12. Eyewash stations are required on all jobsites. Fire  Extinguishers An  adequate  number  of  fire  extinguishers  are required   to   be   on   site.   The   number   required   is determined by the types of extinguisher required to extinguish  the  various  types  of  materials,  such  as paint, corrosives, and other flammables, on the jobsite. Also, the size of the jobsite must be considered, and there must be one extinguisher at each welding station. Refer  to  the  EM  385  for  further  guidance. • Material Safety Data Sheets are required to be on site for all hazardous material. (MSDS will be  discussed  in  this  chapter.) • All high work is serious business. Work above 5 feet in height must be particularly well planned and personnel safety constantly enforced. Scaffolds Accidents   occur   when   high   work   becomes   so routine   that   safety   measures   become   lax   and inspection  of  scaffolds  is  not  performed.  A  healthy respect  for  the  hazards  must  be  maintained. References   (1)   and   (3)   contain   detailed   safety information  on  scaffolds,  and  additional  safety guidance can be found in reference (2). Scaffold safety is also discussed in chapter 6 of this manual. Some of the  more  general  precautions  are  the  following: • • • • • • • • Work  above  5  feet  must  have  scaffolding provided. People  working  above  12  feet  and  not  on scaffolding must have a safety belt and lifeline. Ground personnel must be kept clear of high work. Never  use  makeshift,  expedient  scaffolding. Inspect  scaffold  members  and  equipment  daily before work is started. Keep all members in good repair  without  delay. Do not use scaffolds for storage space. Use  handlines  for  raising  and  lowering  objects and  tools. Do  not  paint  scaffolds  since  painting  can  conceal defects. Welding and Cutting A   significant   part   of   construction   and maintenance/repair  work  is  welding  and  cutting. Safety was addressed in volume 1 of this manual and is addressed here as a part of general on-site safety concerns. Safety precautions required for this work are extensive and specialized. The importance be shown by the extent of guidance on welding safety provided in  references  (1),  (2),  and  (3).  One  point  to  bear  in mind is that welding safety must be concerned with other personnel on the jobsite as well as the people performing the work. A list of some of the more basic precautions  and  procedures  welders  must  be  aware  of or adhere to should include the following: Eye injury. Burns. Toxic  vapors. Electric  shock  (when  applicable). Fire and explosion. All  welding  equipment  should  be  inspected daily.  Remove  the  defective  items  immediately from  service. personnel protective equipment and clothing must be considered an integral part of the work and  must  be  inspected  and  maintained accordingly.  No  compromises  in  the  protection of  welders  is  allowed. Areas should be marked with Danger - Welding and  Eye  Hazard  Area  signs. Welders working above 5 feet must be protected by railings or safety belts and lifelines. When  welding  any  enclosed  space  or  pontoons, ensure that a vent opening is provided and that the  space  is  free  of  flammable  liquids  and vapors. Do  not  weld  where  flammable  paint  or  coating can cause a fire hazard. After welding is completed, mark the area of hot metal  or  provide  some  means  of  warning  other workers. SAFETY  RESPONSIBILITIES Figure 1-7 shows the Battalion Safety Control and Reporting  Organization.  As  a  crew  leader,  you  will report  to  the  safety  supervisor,  who  directs  the  safety program of a project.
