The correct answers to which regulations may help you decide when a ducted fume is needed -

1. Whenever your Chemical Hygiene Plan says so.

2. The OSHA Laboratory Standard clearly implies that a vented hood should be used when volatile or toxic substances are present which may result in an exposure above PELs or a chemical health or physical hazard that may be eliminated by engineering controls.

3. The OSHA General Duty Clause indicates it is the employer's obligation to safe workplace for all employees. That would logically include providing appropriate controls, including proper ventilation.

Does anyone know of any regs that specifically state WHEN fume hoods are required, specifically ducted hoods?

Thank you,
