Hydrochloric acid health risks: vapor, mist, and fume inhalation
What is Hydrochloric Acid? Hydrochloric acid is a colorless, corrosive, liquid that fumes in air at high concentrations of 25% or more, and becomes a hydrogen chloride gas forming dense white vapors due to condensation with atmospheric moisture (Pubchem). The vapor is corrosive, and air concentrations above 5 ppm can cause irritation. Hydrogen chloride is… Learn More
A discussion on 3D printers, UFP emission, and HEPA filtration
Nowadays, it is a common sight to see 3D printers in homes, schools, offices, labs, and workshops. The ability to quickly and economically print objects and prototypes make 3D printing one of the fastest-growing technologies today. The process of creating three-dimensional printed objects is actually quite interesting. The majority of commercially available 3D printers… Learn More
OSHA releases final rule on respirable crystalline silica
Original regulation on occupational exposure to respirable crystalline silica – a known human carcinogen – had not been updated in over 40 years despite years of studies showing its debilitating and often fatal health effects on workers. In most recent years, the use of silica in the workplace has expanded across several new industries and… Learn More
University utilizes ductless containment hood for bone DNA extraction
Traditional DNA specimens gathered at crime and trauma scenes include hair, blood, saliva, and other bodily fluids. In most cases these are excellent sources for identifying human remains. Unfortunately, if a body is severely decomposed, exposed to extreme environmental conditions, or only skeletal remains are found, it makes recovering DNA that much more difficult. In… Learn More

Economical clean room hood for platelet-rich plasma injection preparation
According to The American Orthopaedic Foot and Ankle Society, platelet-rich plasma (PRP) is “a patient’s own concentrated platelets (that) contain a large number of growth factors.” Patients with ligament, cartilage, tendon, or bone injuries turn to PRP injections to help reduce pain and stimulate healing in the affected area(s). Since PRP injections utilize the patient’s… Learn More
