2 Basic safety instructions
2.1 Requirements for personnel
The personnel for installation, commissioning, diagnostics and maintenance must fulfill
the following requirements:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task.
‣Personnel must be authorized by the plant owner/operator.
‣Be familiar with federal/national regulations.
‣Before starting work: personnel must read and understand the instructions in the
manual and supplementary documentation as well as the certificates (depending on
the application).
‣Personnel must follow instructions and comply with general policies.
The operating personnel must fulfill the following requirements:
‣Personnel are instructed and authorized according to the requirements of the task by
the facility's owner-operator.
‣Personnel follow the instructions in this manual.
2.2 Designated use
The source containers described in this document contain the radioactive source, which is
used for radiometric point level measurement, level measurement and density
measurement. They screen the radiation from the surrounding environment and allow it
to be emitted almost unattenuated in the direction of measurement only. In order to
guarantee the screening effect and rule out damage to the radiation source, it is essential
to comply strictly with all the instructions provided in these operating instructions for
mounting and operating the unit, as well as all legal regulations surrounding radiation
protection. Endress+Hauser does not accept any responsibility for damage caused by
incorrect use.
When moving or changing the location of the source container, it is absolutely essential to
switch the container to the "AUS/OFF" position (radiation source is switched off).
2.3 Workplace safety
For work on and with the device:
‣Wear the required personal protective equipment according to federal/national
regulations.
2.4 Operational safety
Risk of injury!
‣Operate the device only if it is in proper technical condition, free from errors and faults.
‣The operator is responsible for interference-free operation of the device.
Modifications to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers and render the product approval null and void:
‣If modifications are nevertheless required, consult with Endress+Hauser.
Repair
To ensure continued operational safety and reliability:
‣Carry out repairs on the device only if they are expressly permitted.
‣Observe federal/national regulations pertaining to repair of a device.

Source container FQG66 Basic safety instructions

‣Use original spare parts and accessories from Endress+Hauser only.
2.5 Product safety
This measuring device is designed in accordance with good engineering practice to meet
state-of-the-art safety requirements, has been tested, and left the factory in a condition in
which it is safe to operate.
2.6 Basic instructions for use and storage
• Observe applicable regulations and national/international standards.
• Comply with radiation protection regulations when using, storing and working with the
radiometric measuring system.
• When storing and transporting the source container, pay attention to the center of
gravity and weight indicated on the packaging.
• Heed warning signs and observe safety zones.
• Install and operate the device according to the instructions in this document and as
specified by the regulatory authority.
• Never operate or store the device outside the specified parameters.
• When operating and storing the device, protect it against extreme influences (i.e.
chemical products, weather, mechanical impacts, vibrations etc.).
• Always secure the "AUS/OFF" switch position by using the lock pin and padlock.
• Before switching on the radiation, make sure that no-one is in the radiation zone (or
inside the product vessel). The radiation may only be switched ON by properly instructed
staff.
• Do not operate damaged or corroded devices. Seek the advice of the competent radiation
safety officer immediately if damage or corrosion occurs. Follow instructions.
• Conduct the required leak test according to the applicable regulations and instructions.
LWARNING
The device is exposed to strong vibrations or impact.
‣At regular intervals, please check that the fastening unit is securely seated and stable
and check the condition of the padlock or the retaining element.
LCAUTION
The plant is not in proper operating condition.
Radiation can escape.
‣Check the area around the device for signs of radiation.
‣Notify the radiation safety officer.
2.7 Hazardous area
NOTICE
The suitability of the radiometric measurement method and of the device for
applications in hazardous areas must be checked by the plant operator according to
the national rules and regulations that apply.
‣Compliance with national rules and regulations is mandatory.
The following must be observed:
• Avoid electrostatic charge at the device. Do not rub synthetic surfaces dry.
• Avoid friction sparks and impact sparks.
• The device must be integrated in the plant potential equalization system.

LCAUTION
Source containers with a proximity switch or pneumatic drive are not suitable for
hazardous areas.
‣Do not use source containers with a proximity switch or pneumatic drive in hazardous
areas.
2.8 General instructions on radiation protection
When working with radioactive sources, avoid any unnecessary exposure to radiation. All
unavoidable radiation exposure must be kept to a minimum. Three basic concepts apply to
achieve this:
ABC
A0016373
A Shield
B Time
C Distance
2.8.1 Shield
Ensure the best possible screening between the radiation source and yourself and all other
persons. Source containers (e.g. FQG60, FQG61, FQG62, FQG63, FQG66) and all high-
density materials (lead, iron, concrete) can be used for effective screening purposes.
2.8.2 Time
The time spent in the exposed area should be kept to a minimum.
2.8.3 Distance
Keep as far away from the radiation source as possible. The local radiation dose rate
decreases in proportion to the square of the distance from the radiation source.
2.9 Legal regulations for radiation protection
The handling of radioactive emitters is legally controlled. The radiation protection
regulations of the country in which the plant is operated are of overriding importance and
must be strictly observed. In the Federal Republic of Germany, the current versions of the
Radiation Protection Act and the Radiation Protection Directive apply. The following points
derived from this Ordinance are particularly important for radiometric measurement:
2.9.1 Handling permit
A handling permit is required by the operator of a plant that uses gamma radiation. Permit
applications are made to the local state government or the authority responsible (State
Offices for Environmental Protection, Trade Inspection Offices, etc.). The Endress+Hauser
sales organization will be happy to help you obtain the handling permit.

Source container FQG66 Basic safety instructions
Endress+Hauser 9
2.9.2 Radiation safety officer
The plant operator must appoint a radiation safety officer (RSO) who has the necessary
specialist knowledge and who is responsible for observing the Radiation Protection
Directive and all radiation protection procedures. Endress+Hauser offers training courses
in which individuals can acquire the necessary specialist knowledge.
2.9.3 Control zone
Only persons who are exposed to radiation during the course of their job and are subject to
official personal dose monitoring procedures may work in control zones (i.e. areas where
the local dose rate exceeds a specific value). The limit values for the control zone are
specified in the current Radiation Protection Ordinance applicable for your area.
The Endress+Hauser sales organization will be pleased to provide further information on
radiation protection and regulations in other countries.
2.10 Supplementary safety instructions
Please observe the safety instructions in documents SD00292F/00 (for Canada) and
SD01561F/00 (for the United States).
