Introduction: Restrained subjects often spit on law enforcement and corrections officers and medical responders. Based on the droplet-transmitted risk of COVID-19, such spitting could be considered a potentially life-threatening assault. Officers commonly use "spit socks" over the head and neck of spitting subjects to reduce this risk. The pneumatic impedance of such socks has not been published, so this remains an open issue for arrest-related death investigation.
Methods: We purchased samples of 3 popular spit sock models, 3 insect-protecting "bug" socks and hats, 3 N95 masks, a standard 3-ply surgical mask, and a common dust mask. We used a BTmeter model BTN8468 digital anemometer, an HTI model HT-1890 digital manometer, and an AC Infinity Cloudline model S6 inline controllable fan to measure air flow versus pressure drop. We compared the curves graphically and also calculated a pneumatic pseudo-impedance by dividing the pressure drop by the air velocity.
Results: The spit and bug socks allowed nearly maximum airflow with minimal pressure (≤1 mm Hg), whereas none of the masks allowed greater than 2 m/s of airflow at maximum pressure of 3 mm Hg. All of the spit and bug masks were grouped together with the lowest pneumatic impedances, whereas all of the N95 masks were grouped together with the highest values. The dust mask and surgical mask were in between with the dust mask closer to the spit and bug masks, whereas the surgical mask was closer to the N95 masks in impedance.
Conclusions: Commonly used spit socks offer nearly zero resistance to breathing. The highest resistance spit sock was still 100 times better than the best N95 mask for airflow during inhalation. Our results do not support the occasional hypothesis that spit socks might contribute to an arrest-related death.

Experiencing side effects when wearing N95/P2 masks has negative impacts on health workers and increases exposure to pathogens. While side effects of wearing P2/N95 masks have been reported previously, these masks have never been used as widely as during the COVID-19 pandemic. This study examines Australian hospital nurses' experiences and perceptions of P2/N95 mask usage and its impacts on patient care at a time when P2/N95 masks were widely used.

Flooding events, particularly those caused by hurricanes and other large storm events, are increasingly fueled by climate change. Stormwater intrusion into homes creates ideal conditions for mold growth. Homes inundated by floodwaters become vulnerable to production of mold spores, particulate matter, and volatile organic compounds, all of which trigger a variety of poor health outcomes.

Introduction: Facemasks were widely mandated during the recent SARS-CoV-2 pandemic. Especially the use by the general population is associated with a higher risk of improper handling of the mask and contamination and potential adverse microbiological consequences.
Methods: We investigated and quantified bacterial accumulation in facemasks used by the general population, using 16S rRNA (Sanger Sequencing), culture and biochemical analysis along with Rose Bengal staining.

Developing and overseeing Respiratory Protection Programs (RPPs) is crucial for ensuring effective respirator use among employees. To date, a gap exists in research that focuses on elastomeric half mask respirators (EHMRs) as the primary respirator in health delivery settings which would necessitate additional considerations in RPPs beyond the more common N95 filtering facepiece respirators. This paper presents lessons learned during a one-year impact evaluation with healthcare and first responder settings that received EHMRs from the Strategic National Stockpile in 2021 and 2022.

Background: Quantitative mask fit testing (QNFT) is the gold standard to confirm the correct fit of a N95/P2 mask to ensure health care workers protection from airborne viruses. Using the Occupational Safety and Health Administration (OSHA) guidance indicates a final fit test result is a cumulative score derived from manoeuvres within the OSHA protocol. The protocol-based manoeuvres mimic aspects of clinical care by health professionals and mask fit testing is conducted to provide protection from airborne viruses and pollutants within a care setting.
