The article presents the results of a study of the shrinkage of pine wood damaged by a strong grassroots and runaway wildfire after storage in room conditions for 10 years. Experimentally, an increase in the shrinkage of pine wood damaged by fire at its humidity of 30 % in the tangential direction was on average 7 %, in the radial direction – 6,6 %. The nature of the shrinkage change in the radial direction is close to linear, both for fire–damaged and undamaged wood. In the tangential direction, the shrinkage value of fire-damaged wood increases sharply when its humidity is less than 5 %. Wood damaged by fire can be used in products without significant restrictions.
