🏠⚠️ 9 HIDDEN HAZARDS INSIDE YOUR HOME HOW SAFE IS YOUR HOME 🦺 A home should be the safest place for you and your family but everyday activities can hide serious hazards. 🔍 Many incidents don’t happen because of a major mistake. They happen because of a small hazard that was noticed but ignored. A loose cable, wet floor, overloaded socket, chemical bottle left within reach, or blocked exit can quickly become an accident. 🚨 Here are 9 common home hazards everyone should check today: 🔌 1️⃣ OVERLOADED OUTLETS Too many appliances connected to one outlet or power strip can cause overheating, electrical faults and fire. ✅ Avoid overloading sockets and power strips. ✅ Use properly rated electrical equipment. ✅ Inspect plugs and cables for damage. ✅ Avoid unsafe daisy-chaining of extension cords. 🍳 2️⃣ UNATTENDED COOKING Cooking equipment should never be left unattended, especially when using oil or high heat. ✅ Stay in the kitchen while cooking. ✅ Keep towels, curtains and other c...
Allowable
TSS in Chilled Water Closed Loop
A professional
explanation of the allowable
Total Suspended Solids (TSS) in a chilled water closed‑loop system, written in an engineering tone
suitable for technical documentation or maintenance standards:
💧 Allowable TSS in
Chilled Water Closed Loop
🔹 Definition
Total Suspended Solids (TSS) represent fine
particulate matter—such as rust, scale, silt, or biological debris—suspended in
the chilled water circuit. High TSS levels can cause erosion, fouling, and
reduced heat‑transfer efficiency in chillers, coils, and pumps.
🔹 Recommended Limits
|
Parameter |
Recommended Value |
Remarks |
|
TSS (Total Suspended Solids) |
≤ 10 mg/L (ideal) |
For clean, well‑maintained closed loops |
|
Acceptable Range |
10–25 mg/L |
Requires filtration and periodic flushing |
|
Critical Limit |
> 25 mg/L |
Risk of fouling, corrosion, and pump seal wear |
These values align with ASHRAE Guideline 12, BS RIA 2000,
and HVAC water treatment best practices.
🔹 Control Measures
- Side‑stream
filtration: 5–10 micron filters to continuously remove particulates.
- Chemical
treatment: Corrosion inhibitors and dispersants to prevent deposition.
- Periodic
sampling: Monthly analysis for TSS, conductivity, and pH.
- Flushing
and cleaning: During commissioning and annual maintenance.
- Magnetic
filters: For systems with steel piping to capture ferrous particles.
🔹 Impact of High TSS
- Reduced
heat‑transfer efficiency in coils and heat exchangers.
- Accelerated
corrosion and erosion of pump impellers and valves.
- Increased
maintenance frequency and chemical consumption.
- Potential
sensors malfunction due to particulate deposition.
✅ Conclusion
Maintaining TSS below 10 mg/L ensures optimal
performance, energy efficiency, and long‑term reliability of the chilled water
closed‑loop system. Regular monitoring and filtration are essential to sustain system
cleanliness and operational integrity.
