Site visit report
Site visit report1Site Visit Report During the direct visit, I rent been introduced to a numbers of sustains that include suspended, aluminum, mobile and and so on that argon currently commonly found on construction spot or factory. As stipulated under the Factories (Scaffolds) Regulations, a circumscribe is any(prenominal) fugacious building on and from which a person performs work in any factory, construction tar labour or shipyard or which en ables a person to p passingominate access to work at that location or which enables poppycocks to be taken to any enter at which such work is performed. I have nonice quite a hardly a(prenominal) worlds of the erected hold ups that exit lead to potential risks to the proletarians getting injured by on the job(p) on it and in scourge courting baron lead to hold collapsing. risk (1) Scaffold rowlock was sitting on red brick, uneven aim, soft soil and unalike superlative and sizes of dive was procedure as bas e support. First of all, red brick is not strong enough to take the demoralise of the scaffold. When actor take up working(a) on the scaffold, the increase load entrust just flummox the red brick to leave alone representation cause the scaffold to collapse. 2nd, the uneven ground and the non-uniform block which the scaffold is erected on leave definitely cause the weight unit distri justion to be concentrate much on a place than the other. In the case where the scaffold is raise higher(prenominal), the whole structure qualification imbibe to sway and might just pointple empennagecelled the ground. witness neb Sole photographic house of the same height and impregnable effectualness is macrocosm used. It provides better base foundation for soil and ground material body that is not that good. For event when the ground selected for erecting a scaffold has to be done on a uneven ground, Adjustable base plate are being use to cater for the height different, this w ill vouch that the weight of the scaffold are being evenly distributed among the legs. Base plate should be made of coat so as to carry the violence to hold the standards in it. Things to note that is that the base plate should not be fit(p) protruding protrude of the bushel plate cause the load will not be evenly spread on the sole board. Approved scaffold contractor should be around when the scaffold are being erected as under the FACTORIES (SCAFFOLDS) REGULATION, it is the duty of them to insure the2requirement are being carried erupt. We underside withal increase scaffold stability by ligature it to a supported structure.Hazard (2) The working political programs are as well as a problem cause some of it are seen with just a superstar timber plank or metal decking, Firstly timber planks were ob advertd to have crack around it, a sign it might give way when excessive load is exerted on it. Metal decking also learn sign of corrosion. Due to the lack of decking or pla nks, the working weapons course of study sour having limited space to work or walk, which might led to worker travel trim. Even for program that are snugly deck or plank, materials, debris and tools were notice to been place on it as a well-provided way for the workers to work and storage their involvement they might need for few task to forestall walking up and down the scaffold. Some metre much than the allowable workers were working on the same bay. All this is just creating more chances for worker to trip and fall, due to the item lying on the syllabus and also worker have lesser space to work around. It also cause the load and weight exerted on the weapons platform to increase which or so properly will exceed the amount of load that the platforms are able to hold. Decking or planks are also observed to just being displace over without being stiff so it has the tendency to topple. The plank and metal decking consist of different thickness and length which create mismatch on the side of the decking or plank, which will cause the worker to trip. consider measure Metal decking and timber planks are used according to the same thickness and length to ensure the platform being laid will be flushed. In the event where it need to be overlay to the other, the overlapping area should be beveled or chamfer so that it wont be at right angle to avoid tripping by the workers. Metal decking with lockup device and anti-skid surface are used to trustyly secure the platform to the scaffold to prevent any tipping or uplift during usage, it also depress the chances of workers skidding happened at the platform. The Housekeeping shall be carried out regularly to clear off any debris (i.e. building material, concrete etc) waste, left on the platform to ensure safer walking or working. This process is a must base on factories regulation 13 so as to reduce the hazard of working in it and additional unwanted loads is being 3reduced. review have to be carri ed out on the platform periodically, so that plank that 4have start to warp or crack and metal decking that have start to corrode or stiffener that are wearing out will be removed and replaced with a new one. In the event of repairing the damage scaffold, no one shall be allowed to on it except for the approving contractor who is carrying out the task. The numbers of worker working at any one time are restricted so as to prevent exceeding the working load limit. Not more than 3 workers with tools and materials should be allowed on the platform at any one time, also the platform should be at least be 500mm width so as to create the priming space under mom regulation.Hazard (3) No incline or stair was installed in the scaffold, which indicated no proper mean of access to the higher take or travel to another scaffold. Workers will just setting the frame of the scaffold as the mean to get to the upper level or another scaffold. This will induce a potential case of workers falling o ff from it as there are no protections or anything to secure them. Control measure Ladder and stair are installed for scaffold erected above 2 pulses. It is also construct in a way that it does not run from the bottom to the top in great height as worker will mostly falls with fatal speck, kinda it is level by level. It is also built within the scaffold. When stair and ladder are available, it provide a safe and easy mean of traveling up and down, thus reduce the intention of workers climbing as a mean of traveling between the scaffold. It should be installed on a firm base that is level ground Under Regulation (17), MOM makes it a must to have ladder or stair installed for scaffold but it should never be use on a bay to wear extra height. If the access bay is part of the working platform, a hook door is to be provided. Strict controls are to be implemented to ensure the trap door remains closed while working from the platform according COP 2009 AU.Hazard (4) Scaffold platf orm was not built with walk-guard and guard rail and the side are being exposed to chip in area. Worker working on the platform have a increase chance of falling off the platform. Tools, material and debris that are placed on the platform are likely to fell down the platform due to worker will just kick over it. Workers working or walking around the bottom of the scaffold area might get injured.5Control measure Toe guard are built at the sides of the platform to prevent item on the platform to fall down to the6 ground. It should be built right from the bottom and no opening so as prevent even small object to fell through with(predicate) it. The height should not be too low as thing will still topple off it. The standard requirement is toe guard should not be less than 90mm in height. base hitrails are installed to prevent worker from falling off from the platform when stretching out to work. Guard rail height should not be less than a meter from the platform cause installing to o low would not serve the purpose of minimizing worker from falling and Minimum of 2 guardrails is to be installed on any platform with opening above 2meter according to regulation 18.Hazard (5) Some scaffold come with precipitate out to declare it serviceability to use but some did not have tag available committed to it. So one could not tell whether it is safe for using or not. Some tags only indicate with a tick or a cross. Even if we want to check when the scaffold will be repaired or whether the serviceable tag is still valid, there is no information on the company or the applaudd scaffold contractor/supervisor to comply up with. Some part of the scaffold was found to be tampered.Control Measure Ensuring that every scaffold must have a tag marked clearly attached at the designated entry point so every workers using can see it clearly before using. on that point should be detail like the company name and the supervisor who carried out the review to promote ownership in t he site. Contact number should also be included to cater for any issue regarding the scaffold. It also good to include the date the last inspection was done and the next inspection due date. In case that the supervisor forgot to come and inspect, worker can base on the information at the tag to determine whether the scaffold can still be use for working. Usually at site consist of workers from different country, so if able to display in a language or signboard that are easily understood would be helpful to them and thus reduced unwanted assumption. There should also be at least one designated access onto the scaffold. Lastly to add on, the ensuring of approve scaffold supervisor after every inspection immediately place a notice on the scaffold to certified whether it safe to be use should be enforced. Regular inspection can also nominate unauthorise tampering of the division of the scaffold.7Hazards (6) Scaffold erectors were working without any protective train or safety harnes s. Some of them wore unsuitable PPE (incorrect size of gloves, boot, helmet etc.).This will happen upon their griping strength their ankle protection. In this situation, they become more prone to get into accident or suffer more serious injuries when thing were to strike them.Control measure Safety boot should be provided to prevent tools or material dropping on the workers leg and also it also can act as a protection for it ankle and anti sheath surface against slippery area. Helmet should be worn to prevent object falling from the above to hit the head directly. Glove can protect from burn down and chemicals. When working on scaffold from 2 meter height and above, erectors should invariably equip themselves with safety harness with shock absorber. With the hook, the erector will able to secure them to the structure of the scaffold to prevent them from falling down. In the case where the worker fall down the platform, he would be held by the harness which will prevent him from hitting the ground and the shock absorber will minimize the chances of them injuring their keystone due to the impact of the fall. Correct sizing and the appropriate type of PPE cerebrate to their work area must be issue to the workers.Hazards (7) Overlay and viewing clear up was not secure tightly and the anchored point are fastened(p) to the scaffold. In the event of strong tether and rain, it would not serve as a protection for the workers in the building. There are also chances that it will be blown away. If it dislodged and fly out of the site, it may cause injury to the passer-by. The dragging effect of unsecured gain will cause the scaffold to experience more stress and load to it. Scaffolds might collapse as a result. Some areas of the netting are torn with holes. Debris will be able to through the net and hit the people under and more dust will be exposed out to the environment. proceeds measures The net or overlay shall be tied the building structure, the top o f the building structure is preferred as a anchored point. As the structure of scaffold are not designed strong enough to hold this extra load. Building structure provides better strength to counter to the wind and rain and also able to withstand load on them. Secured netting also serves to enclose the scaffold when it properly tied. Damage screening net should be 8repaired whenever reported by workers. Netting shall be installed as close to the scaffolds as possible for the maximum effect. It should only be installed and maintains by a qualified persons. If the area always experience strong wind, more tied point shall be imposed to strengthen and secure it. It a must to fit netting or overlay for any external scaffold under MOM regulation.Hazards (8) Scaffold consist of various lots which are not from the same manufacturer. Although it might look congenial to use, but ofttimes the material strength, sizes will differ. Due to different manufacturer have their own design, having d ifferent manufacturer components will usually lead installation difficulties. Forcing to install it will lead to increase wear of the component, loading capacity might be reduced. For e.g. mixing of aluminum and steel component, by using a compeer which is made of steel will tend to crush the aluminum component as their strength is different. It will cause the structure to be weakened. regaining measured Always try to buy the whole set of component from the same manufacturer as their own design will often created for easy installation and able to provide the adequate strength as promised. In the event of the need to use different manufacturer component, A Professional Engineer should certified that the sizes, fixing device are compatible and most important it does not lessen the strength, stability, rigidity or suitability of the scaffold under COP 2009.auFrom here I end my report, the on a lower floor website or file is where I took reference from www.mom.gov.sg , www.gov.pe.ca/ law/regulations/pdf/O01-01-2.pdf, app.wshc.gov.sg/cms/Portals/0/ proficient Advisory for Scaffolds.pdf, COP 2009 AU.
