5 Assembly instructions
The LOX system uses a nitrogen generator. The nitrogen generator uses the air from the environment and separates the
oxygen and nitrogen, leaving a high concentration of nitrogen. The nitrogen is used to condition the area to be secured. The
oxygen is released into the immediate surroundings and then ventilated to the outside. Active fans must be used if the
natural air circulation is not sufficient.
Het LOX systeem is een samenstel van meerdere machines. Het gezamenlijke doel van de samengestelde machines is het
conditioneren van de te beveiligen ruimte doormiddel van suppletie van stikstof. Om het doel van zuurstofreductie te
bereiken is het noodzakelijk om het systeem op de juiste manier te monteren. Hiervoor zijn er een paar voorschriften van
toepassing:
The LOX system is a combination of several machines. The joint purpose of the combination of machines is to condition the
room that needs to be secured by means of nitrogen supplementation. To achieve the goal of oxygen reduction, it is
necessary to assemble the system in the right way. For this purpose, a few regulations apply:
- The ventilation capacity of the technical room in which the LOX system is installed must be considered. Sufficient
ventilation of oxygen-enriched air is necessary to avoid a fire hazardous atmosphere.
- The assembly and positioning of the components of the LOX system must be in accordance with the pre-fabricated
installation drawing. The installation drawing is worked out specifically for each system and is available in the
technical file of the system.
- Part of the connections between the components can be fixed pipe connections. Fixed pipe connections must
always be manufactured in accordance with the manufacturer's specifications.
6 Measures during decommissioning
The moment that the LOX Low Oxygen system is decommissioned, the oxygen content in the protected area will gradually
increase to the regular atmospheric value. This means that the fire protection by oxygen reduction is no longer functional.
It is advisable for the user to take appropriate (organisational) measures for such situations in order to ensure fire safety in an
alternative way. These precautions could be included in the emergency response plan.
In addition to restoring the LOX system, one or more of the following measures can be taken:
- Lock the secured section to make sure that the oxygen reduced atmosphere is maintained as long as possible;
- Maintain the reduced oxygen atmosphere by connecting an external nitrogen provision ( by example a tank truck);
- Extra checking rounds by fire guards;
- Prohibiting work that could result in an increased fire risk;
- Keeping the emergency response organization and / or the fire brigade continually on standby.
