elsewhere in the document.

These symbols and signal words are used for specific hazards:

WARNING

r Indicates a hazardous situation which, if not avoided, could result in death or serious

injury.

CAUTION

r Indicates a hazardous situation which, if not avoided, could result in minor or moderate

injury.

NOTICE

r Indicates a hazardous situation which, if not avoided, could result in damage to

equipment.

U For more information about product safety labels, see Safety labels on the system (p. 25)

Important information which is not safety relevant is indicated by the following

symbol:

Q

Tip

Indicates additional information on correct use of the system or useful tips.

Safety precautions System Manual

Safety precautions

Safety information

r Particular attention must be paid to the following safety precautions. If these safety

precautions are ignored, the operator may suffer serious or fatal injury. Each

precaution is important.

Operator qualification

Operators are required to have a sound knowledge of relevant guidelines and

standards as well as the information and procedures contained in all relevant

manuals.

o Do not carry out operation and maintenance unless you have been trained by

Roche Diagnostics.

o Carefully follow the procedures specified in all relevant manuals for operation

and maintenance.

o Leave maintenance, installation, or service that is not described in the manuals to

trained Roche Service personnel.

o Follow standard laboratory practices, especially when working with biohazardous

material.

Safe and proper use of the system

Personal protective equipment o Be sure to wear appropriate protective equipment, including, but not limited to,

safety glasses with side shields, fluid resistant lab coat, and approved disposable

gloves.

o Wear a face shield if there is a chance of splash or splatter.

Accuracy/precision of measured

results

o Do not use reagents that have exceeded their expiry date, otherwise inaccurate

data may be obtained.

o For diagnostic purposes always assess the results in conjunction with the patient’s

medical history, clinical examination, and other findings.

o Each laboratory must verify that reagent performance meets the published

specifications.

Installation o Unpacking and installation must be performed by trained Roche Service

personnel only.

o Leave installation that is not described in this manual or the test-specific

Operator’s Manuals to trained Roche Service personnel.

Correct use o Use the instrument only for preparing liquid samples with the provided reagents.

Operating conditions o Operation outside of the specified ranges, e.g. with excessive environmental

temperature and/or humidity, may lead to incorrect results or malfunction of the

instrument or analyzer.

o Use the instrument and analyzer as indicated in the technical specifications.

o Make sure that the instrument’s and analyzer’s ventilation openings remain

unobstructed at all times.

Roche Diagnostics

System Manual · Version 1.0 17

cobas® 4800 System 1 General safety information

System Manual Safety precautions

o Perform maintenance according to the specified intervals to maintain the

operating conditions of the instrument and analyzer.

o Keep all manuals in a safe place to ensure that it is not damaged and remains

available for use. All manuals must be easily accessible at all times.

Approved parts Use of non-approved parts or devices may result in malfunction of the instrument or

analyzer and may render the warranty null and void. Only use parts and devices

approved by Roche Diagnostics.

Third-party software Installation of any third-party software that is not approved by Roche Diagnostics

may result in incorrect behavior of the system or the software. Do not install any

non-approved software.

Miscellaneous safety precautions

Power interruption A power failure or momentary drop in voltage may lead to data loss. Operation with

an uninterruptible power supply (UPS) is strongly recommended. Check the UPS

regularly to make sure it functions properly.

If there is a power failure, the analyzer is disconnected from the control unit. The

displayed maintenance status of the analyzer may not be correct. To get the correct

maintenance status, refresh the analyzer under Overview > System > cobas z480 tab.

Electromagnetic fields Devices that emit electromagnetic waves may cause the instrument or analyzer to

malfunction. Do not operate the following devices in the same room where the

instrument or analyzer are installed:

o Mobile phone

o Transceiver

o Cordless phone

o Other electrical devices that generate electromagnetic fields

Data backup There is an automatic backup process that stores the data on the D drive. It is the

customers responsibility to perform regular backups of all measurement results.

Relocation and transportation Do not attempt to relocate or transport the instrument or analyzer. Leave relocation

and transportation to personnel trained or authorized by Roche.

System Manual Safety summary

Biohazardous materials

WARNING

Infection by samples and associated materials

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

materials and mechanical components associated with samples of human origin are

potentially biohazardous. Therefore, universal precautions should be taken when handling

and processing samples.

r Follow standard laboratory practices, especially when working with biohazardous

material.

r Keep the main cover closed and in place while the instrument is operating.

r Do not open the thermal block cycler door during operation.

r When working with the main cover open while the instrument is powered on (e.g., for

cleaning or maintenance), always put the instrument in Maintenance mode or in

Shutdown status first.

r Be sure to wear appropriate protective equipment, including, but not limited to, safety

glasses with side shields, fluid resistant lab coat, and approved disposable gloves.

r Wear a face shield if there is a chance of splash or splatter.

r If any biohazardous material is spilled, wipe it up immediately and apply disinfectant.

r If sample or liquid waste comes into contact with your skin, wash it off immediately

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

WARNING

Infection and injury due to sharp objects

When wiping sharp objects, use several layers of gauze.

r Be careful to not puncture yourself.

r Be sure to wear appropriate protective equipment, for example gloves.

Waste

WARNING

Infection by biohazardous waste

Liquid and solid waste originates from samples collected in media that inactivate

potentially biohazardous material. However, as with all human-derived solutions, universal

precautions should be taken when handling waste.

Contact with liquid waste or used pipetting tips may result in infection. All materials and

mechanical components that come into contact with waste are potentially biohazardous.

Therefore, universal precautions should be taken when handling waste.

r Be sure to wear protective equipment. Take extra care when working with protective

gloves; these can easily be pierced or cut which can lead to infection.

r If any biohazardous material is spilled, wipe it up immediately and apply disinfectant.

r If liquid waste comes into contact with your skin, wash it off immediately with soap and

water, and apply a disinfectant. Consult a physician immediately.

r Observe the system safety labels as illustrated in section Safety labels on the system

(p. 25)

WARNING

Contamination of the environment by liquid waste and solid waste

The waste generated during the procedure is potentially biohazardous.

r When disposing of any liquid or solid waste, do so according to the appropriate local

regulations.

U For information about disposal, see Disposal (p. 27)
