Excavation Safety (굴착공사 안전)

건축물/구조물의 시작은 기초부터 입니다.

기계/기구/장비 등에도 Foundation = 기초공사가 필요하구요.

그래서 토목담당하시는 분들은 자부심이 있으시더라구요.

우리가 땅속에 무엇이 있는지 모르고 굴착작업을 시작합니다.

현장 지장물 도면 및 기본조사를 통해 자료를 수집하지만 그럼에도 불구하고 많은 사건/사고가 일어나고 있습니다.

굴착공사는 대부분 건설기계를 동원하여 작업하기 때문에,

지장물에 따른 사고 외에도 공사중 과실로 인하여 발생합니다.

아래 자료는 굴착공사에 대한 특별안전교육자료로 이해하시면 되며,

바로 근로자 안전교육자료로 활용하실 수 있게끔 작성하였습니다.

(개인적인 생각입니다;;)

이해하기 편하게 작성했다고 생각하는데~ 

좋은 의견과 자료가 있어서 공유되면 더욱 좋겠습니다.

[Potential Hazards]

  • Fires, Explosions and Electrocutions due to utility hits
  • Struck by falling objects
  • Falls and Equipment rollovers
  • Cave-ins
  • Asphyxiation, Toxic exposures, and explosions due to hazardous atmospheres
  • Leading to property damage, injury and death

 

[Statistics]

Excavation Statistics

  • About 400 workers die in trench related accidents each year in U.S.
  • About 6,400 are seriously injured
  • About 140 result in permanent disability

 

[Definition]

 

[Preplaning]

▶ It is important to approach each new job with the utmost care and preparation

▶ Many on-the-job accidents result directly from inadequate initial planing

▶ No matter how many trenching, shoring, and backfilling jobs you have done in the past

 

[Underground Utility]

 

[Prior to Works]

 

[Protective System]

♦ Sloping or benching the sides of the excavation

♦ Supporting the sides of the excavation

♦ Placing a shiedl between the side of the excavation

 

[Soil Classification]

[Falling Objective]

  • All materials are kept away at least 1.0 m from the edge of the excavation

[Water Accumulation]

  • Use of water removal equipment by a competent person
  • Use of diversion ditches, dikes, or other suitable means from entering
  • Adequate drainage of the adjacent area
  • A competent person must inspect exvacations subject to runoffs from heavy rains

 

[Hazardous Atmosphere]

[Access & Egress]
