Institutions such as "SG" Inflatable structures

(Rear of 6 Jan 1983)

DIVISION I

General

Art. SG 1 - Institutions subject
1 - The provisions of this chapter apply to structures whose walls and cover are made in whole or in part, supported by a flexible envelope of air introduced under pressure either directly or through frames inflatable and whatever the size of the public received.
2 - The inflatables must not shelter the premises or the following facilities:
- Including performance spaces below or scenery of category M 2, M 3 or M 4;
- Installation of cinema projection using appliances with an arc lamp is not installed in a sealed balloon without gas exchange with the outside.
- Space reserved for sleep;
- Local libraries and archives;
- Classrooms (excluding sports facilities);
- Health facilities;
- Permanent office.
In addition, the inflatable should not house activities involving the presence of a heat potential exceeding 250 MJ/m2 average, or 400 MJ/m2 locally.
3 - The provisions of Books I and II of the safety regulations are applicable with the exception of Articles CO and DF. However, items relating to CO clearances apply.

Art. SG 2 - Calculation of the effective
The maximum permitted public is determined using the method of calculation for each type of activity envisaged for establishments covered. However, the maximum number permissible shall not exceed one person per square meter.

Art. SG 3 - Implantation
1 - The inflatable structures must be located in areas with no risk of ignition fast.
To the extent that these structures can accommodate over 300 people, they should not be separated by more than 200 meters from a water point ensuring a minimum flow of 60 cubic meters per hour for 1 hour at least. If these conditions can not be met, a fire department have sufficient hydraulic means must be established.
2 - A security perimeter, with a minimum width of one meter should be materialized (excluding access) by barriers, ropes, etc.. This area must be accompanied by a prohibition from entering, clearly identified to avoid being undermined the integrity of the structure and its equipment (shell, anchors, tunnels, etc..).
3 - All measures must be taken, particularly when the ground is sloped to ensure stability of the building against various risks (runoff, oil leakage, etc..).
4 - The inflatable structure must be located in more than:
4 meters from another institution if both institutions are common risks; 8 feet of another establishment if one of the two institutions is at particular risk.
These distances are measured horizontally from the foot of the inflatable structure.
If, exceptionally, in certain cases, these conditions can be met, the safety commission determines equivalent isolation measures.
5 - A free passage out of 3 meters wide and at least 3.5 meters in height at least must be on more than half the circumference of the institution.
Two access roads, if possible, opposite, must be provided from the public highway. They must have a minimum width of:
7 meters for Category 1 facilities;
3.5 meters for other establishments.
All vehicle parking is prohibited in these passages. These provisions are not mandatory if the institution receives more than fifty people.



Art. SG 4 - materials and hazardous substances
You may not store or use, even occasionally, of hazardous materials and substances within the meaning of the decree of April 20, 1994 as amended relating to the declaration, classification, packaging and labeling of substances.
It is also forbidden to perform hazardous work while the public is present.

Construction

Art. SG 5 - Scope
§ 1. Rules "Wind" DTU "Snow and wind" are applicable to inflatable structures.
§ 2. Structures must have a single volume. The envelope must be made of materials of category M 2 of which the minutes of reaction to fire classification does not include a limit of sustainability.
Materials not on the list established in Annex II of this chapter are amenable to the accelerated aging tests defined in the order of 21 November 2002 on the reaction to fire performance of construction and development.
When windows are provided, they should be made of materials of category M 3, the surface unit must not exceed 1 square meter, the minimum spacing between two windows should be 5 meters high and must be located 3.50 meters more anchor points.
§ 3. In case of disputes relating to the reaction to fire classification of materials used, the safety commission may require the owner or operator to justify their ranking. However the materials justifying the quality mark "NF - Reaction to fire" are exempt from this rationale.
§ 4. All measures must be taken both by the manufacturer by the operator, for any objects (or interior) can cause a tear of the envelope.
§ 5. The technical installations must be removed from at least 5 meters from the walls of the structure or be isolated from it by a screen of FC degree one hour and must be arranged in a room or a closed volume, outside the inflatable structure.
In all cases, these facilities must be beyond the reach of the public.

SECTION III

Pressurization

Art. SG 6 - General
1 - Pressurization, necessary to maintain the structure, must be ensured:

- Security by a blower;
- By a blower replacement (if necessary).
A blower replacement is necessary for continued operation in case of failure of the normal fan.
2 - The pressurisation shall be ensured by an air supply at least equal to natural leaks. This air supply is provided by two blowers, independent of one another: the normal fan and blower safety.
Two fans must always be in working order.
3 - If off blower normal, and in the absence of a wind tunnel replacement, the operator must remove the public if the blower is not normal return to service after ten minutes.

Art. SG 7 - Pressure Gauge
All inflatables must be equipped with a pressure gauge to see a drop in pressure:
- Or within the structure;
- Either in the inflatable reinforcement.
In addition, an alarm system shall prevent the head of the establishment of any abnormal pressure drop.

Art. SG 8 - Led blowers
Each group of pressurization must be connected to the structure formed by a flexible conduit materials in category M2 and equipped, at the outset:
- A check valve;
- A degree of valve CF half hour with fuse (to avoid the possible transmission of fire to the structure). However, this provision is not mandatory for institutions receiving more than fifty people.

Art. SG 9 - Blower Safety
1 - The tunnel safety must be operated by an independent power source, independent of that used for normal wind tunnel, and with an operating time of one hour.
2 - In case of failure of the blower normal or abnormal pressure drop, the wind tunnel security must be put into operation:
- Automatically, in a time not exceeding one minute;
- Manually, in case of failure of the previous system, the intervention of personnel and within five minutes.
3 - In addition, staff must be able, if required (tearing of the envelope for example), run in parallel the normal fan and blower safety.

Art. SG 10 - Storage of liquid or liquefied hydrocarbons
§ 1. In the event that an aboveground storage of hydrocarbons is necessary either to ensure the normal operation of heating or pressurization, or to ensure the proper functioning of safety equipment, it must be removed from at least 5 meters structure and be protected by fencing effective.
§ 2. The storage of liquid hydrocarbons must have a retention tank with a capacity at least equal to the total stored flammable liquids.

Art. SG 13 - Evacuation
1 - The manufacturer and the operator must prove by calculation that the evacuation time is less than the time of bursting of the structure.
2 - deflation time is determined from the following:
- Only the wind is back in service;
- All outputs are open doors;
- The casing comprises a tear 1 to 1000 of its surface.
Deflation is assumed reached when the volume of residual air corresponds to a vertical clearance of 3.50 meters on the fourth of the floor, this volume remains accessible by at least one protected area.
3 - The time of detection and transmission of the alarm being set flat rate of three minutes, add an evacuation time calculated on the basis of 30 persons per minute per unit of way is assumed that a quarter of units passage is unavailable.
4 - If the number admitted led to an evacuation times greater than the time of deflation, it should:
