    Safe Work
     Practices

                 1
  HAZWOPER
Management of site should include
 development of Standard Operating
 Procedures (SOPs) to maintain strong
 safety awareness and enforce safe
 procedures

  Examples of SOPs

        No smoking, eating, drinking in this “zone”
        No matches or lighters in this “zone”
        Check in at the entrance Access Control Point before
         you enter this “zone”                                  2
HAZWOPER
 Examples (cont.)
       Check out at the exit Access Control Point before you
        leave this “zone”
       Always have your buddy with you in this “zone”


 All who enter this site should be knowledgeable
   of these SOPs, as well as needed Hazardous
   Substance Information Forms




                                                          3
HAZWOPER
Walking and Working Surfaces—concern
 about injury due to slips, trips or falls
        Openings—need for proper guarding, railings or
         coverings
        Stairs—adequate construction for anticipated loads,
         adequate widths and angles, slip-resistant, guarded by
         railings
        Ladders—proper, not makeshift; inspected to be free
         of defects; proper climbing technique and not
         overreaching; proper angle of set-up; hoist tools, etc.,
         after reaching top; no standing on top of step ladder


                                                             4
HAZWOPER
     Scaffolds—inspected daily; free of ice, snow, slippery
      materials; caution against overloading; casters or
      mobile units locked; fall-protection devices operable




                                                         5
HAZWOPER
Overhead and Underground Utilities
     Underground Utilites
          In most states, calling the utility before digging is
           required
          Utility companies will locate and mark cables and
           pipelines as prevention of accidental severing of
           cables




                                                                   6
HAZWOPER
Overhead and Underground Utilities
     Overhead Utilities
          Overhead power lines are the greatest above-ground
           utility hazard
               Via electricity arcing or jumping from line to individual
                in close proximity
               Via contact with power line while individual is carrying a
                conductive piece of equipment




                                                                       7

Overhead and Underground Utilities
     Overhead Utilities
          Prevention of accidents (electrocution)
               No conductive jewelry
               Establish minimum clearance distances for workers
               Establish insulating barriers to protect against direct
                contact with overhead lines
               PPE to protect against electric shock and flash or fire
                from arcing




                                                                     8
HAZWOPER
Overhead and Underground Utilities
     Overhead Utilities
          In case of electric shock of co-worker:
               Protect yourself from electrocution
               Shut off power
               If shutting off power not possible, pry or knock victim
                free with nonconductive object
               DO NOT ATTEMPT to pull victim away by hand
               Call for medical assistance
               Administer CPR or defibrillation




                                                                     9

Tools and Heavy Equipment

     Major hazards at waste sites. Require proper
      maintenance and inspections:
          To see that parts are secured and intact
          To see that equipment turns smoothly
          To see that equipment is operating within
           specifications
               (Brakes, hydraulic lines, light signals, fire extinguisher,
                fluid levels, steering, splash protection)



                                                                       10
HAZWOPER
Energy Sources

     Lockout/Tagout

          Mandated in 29 CFR 1910.147
          Procedures protect worker from accidental start-ups
           of equipment and from electric shock




                                                           11
HAZWOPER
Energy Sources

     Lockout

          Process of blocking flow of energy from power source
           to piece of equipment and keeping it blocked
          Device is a lock, block or chain that keeps a valve or
           lever in the “off” position




                                                             12
HAZWOPER
Energy Sources

     Tagout

          Placing a tag, or notice, on the power source as a
           warning not to restore energy.
          Tags must clearly state: “DO NOT OPERATE” and
           must be applied by hand




                                                            13

HAZWOPER
Heavy Loads

     Ergonomics

          Arranging the work environment for an individual’s
           body requirements
          Risks of accidental musculo-skeletal and cumulative
           trauma disorders (as tendonitis and carpal tunnel
           syndrome)



                                                             15
HAZWOPER
Special Case Problems

     Vacuum trucks
          Wear appropriate clothing
          Use mobile steps or suitable scaffolding instead of
           walking across truck catwalk
          Use carriers for equipment and samples to allow
           freedom of hands for stability
          Sample from top of vehicle, not drain spigot—to avoid
           possible spraying of excessive substance


                                                            16

                                                              22
HAZWOPER
Handling Drums and Other Containers

     Monitoring, as with gamma radiation survey
      meter, organic vapor monitor, and combustible
      gas meter

     Personnel should assume unlabeled drums are
      hazardous, and may be mislabeled



                                                 23
HAZWOPER
Handling Drums and Other Containers

     Buried drums
          Ground penetrating systems can be used to locate and
           estimate depth of burial




                                                           24
HAZWOPER
Handling Drums and Other Containers

     Handling may be necessary . . .

          To respond to problems, as radioactivity, leakage, or
           presence of explosives
          To unstack and orient for sampling
          To organize into different areas on site to facilitate
           characterization and remedial action



                                                              25

       **NOTE POSSIBLE NEED FOR OVERPACKS AND
         DIKES IN CASE OF LEAKS AND SPILLS**




                                                26
HAZWOPER
Handling Drums and Other Containers

     Special cases:
          Radioactive waste—handled by authorized personnel
           only
          Explosive or shock-sensitive waste needs special care
          Bulging drums—move only if necessary with special
           equipment




                                                             27
HAZWOPER
Handling Drums and Other Containers

     Special cases (cont.):
          Laboratory packs—assume possible explosion hazard
                Before handling or transporting, move all non-essential
                 personnel away
                Use grappler unit constructed for handling explosives
                Maintain communications with Site Safety Officer
                Once opened, chemist should inspect contents to classify and
                 segregate as needed. Then, new lab packs created and shipped
                 to approved disposal facilities
                If crystalline material is noted on neck of bottles, treat as
                 shock-sensitive (e.g., picric acid)


                                                                         28
HAZWOPER
Leaking, Open, and Deteriorated Drums

     If drum cannot be moved without rupture,
      transfer contents to second drum with pump
      appropriate for liquid. If liquid may be
      explosive, use explosion-proof chemically-
      resistant pump. “Ground” and “bond” drums to
      prevent static charge build-up.



                                                29
HAZWOPER
Leaking, Open, and Deteriorated Drums

     If drum can be moved without rupture or
      spillage, place in overpack. Take care not to
      splash contents onto personnel
