Construction is the sector where the number of accidents in workplaces is the highest among all sectors. According to the State Labour Inspectorate, many employees suffer in accidents each year, a large proportion of which have been severe, or even fatal, and their number tend to increase. Performing work at height is one of the most significant risks directly in the construction sector. Of course, at construction sites, in order to perform specific construction works, lot of the work is carried out at height. When paying attention to these problems, experience has shown that the use of appropriate collective protective equipment and measures would make it possible to prevent a large part of all accidents. While surveying construction sites within the scope of the study, the authors conclude that it is the collective labour protection equipment and measures that receive too little attention, the emphasis is placed on individual protection equipment, although the Labour Protection Law in Latvia stipulates that priority should be given directly to collective labour protection equipment. The aim of the research work was to identify the main problems on construction sites, which arise as a result of planning and use of incorrect or insufficient collective labour protection equipment, to collect and analyse the acquired information, to provide proposals for improvement of collective protection equipment and measures on construction sites. Within the framework of the study performed, the authors of the article propose to perform regular procurement's in addition to the existing measures exactly for collective labour protection equipment in the construction object, the labour protection specialist in the enterprise should be ensured with all necessary measuring equipment in order to fully perform the assessment of the risks of the work environment, perform mandatory register of collective labour protection equipment and quality control at construction sites, etc
