ANSWERS TO CHAPTER QUESTIONS

to  require  hearing  protection,  err  toward  the  side  of safety. Protect your hearing! RESPIRATORY PROTECTION It is very important to use the proper respiratory protection when you use hazardous paints, solvents, and  other  materials  associated  with  cleaning  and maintaining  electronic  equipment  and  antennas.  Be sure  to  ask  your  supervisor  about  the  need  for respiratory protection whenever you ·   chip  lead-  or  chromate-based  paints  while removing corrosion, ·   prime or paint the bases of antennas, or ·   clean circuits with spray solvents or alcohol. Whenever  you  perform  these  operations,  be  sure that the work area has good ventilation. This will help prevent you from over-inhaling hazardous vapors and dusts. DECK-INSULATING MATERIAL Your   working   environment   should   have deck-insulating  material  (more  commonly  called rubber  matting)  to  protect  you  and  your  shipmates from electric shock. It must be installed wherever work is   done   on   energized   electrical   and   electronic equipment. This includes electronic repair shops that have   workbenches   for   working   on   electronic equipment. The rubber matting should be rated for use in areas where  the  maximum  voltage  will  not  exceed  3,000 volts. It must be installed in one continuous run, at least 36 inches wide, and must extend at least 24 inches past each end of the workbench. If  you  must  work  on  energized  equipment  in  an area  where  rubber  matting  is  not  installed,  protect yourself from electric shock by using a 6-foot piece of rubber matting as a portable safety deck. When you are done, roll it up and store it for the next job. Rubber matting does a great job of protecting you from electric shock, but it will not protect you for long if you do not take care of it. The  following  tips  will  help  keep  the  insulating properties of rubber matting intact: ·   Keep rubber matting clean and free of any excess dirt, oil, or oil-based products. When you clean it,  do  NOT  use  abrasive  cleaners  or  electric buffers;   they   will   ruin   its   insulating effectiveness. ·   Inspect  the  rubber  matting  for  cuts,  cracks,  or excessive wear periodically. If you notice any of these conditions, replace it entirely. Q10. Name  four  types  of  personal  protective equipment  associated  with  working  with electricity. SUMMARY Throughout  your  training  you  have  been  taught about electrical and electronic safety. This chapter has attempted to give you an overview of this area of safety. However, one of the greatest dangers in this area is not your lack of knowledge but the complacency you may develop from hearing the same message over and over. You  know  these  safety  standards;  they  have  been drilled into your thinking. You may have even taught this material to someone at some time in your career. DO  NOT  ALLOW  A  COMPLACENT  ATTITUDE TO  KILL  YOU! Although  voltage  is  normally mentioned  in  talks  about  electrical  shock,  you  must remember that current is what will kill you. As little as one-tenth of one ampere (0.1 ampere) of current can be fatal.  The  majority  of  shock  fatalities  are  related  to voltages less than 120 volts. Even lesser voltages can be fatal because of the relative current flow. Treat all voltages as life threatening. In view of the potential harm of electrical shock, the  tag-out  system  was  implemented  for  your  safety. Do  not  take  anything  for  granted  when  tagging  out equipment. Make sure everything is done by the book and that you and your fellow FC’s are safe. Do not be in such  a  hurry  that  you  use  short  cuts  in  tagging equipment  out  or  in  using  protective  equipment.  Do not adopt the attitude that it’s “the other guy” who gets killed  or  injured  when  using  “short  cuts.” Read, study,  and  know  what  your  command  requirements are  for  tagging  out  equipment  and  checking  out protective gear. Take  the  knowledge  offered  in  this  chapter  and apply it to your everyday job. Remember, SAFETY FIRST! 3-14
