Yes, it contain methane.
There are several ways but be really careful as methane and other highly flammable sewer gases can cause a violent explosion and death by asphyxiation

Sewer gases from an island sink can be harmful if inhaled over a long period of time, as they contain toxic substances such as methane and hydrogen sulfide. Short-term exposure may cause symptoms like headaches, dizziness, or nausea. It's important to properly vent the plumbing system to prevent the buildup of these gases and ensure good ventilation in the area.
The purpose of a basement sewer trap is to prevent sewer gases from entering a building. It functions by creating a water seal that blocks the gases from passing through the plumbing system and into the building.
I'm not a professional plumber, but fairly experienced with plumbing. From what I understand, a p-trap allows for a small pool of water that acts as a barrier between the nasty stuff down your drain, ie. poisonous gases and smells. It also can catch bigger stuff that shouldn't be going down the drain and block it in a generally easily accessible spot, versus clogging up further down the line. It is certainly required by plumbing codes and should the sewer/septic gases build up they can cause illness/death or cause an explosion.
To prevent dangerous waste /sewer fumes from entering a structure
Yes, sewer gas is flammable and can explode if it comes into contact with an ignition source like an open flame or spark. It is important to address any issues with sewer gas leaks promptly to prevent the risk of an explosion.
methane gas
Yes
YES it can if explosive gases are present. Use a atmospheric testing device to check for LEL (lethal explosive limits) before cutting!!!! If gases are present I suggest you use a vent blower to remove the explosive gases before cutting or even better hire a professional with a license and insurance.
The sewer smell in your house after rain may be due to a backup or blockage in your plumbing system, which can cause sewer gases to escape into your home. The rainwater may also be causing the sewer lines to become overloaded, leading to the smell. It is important to address this issue promptly to prevent any potential health hazards.
To prevent harmful effects of sewer gases in your house, ensure proper ventilation, regularly inspect and maintain plumbing systems, install traps and vents, and consider using a sewer gas detector.
