A list of organizations represented on this committee can be obtained on request to its secretary. Relationship with other publications BS 8504 is published in two parts: Part 1
8、: Colour, shape and meaning; Part 2: Materials Requirements and test methods. Information about this document The purpose of BS 8504 is to specify a standardized set of beach safety flags. It is important that beach safety flags are standardized to aid their comprehension. Whilst education in the co
9、mprehension of beach safety flags is essential, incomprehension caused by lack of standardization can lead to confusion and possibly danger. International travel increases the need for standardized methods of safety communication. Presentational conventions The provisions of this standard are presen
10、ted in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”. Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element. Contractual and legal considerati
11、ons This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.

27、ty flags A.1General There are two types of beach safety flags, those indicating dangerous conditions and those used to indicate zones on the beach suitable for particular activities (see Table 1). Red flags and orange truncated cones indicate dangerous conditions and should be used singly. In partic
28、ular, care should be taken to ensure that only one red flag is visible on any given beach, or area of a beach, as two red flags could be mistaken for indication of a safe zone, thus putting people at risk. Red and yellow flags should be used in pairs to designate each area along a beach which is mos
29、t closely supervised or patrolled, and to which it is intended that swimming and body boarding is to be confined. The positions of red and yellow flags, indicating a lifeguard patrolled zone, should be designated by a qualified lifeguard. Where a lifeguard patrolled zone is not used, a single red an
30、d yellow flag may be used to indicate that a lifeguard is on duty. This should only be displayed at the lifeguard station, hut or highchair etc. Black and white flags should be used to designate a zone, or the boundary of a zone, on a beach for use of surfboards and other water craft. These flags sh
31、ould be positioned outside of the area designated by the red and yellow flags for swimming and body boarding. NOTEAn example of positioning of red and yellow flags and black and white flags is illustrated in Figure A.1. Licensed Copy: London South Bank University, London South Bank University, Fri D

33、of the flag, when at rest, is not less than 2.3 m above the immediately surrounding ground level. The flag-pole should be securely anchored so as to be stable under the prevailing weather conditions in the area. NOTE 1This may be done, for example, by means of a sand spike or by securing the flag-po
34、le to a stand (for example a tripod or a four-legged stand) or to a solid base. NOTE 2If the flag is secured to a stand, the stand may also be used to display safety information. A.3Positioning of beach safety flags Flags should be positioned so that they can be readily seen by persons on the beach
35、and in the water. Flags should be mounted high enough to be seen above any obstructions. Flags should be positioned so that they are visible without obstruction by other structures or by any flora and fauna that might be present. The locations of flags should be carefully selected to ensure that the
36、 flags themselves, in particular the flag-poles, do not present a hazard. Flags should not be located where a flying flag could hit passers-by, or where the flag-pole could present a trip hazard.

37、ity, Fri Dec 08 06:24:04 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 6 BSI 2006 BS 8504-1:2006 A.4Use of beach safety flags It is essential that the flags are used only when a lifeguard is present. As the environmental conditions can alter from day to day, and in some cases during the course of a day
38、, conditions should be monitored and flags hoisted or taken down accordingly. In the case of flags used to zone a section of beach or water activity, conditions should be monitored and these flags moved to suitable locations as any changes in conditions dictate. Because of the need for a lifeguard t
39、o be present to monitor the conditions, and possibly to change flags, it is essential that the times of day and, where applicable, days of the week and/or months of the year during which beach safety flag systems are operated on a particular beach are well publicized. There should also be a well pub
40、licized warning that when no flags are displayed this means that the beach is not manned by a lifeguard. A.5Inspection and maintenance of flags and flag-poles Inspection and maintenance of flags and flag-poles should be carried out on a regular basis. Flags can have a limited lifespan, particularly
41、in adverse weather conditions. Any flag that has become torn or faded should be replaced. A.6Storage of flags If flags are to be stored, for example at the end of the season, care should be taken to ensure that they are completely dry before they are put into storage. Flags should be stored in dry c
42、onditions away from sources of heat and chemicals. Flags that have been stored should be carefully inspected before they are put back into use. A.7Explanatory text and associated information To ensure water users and members of the public are aware of the meaning of certain flags it might be necessa
43、ry to use text to explain the meaning. The text should either be on a board fixed to the flag-pole, or given on beach safety information boards, positioned, for example, at the entrances to the beach. Use of information boards should be in accordance with RNLI publication A guide to beach safety sig
44、ns, flags and symbols 1 The text should be as brief as possible. It should indicate the primary meaning of the flag when hoisted and give details of the meanings of the flags, their locations and the times during which the beach safety flag system is in operation. If possible the beach operator shou
45、ld arrange for this information also to be included in local information and publicity leaflets for tourists.
