GENERAL
Fume hoods are exposed to extremes o temperature, reagent
umes and working sur ace abuse. Regular care will prolong
service li e and insure sa e working conditions.
The exhaust system and blower o a ume hood must unction
properly or sa ety. Maintenance personnel should service the
an and motor assembly regularly, lubricate as required, and
make sure that the exhaust system is ree rom obstructions.
Semiannually, accumulated deposits should be removed rom
the impeller blade and housing.
A simple test with lighted match or smoke will show i the air is
being drawn into the hood. More accurate checks o air velocity
can be made with a thermal anemometer. See Inspection and
Field Evaluation procedure.
Always place equipment and apparatus as ar back into the
ume hood as possible since this provides greater assurance o
proper ume collection and removal.
Large, bulky apparatus or equipment should be placed in the
ume hood to permit air low around it, and never placed so as
to inter ere with the operation o the ba le system. Raise large
items an inch or two above work sur ace. Spilled liquids, acids,
or corrosive materials should be immediately wiped up and the
sur ace neutralized with water or the proper neutralizing agent
so as to prevent damage to the work sur ace and the hood
interior or to apparatus and equipment installed in the hood.
Remember that special ume hoods are required or the
handling o Perchloric Acid. See next page.

PERCHLORIC ACID HOODS
The properties o perchloric acid require that a specially
designed ume hood be set aside or exclusive use with this
material. The hood is equipped with a cold water spray device
or washdown o the interior sur aces. A trough is placed
across the back o the hood or collection and disposal o
washdown waters. Operating personnel should be well trained
in the proper handling techniques and be amiliar with the
characteristics o this material.
Frequency o washdown, both hood interior and exterior
system, is determined by the usage and concentration o
reagents. This can range rom a weekly procedure to one that
occurs a ter every use. Washdown should always be ollowed
by an inspection to veri y that all areas are clean and that the
wash system is unctioning properly.
Some o the hazards o perchloric acid which justi y the use o
a special hood are:
1. Perchloric acid is a very strong acid, capable o producing
severe burns when in contact with skin, eyes or respiratory
tract.
2. As an aqueous solution, it can cause violent explosions i
improperly handled.
3. It reacts with other substances to orm unstable materials
which are susceptible to exploding either by impact, riction,
or spontaneous combustion.
Persons using perchloric acid should be thoroughly amiliar with
its hazards. Many reported laboratory accidents have involved
less than one gram o reactant. Listed below are some common
sa ety practices that should be ollowed:
• Spilled perchloric acid should be thoroughly washed away
with large amounts o water.
• The use o organic chemicals or materials in the hood should
be avoided.
• Goggles or other e ective eye protection should be used
whenever possible, as well as utilization o the ume hood
sash or additional sa ety.
• Gas lames or oil baths should not be used within the hood.
• Organic chemicals should not be kept in storage areas set
aside or perchloric acid storage.
• A schedule should be made or regular washdown and
inspection o hood interior, ductwork and blower to guard
against a build-up o dangerous perchloric materials.
• Only a luorocarbon grease should be used as a blower
lubricant, since any other type is to be considered potentially
hazardous.
• Washdown procedure should be per ormed a ter completion
o usage with all apparatus removed rom hood.

NOTE: I a drain tube is required, it should be installed at
this time. The tube is located at the le t end o the trough
and is ed through the top o the le t hand base cabinet into
a one gallon container.
4. Install poly vent, i required, through pre-drilled holes in the
backs o base cabinets. The tail piece o the vent is supplied
with a double compression assembly to lock it in place.
5. Seal the top edge o the trough assembly with a RTV silicon
or other applicable sealer and then place the ume hood
work sur ace into the Top Filler Frame. I base cabinet poly
vents are used, align them to the pre-cut holes in the work
sur ace.
6. Install cupsinks i required. The ume hood base cabinets are
supplied with pre-punched holes in the back panels above
the stone liner or cupsink drains. Cupsink assemblies are
supplied with the sink, an extension pipe, an elbow, and a
pipe section that protrudes through the hole in the base
cabinet back. The cupsink assembly is designed to it two
conditions.
A. When the ume hood assembly is supplied with the
Optional Height Filler Frame, the cupsink assembly is
ished through the sink cutout hole in the work sur ace
and the drain line hole at the rear o the base cabinet.
B. When the ume hood is supplied with only the Top Filler
Frame, the extension pipe below the cupsink is removed
to maintain alignment with the base cabinet rear drain
hole. The pipe extension should be saved in the event
that the Optional Height Filler Frame be required at a later
date.

FUME HOOD MONITOR
Models 54L0335 and 54L0405
Proper ume hood operation is key to laboratory sa ety, com ort
and energy management. OSHA requires that laboratories take
measures to ensure proper and adequate operation o ume
hoods. Recommendations include the use o a continuous air
monitoring device. The ANSI Z9.5 and NFPA 45 standards
rein orce these requirements.
Fisher Hamilton monitors have the ability to monitor true ume
hood ace velocity using thermal sensors located in the
instrument. The thermal sensors are exposed to clean
laboratory air only. They can be sur ace-mounted in minutes
eliminating the need or expensive panel cutouts.
Each model is equipped with indicator lights that illuminate
based on a pre-determined set-point. An audible 85dB
piezoelectric alarm sounds and a red indicator light illuminates
to warn o potentially dangerous low air low conditions.
•54L0405
– Low low set point
– Audible and visual alarm
– I/O options
•54L0335
– Analog meter
– Audible and visual alarm
– I/O control
