Safety Information
CONSUMER PROTECTION
The Consumer Protection Act 1987 Part 1,
refers to Product Liability. This legislation was
issued as a direct result of an EC Directive to
all member states and has been in force with
effect from 01 March 1988.
Bright Instrument Company Limited, ever
mindful of the need to ensure that their
products are not subject to misuse and/or
incorrect handling, have made it their aim to
communicate any possible dangers to their
customers.
Whilst Bright Instrument Company Limited
markets products manufactured to the highest
safety standards, it is in the interest of the
purchaser that he is aware of the resultant
dangers of misuse and/or incorrect handling
of these products.
Your attention is therefore drawn to the
following precautions:
Electrical Microtome Knives
& Blades
a. Warnings - A warning notice is fixed to
the instrument stating that it should be
disconnected from the power supply before
removing the panels. This warning should
be strictly observed. This cryostat is fitted
with an in line mains filter which may affect
portable appliance test results.
b. Fuses - Fuse ratings are clearly indicated
on all fuse panels adjacent to the fuse holder.
If and when replacement is necessary, the
correct fuse rating must be adhered to.
c. Earthing (Grounding) - A protective earth
terminal is fitted, and must be used in all two
wire installations.
NB. It is recommended the OTF6000
is plugged in via an electrical surge
protection unit.
Microtome knives can be hazardous in the
laboratory. Personnel should be made aware
of the dangers and observe the following
warnings:
a. Do not leave the microtome unattended
with an exposed knife in position. Remove the
knife, or cover it with the guards provided.
b. Do not leave knives lying around. Place
knives that are not in use in their boxes.
c. Do not carry knives unless secure in the
box provided.
d. Do not clean the knife along its length.
Wipe from the back edge of the cutting edge.
e. Remember that even used knives are
dangerous – they are still sharp and may
have been used to cut potentially infectious
specimens.
f. Dispose of used knives with the same care
as other sharp objects. On no account should
used knives be placed in waste bins.

Suggestions
Fluids supplied as accessories with Bright
instruments, such as Cryospray 134,
Cryo-M-Bed and microtome oil, are strictly for
laboratory use only. They should not be taken
by mouth and precautions afforded to other
laboratory chemicals should be adhered to.
Parts of this instrument may attain
temperatures as low as -50ºC. It is important
to avoid bare skin touching things such as
cold surfaces. When in doubt, wear gloves.
Avoid touching the knife, it is cold as well as
sharp! Always use knife guards.
When placing object holders in the microtome,
when orientating, manipulating or in any way
placing fingers in a position above the knife
edge - ensure that the handwheel is locked
and knife guards are in position.
