NO to carbon monoxide!

What is carbon monoxide? Carbon monoxide is a colorless and odorless highly toxic gas. It enters the body through the respiratory system and then gets absorbed into the bloodstream. It hinders the proper distribution of oxygen in the blood and causes damage to the brain and other organs.
If you use coal and wood, perform periodic inspections at least once every three months. When using natural gas or heating oil – at least once every six months. The building manager or owner is obliged to, among other things, inspect the ventilation system at least once a year.
