Safety precautions

CAUTION

To avoid serious or fatal injury, read and comply with the following safety

precautions.

Operator qualification

Insufficient knowledge and skills As an operator, ensure that you know the relevant safety precaution guidelines and

standards and the information and procedures contained in these instructions.

o Do not carry out operation and maintenance unless a Roche representative has

trained you or your trainer to do so.

o Leave maintenance, installation, or service that is not described to trained Roche

Service representatives.

o Carefully follow the procedures specified in the instructions for operation and

maintenance.

o Follow standard laboratory practices, especially when you work with

biohazardous material.

Safe and proper use of the system

WARNING

Personal injury and infection due to sharps, rough edges, and/or moving parts

r Good Laboratory Practice can reduce the risk of injury. Be aware of your laboratory

environment, well-prepared, and follow the instructions for use. Some areas of the

instrument may have sharps, rough edges, and/or moving parts. Wear personal

protective equipment to minimize the risk of injury from bodily contact with such parts,

especially in less accessible areas, or while cleaning the instrument. Your personal

protective equipment should be appropriate to the degree and type of potential hazard,

e.g. suitable lab gloves, eye protection, lab coat, and footwear.

WARNING

Missing personal protective equipment

Working without personal protective equipment means danger to life or health. Using the

instrument in a way that is not described by the manufacturer can impair the protection

provided.

r Wear appropriate personal protective equipment, such as:

o Lab gloves

o Lab coat

o Eye protection

o Face shield if there is a chance of splashing or splattering

System not used for an extended

period

o If the system will not be used for more than 24 hours, put the system out of

operation.

o Remove and refrigerate any remaining reagents.

o For further information, call your Roche Service representative.

Non-approved parts Use of non-approved parts or devices may result in malfunction of the system and

may render the warranty null and void.

o Use only parts and devices approved by Roche Diagnostics.

Safety precautions

Installation and deinstallation

Transport Risk of personal injury when lifting. The cobas b 123 POC system, without

consumables in the bottle compartment and AutoQC materials in the AutoQC

module, weighs approximately 20 kg.

o Perform the put out of operation procedure before moving the system.

u Put out of operation (p. 134)

o Do not attempt to relocate or transport the system without the assistance of

another individual.

o Do not attempt to lift the system with a Fluid Pack and AutoQC Pack in the

system. In addition, make sure that before lifting, there are no other objects

attached to the system.

o Lift the system only from its designated holding points.

u Holding points (p. 87)

Errors in installation Only trained Roche Service representatives may install the system.

o Leave installation that is not described to trained Roche Service representatives.

Disposal A biohazardous system may lead to infection.

o Treat the system as biohazardous waste. Decontamination (the combination of

processes including cleaning, disinfection, and/or sterilization) is required before

reuse, recycling, or disposal of the system.

o Dispose of the system according to the local regulations. For more information,

contact your Roche service representative.

Operating conditions

NOTICE

Unsuitable operating conditions

Operation outside of the specified ranges may lead to incorrect results or malfunction of

the system.

r Use the system indoors only, and avoid heat and humidity outside of the specified

range.

r Make sure that the system’s ventilation openings always remain unobstructed.

r Keep the analyzer away from all sources of liquids, such as sinks and wash basins.

r Keep the operating instructions undamaged and available for use. Operating

instructions have to be easily accessible for all users.

Electromagnetic interference Strong electromagnetic fields (originating from unshielded radio-frequency sources)

can interfere with proper operation and may lead to malfunction of the system and

incorrect results.

o Do not use this system near sources of strong electromagnetic fields because these

fields can interfere with its proper operation.

o Evaluate the electromagnetic environment before you operate the system.

o Take measures to mitigate the interference.

Safety precautions

Electrical safety

CAUTION

Electrical shock

Removing the covers of electronic equipment can cause electric shock because there are

high-voltage parts inside.

r Do not attempt to work in any electronic equipment.

r Do not remove any cover of the system except those covers specified in the

instructions.

r Only Roche Service representatives may install, service, and repair the system

Electrical specifications Comply with the following electrical specifications when operating the

cobas b 123 POC system:

o The power cable has to be connected into a grounded power socket. If you

connect the instrument to an extension cable, the extension cable has to be

connected into a grounded power socket.

o The power cable has to conform to country-specific requirements. Contact your

Roche Service representative for more information.

o Only use electrical accessories, such as power cables, provided by Roche. Do not

alter any electrical equipment on the instrument, or any electrical accessories that

accompany the system.

Biohazardous materials

Infectious samples Contact with samples containing material of human origin may result in infection.

All materials and mechanical components associated with samples containing

material of human origin are potentially biohazardous.

o Follow standard laboratory practices, especially when working with biohazardous

material.

o Keep all covers closed while the system is operating.

o Follow the instructions in this manual when performing procedures with the top

cover of the system removed.

o Wear appropriate personal protective equipment.

o If any biohazardous material is spilled, wipe it up immediately and apply a

disinfectant.

o If sample or waste comes into contact with your skin, wash the affected area

immediately with soap and water and apply a disinfectant. Consult a physician.

Sharp objects Contact with probes or needles may result in infection.

o When you wipe probes or needles, use several layers of gauze and wipe from the

top down.

o Take care not to puncture yourself.

o Wear appropriate personal protective equipment. Take extra care when working

with lab gloves, which can easily be pierced or cut, leading to infection.
