1.3 Installation :
•
Excavation work should be planned with due regard to health and safety requirements.
•
Excavation should either be shored or battered back to a “safe” angle.
•
Use appropriate lifting equipment
•
Care should be taken around grounds work machinery
•
Keep proper footing and balance at all time
2. Transportation, unloading and storage of tanks
:
1. Tanks must be held down during transportation using nylon straps, do not use cables or chains to
secure tanks. Do not over tighten straps to cause deformation of the tank shell. Do not drop or roll tanks from
the truck.
2. Move tanks only by lifting and setting, do not drag or roll.
3. Always set the tank(s) on flat smooth ground free from debris etc. To prevent movement, tanks may need to
be tied down and chocked.
4. Tanks are best lifted by a machine and webbing lifting straps – do not use chains or wire ropes in contact
with the tank. Ensure tank is empty when lifting. Care is needed to control the lift to ensure the tank is not
damaged.
5. Tanks from one to four modules (4.6m) in length should be lifted using the eyebolts on the tank.
To ensure the angle of the sling is not greater than 60
o
, as per option 1, the following sling lengths are
required:
