is there a risk of exploding with this gas?
Yes
Natural gas
Explosions caused by natural gas leaks occur a few times each year.

Natural gas [SEP] Risk of explosion
Explosions caused by natural gas leaks occur a few times each year. Individual homes, small businesses and other structures are most frequently affected when an internal leak builds up gas inside the structure. Frequently, the blast is powerful enough to significantly damage a building but leave it standing. In these cases, the people inside tend to have minor to moderate injuries. Occasionally, the gas can collect in high enough quantities to cause a deadly explosion, disintegrating one or more buildings in the process. Many building codes now forbid the installation of gas pipes inside cavity walls and/or below floor boards to mitigate against this risk.
