damaged when normal operating procedures are used. In that case, use a DANGER tag. DANGER Tag A DANGER Tag ( 9890/8) is a RED tag, shown in figure 3-7. It is used to prohibit operation of equipment that,  if  operated,  could  jeopardize  the  safety  of personnel  or  damage  the  equipment.  Under  NO circumstances may equipment be operated or removed when it is tagged with a DANGER tag. TAG-OUT PROCEDURES Before you tag out a piece of equipment, be sure that  you  have  your  supervisor’s  permission.  If  the equipment  is  mission-critical,  you  may  also  need permission from your division officer or department head. For  further  information  on  equipment  tag-out procedures,  refer  to  the  Tag-out  User’s  Manual, NAVSEA S0400-AD-URM-010/TUM. Q7.    What  three  situations  discussed  in  the  text require you to tag out equipment? Q8.    Name   two   tagout   responsibilities   of   your department  authorizing  officer  for  tag  out procedures. Q9.    What are the five tag-out documents that you may use in your job as a Fire Controlman? PROTECTIVE EQUIPMENT The wearing of the correct protective equipment is essential  to  all  naval  personnel.  It  is  especially important for the safety of electronics personnel. This section  discusses  basic  electrical  equipment:  safety shoes;  rubber  gloves;  safety  shorting  probes;  eye, hearing,    and    respiratory    protection;    and deck-insulating material. ELECTRICAL SAFETY SHOES You  will  normally  be  issued  a  pair  of  electrical safety shoes when you report to your first duty station. You must wear them whenever you work on or around energized equipment. Take care of them. You can clean and shine them just like regular safety shoes. When they become worn out or damaged, turn them in to your supply division for a new pair. Electrical safety shoes do not have any exposed metal parts like you might find on   regular   safety   shoes.   They   have   special non-conducting soles designed to protect you from a maximum of 600 volts. RUBBER GLOVES Rubber  gloves  are  designed  to  keep  you  from being  injured  when  you  must  or  may  accidentally touch an electrically “live” component. There are four classes  of  rubber  insulating  gloves.  The  primary features of the gloves are their wall thickness and their maximum safe voltage rating. Refer back to table 3-3 for glove classes and the maximum safe voltage for which they may be used. SAFETY SHORTING PROBE Some of the electronic equipment you may work on  will  use  large  capacitors  to  filter  the  electrical power.  You  must  discharge  these  capacitors  before working on the equipment by using a safety shorting probe.  The  procedure  for  using  a  shorting  probe  is provided in table 3-8. 3-10 Block TITLE Description 1 Log Serial The sequential log serial number issued for tag-out actions. 2 Date Issued The date the log serial number was issued. 3 Type The type of tags used, either CAUTION or DANGER. 4 Description The description of the system or component that will be tagged out and any amplifying information. 5 Date Issued/Cleared The date that ALL the tags were cleared.
