Safety¶
Water treatment hardware mixes electricity, pressure, biological exposure, and sometimes UV or chemicals. Treat safety as design work, not a footnote.
Core Hazards¶
| Hazard | Typical source | Control approach |
|---|---|---|
| Electrical shock | wet connectors, damaged insulation, poor grounding | sealed connectors, strain relief, isolation, inspections |
| Pressure release | clogged filters, dead-headed pumps, trapped air | relief paths, gauges, shutdown logic |
| Biological exposure | raw water handling, sludge removal, contaminated surfaces | gloves, containment, cleaning procedures |
| UV exposure | open or damaged UV chamber | shielding, interlocks, service lockout |
| Chemical mishandling | disinfectants or cleaning agents | labeling, PPE, storage discipline |
Operator Rules¶
- isolate power before opening electrical enclosures
- depressurize wet-side modules before service
- treat sludge and dirty consumables as contaminated waste
- document any bypass or safety override used during testing
Shop and Field Readiness¶
Before running a machine outside the bench:
- verify emergency shutdown behavior
- check that all drains route away from electrical equipment
- confirm that service tools and PPE are physically nearby
- make sure the operator can identify clean-side versus dirty-side components quickly
