Study Notes
Safety Measures in Cable Trenches
- Concrete cable trenches are filled with sand to prevent the accumulation of hazardous gases.
- RCC (Reinforced Cement Concrete) covers of trenches in process areas are sealed to prevent the ingress of chemicals and oil.
Cable Joints and Fire Safety
- Non-fire-retardant cables with straight through cable joints on cable trays must be painted with fire retardant paint.
- Straight through cable joints inside cable cellars should be avoided, but if unavoidable, they must be painted with fire retardant paint.
