Safety measures in stone quarries are investigated through a questionnaire for safety requirements and the degree of compliance distributed to managers and workers of selected quarries in northern Jordan. Responses showed that while health and technical safety measures are applied in most quarries, safety awareness measures are unimplemented in all surveyed quarries despite the claim by quarry managers and workers that awareness programs do exist. Preliminary results indicate a correlation between the level of education and experience of both quarries managers and workers and the frequency and severity of work accidents.

The article presents results of the granulometric composition of chip particles when sanding wood (beech) and wood-based materials (particleboard and semi-hardboard) using different types of sanders – wide belt sander, narrow belt sander, and hand sander. On the basis of the carried out sieve analyses, the proportion of produced particles, which can be marked as dust with the particle size of ≤ 80 μm, is high at the interval from 89.21% - 96.29 %. The highest percentage of dust particles was reached at dust from the hand disk sander. At the end of the article we point to possible technical safety measures – additional dust exhausting, suction, to possibly reduce the dust getting to the working environment.

For goaf group and high grade embedded residual ore in NO.I ore body, the overall technical idea of pre-filling the key goaf, the residual mining and the non-key goaf filling is used. The goaf management was mainly based on waste rock filling and supplemented with cemented filling, which formed safe mining environment in the upper, lower isolation belts and efficient management in hidden danger goaf. For rib pillars with cemented rock filling and waste stone filling on both sides of goaf, the method of upward horizontal common layered and small layered filling with pointed pillars were employed respectivly. For the crown pillar overlying high strength of filling body and waste rock, the united method of upward horizontal layered filling with entrance filling and caving are separately employed. Regional and local multidimensional integrated monitoring system were built subsequently. Then, relevant technical safety measures were taken. This study is to achieve the goal of safe, efficient and economical goaf management and residual mining.

A great number of injuries when performing the work at height are recorded when falling from the stairs. Injuries due to falling from height including ladders are usually severe and even fatal. At the same time, about 70 % of injuries occur with portable ladders. Most often, the fall of a person is caused by the effect of sliding ladders and breaking the stability of its overall structure. One of the ways to increase the stability of the ladder is to use attachments on its upper part. Depending on the method of coupling with the support, the possibility of adjusting the coupling area, as well as the presence of built-in safety systems, different types of attachments are used. The article considers the forces that cause the slip and fall of the ladder when using it in work. Engineering solutions aimed at preventing the upper part of the ladder from slipping while working on the support are presented. The systematization is carried out concerning the available attachments on ladder by the method of coupling with the support. The evaluation of these engineering solutions in various ways of their application is carried out. A mathematical model is proposed for risk assessment when performing work at height using ladders with attachments. The stability of the ladder with the attachment will be higher, the greater the coefficient of friction of the attachment and the less degrees of freedom of movement in the «attachment — support» bundle. An empirical conclusion is made that the safest attachment at the top of the ladder will be the structure that is fixed on the support. The attachment with an anchor point ensures the safety of work at height, but it is not suitable in all cases. There is no universal effective engineering solution to ensure the safety of work at height from the ladder. Technical safety measures have great potential, since they allow eliminating the human factor in this process.
