IF YOU SMELL GAS

1. NO FLAMES OR SPARKS! Immediately put out all smoking materials and other open flames. Do not operate lights, appliances, telephones, or cell phones. Flames or sparks from these sources can trigger an explosion or a fire.
2. LEAVE THE AREA IMMEDIATELY! Get everyone out of the area where you suspect gas is leaking.
3. SHUT OFF THE GAS. Turn off the main gas supply valve on your propane tank if it is safe to do so. To close the valve, turn it to the right (clockwise).
4. REPORT THE LEAK. From a neighbor’s home or other nearby building away from the gas leak, call your local gas company right away. If you can’t reach your gas company, call 911 or your local fire department.
5.  GET YOUR SYSTEM CHECKED. Before you attempt to use your generator, the gas company or a qualified service technician must check your entire system to ensure that it is leak-free.

CAN YOU SMELL IT?

Natural Gas itself is odorless and tasteless, but a chemical is added to give it an odor in order to help detect leaks quickly. Natural Gas is lighter than air and will collect in higher areas.
Since there is a possibility of odor loss or problems with your sense of smell, you should respond immediately to even a faint odor of gas.

NATURAL GAS DETECTORS

Under some circumstances, you may not smell a natural gas leak. Natural gas detectors sound an alarm if they sense natural gas in the air. They can provide an additional measure of security. You should consider the purchase of one or more detectors for your home.

GUIDELINES regarding natural gas detectors

• Buy only units that are listed under the latest Underwriters Laboratories (UL) standard.
• Follow the manufacturer’s instructions regarding installation and maintenance.
• Never ignore the smell of gas, even if no detector is sounding an alarm.

GENERATOR MAINTENANCE

LEAVE IT TO THE EXPERTS. Only a qualified service technician has the training to install, inspect, service, maintain, and repair your generator. Have your generator inspected just before the start of each heating season.
DO NOT TRY TO MODIFY OR REPAIR valves, regulators, connectors, controls, or other generator and cylinder/tank parts. Doing so creates the risk of a gas leak that can result
in property damage, serious injury, or death.

CO AND YOUR SAFETY

WHAT IS CARBON MONOXIDE (CO)?
You can’t taste or smell CO, but it is a very dangerous gas. High levels of CO can come from appliances that are not operating correctly, or from a venting system or chimney that becomes blocked.
CO CAN BE DEADLY! High levels of CO can make you dizzy or sick. In extreme cases, CO can cause brain damage or death. Symptoms of CO poisoning include: headache, dizziness, fatigue, shortness of breath, and nausea.

IF YOU SUSPECT CO IS PRESENT, ACT IMMEDIATELY!

1. If you or a family member shows physical symptoms of CO poisoning, get everyone out of the building and call 911 or your local fire department.
2. If it is safe to do so, open windows to allow entry of fresh air, and turn off any appliances you suspect may be releasing CO.
3. If no one has symptoms, but you suspect that CO is present, call your propane retailer or a qualified service technician to check CO levels and your propane equipment.

CO DETECTORS CAN IMPROVE SAFETY. For an extra measure of safety, consider installing a CO detector listed by UL on each level of your home.

TO HELP REDUCE THE RISK OF CO POISONING

• Have a qualified service technician check your propane appliances and venting systems annually, preferably before the heating season.
• Install UL-listed CO detectors on every level of your home.
• Never use a gas oven or range-top burners to provide space heating. Never use a barbecue grill (propane or charcoal) indoors for cooking or heating.
• Regularly check your appliance exhaust vents for blockage.

    Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

15. Never use a generator indoors, including in garages, basements, crawl spaces and sheds. Opening doors and windows or using fans will NOT prevent carbon monoxide build up in the home.

16. When using generators, keep them outdoors and far away from open doors, windows, and vents to avoid toxic levels of carbon monoxide from building up indoors.

17. Install carbon monoxide alarm(s) with battery backup in nearby buildings according to manufacturer’s instructions.

18. Maintain product labels and nameplates.
