设备进水、断路器跳闸和怀疑触电，都是必须停下来的情况。
- 手册、标签、当地规范和现场条件都优先于 Poolometer。
- 在电气路径明确安全之前，保持泳池关闭。
- 湿壳体、等电位连接或带电测试交给合格电工。
Drain Cover Safety Zones
Main drain covers are safety-critical. Removing them exposes suction entrapment hazard. Only qualified service should touch drain assemblies.
Visually check covers for cracks, missing screws, or loose fastening. If the cover moves or is damaged, stop pool use and call service.
Covers must meet ASME/ANSI anti-entrapment standards. Ensure multiple drain or safety vacuum release system is in place (VGB 2008 compliance).
Heater Safety Zones
Minimum 6 inches of clearance on all sides. Do not store anything against the heater cabinet.
Do not store pool chemicals, solvents, or flammable materials near the heater. Corrosive vapors damage internal components.
Never operate the heater without water flow. Dry-firing or running with air in the heat exchanger causes rapid failure and fire risk.
Lighting, Electrical, and GFCI Safety
Treat pool lights, receptacles, pumps, and breakers as water-adjacent life-safety equipment, not casual DIY territory.

- Breaker panel access and labels
- GFCI test button accessibility
- Emergency shutoff path known to household
- Do not enter the water if electrical shock is suspected
- Do not open wet electrical enclosures or improvise repairs around water
- Do not use extension cords near the pool edge
Know the pool-light, pump, and subpanel breaker locations. Label them clearly. Seconds matter in an electrical emergency.

Breaker panel access and labels / GFCI test button accessibility / Emergency shutoff path known to household
Know the emergency shutoff path
In an electrical emergency, seconds matter more than diagnosis.
Use GFCI protection and professional inspection
Older pools and aging lights are special concern areas.
Respect owner-safe boundaries
There is a difference between identifying a hazard and repairing it.

电气工作的边界
泳池电气工作直接关系到生命安全。除非任务明确属于业主可安全执行的范围，否则只做观察。
- ✓ 标记断路器，测试 GFCI 装置，并记录可见的腐蚀、松动的盖板或进水。
- ✓ 如果能安全操作，就从干燥且容易接近的断路器位置切断电源。
- ✓ 让所有人远离水体，并为合格的泳池电工保留现场。
- ★ 打开配电柜、修理照明回路、更换市电泳池灯，或纠正等电位和接地缺陷。
- ★ 排查潮湿外壳、损坏的线管、腐蚀端子或设备内反复跳闸的断路器。
- ★ 只有在你具备资格并配备相应工具时，才可在泳池设备周围进行带电测试。
- ⚠ 有人在水中或金属设备上感到触电。
- ⚠ 断路器反复跳闸，线路烧焦，或壳体内部潮湿。
- ⚠ 灯槽、水下灯具或相邻回路看起来已受损。
