(a) Before starting the performance the hypnotist shall make a statement to the audience, in a serious manner, identifying those groups of people who should not volunteer to participate in it; explaining what volunteers might be asked to perform; informing the audience of the possible risks from embarrassment or anxiety; and emphasising that subjects may cease to participate at any time they wish. The following is a suggested statement, which might be amended as necessary to suit individual styles as long as the overall message remains the same:
"I shall be looking for volunteers aged over 18 who are willing to be hypnotised and participate in the show. Anyone who comes forward should be prepared to take part in a range of entertaining hypnotic suggestions but can be assured that they will not be asked to do anything which is indecent, offensive or harmful. Volunteers need to be in normal physical and mental health and I must ask that no one volunteers if they have a history of mental illness, or are under the influence of alcohol or other drugs or are pregnant."
(b) No form of coercion shall be used to persuade members of the audience to participate in the performance. In particular, hypnotists shall not use selection techniques which seek to identify and coerce onto the stage the most suggestible members of the audience without their prior knowledge of what is intended. Any use of such selection techniques (e.g. asking members of the audience to clasp their hands together and asking those who cannot free them again to come onto the stage) should only be used when the audience is fully aware of what is intended and that participation is entirely voluntary at every stage;
(c) If volunteers are to remain hypnotised during an interval in the performance, a reasonable number of attendants as agreed with the licensing authority shall be in attendance throughout to ensure their safety;
