1.7 APPLICATION EQUIPMENT
1. Equipment mobile machinery
Mobile machinery including delivery trucks, tank truck crane, hoists etc ...
Only allow the mobile equipment has passed inspection skilled worker control on construction sites.
At-risk place mobile machinery can come into contact with electricity, all electrical wires must be fenced or signal flags. These wires are at risk of causing accidents must be a power interruption, or make safe before starting any work went public.
Not to have machinery that operates on electrical wires.
Never operate machinery lies mains voltage> 220 Volt a less than 4.5m. Just being there is only one nominee for the prime performance machine operator, except emergency stop signaling.
Avoid traveling near or just below 1 len.Tat both objects being crane hoisting loads are wired up to soups (tag line) to drive things.
Before hoisting anything, must clearly identify the standing position of the crane and the crane down of positions in the construction area. The work must be carried out to ensure occupational safety and risk analysis can be (based on the Health and Safety in the installation process at the site).
Before hoisting plants, cranes should be positioned and the crane folded hands to push the water out. Arm length, angle required, radius of hot and safe lifting load must be estimated based on the schema Hoisting manufacturers.
In every stage of construction, probably to avoid or minimize the damage portion of the material of paint finishing, using wire or belt nylon cape with protective buffers in places exposed to the metal structures ; or by using a regular pierced holes Boulon shackles to lift.
2. Wire cranes and slings required:
Should definitely check carefully the crane and sling cables required. The cables and wires hanging damaged must be removed and destroyed immediately.
When conducting cranes, crane avoid arbitrary strings. Need protected by wire cranes lining the seat angles. Absolutely no sudden shock when the crane, because the sudden shock loads will increase 3 times normal, dangerous for hoisting rope. When not in use, it should be neat trough crane wire. Never let wire crane overload.
3. Seamless Education Execution
Must use planning as well as construction scaffolding installed so as not to obstruct the movement of the crane arm and about themselves, nor make it difficult for construction operations.
Always scaffolding Statistics on hard ground or right seat plank, minimum size 200 x 200 mm. The scaffolding had been arrested separately Statistics tight security on fixed structures with a minimum of 1.5 m of space. Each floor scaffolding to hold above the floor under the wire or pipe scaffolding, so that to ensure safety.
4. Hand tools:
All hand tools must have a strap that held against falling
To use the device for the right purpose. Never use a portable device for jobs outside the intended purpose. Never use the temporary replacement equipment.
Certainly never use the tool was broken, machinery and equipment which windings frayed or erroneous or without shooting guard.
Must shutdown and isolated from the power source, and special warnings when carrying out cleaning and adjustment.
Have guessed that the machines will not operate before removing the protective shutter for repairs or adjustments.
To report on all the machines damaged paint, breakage ... for the captain.
5. Cutting with welding flame:
Only skilled workers, are adequately trained and have the new guidelines are allowed to use the oxygen equipment, gas, welding equipment. Monitoring Health and Safety Project required to conduct initial inspection and save the report before allowing use.
All scuba browser must be stamped and approved for use. The compressed gas cylinders should be porters careful, avoid collisions, bumped or dropped. Must always preserve this bottle in an upright position.
The compressed gas cylinders should be moved by trolley, not rolling. When hoisting cages or crates used to hold, never use a lifting magnet.
On pneumatic cylinders have safety cap when not in use and when being transported.
There should be safeguards against fire backwards by the instruments already adopted, to avoid the fire from spreading to the system of gas cylinders.
Wind is not rock torch water hammer to knock slag used as welding or soldering flakes.
Before conducting burning, welding or heating, workers are responsible for checking the other side or the bottom of the object to be sure that all danger from fire or damage have been excluded. Fire extinguisher must be available properly.
Never been heating an object lying flat on the concrete floor. Should ensure that there is an air gap between the material and the concrete if the concrete will not crack if the temperature is too high.
Not to torch the wind kicks in a closed jar or container. Leaks can be the beginning of a disastrous explosion.
Before leaving the workplace, to turn off gas valve on the tube by the lead and followed by van on the torch. Need guess no gas leaks.
Conduct regular inspection of the entire field of welding, air ducts, air pressure meter and other combustion devices,
