According to the CDC, poison ivy is a common poisonous plant found throughout the United States. It can be found in forests, swamplands, roadsides, backyards and even in urban environments. That means, wherever you are, poison ivy could be right there!  And, it’s not always easy to spot.  When trying to identify this plant, consider the species, the season and your geographical location as the physical characteristics can vary. Being able to recognize local varieties, especially at a work site, is your key to avoiding exposure.

Poison ivy produces a liquid called urushiol, this is the so called “active ingredient” that causes the itching, blisters and rashes in most people who touch it. Outdoor workers can be exposed to poison ivy in multiple ways:

• Physical contact with the plant (including the roots!)


• Touching tools, equipment or livestock that have been in contact with the plant


• Inhaled aerosolized particles from burning the plant.

Recognition

Your ability to recognize poison ivy is the first step in preventing exposure. Depending upon where you live and the season, the plant can vary widely. It always has three leaves (like many other plants) but the size, shape and coloring may fool you. The following links provide some pictures and other useful information to help you identify the poison ivy lurking in your work place:

• USDA Invasive and Noxious Plants Guide


• Poison Ivy Guide


• USDA Federal and State Noxious Weed Guide


• Great Plains Nature Center

Prevention

When working in areas infested with this wicked plant, personal protective equipment (PPE) like gloves and boots, long sleeve shirts and long pants tucked into boots will help. Be extra careful to not touch the exposed clothing when removing it and wash it in the hottest water possible using copious amounts of soap and water with lots of room to agitate. If you’re not sure – wash it again as you can get a rash from clothing or tools that have the urushiol resin from even years back!

Always wash your skin with plenty of soap and cold water after exposure. (Hot water opens your pores and lets the resin absorb into your skin.) If you can get scrubbing within ten minutes of contact, you may have dodged the poison ivy bullet! And, always clean all tools and equipment that come in contact with the plant with soap, water and a bleach solution to avoid re-exposure.

Follow comprehensive decontamination methods – treat the urushiol resin as a chemical contaminant!

First Aid

How do you know you have poison ivy? Advice from the Mayo Clinic includes

Signs and symptoms of a poison ivy rash include:

• Redness


• Itching


• Swelling


• Blisters

Often, the rash looks like a straight line because of the way the plant brushes against the skin. But if you come into contact with a piece of clothing or pet fur that has urushiol on it, the rash may be more spread out.  The reaction usually develops 12 to 48 hours after exposure and can last up to eight weeks. The severity of the rash is dependent on the amount of urushiol that gets on your skin.

Once you know you’re exposed, wash exposed skin with plenty of soap and cold water to break down and encapsulate the oil. Web MD advises these additional steps:

An alternative is rubbing alcohol, which can dissolve and remove the oils from your skin. If you can remove the oil within 10 minutes, you are unlikely to develop the rash. Symptoms from a mild rash can sometimes be relieved by the following:

• Cool compresses with water or milk


• Calamine - A nonprescription lotion


• Aveeno oatmeal bath - A product you put in the bath to relieve itching

And, of course, if the reaction seems to be severe, is spreading or lasting longer than a few weeks, ask for immediate professional medical attention.

Three leaves? Be cautious!

At Emilcott, we frequently run into job sites with high potential for poison ivy exposure…think about the uncleared, overgrown or unkempt places that surveyers, highway workers, laborers, HazWOPER workers, engineers, inspectors,  construction workers, and landscapers, often find themselves! And don’t think that you’re immune either. My coworker, Paula Kaufmann, CIH, wrote about her overconfidence that she had not been sensitized to urushiol (and thought she was “immune” and her inevitable reaction to repeated exposure. Maybe she should have paid attention to Emilcott’s poison ivy awareness and other outdoor hazards that is a part of many of our health and safety training courses!

Have you had an experience with poison ivy on the job? Were you prepared ahead of time? If not, what happened?

As an occupational and safety professional, I’ve noticed that the Occupational Safety and Health Administration (OSHA) has been busy over the last few weeks!  The following is a summary of highlights of interest to Emilcott clients.  Did any of these catch your attention?

Highlight #1: Up-to-Date OSHA Standards

Announcement of a final rule to help keep OSHA standards up-to-date and better enable employers to comply with their regulatory obligation. The concept should allow OSHA to easily remove outdated requirements, streamline and simplify standards without reducing employee protection. The rule is to be published soon in the Federal Register:  OSHA Standards Improvement Project-Phase III final rule.

Benefit to employers:  OSHA estimates that the final rule will result in annual cost savings to employers exceeding $43 million. Now that’s an improvement to cheer about!

In the news release, OSHA stated that there will not be any NEW requirements set by this rule, so employers will be able to comply with it immediately. (However, it seems that there will be modifications...Emilcott will be keeping a lookout for those and post an update below or as a new EHSWire post.)  Here are some examples listed in the news release on this rule:

• Respiratory Protection
  
  
  
  • Aligning air cylinder testing requirements for self-contained breathing apparatuses with U.S. Department of Transportation regulations
  
  
  • Clarifying that the provisions of Appendix D, which contains information for employees using respirators when not required under the standard, are mandatory if the employee chooses to use a respirator.
  
  
  
  


• Sanitation
  
  
  
  • Defining “potable water” to meet the current Environmental Protection Agency
  
  
  
  


• Access to Exposure and Medical Records
  
  
  
  • Deleting a number of requirements for employers to transmit exposure and medical records to NIOSH
  
  
  
  


• Slings
  
  
  
  • Requiring that employers use only slings marked with manufacturers' loading information
  
  
  
  

Highlight #2: OSHA Injury and Illness Logs - Musculoskeletal Disorders (“MSD”)

Reopening the public record on proposed record-keeping rule to add work-related musculoskeletal disorders column.  This keeps popping up!

• In January of  2010, OSHA proposed to revise its Occupational Injury and Illness Recording and Reporting Requirements regulation to restore a column to the OSHA 300 log that employers would have to check if an incident they already have recorded under existing rules is an MSD.  


• On January 25, 2011, OSHA withdrew this proposed revision.


• On May 17, 2011, OSHA reopens the public record on a proposed rule.

Highlight #3: A Survey of Private Sector Employees

Launch of a targeted employer survey to collect information that would improve the development of future rules, compliance assistance and outreach efforts.

• The survey will be sent to private sector employers of all sizes and across all industries under OSHA's jurisdiction. Questions include whether respondents already have a safety management system, whether they perform annual inspections, who manages safety at their establishments and what kinds of hazards they encounter at their facilities. Participation in the survey is voluntary.

Highlight #4: Fall Protection for Residential Construction Workers

Online presentation about fall protection specifically designed for residential construction workers. (This is really great as residential construction crews frequently overlook safety – just look at all the roofers walking around the top of your neighborhood homes!)

• The presentation describes safety methods for preventing injuries and deaths from falls, and explains techniques currently used by employers during various stages of construction. These techniques involve the use of conventional fall protection systems including safety nets, guardrails, and personal fall arrest systems such as body harnesses, lanyards and lifelines.


• The presentation is among a series of guidance materials on OSHA's Residential Fall Protection Web page.

On a personal note, my son is currently volunteering as a roofer on a Habitat for Humanity home construction site … he informs me that he is wearing fall protection and the roof has anchor points! 

So, can you tell that Emilcott is pretty excited about these changes? Instead of putting the onus on employers to become more aware of OSHA, OSHA is streamlining existing rules to match other government agencies (radical!), listening to employers before leaping into new regulations, and looking at alternative messaging techniques to market segments that frequently fall in the cracks.

If you’re interested in what’s happening at OSHA, just take a look at the loooooong list of May press releases…Are there any highlights that you think important to you or American businesses? Any predictions for June?

As a resident of New Jersey, I have noticed more ticks this spring than I can personally remember in the past few years. Maybe it’s because I have been in the field more (I’m a Professional Land Surveyor) or my dog is covering more acreage in the woods. At work, in the field (literally FIELDS), I am more apt to be using white Tyvek with built-in booties to keep as many ticks off of me as possible; when I am at home I like wearing light colored clothes with my pants tucked into my socks. Folks in my company spray their clothes with Permanone, a Permethrin-based tick repellent and insecticide. This and a lot more information about keeping ticks off of you and inspecting for them is in the CDC’s “ Tick Management Handbook.” What scares me the most are the ticks that I don’t find, not the ones I do find. My life seems like one endless tick check!

Many of you already know my experiences with Lyme disease and have a seen  how Lyme has affected our family. Based on my own experiences, I tell anyone who ever has any symptoms of Lyme to get to a Lyme and vector borne disease specialist immediately.

I recently had a huge surprise; one of my children who has been treated for Lyme three times over twelve years, after spending the past year seeing many different kinds of specialists to figure out what was causing her nausea, fatigue and headaches, was diagnosed with Lyme again (or is it still?) by a Lyme and vector-borne disease specialist. Other types of doctors did not identify the source of her ailments. Once again I have seen the value of spending out of pocket money on expert and specialized doctors when my insurance company and general practitioners has told us something else.

Be aware; know the symptoms of Lyme and co-infectors. Pay attention daily to the health and behaviors of your coworkers, family and friends!  Do not let money be a barrier to getting to the appropriate diagnosis and treatment

For more information on protecting yourself from Lyme disease and understanding the symptoms to get the correct treatment, I recommend the following resources (shown here in alphabetical order):

• American Lyme Disease Foundation


• Columbia University Medical Center - The Lyme and Tick-borne Diseases Research Center


• IGeneX, Inc. - A specialty immunology laboratory and research facility


• International Lyme and Associated Diseases Society


• Lyme Disease Association, Inc

Has anyone ever asked you why OSHA requires extensive procedure and safety control training for crane operators and assistants?  What about why is it really necessary to take time to provide crane safety awareness training to workers working “around cranes” even though it is not required by OSHA? Well, READ THESE recent news headlines (and follow the links for more information)!

In 2010, 782,000 students nationwide attended OSHA Outreach Training courses with an 11% increase in students attending the 10-hr Construction Industry Training -- the highest attendance of all courses offered. What is the driving force for the high and rising class attendance? Bids for construction projects with both public and private funding now require that employees of contracting companies complete and pass the OSHA Outreach in Construction courses to reduce project liability and cost. 

What is Construction Industry Outreach Training?

The OSHA Outreach Training Program for the Construction Industry teaches construction workers  how to identify safety and health hazards and how to avoid and prevent these hazards and injuries with the “ Focus Four Hazards” of falls, caught-in or between, struck-by, and electrocution. The training also covers workers’ rights to a safe workplace, employer responsibilities, and how to file a complaint to OSHA. The Standards applicable to the Construction Industry are contained in Section 29 of the Code of Regulations, Part 1926. 

Who Should Attend a 10-hour Construction Industry Training Course?

Workers must complete the OSHA 10-hr Construction Industry Training Course to work on any publicly-funded construction project in Connecticut, Massachusetts, Missouri, Nevada, New Hampshire, New York, and Rhode Island.  Nevada also requires those with supervisory or safety responsibilities complete the 30-hr course.

Many private companies are adding this training to their bid requirements as well! Why?  This course is an excellent introduction to health and safety programs for workers new to construction or when it is time to create a paradigm shift in attitudes about safety. Although the OSHA 10-hour Construction Industry course is designed for entry-level construction workers, many organizations include ALL their site personnel in this training because EVERYONE is responsible for safety.

OSHA, government and private contractors, and insurance providers recognize the completion card as an indication of the importance of safety and health for both the individual and the organization.  In fact, Workers’ Compensation insurance providers often will reduce rates for companies that recognize training as part of their Health and Safety Program and include this essential training to their staff.

Emilcott’s OSHA 10-Hour Construction Industry Course

Based on the requirements established by OSHA, Emilcott’s 10-hour Construction course provides important information about the recognition, avoidance, abatement, and prevention of safety and health hazards in workplaces in the construction industry. This training assumes no prior training nor requires any prerequisite training.  Much of the Emilcott Training Institute’s 10-hr Construction Industry course is interactive and hands-on to ensure that key health and safety concepts are retained .  More importantly,  our courses are taught by instructors with real-world experience. Credentials and certifications provide a way to verify competency in particular fields but real-world experience should not be discounted. It’s one thing to talk about trenching hazards, it’s quite another to actually work around them. This experience allows Emilcott trainers to put the material in perspective and help students make the connection between theory and practice.

Quality Training Makes a Difference

With twenty-five years of consulting experience with all types of companies, projects, work sites and hazards, we universally find that the  OSHA Outreach Courses for both Construction and General Industry help everyone at the site “get it” when it comes to site safety!  When part of an implemented Health and Safety Plan, the education provided by quality OSHA Outreach courses has helped our clients reduce their accident incident rates AND insurance rates! 

Do you have examples of the OSHA Outreach Training raising the bar of safety at your site? Is there something you’ve learned in an OSHA Outreach Training Course (Construction or General Industry) that has helped you on the job?

On April 15, OSHA announced revisions to the Outreach Training Programs as part of a continuous improvement program. Effective immediately, these new requirements apply to both the trainers and training materials.  The Assistant Secretary of Labor for OSHA, Dr. David Michaels, explained the announcement by stating, " These revisions will serve to tighten the program controls to ensure the best training is provided to the worker participants. Trainer reliability will be enhanced and classes will focus more on fulfilling students' needs for safety and health training."

Here is a snapshot of the revisions:

• The "program guidelines" are now defined as “program requirements" (translation: must be done).


• Separate procedures are provided for each of the Outreach Training Programs, Construction, General Industry, Maritime, and Disaster Site Worker. 


• A trainer Code of Conduct and a Statement of Compliance requires each trainer to verify that the training they conduct will be in accordance with the Outreach Training Program requirements and procedures.


• Classroom size is now limited to a maximum of 40 students.


• Only translators with safety and health experience can be used.


• Videos can be used for only 25 percent of the training period.


• OSHA course completion cards must be provided directly to the students within 90 days of class completion.


• All construction classes are required to include four hours on Focus Four Hazards.


• All 30-hour classes must include two hours on Managing Safety and Health.


• The new requirements and procedures also integrate recent requirements which require training classes to last a maximum of 7½ hours per day and include a new two-hour Introduction to OSHA training module.

The effect of these changes is higher quality OSHA training offered by authorized training groups because, in theory, a better trained worker is a safer worker. As you reviewed the changes to the training program and trainers, what do you think the effect will be? Do you think that the revisions will improve worker safety or are just another paperwork high jump for employers and training institutions?

In an age where we are reliant on modern technology as a part of our job, it is difficult to imagine not being able to use your cell phone or access the Internet because of topography.  As the Field Safety Manager for a 300-mile electric power transmission power line construction project, one of my first tasks was to address the question “How do you make communication possible across 275 miles of relatively unpopulated, harsh mountainous territory”?  Specifically, I had to meet OSHA’s requirements for communication:  29 CFR 1926.35 “Employee Emergency Action Plans” and 29 CFR 1926.50 “Medical Services and First Aid”.  

For a project health and safety administrator, it is vital to be able to communicate with your team members and with outside resources. How do you keep tabs on who is where and what is happening? How do you find if something has gone wrong or someone needs help?  In fact, these are the reasons that OSHA implemented the Standards listed above – life and death situations may depend upon it!

On this particular project, numerous construction crews were working at different, extremely remote locations with a distance of several miles between each work crew. While the power line tower construction and electric line-stringing companies included requirements for an eventual end-to-end 2-way radio system, the system was not available for at least the first year of the project. And, since cell phones and the average two-way radio systems were not able to be consistently or reliably available to meet the communication needs required for this project, I needed to find an alternative. 

After digging around and countless meetings, calls, and trips to all kinds of communications companies, we settled on a resourceful, cost-conscious and effective method of communicating between the crews, safety personnel, surveyors and managers. The end result was a creative mix of new technologies:

• Cell phone signal boosters in each vehicle in the field


• GPS SPOT locator units for each  crew


• New technology satellite phones for work crews heading into the most remote locations.  

The vendor that built these systems also owned many of the frequencies needed for an end-to-end two-way radio system that would reach across the 275-mile project location.

Of course, the system’s effectiveness had to be proven – we were relying on it! So, I spent hours deep in the mountains field testing the equipment in some of the most remote project locations I have ever seen. Luckily, I was helped by some of the project team members who had spent a great deal of time in this area. Experience also helps communication!

This project had unusual difficulties – a big, remote, mountainous and unpopulated area – that could have thwarted OSHA’s communication requirements.  At any time, it would have been easy to throw in the towel, cross our fingers or perhaps put together a patched-together system and hope it worked.  However, with some tenacious ingenuity and a confidence that a reliable health and safety communication system could be found, we were able to overcome the almost overwhelming challenges and put an effective field communication system into place.

Have you been faced with challenges to provide adequate communication systems for your employees?  What has made a job site seem almost impossible to conquer? What did you do to overcome those challenges?

I have been doing on-site environmental health and safety (EHS) work at many types of outdoor job sites for six years.  A big part of the site safety manager at a construction project is air monitoring. When workers have the possibility of exposure to an airborne hazard, it's critical to take frequent measurements of site conditions (often airborne particulates or hydrocarbons) to define worker risk for exposure. When the risk increases, the safety plan kicks in to prevent overexposure. Knowing what is floating in the air at the job site (and how much of it) is why air monitoring is such an important part of any construction site safety program.

For the last several months I have been working at a former Manufactured Gas Plant (MGP) responsible for, yet again, another air monitoring program.  The difference is, for the first time, I’m using the Greenlight Environmental Monitoring System for air monitoring – a completely new experience.   

How I Used to do Air Monitoring

Maybe this daily process looks familiar to you? Snow, rain, ice, cold…the daily routine didn’t vary much!

• I collected the air monitoring instruments at the end of the day and downloaded each one individually to get the day’s readings.

• I checked through the day’s data to see if there were any problems (maybe a little late?).

A real leap in monitoring technology meant that I was using a laptop for data collection!  I drove or walked to each field station to download data onto the computer. Sunny days, while pleasant, had their own challenges – have you ever tried to look at a laptop screen while combating the glare of full sun? Needless to say, when it came to technology I was open…but skeptical.

My New Perspective

The differences between the fairly standard monitoring equipment setup (even with the laptop addition) and how the Greenlight System works is like night and day. As I worked, my initial impressions were shaped by Greenlight’s ease of setup and operation as the entire system design has been set up from an EHS professional’s perspective:

• All monitoring devices in the field are turned on and off from a central location.


• No tedious end-of-the-day drive and download because the System continuously feeds and records monitoring data to a server in “real time”.  

From the minute the project starts up each day, the monitoring results are displayed in REAL TIME on my operator screen.  I can see ALL of the readings from the entire site’s monitoring stations at the same time, no matter where they are in the field!  In fact, now I see site conditions as they happen so that I can take action as needed. And, if a field station or monitoring device is non-responsive, I am notified almost immediately rather than discovering that there’s no valid data to download at the end of the day.

The Greenlight System that I’m using includes what I consider to be ever-important – a weather station:  temperature, humidity, wind speed, and wind direction. Having this information corresponding to particulate or hydrocarbon monitoring -- in real time -- is critical when trying to define potential exposures to hazardous materials and implement appropriate controls. Since weather conditions directly affect air monitoring and have a potential to change quickly (and sometimes without much warning), the data pouring in from the weather station is very useful to have at my fingertips.

The Learning Curve Levels Out

Since I am a new operator of the Greenlight System, it has been a learning process for me. Starting out was a little bit scary! After six years of doing it pretty much one way, it’s a new way of both thinking and reacting. But, the ease of operation and the effectiveness of the System have transformed me…allowing me to provide more effective support to the site construction team. 

• Need the entire site air monitoring and weather condition information? With the data on my computer screen and on the server, if anyone needs a snapshot of site conditions at any moment, I can supply that information.


• Want to know what happened last week? I’ve got it the information all ready to go! It no longer takes hours or days to find the right data and put it into a format that is understandable and explainable.


• Concerned that there is a change in airborne contaminant levels at the site?  I’m on top of that, too! Even when a small change occurs, I am notified immediately, and I can quickly investigate. 

The Data Speaks

My sense is that when the construction team experiences how available the air monitoring data is and that with these data we can be very responsive with control implementation, they are more confident that are working in a safe environment.  The workers seem more content, and project managers are pretty happy knowing that they can continue working safely while staying on time and on budget.

What new innovations do you see in particulate and hydrocarbon monitoring at construction sites? Have you found any other tools that will help you be a more effective site safety manager? What other “tools” would you like that would help you monitor airborne contaminants?

We all know what Green Buildings are, right? There are various permutations but generally, to be green, the structure is designed, built, maintained and sustained in an environmentally responsible and resource-efficient manner. The end-all objective is to reduce impact of the “built package and system” on both the environment and mankind by

• Using energy, water, and other resources efficiently


• Protecting occupant health


• Improving employee productivity


• Reducing pollution and waste

As a LEED AP-certified professional who specializes in Indoor Environmental issues with a focus on fire and life safety, I was very interested in recent articles that are creating awareness of some critical health and safety problems inherent to the green building movement that 1) use innovative, locally-produced products, and 2) implement new design, construction, and operation approaches intended to reduce energy usage and be environmentally sound.

Green Building Fire Safety

In Megan Grennille’s recent EHSWire article about the seminal Triangle Fire, it noted that building and fire code rules caught up with the high rise construction only after the tragedy of 146 worker deaths highlighted the challenges of safety and rescue in the case of a fire. The same situation recently occurred in Bakersfield where a green-constructed Target store highlighted some new concerns for health and safety for emergency responders:

“The fire at the Bakersfield Target started, firefighters learned, at the photovoltaic array [solar] on the building's roof. Even after the firefighters disconnected the electrical mains, they discovered that the solar panels were still energized, presenting a safety challenge in addition to the fire.”

This brings to light how the integration of green building practices on a seemingly typical commercial building can present new hazards that must be identified to protect building occupants and emergency responders.  Fire fighters responding to an alarm may cut electrical power from the supply grid, but what is the procedure if there is an active solar array or an integrated wind turbine generating power as a part of the building?  Other “new” electrical and fire hazards facing unprepared emergency responders include the unknown level of fire resistance of recycled/green building materials, how to control fire spread on green vegetative roofs, and how to control smoke in wide, open atrium areas.

“ owners of green buildings might have to be aware that the green designs can present previously unconsidered challenges that arise as a direct result of construction choices. ...Because codes — even a decade after green design concepts hit the mainstream — still largely deal with traditional building designs and materials, facility managers have to know how to address the intersection of green design and current codes.”

The bottom line is that "green concepts should be reviewed as part of a fire-protection and life-safety analysis”, because buildings, green or not, must meet building and fire code standards to protect the health and safety of both the occupants and emergency responders.

Moisture and Mold Management in Green Buildings

Another potential hazard of green buildings is the management of moisture within the building and how selection of a green design and materials may be inappropriate if the location and weather are not considered:  “the design-and-construction community must not assume that if one builds green, then one will be building regionally correct or even lower risk buildings”.

A recent article, Hidden Risks of Green Buildings, was written from an insurance underwriter’s perspective and centered on the management of moisture.  The article mentioned the trend of using carbohydrate-based building products instead of petroleum-based building products.  That is where my eyes widened! Any indoor quality consultant knows the formula:  moisture + food source = perfect habitat for mold growth.  Carbohydrate-based building products are food for mold!

Moisture comes from many sources in a building: bulk water from a rook, window, or facade leak; water pipe break; HVAC condensate overflow; condensation on cold surfaces; or vapor (relative humidity) in the air.  Additional humidity can be added to the air by introducing humid outdoor air that has not been properly dehumidified or from other sources such as showers, locker rooms, steam rooms, gyms, kitchen facilities, human respiration (particularly if more people are occupying the space than the original design).  ( More information on these moisture-related potential problems including the risk of LEED “flush-outs” can be found here.)

Moisture meeting carbohydrate-based building materials over time certainly does look like the potential beginning of The Perfect Storm, because, in reality, carbohydrate-based building materials, even treated with the best biocide, would only be “mold resistant” not “mold proof”.  Given food, water, and time… mold will grow.  So as a professional IEQ consultant who has seen it all when it comes to mold contamination, I sincerely believe the article’s foreshadowing that “ the design community would be advised to prioritize the lessons…already learned from the waterproofing, humidity control, and building forensics community”.  When using potential mold “food” within a building, moisture control is ever more critical to the air quality of the building as well as the building material’s life cycle.

Are you interested in green construction? Have you thought of the potential hazards that can be created when using new technologies, new materials and tightening up the envelope?
