The petroleum industry both mining and crude oil processing has a high level of fire risk. This can be caused by the hydrocarbons from the content of mining products, crude oil content to the fuel which is contained in the area around processing. Where, if there is a fire in the surround area can cause a terrible explosion in the oil tank or pool fire. To identify the potential fires, a manual assessment method can be carried out by: making clusters and grouping of production activities, risk matrix table of industrial activities, field observations, identification of hazard materials, analyzes and actions in accordance with the standard operating procedures applied in the company. From the results of observations on the oil and gas industry in Sumatra – Operation Indonesia, generally the identification of potential fires is good, there are several factors that must be taken so the zero accidents in the oil industry can be fully satisfied.
In densely populated settlements, fires often occur and cause losses. In some instances, the process of the occurrence of fires takes place so quickly that to reduce and avoid the occurrence of a fire disaster effort is required in accordance with the existing environmental condition. Fire fighter motorcycle by using motorcycle scooter-matic is considered suitable as one alternative to combating fire hazard in densely populated residential settlements. The use of motorcycle engines as the driving force of the pump often leads to unstable and not optimum power. Thus, the water spray on the centrifugal pump also becomes not maximum. To increase the engine power at scooter-matic engine idle rotation (700-2000 rpm), then the flying roller replacement with certain mass weight becomes an option. By selecting a 10 to 14 gram flying roller mass, the power analysis using a dynotest engine produces several variations. Of the calculation, the mass of a 14 gram flying roller provides a significant increase in motor power on the upper rotation. Meanwhile, on the lower power rotation using a flying roller with a mass of 10 grams provides an increase in power compared to a standard flying roller on a scooter matic motor engine. As a reference to the use of scooter-matic motor power as the pump power, the result of use of the flying roller with a mass of 10 grams becomes the best option.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
