If you have visited a shooting range at least once in your life, so you probably remember the pungent smell of gunpowder, which intensifies with each new shot?
The room where the shooting range is located is often airtight and soundproof. This helps to muffle loud gunshots and prevent combustion products from escaping, but visitors feel heat and suffocation when moving.
A high-quality and efficient ventilation system is needed so that after half an hour of being indoors, the well-being of customers will not get worse due to the lack of fresh air and the presence of harmful substances in the air.
According to sanitary regulations, such premises must necessarily be equipped with a supply-exhaust mechanical ventilation system.
Therefore, when designing the ventilation of shooting ranges, it is necessary to be guided by the calculations of maximum permissible concentrations of harmful substances in the firing zone of the shooting range that are established by the state.
According to the rules, in closed and semi-closed shooting ranges (those with a wall between the shooting gallery and the firing zone) it is necessary to provide a system of supply-exhaust mechanical ventilation.
The rate of air exchange in such rooms according to the established norms depends on the characteristics of the shooting range. For the firing zone of a closed shooting range and a shooting gallery, the air inflow is set based on the calculation of exhaust compensation, the leakage is calculated according to the norm of 600 m3/h per shooting place in small-caliber shooting ranges and 1200 m3/h per shooting place in large-caliber shooting ranges weapons.
Fresh air in such rooms should be supplied in the upper zone of the shooting gallery from the side of the end wall (which is located behind the firing line) along its entire width.
Air removal in closed shooting ranges occurs through exhaust holes, which must be placed under the ceiling of the firing zone 4-6 meters in front of the firing line (2/3 of the total volume of air to be removed) and at the bottom of both side walls at a distance of 2 m from line of fire (1/3 air removed).
Through exhaust holes placed in front and on the side of the firing line, smoke and gas from shots are removed not only from the firing zone, but also from the area of the firing line.
It is not recommended to arrange an air exhaust inside or at the end of the firing zone in closed shooting ranges because in this case smoke and gases can spread throughout the firing zone and with intense shooting a kind of fog will form that will impair the visibility of targets.
In shooting ranges where shooting is carried out from several firing lines (for example, in a large 100-meter shooting range there may be five firing lines), the hood should be mounted separately in front of each line of fire. At the same time, it is necessary to ensure the possibility of switching extraction zones in accordance with the place of shooting.
All utility rooms have sufficient ventilation, similar to ordinary living quarters.
One of the best options for organizing the necessary air exchange in the shooting range today is the installation of ventilation from the Prana company.
Installation of recuperators will ensure:
- high-quality ventilation of the room 24 hours a day;
- effective removal of polluted air from the premises;
- removal of unpleasant smells;
- reduction of energy consumption;
- convenient control from the remote control and smartphone;
- constant monitoring and analysis of air quality (in ECO series systems).x
The useful function of separate control of inflow and extraction will allow to adjust the air quality in real time and so ensuring the safety and comfort of shooting range visitors.
In order to choose the best solution, before purchasing the equipment, you should contact the project department of the Prana company.
Qualified engineers of the company will offer the best possible ventilation solution, recommend the necessary equipment or they will design an individual solution of the ventilation system.
