ETHICS SAFETY AND SAFETY worry - Essay ExampleThe powder is collected in a receiving vessel (hopper) from where it can be employ in a further stage of the process. The receiving vessel is fitted with a filter to allow the air use in the pneumatic transport process to be separated from the powder which collects in the receiving vessel. This pneumatic conveying system differs from a normal pneumatic conveying system in that the receiving vessel is placed to a higher place the blow tank system. A pipeline is used to transfer the pharmaceutical powder, Pharmex from the blow tank to recipient vessel to some distant sphere. A filter is used at the receiver tank and lastly the powder settles down. The air compressor feeds the system with air under a desired pressure. In figure 1, the rest valves and the regulator valves ar shown as PRF and NB respectively. Introduction Risk assessments are conducted in order to order any get up & explosion hazards before the commencement of a proc ess. Control of Substances Hazardous to Health (COSHH) (Health and golosh Executive, 2003) regulations is a useful tool for this work. It is imperative that employees be prevented from exposure to hazards. Implementation of COSHH regulations leads to i. Higher productivity and expertness by the use of more effective controls. ii. Improved employee morale. In this exercise, we will try to find bulge out where there is enough powder present in this process for explosion to occur. Powder more than 80 gm/m3 is quite enough to wipe out an explosion. The plant has powder transported from one area to another area by blowing it, which means the pipeline has the mixture of powder and air and thus possesses the potential of explosion. Explosive Atmospheres In pneumatic conveying system, workplace air and Pharmex can form the explosive atmospheres and this condition can be classified as hazardous area according to DSEAR (DSEAR 2002, SI 2002/2776). Therefore special precautions over excita tion and fuel sources are required to prevent fire and explosions. Non hazardous area outside the workplace involve risk assessment as well. Hazardous areas are further classified as Zones which are include in DSEAR. When we talk about dangerous substance and explosive atmosphere regulations then we look at Zone. Zones Pharmex and air form a mixture in the process. Pharmex is susceptible to explosion. The mix of air and Pharmex is present interminably in the pneumatic conveyer system. Therefore, the apparatus is considered as Zone 20, according to DSEAR. To start the process we have to put the powder into the plant, as the powder is not present continuously, hence the filling of powder is in Zone 21 according to DSEAR. The proposed equipment for zone 20 is category 1 equipment, following DSEAR regulations. Risk sound judgement First, the hazards that have potential to cause harm are identified. Secondly, the risks present to peoples health are assessed. Regarding the conveying sy stem shown in figure 1, the main hazards are fire and explosion. Fire & Explosion Figure.2 The supra triangle illustrates that igniting and burning a fire or causing an explosion requires three elements mentioned at the rim of the triangle. 1) Ignition source The ignition source can be directly associated to heat. 2) Fuel Is necessary for the fire or explosion to burn. 3) Oxidiser Substances also necessary for the reaction of fire or explosion. Oxygen is the most(prenominal) common oxidiser. The fuel (Pharmex) and oxidation (air) are present at most places in the
