• Dry
• Frost-free
• Decontaminated
• Work must always be carried out by two persons.
• Avoid any painful or tiring body postures.
• When working at a height of more than 1 m (3 ft) above the ground, use scaffolding with a safety harness.
• Cordon off the working area around the scaffolding.
• Toxic or asphyxiating gases may build up when working in closed rooms. Ensure there is sufficient ventilation and observe protective measures according to work regulations (examples):
• Measure the gas concentration before entering.
• Carry a gas detector with you.
• etc.
• Take immediate countermeasures if there is a build-up of toxic or asphyxiating gases.
• To remove/install the cover cap, see “Mounting the cover cap”.
