Nice to see.  Those rules are also in the current OSHA electrical code and the NEC code.  The violation I continually see is a power cord plugged into a power bar or vice versa.  There is a common misconception that a power bar is not an extensions cord.

Based on Underwriter Laboratories (UL) recommendations:
=B7         Power (PTap)s  are not intended to be permanently secured to building structures tables, work benches and any other structure.
=B7         PTs should not be used as a substitute for fixed wiring.
=B7         Power taps or extension cords should not be connected to each other. Doing this can overload the circuit creating a potential fire hazard.
=B7         Power taps are not designed for high power loads such as space heaters, refrigerators and microwave ovens, which can easily exceed the recommended ampere ratings on many power strips.
However they are always present inside the chemical fume hood to supply the power to various instruments.
Good luck.

DCHAS group members,

Does anyone know of any power strips that are rated for use within chemical fume hoods? Typically the "standard" power strips are not recommended for such use.

Thank you in advance for any feedback you can provide.
