CLEARING SNOW AND ICEBUILD UP FROM EQUIPMENT

摘要

As winter approaches, natural gas distribution companies are urging customers and the general public to be aware of the risks posed by heavy snow and ice build-up around natural gas equipment and of the importance of safely clearing this snow and ice build-up. The accumulation of snow and ice increases the potential for damage to meters and regulators and other aboveground pipe components. Incidents can occur on natural gas equipment related to either the stress of snow and ice or due to ice blockage of gas appliance vents or chimneys. Exposed piping at meters and pressure regulators, and at propane tanks, are at greatest risk. Damage may result from the stresses imposed by the additional loading of the snow or ice. Damage to facilities may also result from the impact of snow or ice falling from roofs, ice forming in or on meters and regulators preventing their proper operation, or shovelling snow from roofs to protect dwellings from abnormal snow accumulation on to gas or propane equipment and appliance vents.
