石綿作業：
你必須知道的職業危害 Asbestos Work:
The Occupational Hazards You Must Know

石綿纖維的危害，來自於它的微小尺寸和生物持續性。它能輕易穿過呼吸道防禦，深植在肺部，並在體內存留數十年，引發一系列不可逆的疾病： The danger of asbestos fibers comes from their microscopic size and biopersistence. They can easily bypass the respiratory defenses, embed deep in the lungs, and remain in the body for decades, causing a series of irreversible diseases:

• 石綿肺症：肺部組織會被僵硬的疤痕組織取代，導致呼吸困難、乾咳，最終可能引發呼吸衰竭。Asbestosis: Lung tissue is replaced by stiff scar tissue, leading to shortness of breath, a dry cough, and potentially respiratory failure.
• 惡性間皮細胞瘤：這是石綿暴露的「指標性癌症」，一種罕見且預後極差的癌症。它的潛伏期極長，可能在暴露後30-40年才發病。Malignant Mesothelioma: This is the “hallmark cancer” of asbestos exposure, a rare and aggressive cancer with a very poor prognosis. It has an extremely long latency period, possibly developing 30-40 years after exposure.
• 肺癌：石綿會顯著增加罹患肺癌的風險，特別是吸菸會使其風險呈幾何級數增加。Lung Cancer: Asbestos significantly increases the risk of lung cancer, and this risk is multiplied exponentially for those who smoke.

過去，石綿風險主要來自製造業。現在，風險已轉移到對現有含石綿材料的「擾動」，以下這些是特別需要注意的： In the past, asbestos risk was mainly in manufacturing. Now, the risk has shifted to the “disturbance” of existing asbestos-containing materials. The following occupations require special attention:

• 營建、拆除與裝修業：拆除老舊建築的屋頂石綿瓦、牆面、或移除管線保溫層時，會釋放出大量纖維。特別是使用動力工具切割或破碎時，危害最大。Construction, Demolition, and Renovation: Removing old asbestos roof tiles, wall panels, or pipe insulation releases large amounts of fibers, especially when using power tools for cutting or breaking.
• 造船與修船業：在老舊船隻的引擎室、鍋爐間維修或拆解，可能接觸到用於隔熱的石綿材料。Shipbuilding and Repair: Maintenance or dismantling in the engine rooms and boiler rooms of older ships can lead to contact with asbestos insulation materials.
• 汽車維修業：在處理老舊車輛的煞車來令片、離合器時，如果用壓縮空氣吹除粉塵，會導致大量石綿纖維飛散。Automotive Repair: When handling old vehicle brake linings and clutches, using compressed air to blow away dust can disperse a large amount of asbestos fibers.
• 工業與發電廠：維修或更換舊管線、鍋爐的石綿保溫層。Industrial and Power Plants: Repairing or replacing asbestos insulation on old pipelines and boilers.

石綿是一種可以預防的職業病。要保護自己，必須遵循「控制層級」原則，從最根本的方法開始： Asbestos-related diseases are preventable occupational illnesses. To protect yourself, follow the “hierarchy of controls,” starting with the most fundamental methods:

1. 工程控制（最重要）：這是最有效的。例如，在拆除前對材料進行濕式處理（灑水），以抑制粉塵飛揚。同時，將作業區圍封，並使用負壓排氣設備，防止纖維外洩。Engineering Controls (Most Important): This is the most effective approach. For example, use wet methods (spraying water) on materials before removal to suppress dust. Also, enclose the work area and use negative pressure ventilation to prevent fiber escape.
2. 行政管理：制定安全SOP，並對勞工進行深入訓練。特別要強調除污程序，確保工作服上的纖維不會被帶回家，造成家人暴露。Administrative Controls: Establish safe work procedures (SOPs) and provide thorough training for workers. Emphasize decontamination procedures to ensure fibers on work clothes are not taken home, preventing family exposure.
3. 個人防護具（最後一道防線）：這是不可妥協的。
   • 呼吸防護：根據風險等級，佩戴PAPR或N95口罩，並確保口罩與臉部密合。
   • 防護衣：穿戴拋棄式防護衣，工作後在除污區脫下，避免纖維污染便服。
   Personal Protective Equipment (Last Line of Defense): This is non-negotiable.
   • Respiratory Protection: Depending on the risk level, wear a PAPR or N95 mask and ensure a tight fit.
   • Protective Clothing: Wear disposable coveralls and remove them in a decontamination area after work to avoid contaminating personal clothing.
