The Town of Mammoth Lakes and Mammoth Lakes Fire Department would like to remind residents of several life safety issues. These include the accumulation of large amounts of snow/ice on roofs, the blockage of vents for heating and hot water appliances, and the maintenance needed to safely use propane. Additionally, we request that residents keep property addresses visible and fire hydrants cleared.
Excessive Snow Loads & Roof Shedding
With the large accumulations of snow this season, our roofs are already supporting a tremendous load. Some signs of excess snow weight on the roof include exterior/interior doors that do not open or close easily, cracks or bulging that occur in sheetrock walling, and bowing in timber members of ceilings/walls. Existing structures should be able to structurally withstand current snow loads, but it is recommended that you remove snow to prevent excessive snow accumulation. Even if all of the snow and ice cannot be removed, removing at least the top half to two thirds of the roof snow pack is very beneficial. As temperatures rise, roofs will shed snow and ice, especially metal roofs. Be extra careful where you walk and where children play, especially at all exits and entries. Keep your head up! Please contact the Town of Mammoth Lakes Building Division at (760) 965-3635 if you are concerned with the structural integrity of your property.
Propane Tanks and Vents
For those homeowners that use propane, several responsibilities come with its use. The top of the tank needs to be routinely dug out and cleared to allow access to the shutoff valve and regulator venting. In addition, make sure that unprotected sections of all exterior gas pipes are cleared of snow/ice and protected from shedding snow and ice from your roof. Downward snow pressure from snow settlement and falling snow/ice from roofs has caused many pipe sections to crack resulting in leaks. Unfortunately, if the leak occurs under the snow, the snow traps the gas and it may be some time before the leak is detected. Homeowners, landlords and tenants need to make sure that vents for appliances are cleared of snow and inspected so that a build-up of carbon monoxide inside does not occur. It is highly recommended that carbon monoxide detectors be installed inside structures in order to alert occupants to the build-up of carbon monoxide gas. Call the MLFD at (760) 934-2300 for additional information.
