• Fume Cupboards:.
• In the chemical laboratory, adequate control of inhalable chemical substances hazardous to health is generally achieved by placing the work inside a fume cupboard, which effectively reduces exposure levels. There are many factors which affect the capability of a laboratory fume cupboard to provide efficient containment for the hazardous chemicals used in any particular experiment; amongst these are: .
• the rate of release within the fume cupboard of any toxic substance(s); .
• the amount of heat generated within the fume cupboard; .
• bulky apparatus within the fume cupboard which may distort the air flow; .
• It is readily apparent from the above list that the only person who can be expected to be able to make a realistic assessment of any particular fume cupboard’s performance under experimental conditions is the person using the fume cupboard, for it can only be he or she who can estimate most of the above parameters and their interaction. ...
• Within all University laboratories, when the fume cupboard sash opening is set by aligning the arrow on the sash itself with the arrow on the carcass of the fume cupboard, a minimum face velocity will be achieved for the cupboard to pass a standard smoke containment test. ... Opening a fume cupboard sash past the marked aperture can often lead to a dramatic decrease in front face velocity. ...
• The following basic rules for using a fume cupboard should always be observed: .
• The extract fan must be on when the fume cupboard is in use for experiments and when it contains volatile compounds. ...
• Fume cupboards used for experimental purposes must not contain any stored chemicals. ...
• For experimental purposes, each fume cupboard must be totally allocated to the control of one person. ...
• It must be possible to close the sash quickly without any risk of disturbing apparatus in the fume cupboard. ...
• All laboratory fume cupboards are inspected and tested by Works Division on an annual basis. ...

• Laboratory Fume Hood Program.
• To ensure the laboratory fume hoods are operating in accordance with University requirements. ...
• To establish design criteria consistent with professionally recognized consensus standards and practices to provide the best level of protection and performance for new laboratory fume hoods installed at Rutgers University.
• Laboratory fume hoods provide the primary control measure available in the laboratory to minimize exposure to toxic gases, vapors, mists, or fumes generated by the manipulation of chemicals during research activities. REHS measures fume hood face velocity annually to confirm proper operation, and notifies Facilities Maintenance of fume hoods with poor velocity for repair. The laboratory researchers, REHS, and Facilities must work together to ensure fume hoods operate and are used properly to provide adequate protection to the end user. The following summarizes the responsibilities for each in the Rutgers fume hood program.
• Use the fume hood with the sash as low as possible, at or below the indicated operating height. The fume hood is more effectively at the sash operating height and provides a physical barrier between you and the fume hood contents. ...
• Do not store chemicals or equipment that are not in use within the fume hood, and do not place these items at the front edge of the hood or at the rear baffles (openings) of the hood. ...
• Do not use perchloric or hydrofluoric acid inside a fume hood unless the hood was specifically designed for its use. Due to the physical properties of these materials, special fume hoods are required for work with these materials. ...
• Immediately report fume hood malfunctions to Facilities Maintenance for repair. ...
• Review the laboratory fume hood requirements for Special Use Hoods and design specifications whenever new uses of hoods are anticipated or when renovation requires the installation of new fume hoods. ...
• Notify the department administrator and/or lab users when repairs are planned for fume hoods. ...
• Do not remove contents from inside the laboratory fume hood. If repairs are required inside the laboratory fume hood, have user remove its contents to provide access inside the hood. ...

• MANGANESE FUME .
•        OSHA previously had a ceiling limit of 5 mg/m3 for manganese fume, measured as manganese. Because of this substance's potential for damage to the lungs and central nervous system, the ACGIH recommends an 8-hour TWA of 1 mg/m3 and a 3-mg/m3 STEL for manganese fume. ...
• Health surveys of employees exposed to manganese fume have demonstrated a high incidence of pneumonia in these workers (Davies 1946, as cited in ACGIH 1986/Ex. ... 1-388) found seven cases of pneumonia and 15 borderline cases of pneumonia among 144 workers exposed to manganese dust or fume concentrations greater than 5 mg/m3; three of these cases were associated with fume rather than dust exposure. Those workers exposed to fume levels below 5 mg/m3 exhibited no signs of pneumonia. ... 3 mg/m3 manganese fume. ...
•        OSHA received several comments on manganese fume and dust (Exs. ... Some commenters stated that reducing the PEL for manganese fume would have a large impact on their industries but did not provide any details (Exs. ... , a manufacturer of manganese products, supports the reduction in the PEL for manganese fume from a ceiling of 5 mg/m3 to an 8-hour TWA of 1 mg/m3 and a STEL of 3 mg/m3. ...
•        Based on a review of all of the record evidence, the final rule establishes a 1-mg/m3 TWA and a 3-mg/m3 STEL for manganese fume. ...

• Although, under ideal conditions, face velocity and fume hood containment/performance/safety are related, they are not the same.   It is a common mistake to equate an acceptable face velocity with acceptable fume hood performance. ...
• The traditional face velocity method of testing fume hoods has been proven to be inadequate to describe actual containment performance and should be replaced immediately, industry-wide  with a containment-based test such as the ASHRAE 110-1995 or similar method. ...
• The modified ASHRAE 110 fume hood performance testing/commissioning method .
• The test method outlined below is based on the ANSI/ASHRAE 110-1995 Method of Testing Performance of Laboratory Fume Hoods (ASHRAE 110). It reflects some modifications made to the method to correct some shortcomings and reflect the results of field research on laboratory fume hood performance testing completed after the ASHRAE 110 method was published in 1995, most of which will almost certainly be incorporated into the next revision of the standard due to be published in 2000. ...
