Crystalline silica – general fact sheet (Korean)

결정형 실리카- 일반 정보 자료

Silica dust is a hazard when inhaled into the lungs. This fact sheet helps you manage the risks.

실리카 먼지는 폐로 흡입할 경우 위험을 초래합니다. 이 정보 자료는 위험 관리에 도움을 줍니다. 

What is crystalline silica?

결정형 실리카란 무엇인가요?

Crystalline silica is a naturally occurring mineral found in most rocks, sand, clay, and in some manufactured products such as bricks, concrete, tile and engineered stone. In its stable solid form, crystalline silica is not harmful.결정형 실리카는 대부분의 암석, 모래, 점토 및 벽돌, 콘크리트, 타일, 인조 석재와 같은 일부 제조품에서 발견되는 천연 광물입니다. 안정된 고체 형태의 결정형 실리카는 해롭지 않습니다.

Where is crystalline silica used?

결정형 실리카는 어디에 쓰나요?

Crystalline silica is a very common mineral used in manufacturing building products and construction materials. Manufactured materials containing silica include fibre cement sheets, bricks, tiles, and cement. Workers can also come across crystalline silica when undertaking construction works that require excavation or tunnelling through quartz containing rocks such as shale and sandstone.결정형 실리카는 건축 자재 및 건축 재료 제조 시 매우 흔하게 사용되는 광물입니다.  제조 시 실리카가 포함된 자재로는 섬유 시멘트 시트, 벽돌, 타일, 시멘트 등이 있습니다. 건설 작업 중 셰일 및 사암과 같은 석영 함유 암석을 굴착하거나 터널 공사를 할 때에도 결정형 실리카를 발견할 수 있습니다.

How can crystalline silica harm workers?

결정형 실리카는 어떻게 근로자에게 해를 끼칠 수 있나요?

Very fine particles of crystalline silica dust present a hazard when inhaled into the lungs. Airborne dust is most likely to occur when materials or products containing silica are cut, sanded, drilled or any other action (task) that creates fine dust. Exposure to RCS dust can have serious health effects depending how much dust a worker breathes in and for how long.  These health effects can include:

  • silicosis – a scarring of the lung which can result in a severe shortness of breath and is not reversible. Severe cases can result in complications leading to death
  • lung cancer
  • kidney disease.

Applying risk controls such as minimising the generation of airborne silica dust can reduce hazardous exposures and prevent illness in the workplace.

매우 미세한 결정형 실리카 먼지는 폐에 흡입될 경우 위험을 초래합니다.  실리카를 포함한 자재를 절단, 샌딩, 드릴링하거나 미세 먼지를 생성하는 기타 작업을 할 때 공중에 먼지가 퍼질 가능성이 높습니다. 근로자가 얼마나 많은 먼지를 얼마나 오랫동안 흡입했는지에 따라 RCS 먼지 노출은 심각한 건강 문제를 초래할 수 있습니다.   이러한 건강 문제에는 다음이 포함됩니다.

  • 실리코시스- 폐에 흉터를 남겨 심각한 호흡 곤란을 초래하며 돌이킬 수 없습니다.  심각한 경우 합병증으로 인해 사망에 이를 수 있습니다
  • 폐암
  • 신장 질환.

공기 중 실리카 먼지 발생을 최소화하는 위험 통제를 적용하면 유해한 노출을 줄이고 작업장에서 질병을 예방할 수 있습니다.

How to protect yourself and workers

본인과 근로자를 보호하는 방법

  • Any worker involved in high-risk silica work activities or workers who may be at risk of exposure to RCS because of that work activity must complete an approved crystalline silica training course
  • Provide all workers with information and instruction on how to work safely with silica products in the workplace
  • Eliminate tasks that generate dust where possible
  • Apply water suppression systems to reduce dust generation
  • Use local exhaust ventilation systems to capture and remove dust at the source
  • Use dust capture systems on portable tools
  • Instruct workers in the correct use, selection, fit, and maintenance of respiratory protective equipment
  • Avoid using compressed air to remove or clean settled dust
  • Avoid dry sweeping where possible
  • Follow instructions and controls outlined in safety data sheets and product labels
  • 고위험 실리카 작업 활동에 참여하거나 이러한 작업 활동으로 인해 RCS 노출 위험이 있는 모든 근로자는 승인된  결정형 실리카 교육 과정을 완료할 것
  • 근로자에게 작업장에서 실리카 제품을 안전하게 취급하는 방법에 대한 정보와 지침 제공하기
  • 가능한 경우 먼지 발생 작업 없애기
  • 먼지 생성을 줄이기 위해 물 억제 시스템을 적용하기
  • 먼지를 원천에서 포착 및 제거하는 국소 배기 환기 시스템 사용하기
  • 휴대용 연장의 먼지 포착 시스템 사용하기
  • 호흡 보호 장비의 올바른 사용, 선택, 착용 및 유지 관리 방법에 대해 근로자 교육
  • 가라앉은 먼지를 제거하거나 청소하는 데 압축 공기 사용하지 않기
  • 가능하다면 건조 청소 피하기
  • 안전 데이터 자료 및 제품 라벨에 명시된 지침 및 통제 따르기

Monitoring requirements

모니터링 의무 사항

  • Health monitoring must be provided for workers who are involved in any ongoing work that creates RCS dust, even if respiratory protection is used to control exposure
  • Air monitoring must be undertaken when:
    • it is necessary to determine if workers are at risk from exposure to RCS, or
    • you’re unsure if the amount of airborne RCS at the workplace exceeds the Workplace Exposure Standard (WES) levels.
  • RCS 먼지를 생성하는 지속적인 작업에 참여하는 근로자에게는 호흡 보호 장비를 사용해 노출을 통제하더라도 건강 모니터링을 제공해야 합니다
  • 다음과 같은 경우 공기 모니터링을 반드시 실시해야 합니다.
    • 근로자가 RCS 노출로 인해 위험에 처했는지 확인할 필요가 있는 경우
    • 작업장 공기 중 RCS 양이 작업장 노출 기준(WES)을 초과하는지 확실하지 않은 경우.
