Q: "I have anosmia, i.e. I have lost my sense of smell. We have natural gas heat, a natural gas water heater and a natural gas cooking stove. I cannot smell a gas leak. Which gas detector do you recommend?"
Answer: Currently, we sell three brands of combustible gas alarms.
Two brands are UL1484 listed for use with natural gas and propane gas and also work with gasoline fumes and butane fumes. These are the Safe-T-Alert 40-411AC and the Safety Siren Combustible Gas Alarm and the Safety Siren CO and Combustible Gas Alarm.
The advantage of the Safe-T-Alert is the long cord for proper positioning of the detector, i.e. high and near the appliance for natural gas and low and near the appliance for propane. We also sell the Safe-T-Alert in a 230VAC unit for Europe and Asia. The Safety Siren unit is a direct plug in with a safety tab that the outlet plug screw goes through so the unit cannot be easily removed. Most customers who buy the Safety Siren model install an electrical outlet at the proper height for natural gas or propane.
All our combustible gas alarms sound at less than 25% of the lower explosive or flammable level of the gas.
Please contact us if you have further questions.
Sincerely, Barbara
