Many venues require a DJ / entertainer to have their own P.L.I. because they do not want their insurance claimed against in the event of a disco related accident such as a client or their guest tripping over a speaker cable or stands falling on a guest, etc. This indemnifies the venue in the event of an accident claim on the premises should it involve the disco equipment. Although venues can insist on the degree of P.L.I. required, the level of P.L.I. will vary from venue to venue.
