However, where a traditional "pole" marquee is to be erected on uneven ground, a solid door frame arrangement may not be suitable as the frame may become distorted and result in the door jamming. Alternatives are to provide a suitable single-action opening device or a Velcro fastening. The latter, under reasonable pressure, can allow the whole wall to open back, providing a wide exit for all present.
The main criteria are, however, that the fastening is suitable for the occupant capacity, is capable of being opened by one simple action requiring no manual dexterity, and is such that people can easily and immediately escape.
The width of any final exit in relation to the number of occupants who may have to use it can be determined by the following table:-
The minimum clear width of exit.
Suitable for not more than:
1.1m 160 persons.
1.65m 240 persons.
1.95m 320 persons.
Enclosures intended to hold more than 50 persons should in no case have fewer than two exits.
From any part of an enclosure having more than one exit:
a) the travel distance to the nearest exit should not be more than 18 meters and
b) after the first 6.5m, the remainder of the route should lead in a different direction from the route of any alternative exit.
In enclosures having only one exit, the travel distance should not be more than 6.5m.
Where enclosures are intended to hold more than 50 persons, an alternative allowance should be made for the fact that one exit may be obstructed and not available because of fire or smoke or another hazard.
At least one exit in excess of the number required by the above paragraphs should be provided; exits should be evenly distributed around the structure so that genuine alternative routes are available from all parts.
All gangways and exits from tents should be kept well clear of obstruction.
Exits should be clearly indicated.
Door flaps when down should hang loose and open outwards by parting in the center of the doorway. Flaps should not trail on the ground.
Where windy conditions make it necessary to keep door flaps down or loosely tied, an attendant should be permanently on duty at each exit to open flaps in an emergency at all times when the public is present.
The line of exit between the tent and the peg line should be fenced.
Seating.
There should in all cases be an unobstructed seat way or space at least 300mm measured between perpendiculars between the back of one seat and the front of the seat immediately behind.
The number of seats in a row should not exceed:-
a) seven seats where there is a gangway at one end only, providing that longer rows up to 11 seats may be allowed, subject to the seat way being increased by 25mm for each seat over 7, and
b) fourteen seats where there is a gangway at each end, providing that longer rows up to 22 seats with a gangway at each end subject to the seat way being increased by 25mm for each additional seat or pair of seats over 14.
Seats in an enclosed structure holding more than 30 people should either be securely fixed in position or rigidly linked together in rows of not fewer than 4 seats. Where on a sloping platform, seats should be fixed in position.
Gangways.
Gangways should be of sufficient width for the seats or area served but not wider than the exits to which they lead. A gangway should not be less than 1.1m in width (i.e. minimum exit width).
5.6 Fire Fighting Equipment Portable fire fighting equipment should be provided throughout the site. Guidance on the suitability, siting, and maintenance of portable fire extinguishers can be found in B.S. Code of Practice 5306: Part 3.
Where a piped water supply is laid on at the site and taps are fitted, a length of small bore hose with a suitable adaptor and nozzle at each tap will also provide a useful means of fighting small fires.
Any natural water sources or static supplies which can be used should be clearly marked to assist the Fire Brigade.
Equipment is best kept at fire points situated on main access lanes. Fire points must be conspicuous and notices should be posted explaining in concise terms how to use the equipment. In large work areas, fire equipment should be placed near to exits.
Fire Procedure.
Every enclosed structure should have a sufficient number of persons in attendance to direct the public to safety in the event of an emergency. One person should be nominated to be in charge of the structure. All persons in attendance should be instructed in their duties in case of fire or another emergency.
In addition to the person in charge of the structure, the number of attendants should be:-
(i) 1 per 250 persons or part thereof over the age of 16.
or
(ii) 1 per 75 persons or part thereof under the age of 16.
Staff should be instructed on the following:-
(i) How to call the Fire Brigade.
(ii) How to evacuate tents in an orderly manner and in the shortest possible time.
(iii) How to attack a fire with the equipment provided whilst awaiting the arrival of the Fire Brigade.
