Probably the last place you would want to find airborne polychlorinated biphenyl compounds (PCBs) is in your kitchen, yet that's exactly where scientists detected their presence, according to a new report in ACS’ journal Environmental Science & Technology. They say that the PCBs, which are widely considered carcinogenic, are unwanted byproducts of sealant breakdown in modern kitchen cabinetry.
As a group, PCBs are classified by the International Agency for Research on Cancer as known human carcinogens, and their manufacture was banned in the U.S. in 1979. But because of the tendency of these chemicals to stick around in the environment and their inadvertent production as manufacturing byproducts, PCBs can still be found in offices and schools. Keri C. Hornbuckle and colleagues at the University of Iowa College of Engineering wanted to determine how much and what types of PCBs are present in and around residences.
The researchers measured the concentrations of PCBs using polyurethane-equipped passive air samplers (PUF-PAS) for a 6-week interval from August 22, 2017, to October 2, 2017, inside and outside 16 homes in Iowa. They found neurotoxic PCB-47 and PCB-51, as well as PCB-68, at much higher levels than expected. The concentrations seemed to be dependent on the year the house was built, with higher levels in more recent years. After testing the emissions coming from a variety of household items, including the stove, floor and walls, the researchers found the PCBs wafting off the finished kitchen cabinetry. The researchers suspect that the substances come from the decomposition of 2,4-dichlorobenzoyl peroxide, a common ingredient in modern cabinet sealants. This finding brings to light a previously unknown source of a toxic chemical in the home.

Fifth Annual National Safety Stand-Down to Prevent Falls in Construction
The National Safety Stand-Down was created five years ago as a combined effort by OSHA, the National Institute for Occupational Safety and Health (NIOSH), and CPWR—The Center for Construction Research and Training, and other partners. For the past four years, the Stand-Down Campaign has had an impact on fall prevention and on the awareness and education of millions of workers in construction. Now in its fifth year, every participant can build on their strengths and welcome millions more to safety on the job. The National Safety Stand-Down will be held on May 7-9, 2018.
National Occupational Research Agenda for Musculoskeletal Health
The National Institute for Occupational Safety and Health (NIOSH) of the Centers for Disease Control and Prevention (CDC) announced the availability of the draft National Occupational Research Agenda (NORA) for Musculoskeletal Health for public comment. The agenda incorporates knowledge about injuries and illnesses, the state of the science, and the likelihood that new information and approaches will make a difference in preventing musculoskeletal disorders. The deadline to submit comments is May 21, 2018.
Tips for Tractor Trailer Safety
The dangers tractor trailer drivers face don’t end once they reach their destination. Whether at the warehouse, dock, or construction site, drivers are exposed to struck-by, crushed-between, and other safety hazards. OSHA is teaming with the trucking industry to raise awareness of these hazards, and help prevent serious and fatal injuries.
According to data from the Bureau of Labor Statistics, at least 96 fatalities in truck transportation occurred in Midwestern states from 2015 to 2017. Thirteen of those fatalities appeared to be related to coupling (attaching) and uncoupling (detaching) trucks from the rig.
OSHA and the trucking industry developed a new flier that addresses the three most common hazards: parking, backing up, and coupling and uncoupling vehicles:
Parking
- Park on level ground and close to the receiving door or site
- Set and test brakes
- Do not attempt to stop a rolling vehicle
- Place wheel chocks between the tandem wheels of the trailer
Backing Up
- Get Out And Look (GOAL)
- Use flashers, horn, and backup alarms
- Check both mirrors
- Roll down windows to hear
- Know the vehicle’s blind spots
- Use a spotter
- Back up slowly
- Stand clear when opening doors for unloading
Coupling and Uncoupling
- Only trained workers should perform this procedure
- Ensure stable footing when releasing the fifth wheel or adjusting tandems
- Wear bright visible clothing
- Set parking brakes and perform tug test
- Keep clear of tires and frames
- Check for vehicular traffic near you
