7.5 Each hood shall be posted with a notice giving the date of the last periodic field
test. If the hood failed the performance test, it shall be taken out of service until
repaired, or posted with a use restriction. The notice shall state the partially closed
sash position necessary for safe/normal operation and any other precaution
concerning the type of work and materials permitted or prohibited.
4.2 Ductless fume hoods shall have signage prominently posted on the ductless
hood to inform operators and maintenance personnel on the allowable chemical
used in the hood, type and limitation of filters in place, filter changeout schedule and
that the hood recirculates air to the room.
4.2 Records shall be maintained for all inspections and maintenance. If testing
involves Quantitative values (such as throat suction) the observed values shall be
recorded. Inspection forms designed for several categories of testing shall be
provided and shall include the normal values for the parameter tested.
Each hood shall be posted with a notice giving the date of the routine performance
test, and the measured average face velocity. If it is taken out of service it shall be
posted with a restricted use or out of service notice. The restricted use notice shall
state the requisite precautions concerning the type of materials permitted or
prohibited for use in the hood.
