Failure to Manage Environmental Factors Contribute to Asthma Symptoms & Severity


Despite improvements made to air quality by restricting, refining incineration, and reclaiming heavy metals like mercury, Asthma has doubled in the last decade.  Last year, 4000 people have died and 1.8 million required trips to the Emergency Department.  Still, for a variety of reasons, the environmental controls component of asthma management guidelines tend to be less well understood and less effectively managed or implemented by health practitioners than the other components. In recent years, the National Institutes of Health and others have funded robust research on the effectiveness of environmental interventions, demonstrating substantial positive impacts on symptoms, quality of life, and utilization of health.  For thousands of people with Asthma, including those whose asthma is in relative good control, this new information holds great promise.

Two key air pollutants can affect asthma.  One is Ozone (found in smog). The other is particle pollution (found in haze, smoke and dust.)  When ozone and particle pollution are in the air, adults and children with asthma are more likely to have symptoms.  Ozone is often worst on a hot summer day, especially in the afternoons and early evenings.  Particle pollution can be bad any time of year, even in winter.

There are many sources of indoor air pollution in any home. These include combustion sources such as oil, gas, kerosene, coal, wood, and tobacco products; building materials and furnishings as diverse as deteriorated, asbestos-containing insulation, wet or damp carpet, and cabinetry or furniture made of certain pressed wood products; products for household cleaning and maintenance, personal care, or hobbies; central heating and cooling systems and humidification devices; and outdoor sources such as radon, pesticides, and outdoor air pollution.

May is Asthma Awareness Month. To learn more about effectively reducing the risks from air pollution, go to http://www.epa.gov/gateway/learn/airpollution.html

Tech Corner: Know your hazardous waste accumulation & storage rules

Image
One notable change triggered by the Hazardous Waste Generator Improvement rule is the marking and label requirements on hazardous waste accumulation containers while in satellite waste accumulation and in central waste storage.   Previous RCRA labeling regulations did not require generators to identify and indicate the specific hazards of the hazardous waste accumulated in containers, tanks, drip pads and containment buildings.   This resulted in a failure to communicate risks associated with wastes being accumulated or stored in different locations. Another risk associated with marking and labels was the Treatment Storage Disposal Facility (TSDF) not knowing how to treat the waste to meet land disposal restriction requirements because generators did not always identify the specific RCRA waste codes associated with the waste. To avoid these risks the following changes to hazardous waste management regulations have been applied: 1.        Satellite accumulation – Containers and

HWGI rule - Summary of important points

The Environmental Protection Agency’s (EPA) Hazardous Waste Generator Improvement (HWGI) rule has been in effect since May 30, 2017.  Regardless of generator status designation, there are some important tasks generators must complete.  Here is a summary of the most important of those requirements. ·         Episodic events – Generators can exceed their designated generator status threshold once per year.  Additionally, they can petition for an additional “unplanned” event within the same year.  Generators must have an EPA ID and advise the EPA at least 30 days prior to the event.  In the case of an “unplanned” emergency, the generator must advise the EPA with 72 hours. (§262 subpart L ) ·         Re-notification – SQGs are required to re-notify of waste activities using Form 8700-12 every four years starting in 2021.  LQGs continue current system of re-notification as part of its biennial reporting requirement. (§262.18(d) ) ·         Pre-transport marking & labeling – Gener

Tech Corner: More states institute COVID-19 Standards

Image
  Credit: Simon Davis/DFID 14 states have instituted COVID-19 safety standards for the work place so far. As the COVID-19 pandemic continues to surge in the US, the concern for worker safety and health has all but subsided and the need to institute COVID-19 safety standards has become very apparent. In the absence of federal leadership in establishing these standards, some governors and state health departments have stepped up to expand worker protections. Virginia was the first state to issue an Emergency Temporary Standard to protect workers during the COVID-19 pandemic along with Oregon and Michigan shortly following. Other states have issued guidelines, some of which are tied to enforcement efforts. Additional some cites also have issued ordinances geared toward protecting their local workers. Below is partial list of states along the Mid-Atlantic and Northeastern regions that have adopted COVID-19 safety standards (with links to more information) Massachusetts - Safety standards f
