•
Structural changes to the chamber without a subsequent risk assessment by the operator
•
Failure to observe the inspection and maintenance regulations (inspection before initial commissioning,
recurring tests, inspection after maintenance or repairs, qualification of the tester)
• Replacement of the CO
2
compressed gas cylinder by untrained personnel
•
Commissioning after maintenance or repairs without passing the electrical and safety tests
•
Installation, commissioning, operation, maintenance or repair of the chamber without the existence of a
risk assessment and operating instructions of the operator
• Door opening when the main switch of the gas detection system is switched on
•
Operation with the main switch of the gas detection system switched off
•
Non-observance of the relevant regulations for handling lithium-ion accumulators
• Failure to observe the relevant regulations for handling CO

and inert gases. DGUV Information 205-
026 must currently be taken into account for the operator in Germany.
To prevent these and other risks from incorrect operation, the operator shall issue operating instructions.
(chap. 5.3). The operator is also recommended to create Standard Operating Procedures (SOPs) (chap.
5.5).
4. Residual Risks
The unavoidable design features of a chamber, as well as its proper field of application, can also pose risks,
even during correct operation. These residual risks include hazards which, despite the inherently safe de-
sign, existing technical protective equipment, safety precautions and supplementary protective measures,
cannot be ruled out.
Messages on the chamber and in the Operating Manual warn of residual risks. The consequences of these
residual risks and the measures required to prevent them are listed in the Operating Manual. Moreover, the
operator must take measures to minimize hazards from unavoidable residual risks. This includes, in partic-
ular the Operator measures described in chap. 2.4.3. Residual hazards are to be taken into account by the
operator in their risk assessment. Based on a risk assessment, the operator must create appropriate oper-
ating instructions.
The following list summarizes the hazards against which this Operating Manual and the Service Manual
warn, and specifies protective measures at the appropriate spots (list is not exhaustive):
Unpacking, Transport, Installation
• Sliding or tilting the chamber
•
Setup of the chamber in unauthorized areas
•
Installation of a damaged chamber
• Installation of a chamber with damaged power cord
• Inappropriate site of installation
•
Missing protective conductor connection
•
Improper connection of customer inerting unit
• Improper connection of CO
2
compressed gas cylinder, empty CO
2
compressed gas cylinder
• Lack of extraction connection (technical ventilation in accordance with the country-specific regulations)
to the extraction nozzle of the chamber
•
Inaccessibility of the emergency shutdown of the chamber
