How to get the most out of your lab’s fume hoods https://synergist.aiha.org/202102-your-lab-fume-hoods When finally selecting a product, a safety professional's first consideration should be the type of materials that this laboratory will use in its hoods. The two main types of laboratory fume hood are constant air volume (CAV) hoods and variable air volume (VAV) hoods. CAV hoods exhaust a continuous volume of air. Face velocitythe speed at which air enters the hood's f...ront openingvaries as sash position changes. VAV hoods, or demand-based systems, adjust the volume of air exhausted while maintaining face velocity at a predetermined level, regardless of sash position. Another critical factor is the fume hood locations relative to supply air vents, doorways, and high-traffic areas. Without acknowledging room mixing efficiency or supply air distribution, a high air exchange rate alone is not enough to promote a healthy indoor air environment and control fugitive emissions within a space. Selecting low-velocity diffusers and paying careful attention to the locations and distributions of supply and exhaust air diffusers (to avoid potential short-circuiting) are the basic design criteria for a room with high mixing efficiency. Airflow monitors are vital to notify laboratory workers when hood flow or velocity falls below predefined unsafe levels. Fume hoods should undergo annual testingat a minimumas decided by the lab's facility or institution.

Great article about 5G https://synergist.aiha.org/202102-generation-gap Some key points: As with older generations of cellular systems, one’s personal exposure is dominated by one’s own use of personal devices.... Closer and more densely placed base stations have the opposite effect: less power is needed to communicate, thus lowering exposure (both ambient and personal). In the U.S., the FCC regulation 47 CFR 1.1310 is mandatory for all license holders, including wireless companies. Canada uses similar limits from Safety Code 6, published in 2015. These standards and the FCC regulation are two-tiered and limit exposures of untrained persons to about one-fifth of those for trained persons. Research conducted over past decades at many different frequencies has shown no reproducible health effects without a measurable increase in tissue temperature. Nonetheless, occupational limits are based on a factor of 10 below levels where health effects have been demonstrated, and limits for untrained workers and the general public are even lower (by a factor of 50).
