Kiwi Health and Safety manual for prostitutes
`In situations where more than one worker is providing service to a client (e.g. threesomes) it is necessary to ensure that equipment such as vibrators and dildos is not used by one person and then another without being cleaned, disinfected and having a new condom put on first. Ideally each worker should have her/his own toys and equipment, which are not used by other workers. Each worker may choose to use a condom of a different colour in order to identify who has used the dildo last.’
