Regulations for Safety Inspection of Hazardous Machines and Equipment Article 133
If the internal inspection for the special equipment for high-pressure gases shown below cannot be carried out, the employer shall submit documents including safety and health management status, auto inspection plans and implementation records, photocopy of the qualification specification for the structure inspection of the vessel, detailed structure drawing, production flow chart, emergent treatment plans, auto control system and proposal of substitutes at the inspecting organization for approval of extending the period of the internal inspection or substitution with other means of inspection:1. Those free of manholes or cannot be equipped with manholes, leaning holes or inspection hole due to structural reasons.2. Cold boxes, flat low-temperature tanks, oxygen tanks, liquid nitrogen tanks, liquid argon tanks, low-temperature evaporators and other low-temperature or ultra-low-temperature equipment for high-pressure gases.3. Those with accelerant, molecular sieve or other special contents inside.4. System equipment that cannot be separated during the continuous production procedure.5. Diaphragm type tanks or non-corrosive equipment.6. Others that have difficulty in internal inspection.If the special equipment for high-pressure gases mentioned in the previous paragraph are attached to Category Ι pressure vessels or boilers, the inspection period shall be extended accordingly.

雇主對於下列高壓氣體特定設備無法依規定期限實施內部檢查時，得於內部檢查有效期限屆滿前三個月，檢附其安全衛生管理狀況、自動檢查計畫暨執行紀錄、該設備之構造檢查合格明細表影本、構造詳圖、生產流程圖，緊急應變處置計畫、自動控制系統及檢查替代方式建議等資料，報經檢查機構核定後，延長其內部檢查期限或以其他檢查方式替代：
一、依規定免設人孔或構造上無法設置人孔、掃除孔或檢查孔者。
二、冷箱、平底低溫儲槽、液氧儲槽、液氮儲槽、液氬儲槽、低溫蒸發器及其他低溫或超低溫之高壓氣體特定設備。
三、內存觸媒、分子篩或其他特殊內容物者。
四、連續生產製程中無法分隔之系統設備者。
五、隔膜式儲槽或無腐蝕之虞者。
六、其他實施內部檢查困難者。
前項高壓氣體特定設備有附屬鍋爐或第一種壓力容器時，其檢查期限得隨同延長之。
