Typically, welding installation, fastener fixing and angle steel fixing are three methods we commonly used for steel grating installation. Hazard Category Hazards Controls Falls of Materials/ Tools 1. Can occur by hand materials and tools, etc. Being accidentally dropped through the gratings during the grating installation process 1. Per.. 2022. 12. 14. 12. Gas Cutting The process consists of preheating the metal to be cut to its ignition (oxidation) temperature, i.e., above 870°C in case of steel. The preheating is done by oxy- acetylene gas flame, which is supplied from surrounding openings of the cutting torch. When this temperature is attained, a jet of high pressure oxygen from a central opening of the cutting torch is directed on the red hot metal. Hazar.. 2022. 12. 14. 11. Fire Proofing by Spraying Many building codes require fireproofing protection to structural steel as a safety precaution. The most common way to provide such protection is by spraying low-density fiber or cementitious compounds, now called spray-applied fire-resistive material (SFRM). The product can be sprayed on steel to provide heat resistance and also can be applied over wood, fabric, and other building materials. Bu.. 2022. 12. 14. 10. Excavation Work Being a major part of the site preparation, excavation can make or break the stability of your future building. First things first. Do not commence any excavation work before you have a clear map of underground utilities: cables, pipes, etc. Mark the services and make sure everyone in the excavation team knows where the buried services are. Also, test the soil and conduct site evaluation. Armed .. 2022. 12. 13. 09. Electrical Testing It is more likely that this will happen during electrical testing and fault finding, when conductors at dangerous voltages are often exposed. You can minimise this risk if testing is done while the equipment is isolated from any dangerous source of supply, although this is not always possible. Take care to prevent contact with any hazardous internally produced voltages. The most serious injuries.. 2022. 12. 13. 08. Electrical Installation Electrical installations consist as the connection system that has the mission to conduct and distribute the electric current, from the electric service to the last electrical installation outlet, in a edification or construction. Electrical installation describes the physical work involved in installing electrical systems into a building and a plant., etc as testing of electrical wiring and equ.. 2022. 12. 13. 07. Coring on Existing Drainage Sump. Constructing holes in precast concrete manhole sections for pipe connections can be achieved by several methods. Each requires careful consideration before making the investment in training and equipment. Whether you are building a new plant and trying to decide which production method to use or you have an existing plant and want to determine if your current method is the most efficient, it’s i.. 2022. 12. 13. 이전 1 ··· 4 5 6 7 8 다음 728x90
