合計 100% 四. 急救措施： 不同暴露途徑之急救方法： 吸入 ：1.立即將患者移致新鮮空氣處。2.若呼吸停止施予人 工呼吸，若心跳停止，則施予心肺復甦術。 3.立即就醫。 皮膚接觸：1.立即用溫水緩和沖洗10分鐘以上。 2.在沖水中脫掉污染衣物，鞋子及皮飾品﹝如：錶帶、皮帶﹞。 3.若有刺激感反覆沖洗。 眼睛接觸：1.立即將眼皮撐開，用緩和的溫水沖洗。 2.勿讓沖洗過的污水污染其他不位。 3.立即就醫。 食入 ：1.若患已喪失意識或痙攣，勿餵食。 2.用水徹底清洗口腔，勿催吐。3.給患者喝240~300ML水以稀釋胃 中物質。4.若患者自發性嘔吐，令其漱口並反覆給水。5.立即就醫。 最重要症狀：會抑制神經系統、頭痛、嘔心，甚至失去意識。 對急救人員之防護：戴防護手套，以避免接觸污染物。 對醫師之提示：患者吞食時，考慮洗胃及通便。 五、滅火措施 適用滅火劑： 二氧化碳，化學乾粉，乾砂泡沫材料。 滅火時可能遭遇之特殊危害： 1.易燃，室溫下易引燃。2.蒸氣比空氣重，會傳播致遠處，遇火源可能造成回火。3.火場中可能 釋出毒性氣體。4.可能蓄積於密閉空間，造成毒性及易燃性的危害。5.濃的水溶液亦可燃。6.密閉容器加 熱可能劇烈爆炸。 特殊滅火程序： 1. 將容器運離火場並於上風處滅火。2.在不為及人員安全下，先止漏，因其蒸氣可與空氣混合而在引燃。 3.若無法止漏且周圍空曠，責任火燒盡。4.不宜用水霧滅火，但可噴水霧以冷卻暴露於火焰之容器外側 ，並驅散或稀釋其蒸氣。5.物料儲存區發生大火，應使用無人控制之水帶控制架或自動搖擺消防水瞄以 水灌救。 消防人員之特殊防護設備： 消防人員必須配戴空氣呼吸器，消防衣及防護手套。 六、洩漏處理方法 個人應注意事項： 1. 限制人員進入，直至外溢區完全清乾淨為止。 2. 確定是由受過訓之人員負責清理工作。 3. 穿戴適當個人防護裝備。 環境注意事項： 1.對該區進行通風換氣。 2.撲滅或除去所有發火源。 3.報告政府安全衛生與環保相關單位。 清理方法： 1.不要碰觸外洩物。2.避免外洩物流入下水道或其他密閉空間。3.在安全許可狀況下設法阻止或減少溢漏。 4.用砂，泥土或其他不予洩漏物質反應之吸收物質來圍堵著洩漏物。5.少量溢漏時，用不會和外洩物反應之 吸收劑吸收。已污染的吸收劑和外洩物具有同樣危害性，須置於加蓋並標示的適當的容器裡。用水沖洗溢漏 區域。6.大量溢漏時，連絡消防，緊急處理單位及供應商以尋求協助。 七、安全處置與儲存方法 處置： 1. 此物質是易燃性液體，處置時工程控制應運轉及善用個人防護設備；工作人員應受適當有關物質之危 險性及安全使用法之訓練。 2.除去所有發火源並遠離熱及不相容物。 3.工作區應有"禁止抽煙"標誌。 4.液體會累積電荷，考慮額外之設計以增加電導性。如所有桶槽、轉裝容器和管線都要接地，接地時必須接觸到 裸金屬，輸送操作中，應降低流速，增加液體留在管線中之時間或低溫操作。 5.當調配之操作不是在密閉系統進行時，確保調配的容器和接收的輸送設備和容器要等電位連接。 6.空的桶槽、容器和管線可能仍具危害性的殘留物，未清理前不得從事任何焊接、切割、鑽孔或其他熱的工作進行。 7.桶槽或儲存容器可填充惰性氣體以減少火災和爆炸的危險。 8.作業場所使用不產生火花的通風系統，設備應為防暴型。 9.保持走道和出口暢通無阻。 10.儲存區和大量操作的區域，考慮安裝溢漏和火災偵測系統及適當的自動消防系統或足夠的緊急處理裝備。 11.作業避免產生霧滴或蒸氣，在通風良好的指定區內操作並採最小使用量，操作區與儲存區分開。 12.必要時穿戴適當的個人防護設備以避免與此化學品或受污染的設備接觸。 13.不要與相容物一起使用﹝如強氧化劑﹞以免增加火災和爆炸的危險。 14.使用相容物質製成的儲存容器，分裝時小心不要噴灑出來。 15.不要以空氣或惰性氣體將液體自容器中加壓而輸送出來。 16.除非調配區以耐火結構隔離，否則不要在儲存區進行調配工作。 17.使用經認可的易燃性液體儲存容器和調配設備。 18.不要將受污染的液體倒回原儲存容器。 19.容器要標示，不使用時保持緊密並避免受損。 20.儲存在陰涼、乾燥、通風良好以及陽光無法直接照射的地方，遠離熱源，發火源及不相容物。 21.儲存設備以耐火材料構築。 22.地板應以不滲透性材料構築以免自地板吸收。 23.門口設斜坡或門檻或挖溝槽使洩漏物可排放至安全的地方 儲存： 1.儲區應標示清楚，無障礙物並允許指定或受過訓人員進入。2.儲存區與工作區應分開；遠離升降機，房間出口或 主要通道儲存。3.儲存區附近應有適當的滅火劑和清理溢漏設備。4.定期檢查儲存容器是否破損或溢漏。5.檢查所 有新進容器是否適當標示並無破損。6.限量儲存。7.以相容物質製成的儲存容器裝溢漏物。8.儲桶接地與其他設備 等電位連接。 9.儲存易燃液體的所有桶子應安裝釋放壓閥和真空釋放閥。10.依化學品製造商或供應商所建議之儲存溫度儲存， 必要時可安裝偵溫警報器，以竟是溫度是否過高或過低。11.避免大量儲存於室內，盡可能儲存於隔離的防火建築。 12.儲槽之排氣管應加裝火焰防止裝置。13.儲槽須為地面儲槽，底部整個區域應封住以防滲漏，周圍須有能圍堵整 個容量之防溢堤。 八、暴露預防措施 工程控制：局部排氣裝置或整體換氣裝置。 控制參數：八小時日時量平均容許濃度/短時間時量平均容許濃度/最高容許濃度： 100mg/m3 個人防護設備： 呼吸防護：600PPm以下：供氣式呼吸防護具 不知濃度：正壓全面型供氣式呼吸防護具輔以正壓自攜式呼吸防護具。 手部防護：防滲手套，材質建議以丁基橡膠，Tefion、4H、Barricale、Chemrel 眼睛防護：1.護目鏡﹝最小8英吋﹞。2.防濺安全護目鏡。3.勿戴隱形眼鏡。 皮膚及身體防護：化學防護衣。 衛生措施： 1.工作後儘速脫掉污染之物，洗淨後才可再穿戴或丟棄且須告知洗衣人員污染物之無害性。 2.工作場所嚴禁抽煙或飲食。3.處理此物後，需徹底洗手。4.維持作業場所清潔 九、物理及化學性質 物質狀態：粘稠膏狀液體 形狀：膏狀液體 顏色： 黑 氣味：芳香味 pH值：可能為微酸性 沸點/熔點範圍： 分解溫度：未測量 閃火點： 測試方法： 開杯 閉杯 自燃溫度：
