NOTE:   The   use   of   ultraviolet   light,   form- aldehyde   tablets, and  materials  capable  of releasing  formaldehyde  into  the  air  is  not authorized  for  use  in  ships’  barbershops. WET  DISINFECTANT A wet disinfectant is a receptacle for holding a  disinfectant  solution  in  which  objects  to  be sanitized are completely immersed. It is used for nonmetallic  instruments  such  as  combs.  A barbicide  or  marvicide  solution  is  used  to  disinfect tools. DISINFECTING  CABINET The  disinfecting  cabinet  is  used  for  holding sanitized  clipper  heads  and  other  metallic instruments  that  have  been  disinfected  with Clippercide  Spray  4-in-1  Formula  or  an  equivalent spray  after  each  use.  Remember,  the  equivalent spray must be approved by the EPA and have an EPA  registration  number. CLEANING  AND  DISINFECTING INSTRUMENTS Instruments coming in contact with the cus- tomer  need  to  be  sanitized  before  reusing.  This includes   blades,   shears,   combs,   and   so   forth, which should be thoroughly washed in hot, soapy water  to  remove  film,  oil,  and  debris,  followed by  placing  the  combs  and  other  nonmetallic instruments in the wet disinfectant. The medical department  determines  the  frequency  for  changing the solutions in the wet disinfectant; normally, it should  be  done  at  least  twice  weekly  or,  if  the workload  requires,  on  a  daily  basis.  Combs disinfected  in  the  chemical  solution  should  be disinfected for at least 20 minutes between uses. They should be rinsed in running potable water to remove any chemical residue before using them. Clipper  blades  and  other  metallic  instruments must  be  dusted,  wiped  thoroughly,  disinfected with  a  commercial  disinfectant  sprayed  after  each use,   and   placed   in   the   disinfecting   cabinet immediately.   Use   commercial   spray   products according  to  the  manufacturer’s  instructions  on the  labels.  Do  not  use  any  formaldehyde  or formaldehyde   producing   products. QUANTITY  OF  EQUIPMENT To  accomplish  proper  sanitation  and  allow  the barber to have adequate numbers of instruments and   supplies,    each   barber   should   have   the following   equipment: Clipper  blades,  three  sets  of  three,  each  set containing one size each of #000, #1, and #1 1/2 Seven  combs  of  various  design Three  pairs  of  scissors Two  pairs  of  thinning  shears Two flatttop brushes Six  hairclips  (3  to  4  inches  long) Fifteen  styling  brushes  (women) SANITARY   PRACTICES The  following  sanitation  regulations  should  be followed  in  the  barbershop: Only   FDA-approved   tonics,   lotions, bleaches,  dyes,  and  so  forth,  will  be  used.  Only EPA/FDA disinfectants or sanitizing agents will be   used.   Questionable   or   unlabeled   products should be referred to the medical department for determination  of  suitability. Therapeutic   practices,   such   as   treating pimples,  ingrown  hair,  and  so  forth,  are prohibited. The   headrest   of   barber   chairs   will be  covered  with  a  clean  sheet  of  paper  or  clean towel  for  each  customer. Only  types  of  material  approved  by  the medical  officer  will  be  used  to  stop  the  flow  of blood in case of “nicks.” These materials will be applied  only  with  freshly  laundered  towels  or sterile  cotton. The  treatment  of  eye  conditions  is prohibited. Common  brushes,  dusters,  and  shaving mugs  are  prohibited.  The  use  of  automatic  dis- pensers  or  brushless  shaving  cream  and  clean towels,   instead   of   brushes   or   dusters,   is recommended. 4-6
