2.5.1 General dangers associated with fire extinguishing systems

Inst. and Maint. Manual | Oxeo PR LCP | F_101921 Rev 02 | 10-2022 | en
10
Electrical current
Oxygen deficiency
DANGER Risk of death due to electric shock
An imminent, risk of death due to electric shock exists if live components are touched.
Damage to the cable insulation of individual components involves the risk of fatal
injury. Moreover, incorrect connection can cause system malfunctions.
• Allow only qualified electricians to work on electrical components and the electrical connec-
tion.
• If there is damage to the cable insulation, shut off the power supply immediately and replace
defective cables with new cables.
• Prior to starting tasks on live components of electrical equipment and supplies, establish the
de-energized state and ensure this state for the duration of the tasks. In this process comply
with the 5 safety rules:
1. Power down.
2. Safeguard against restart.
3. Ensure de-energized state.
4. Ground and short circuit.
5. Cover or shield any adjacent live components.
• Never remove safety devices, change them, or render them inoperable. Only replace defec-
tive fuses with fuses of the same amperage.
• Keep moisture away from live components. This may lead to short circuits.
WARNING Risk of death due to oxygen deficiency
If the extinguishing agent concentration exceeds 52% by vol. (LOAEL), the extinguish-
ing agent can have a toxic effect due to the reduced oxygen concentration. A danger
of asphyxiation exists with extinguishing agent concentrations above 62% by vol.
• Ensure that the locally applicable directives for rooms used for the storage of extinguishing
agent containers are complied with.
• Comply with NOAEL (No Observed Adverse Effect Level) and LOAEL (Lowest Observed
Adverse Effect Level) and ensure that the limit values are not exceeded.
• Avoid inhaling vapors, aerosols, and atomized spray.
• Comply with the safety data sheet for the extinguishing agent.

Extinguishing agent cylinders under high pressure
2.5.2 Dangers when the system is activated
Cold extinguishing agent
Shock
WARNING Risk of death due to pressure in extinguishing agent cylinders.
If pressurized extinguishing agent cylinders are damaged and extinguishing agent
escapes uncontrollably, there is a risk of severe injuries.
• Do not transport or store extinguishing agent cylinders unless they are sealed with a protec-
tive valve cap and a lock nut.
• Ensure that the extinguishing agent cylinders are attached correctly.
• Replace damaged extinguishing agent cylinders immediately.
WARNING Risk of injury from cold extinguishing agent.
The extinguishing agent exiting at the discharge nozzles is very cold. Direct contact
may result in injury.
• Leave the extinguishing zone without delay and within the pre-discharge timer when an
alarm is given.
• Stay out of the direct flow area of a discharge nozzle.
WARNING Risk of injury from shock.
The activation of the system involves noises from the discharged agent which may
surprise persons to an extent that they suffer shock.
• Inform all persons staying inside or close to the protected enclosure about the existence of
an automatic fire suppression system and the possibility of the system's activation.
• Make persons familiar with the procedures required in the event of an alarm, a fire, or the
activation of the fire suppression system.
• If in doubt, deny persons direct access to the protected enclosure.

Inst. and Maint. Manual | Oxeo PR LCP | F_101921 Rev 02 | 10-2022 | en

Faulty activation
WARNING Risk of injury from faulty activation.
A faulty activation of the system may cause severe injuries and property damage.
• Activate the system only in the event of a fire.
• Protect the manual release devices in the protected enclosure from inadvertent activation.
• Refrain from smoking inside the protected enclosure.
• Before performing any work generating heat and smoke, observe the following:
1. Isolate the system.
2. Switch off the fire alarm system.

Inst. and Maint. Manual | Oxeo PR LCP | F_101921 Rev 02 | 10-2022 | en 13
Falling and flying objects
Noise
Effects of cold
WARNING Risk of injury from falling and flying objects.
The discharge velocity of the extinguishing agent may cause objects to tip over or
become airborne or to be damaged. This can cause severe injuries and significant
material damage.
• Do not place any loose objects into the discharge zone of the discharge nozzles.
• Exit the extinguishing zone without delay and within the pre-discharge timer when an alarm
is given.
• Do not place any sensitive objects (e.g. hard drives) directly into the discharge zone of the
discharge nozzles.
WARNING Risk of injury from noise.
High sound pressure levels caused by discharged gas and acoustic alarm equipment
(e. g. signal horns) may cause hearing damage.
• Leave the extinguishing zone without delay and within the pre-discharge timer when an
alarm is given.
• Stay out from the immediate vicinity of acoustic alarm equipment and discharge nozzles.
NOTICE Property damage from cooling ambient air.
The discharged extinguishing agent extracts heat from the ambient air contained in the
extinguishing zone. This causes the air in the immediate discharge zone of the extinguish-
ing nozzles to cool to below -58 °F (-50 °C).
• Do not attach/store components that are sensitive to cold in the immediate vicinity of the dis-
charge nozzles.
