The installation of a berm must not impede the flow of water from the emergency shower into the floor drain. For Biosafety Level 2 applications, fume hoods are not appropriate; a fume hood is not designed for the usage of biological materials. 1. Receptacles that are not readily accessible or receptacles for appliances occupying dedicated space, which are cord-and-plug connected in accordance with NEC Section 400-7A(6-8), are exempted. Many supply diffusers and room exhaust room outlets are located along laboratory walls. 13. Note that there are numerous regulations governing the proper use of compressed gas cylinders; use is not addressed by the Guide, as it is a work practices issue, rather than design feature. Class 3 and 4 unstable (reactive) materials. Air exhausted from laboratory work areas shall not pass unducted through other areas. Construction of the venting duct should be equal to the rating of the cabinet. 5. 24 CCR, Part 2 (California Building Code). A fume hood exhausts a substantial amount of air. 3. separate ventilated gas storage rooms without other occupancy or use, which have explosion control. EH&S considers the following to be substances which can cause corrosion, severe irritation, or permanent tissue damage, or which are toxic by absorption: EH&S considers the following to be substances which are corrosive or severely irritating to the skin or which are toxic by skin absorption: The user of the Guide is required to include the design feature.
