Which risk significantly elevates when isobutane leaks next to HVAC compressor?

💡 Explanation

Leak of isobutane refrigerant concentrates and ignites forming a large vapor which is caused by a lower ignition energy leading to quick combustion reactions; because hydrocarbon refrigerants are flammable, explosive vapor cloud development occurs surrounding HVAC compressor apparatus, therefore combustion occurs rather than other gradual pressure decreases.
