Materials commonly used for tank design include carbon steel, stainless steel, and aluminum.

• Carbon steel is often used for its strength and affordability

• Stainless steel is preferred for its corrosion resistance

• Aluminum is lightweight and resistant to corrosion

• Fiberglass reinforced plastic (FRP) is also used for its corrosion resistance and durability

The minimum distance allowed for mechanical excavation near underground electrical cable is dependent on the voltage of the cable.

• The minimum distance should be determined by a competent person

• The voltage of the cable should be identified

• The distance should be at least equal to the depth of the cable plus 500mm

• If the voltage of the cable is higher, the distance should be greater

• The excavation should be carried out carefully to avoid damaging the cable

The required minimum height to use safety harness is 6 feet or higher.

• The minimum height requirement for safety harness varies depending on the industry and jurisdiction.

• In general, the minimum height requirement is 6 feet or higher.

• This is to ensure that workers are protected from falls and other hazards.

• Employers should always follow the guidelines set by their industry and jurisdiction to ensure worker safety.
