorfieldsense personal RF safety monitor meter

One key improvement to the new SafeOne® PRO is its extended battery life using regular alkaline batteries. The unit also includes a handy battery life indicator meter. Two AAA batteries can operate the SafeOne PRO® for more than 250 days.

The SafeOne® Pro is the size of a cell phone and weighs less than 3 ounces. LBA provides a heavy duty nylon protective case with a loop that can easily fit on any belt, but is also designed for tower climbers to attach to their climbing belt.  LBA adapted the SafeOne® PRO to sustain the rigors of tower climbing.  The unit has proven to be especially popular with those who work on and around towers and antennas. This makes the SafeOne® PRO that much more rugged and dependable for those who stay on the ground but work around potential RF hazards.

"The new SafeOne® Pro Personal RF Monitor is an important piece of personal protective equipment (PPE) that employers should make available to their employees for compliance with FCC, OSHA, and other safe workplace requirements," said Dr. Chris Horne, PE, LBA's Chief Technical Officer.

OHSA compliance is imperative for any company.  If there are potential on-the-job RF Safety Hazards for workers, then they should have access to a personal RF monitor and RF awareness training. The question then becomes which monitor is right for the job at hand?


What are the uses and benefits of the SafeOne® PRO and the fieldSENSE ProHD™?

SafeOne® PRO

  • General Purpose RF Technician and Tower Climber Use
  • Occupational and general public MPE monitoring
  • Complies 100% with OSHA, Canadian and most international RF personal monitor requirements
  • Wide Frequency Coverage, 10 – 10,000 MHz
    • Industrial RF, FM, TV, Two-way, SCADA
    •  Aircraft, Public Safety, Cellular, Radar, Microwave
    • Battery meter and 250 day battery life
    • Includes heavy duty kit

fieldSENSE ProHD™

  • Cellular Site Technician and Trade Use
  • Occupational MPE monitoring only
  • Complies 100% with OSHA, Canadian and most international RF personal monitor requirements
  • Specialized Frequency Coverage, 350 – 3000 MHz
    • All Cellular, PCS, LTE bands, UHF-TV, UHF communications
    • Additional LOTO monitor mode and hardware
    • Includes heavy duty kit

The convenient one button operation of these units means they are simple and intuitive. The SafeOne® PRO and the fieldSENSE ProHD™ provide both an audio and visual warning when the IEEE and ICNIRP limit is exceeded.  The included heavy duty kits by LBA feature rugged nylon padded pouches designed for rigger harnesses and work belts to keep the RF Personal Monitor safe and out of the way, and storage boxes when off-duty. Because battery exhaustion on a remote job could be inconvenient, the kits include backup heavy-duty batteries.

Thousands of these monitors from LBA are in use around the world by major companies and government entities such as the U.S. Forest Service, General Dynamics, and NSORO.  All of the major cell carriers, tower companies, and many contractors have them available for their workers. Depending on the nature of the job either the SafeOne® PRO or the fieldSENSE ProHD™ is a must-have piece of personal protective equipment.

Personal monitor availability

Tower crews often work under tight project deadlines and can't wait weeks to get site-required PPE. LBA keeps both monitors in stock, for immediate shipment anywhere in the world. Standard ground shipping in the US is even free!

LBA is also committed to supporting your monitors. All monitors are tracked by serial number and provided with a recommended recalibration date to assist you in management and OSHA compliance. RF monitors carry a one year guarantee and LBA maintains in-house test and calibration facilities for prompt turnaround of your recalibrations and service requirements.

Detailed specifications are available on line for the fieldSENSE ProHD™ and the SafeOne®PRO. For additional information, to place an order or to request a quote, contact LBA's Betty Perez at bperez@lbagroup.com, 252-757-0279.

“RESOLVED: OVER-THE-AIR BROADCASTING IS A DINOSAUR AND SHOULD BE ABOLISHED IMMEDIATELY” – Part I: A Tale of Two Network Models

Posted: 03 Jun 2013 08:38 AM PDT

The above looks like a question to be put before a college debating club for argument, but it's really also a topic that is current and highly relevant for us folks out in the real world.  And in fact the "debate" is already underway, and not just within the confines of a single debating hall.

The FCC has in mind making "a few minor changes" in the use of the RF spectrum.  Nothing really major of course, at least in their highly informed view.  The changes are merely just "some tiny first steps" that would eventually lead to the end of over-the-air television broadcasting.  And let's put some strong emphasis on the word "broadcasting;" this is an important concept.

The Commission has it in mind for the owners of current television broadcast (there's that word again!) licenses to relinquish (for cash payments) their existing rights to use the public's RF spectrum, and then for the FCC to re-sell the "liberated" spectrum to the wireless carriers.  In principle the carriers would use the newly purchased spectrum to expand the "broadband superhighway" in this country.  The FCC's unstated goal surely must be to boost the US from its currently "dominant" 26th place position in the world ranking of the quality of US citizens' Internet access (a national evaluation based upon both the channel bandwidth available for the end-user and the cost to the consumer for such access), thus perhaps boosting the US ranking all the way up to…… 20th place, worldwide.  Whoopee!

Space doesn't allow our waddling through the current spectrum shenanigans; the machinations are well documented in the industry press.

If matters flow on unchecked, certainly the curtain will ring down on over-the-air broadcast television within most of our lifetimes.  The slowly diminishing use of over-the-air television broadcast signals by the general public (caused, in part, by the public's abject ignorance that such access exists as a free service) has already somewhat damaged the economic value of a broadcasting license.  Thus current broadcasters have less incentive, even in the absence of the FCC's proposals, to maintain and to develop their RF spectrum holdings.  The future is not bright for broadcast television.

old radio–television console

The radio–television console was once the center of mass communications

Neither is it bright for radio.  Technological obsolescence and rapidly increasing metropolitan RF noise levels have hugely hurt AM radio.  FM radio, which is not troubled by these technological and noise problems, is in a little better economic shape but it faces a different long-term problem.  The public is no longer strongly dependent upon FM radio for delivery of its "songs."  (Perish if the public should ever focus on music more extensively-structured than just "songs," such as entire Broadway musicals, jazz sets, and even……. (oooooooh) …….symphonies and concerti!)  Other media now do the public's song-fetching chores, especially for our youth.  Some of the population already has little, if any, need for or use of "radio."

The Once and Future Story of Broadcasting

But before we blithely toss over-the-air broadcasting away, let's step back for a moment and see what we have, before it disappears.

Over-the-air broadcasting was originally developed and then flourished to meet a single need. That purpose was, first in the case of radio, to bring audio-based information in real time to a mass audience.  In the later case of television, it was both audio and visual information.  Prior to the establishment of these two modes, there was no mass audience, real-time information delivery system in the country. None!

At the junction of the nineteenth and twentieth centuries the telephone and the telegraph could bring real-time information to individuals, while newspapers and magazines could bring delayed information to the masses.  But no medium could do both.  Broadcast AM radio, when it emerged in the 1920s, began to knit together a dispersed, largely rural country with real-time, mass audience information delivery.

The inventors of over-the-air broadcasting had stumbled onto a technological gem, although they might not have realized it in their zeal to expand the new medium.  But the system that they invented was not modeled at all on the only telecommunications "networks" then known, the telephone and the telegraph.  Instead the first broadcasters departed on a different route.

As every telecommunications engineer instinctively recognizes, originally the telephone and to a lesser extent the telegraph networks used "point-to-point" network models in concept and operation.  By way of explanation, in using this kind of network the calling individual (with the aid of the wire carrier's employees) established a "circuit" through the network from himself to the receiving party.  This dedicated circuit was used only by the two parties that it connected, and other subscribers wishing to use the network had to establish their own separate and individual circuits along it.  (That requirement, of course, is no longer strictly true in modern telephone networks.)

"Broadcasting" (a term of agricultural origins, here meaning "to cast [information] broadly") from its very beginning was a complete break with the telephone network concept.  Broadcasting was established on "point-to-multipoint" network model, meaning that one transmitting party could be received by an uncountable number of receiving parties.  That is the brilliance of the concept.  Allow one high power AM broadcaster to use 10 kHz of the RF spectrum, and perhaps three million listeners to that 10 kHz band of signals will individually and simultaneously receive the information.

That point-to-multipoint model is highly efficient in its use of spectrum.  Instead of three million RF-based channels in a wireless point-to-point program distribution system, there is only one.  Switch the same network over to point-to-point, and those three million listeners, each with his own private "channel," would need a total of 30 MHz of radio spectrum.  Within the radius of its surface wave coverage, one AM station would use the entire available local spectrum, with no room for any other wireless Service.

Enter, Wireless Broadband and the "Demand Pit"

If point-to-point seems resource-wasteful for a mass, real time information distribution network, it's only because it is actually wasteful.  But that is just what the FCC is proposing to do: tear down the point-to-multipoint broadcasting model and devote the "reclaimed" spectrum to what is essentially a point-to-point wireless Internet service.

 

US Wireless Subscribers & Major Wireless Services Auctions

The FCC has used auctions to fuel the insatiable demand for broadband spectrum

That proposed reallocation would feed a bottomless "demand pit."  There will never be enough RF spectrum to house the exponentially-increasing Internet demand!  Rational engineers would never endorse the notion of creating point-to-point mass distribution networks on the RF spectrum.  The FCC, however, apparently thinks the idea is "the greatest thing since sliced Coors in cans!"

Naturally, a greater number of individual point-to-point channels to serve an increasing number of end-user terminals require more operating bandwidth.  If the increasing bandwidth requirements can be satisfied through the establishment of terrestrial copper- or glass-based distribution networks, the demand can (theoretically) be satisfied.  More "wire" can be pulled in to supply the additional capacity.  If instead the increasing demand is pushed onto the RF spectrum……..well, the supply of usable spectrum obviously is tightly constrained.

This is the rationale for the contention that the FCC's "notion" of pushing the expansion of the national "broadband highway" onto the RF spectrum is an exceptionally bad one:  it cannot permanently satisfy the ever-increasing bandwidth demand, while simultaneously it begins to squeeze out existing information delivery systems that are vastly more spectrum-efficient and -conservative (i.e., broadcasting) as well as other spectrum-requiring telecommunications applications, such as Public Safety.

Is There Hope for Broadcasting – Where Now?

With this brief foray into "message delivery network models" we have hopefully developed a little appreciation for the need to retain over-the-air "broadcasting" as a central part of the nation's mass audience message delivery infrastructure.  In the next several parts we'll look just a bit at the current "bandwidth" supply conundrum that is causing the squeeze on wireless broadcast spectrum, and then turn to suggestions for the revitalization of broadcasting to bring it back into its central (historical) position in the information-delivery systems pantheon.
