What should I do if I smell gas near a cooker or other appliance?

Leave the home immediately. If you smell or hear gas leaking, do not operate electronics—including lights or phones—before leaving; contact local gas authorities from outside. [S1]

Do not pause to inspect the cooker, test for a leak, or try to repair the appliance. The key is to get outside first, then make contact. This guidance is for a suspected gas leak, not for diagnosing the appliance.

Do not operate electronics before leaving. The cited guidance specifically includes lights and phones. [S1] Don’t delay your exit to operate controls or investigate the source. The source does not give instructions for manipulating cooker controls, so this guide does not add a shutoff procedure.

Once you are outside, contact your local gas authorities. If you need to find their number, do that from outside—not by using a phone inside the home. [S1]

The guidance applies if you smell or hear gas leaking; it does not provide a method for deciding whether a smell is gas or identifying which appliance is responsible. [S1] Don’t try to settle that uncertainty by staying inside to test or inspect. Leave immediately and contact local gas authorities from outside. [S1]

For example, if you notice a suspected gas smell near a cooker, heater, or another appliance, use the same response: leave, avoid operating electronics on the way out, then contact the local gas authority from outside. This is not a diagnosis of the appliance.

Contact your local gas authorities from outside and follow their instructions. [S1] The supplied guidance supports that next step, but it does not specify what they will ask you to do or provide a procedure for checking the appliance. Keep the response simple: make contact from outside rather than going back in to investigate or attempt a repair.

Copy and fill in only the placeholder before an incident:

GAS SMELL OR SOUND — RESPONSE

1. Leave the home immediately.
2. Do not operate electronics, including lights or phones, before leaving.
3. Once outside, contact local gas authorities: [local gas authority contact details].
4. Follow the instructions they give you.

Steps 1–3 reflect the cited CPSC guidance. [S1] The source supports leaving and contacting local gas authorities from outside; it does not establish how to test for a leak, which appliance is responsible, or how to repair one. Do not use this card as a troubleshooting or repair guide.
