There is also an increase of potential contamination within the cabinet if the autoclave is not functioning properly since the steam may contain spores or aerosols. The exhaust fan motor should not be located within the duct work. Fume hoods should not be located adjacent to a single means of access to an exit. CCR, Title 24, Part 9, Section 8003.3.1.4. 49. Main Domestic Market:All India. Z9.5-2003 allows air velocities up to 50 fpm, but lower room air velocities around hoods cause less interference with the operation of the hood. The path of travel must be free of obstructions. State of California, Department of Health Services, Radiologic Health Branch DOHS 2010 Sewer connections cannot be made until the building permit documentation has been submitted to the Stanford Utilities Department Environmental Quality staff. This will then assist in determining the space and location required for the gas delivery system and cylinder storage area.

Every year RP Gas Piping finds gas piping and gas appliances that have not been properly installed. It covers the following types of equipment: emergency showers, eyewash and eye/facewash equipment, and combination shower and eyewash or eye/face wash. Class II-B cabinets do not allow in-room venting of exhaust air and are thus appropriate for such uses. Depending on the type and quantities of radioactive materials or the location of the facility, fume hoods used with volatile radioactive materials have specific design requirements.

Wooden bench tops are not appropriate because an unfinished wood surface can absorb liquids. Projects within the campus site are covered by the Universitys existing Hazardous Waste Generator permit. Other potential hazards that may be adjacent to the path of travel that might cause further injury should be considered. These doors should be provided with interlocks so that both doors cannot open at the same time. An approved supervised smoke detection system shall be provided in rooms or areas where highly toxic compressed gases are stored indoors. The Hazardous Materials Program Division of the Environmental Health and Safety Department submits these plans in order obtain a permit. Stanford EH&S presumes that laboratory fume hoods contain hazardous substances that require emergency eyewash and shower facilities.

Laboratory areas shall be provided adequate natural or artificial illumination toensure sufficient visibility for operational safety. Though there are many other areas that must be considered, the primary areas of concern are where to locate the gas storage area outside the laboratory, how much gas will be required, and how the gas will be delivered to the end use points. d. Liquid-tight bottom with a door sill of at least 2 inches. Portable hoods often do not meet the regulatory airflow requirements. Laboratory staff are at risk of injury every time they need to move a gas cylinder and this need can arise often, sometimes every week or every few days, depending on a lab's gas usage. j) Each perchloric acid hood must have an individually designated duct and exhaust system. The system should have minimum leak integrity of 1 108 standard cm3/sec of helium, which equals the volume of a cubic centimeter escaping or entering over 3.1 years. 3. PRO. As new instruments are added to meet increasing demands, gas piping systems can grow into a tangle of tubing, line regulators and traps, making it difficult to carry on preventative maintenance. Consult with EH&S for any exceptions or if an evaluation is needed. Fluorescent bulbs radiate less heat than conventional bulbs while maintaining a safe and illuminated work area inside the hood. 6. A greater degree of safety will result when nonlaboratory work and interaction is conducted in a space separated from the laboratory. 17. 2. Floor drains willalso facilitate required monthly testing. Exposure to hazardous materials and/or pathogenic organisms can occur by hand-to-mouth transmission. This French-language brochure contains descriptions, dimensional data and ordering information on Protector XStream, Premier and XL Laboratory Fume Hoods and SpillStopper Work Surfaces.
