Confined Space Nvq
P 1.1 - Task 1
Term of Confined space
Confined space is a work environment which is enclosed with limited access which makes it dangerous. It may include storage tanks, tunnels, silos, underground electrical vaults pipelines or vessels.
Confined space hazards
To select the appropriate protective clothing for a specific confined space area or work environment we have to identify the hazards in that particular environment that we want to select it for.
What the hazards can be in confined space? lack of oxygen poisonous gas fire and explosions hazardous liquids left in tanks dust present in high concentrations hot or cold conditions increased water level
What we have to consider when choosing protective clothing and equipment? …show more content…
In the case of electrical equipment, ‘whole current isolation’ such as the main isolator should be used instead of ‘control isolation’ by way of the stop button on a control panel. Any energised equipment to be worked on must be isolated/discharged to ensure the energy is removed or controlled to prevent incidents. This may include ensuring inertia in mechanical parts, parts likely to move by gravity, electrical capacitors, accumulators, springs and pressurized fluids.
Verify that the isolation is effective eg. determine that the equipment is ‘Dead’ ensure any guards are in place and engage the start mechanism of the plant. A qualified worker shall use the appropriate test equipment to test the circuit elements and electrical parts of equipment.
Work must be completed in accordance with the provision of the energy isolation permit. Where electrical isolation is affected at a removable or rack out circuit breaker or combined fuse, switch, if practicable it must be racked out or removed, then locked open and danger tagged.
Lock or otherwise secure all isolating points using padlocks, multi-padlock hasps and danger
