3.9.Fire Precautions
Take all the precautions stated in section “1.5” (Fire and Explosion) against any fire and explosion possibility.
There must be an emergency escape route and scenario in case of any fire and explosion possibility.
A fire alarm system and an extinguisher in accordance with the legal regulations and standards about fire and
explosion, must be provided around the generator set.
The room in which the generator set installed, must be free of any flammable material or any accumulated garbage
by considering any fire possibility.
The fuel line must be adequately secured with free fall type shut of valves.
Do not allow smoking in the room that the generator set is installed in. Also keep any arc, spark or flame away
from here.
3.10.Earthing
In many electrical systems, the non-active parts and the parts connected to these non-active ones, must be
attached to the ground with the help of a conductor or an electrode. This principle is called is called earth
grounding.
The parts and the equipment that are directly exposed to electrical voltage, must be well-insulated in order to
ensure the durability and safety of the electrical system and staff around it. However there can be some electrical
failures due to defection, corrosion, leaking points on these insulation systems.
Non-grounded conductors in an electrical system, may be a risk for both the system and the people around it. If
all the equipment is connected to each other and to the ground properly, then any leakage on system can flow to
ground through this connection and will not cause any problem.
The grounding must be done in accordance with the related international and local regulations.
The grounding resistance must not be more than 20 Ohms.
The electricity may be harmful for human beings if it is rated more than 15 mA and 50 V.
The electrodes buried to the ground for grounding purposes must be at least 20 meter
away from another electrode.
