まとめ

オーストラリアの職場での溶接煙の曝露は,しばしば新しい基準を超えています. 換気や呼吸器の保護などの対策は十分に活用されていないため,労働者の安全を大幅に改善する必要があることが示されています.

科学分野:

労働衛生と安全
産業衛生について
環境科学

背景:

溶接の煙は労働者に重大な健康リスクをもたらします.
現在の被曝レベルと制御措置の有効性を理解することは,リスク管理にとって極めて重要です.

研究の目的:

オーストラリアの職場における溶接煙の粒子とガス被曝レベルを評価する.
通気と呼吸器の保護を含む対策の利用と効果を評価する.

主な方法:

オーストラリアの20の職場で,溶接煙の微粒子とガスのための個人および静的な空気サンプリングを実施した.
現存する制御措置と作業慣行を文書化するために,職場の観察を行った.

主要な成果:

溶接煙の粒子の総濃度は,1 mg/m3の職場曝露基準を超えました.
オゾン濃度のピークは,多くの労働者にとって0.1ppmの制限基準を超えました.
活発な換気はめったに使われず,主に自然換気を使用した.
呼吸器保護装置の使用は最適ではなく,約25%の溶接工は保護具を使用しなかった.

結論:

この研究は,オーストラリアの職場における溶接煙とガス曝露に関する最初の包括的なデータを提供します.
労働者の被曝を減らすために効果的な対策を実施し,維持するには,大きな改善が必要である.
溶接煙の曝露を制御し,労働者の健康を守るために強化された戦略の必要性を強調しています.

PPE Use in Healthcare Settings II: Doffing

1.1K

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Atomic Fluorescence Spectroscopy

496

Atomic fluorescence spectroscopy (AFS) is an analytical technique that involves the electronic transitions of atoms in a flame, furnace, or plasma being excited by electromagnetic (EM) radiation. When these atoms absorb energy, they become excited and subsequently release energy as they return to their original state. This emitted light, or "fluorescence," is observed at a right angle to the incident beam. Both absorption and emission processes transpire at distinct wavelengths, which...

Flame Photometry: Overview

797

Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...

PPE Use in Healthcare Settings I: Donning

1.3K

Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Atomic Emission Spectroscopy: Interference

271

In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...

Types of Toxins

2.0K

Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...
