It seems to be this is happening more often, in the UK not so, but we have had a several buildings going up in flames during renovation.

Health and safety law(s) exist for the very reason to prevent things like this, it seems people cut costs by cutting corners resulting in preventable accidents, which either lead to environmental damage, death and or injury.

Regulations and laws are fine, Any hazardous activity needs to have proper safeguards in place and the funding to ensure those safeguards are effective.
