Controlling Indoor Air Quality in a Healthcare Facility

Each year in the United States, roughly 1.7 million people are effected by healthcare-associated infections (HAIs), resulting in an average of 99,000 deaths and $20 billion in hospital costs, according to the Centers for Disease Control and Prevention.

Most of the training for HAI prevention focuses on healthcare providers performing tasks in a sanitary way, however, the facility and its indoor air quality also play an important role.

Ignition Sources of Dust Explosions

OSHA reports that more than 3,500 combustible dust explosions have occurred over the last 28 years. In 280 major incidents, over 700 injuries and 119 deaths occurred.

Dust explosions occurs when a sufficient amount of dust particles (fuel) disperse in the air (oxygen) and become exposed to a certain temperature (heat) in a confide space. According to OSHA, these five factors (oxygen, heat, fuel, dispersion and confinement) are knows as the “Dust Explosion Pentagon.” All elements must be present for a combustible dust explosion to occur.

How-to Repair a Fire Damper

Fire dampers play a crucial role in the life safety and the HVAC systems in a facility. Fire damper maintenance ensures that the damper is working properly and would help prevent the spread of smoke and fire throughout a building in the event of a fire. It can be difficult to assure optimal performance of a fire and smoke damper due to the complex structure of the damper.

There are a variety of reasons a damper may fail an inspection. Some of the most common reasons a fire damper fails an inspection are listed below.

Combustible Dust: A microscopic hazard can cost your business millions

Businesses are always looking for ways to save money, especially millions of dollars. Did you know? Dust can cost your company millions of dollars – more specifically, an explosion from combustible dust. It is a hazard that often goes unnoticed until it’s too late. A combustible dust explosion typically destroys buildings beyond repair due to the amount of combustible particulates that accumulates on surfaces.

So what is combustible dust?

7 Industrial Elements That Cause Dust Explosions

There were more than 82 dust-related fires or explosions over the last decade, according to OSHA.

Organic, metallic and some nonmetal inorganic materials can cause a combustible dust explosion. Some materials, such as powdered metals or flour, are intentionally created to become powder, while other materials like synthetic fibers and paper, unintentionally generate dust.
