not be exposed to conditions whereby dangerous gas concentrations can occur.

HAZARD OF RADIOACTIVE RADIATION

When working with radioactive specimens observe all applicable radiation safety procedures. When working

with radioactive contaminated material, appropriate safety and disinfection measures must be carried out.

According to the rules and regulations concerning the handling of radioactive contaminated material of the

respective laboratory, safety clothing (e.g. particle mask, gloves, protective shoe covers) must be worn.

Radioactive contaminated waste must be disposed of according to the respective regulations.

HAZARD OF INFECTION

Specimens used during the intended operation of the instrument might potentially be infectious. For this

reason, it is recommended to observe the general laboratory regulations concerning protection against

danger of infection.

Information on decontamination media, their use, dilution and effective range of application can be read in

the Laboratory Biosafety Manual : 1984 of the World Health Organization.

When working with infectious specimens observe all applicable safety procedures. When working with

infectious material, appropriate safety and disinfection measures must be carried out. According to the rules

and regulations concerning the handling of infectious material of the respective laboratory, safety clothing

(e.g. particle mask, gloves, protective shoe covers) must be worn. Infectious waste must be disposed of

according to the respective regulations.

CARE IN USING MICROTOME KNIFE

To diminish the danger of being injured by the knife or blade, use the knife guard when adjusting specimen

and knife. If possible, the specimen should be clamped in before the knife is inserted into the knife holder.

Before changing the knife holder, always remove blade or knife! Unused knives should always be kept in a

knife case. Never place the knife with the cutting edge upwards. Never try to catch a dropping knife!! Never

check the sharpness of the cutting edge with your fingers. The cutting edge is extremely sharp!

HAZARD OF MALFUNCTION

To avoid the hazard of malfunction of an instrument, it must only be operated in a controlled electromagnetic

environment. This means that transmitters such as mobile phones must not be operated in their close

vicinity.

In case of malfunctions and/or service work, please turn off the instrument and contact your local dealer.
