T0020 Conducting the First-ever Fire Assessing Risk Assessment of Fires at Gasoline Stations
If you have ever been in a When you stop at a petrol station to refuel your car, you would have seenhave you noticed posters prohibiting the use of mobile phones and cigarettes?. This isThis prohibition is because sparks from mobile devices and , cigarette smoke, etc can combine with oxygen and fuel vapors in the air, leading to a risk of to cause fires. Gas stations are filled with all sorts of noxious vapors, such as benzene, which has been shown tonot only have a negative ly impact station on workers’ health but also increase the risk of fire hazards. With serious consequences for human health and property, maintaining a safe and healthy environment is critical for gas station workers and customers.
This is why my teamTo this end, we carried out the first-ever study of fire risk assessment in fire hazardous zones (FHZ) at gasoline stations in Thailand. A fire hazardous zone can be divided into two parts: FHZ-I is a 1.5- meter radius around the fuel dispenser and refuelling area, where a mixture of gases in the atmosphere alongside a real risk of fire ignition during operating hours, and maintenance or flammable leakage persists for most of the year,; and FHZ-II is a 1.6- to 5five- meter radius of the fuel dispenser area, where the mixture of gases in the atmosphere and the risk of fire ignition is present for a short period of time.
After We collected ing data from 47 stations, we and found that there was an approximate a shocking 85%.11 intolerable level of percent risk of fires in FHZ-I as compared to FHZ-II. This could be because of the presence of high concentrations of flammable gas that could ignite and explode. Only FHZ-II showed a moderate risk level at times, with only 21.28% percent of the stations having an intolerable level of risk and 38.30 percent having a substantial risk. The main source of a fire igniting came from workers using electronic devices in FHZ-I. A significant correlation was discovered between fire risk levels in FHZ-II, the quantity of fuel sold and a station's location, with a higher health risk among workers at urban and suburban gas stations as compared tothan those in the rural ones. No vapor recovery systems were installed in any of the stations.
Our study indicates a clearly shows the need for regular inspections, posters signalling fire hazardous zonesand, the strict prohibition on mobile phones within these zones, and as well as the installation of electrostatic discharge equipment and lightning conductors to alleviate fire risk.
