Lift as Subject of Risk Analysis in the Context of Smart Buildings

A Review of Relevant Regulations, Requirements and Assessment Methods Concerning Physical Load in Workplaces in the Slovak Republic

“…The minimum height of individual upper seat adjustment in the neutral position to the given table (inclination of the torso axis 4°) is equal to the difference in height of the upper surface of the table and the olecranon point in abduction 20° above the seat. The maximum height of the individual adjustment of the upper surface of the seat is equal to the difference between the height of the upper surface of the table and the olecranon point perpendicular to the floor with a torso forward tilt of 24°, which is the value of the angle after correction for the neutral position of the torso (20° + 4°) of the employee to the table [21][22][23][24][25]. A free space for the lower limbs with a minimal width and depth of 50 cm and a minimal height of 60 cm above the floor, or lower limb support (in which the optimal width and depth of the space for lower limbs is 70 cm or more) is required for a sitting work position.…”

“…Space for movements and reaching of the upper limbs when working while sitting and standing is adjusted according to Figure 3 [9], in which: the handling plane is the plane in which the most work operations are performed; the reference plane is the base plane for deriving other dimensions and spatial relationships; reference plane A is a plane which is perpendicular to the floor and imaginarily divides the employee into symmetrical halves at the workplace; reference plane B is the floor; reference plane C is the plane perpendicular to the floor and passes through either the front edge of the table or the point of the machine nearest to the worker. The workplace reference point is where reference planes A and C intersect one another with the manipulation plane for men and women [21][22][23][24][25]. The pressures allowed when using the controllers are given in Table 1, in which: permanently used controllers are used more than 40 times during a work shift; frequently used controllers are used more than 20 to 40 times during a work shift; rarely used drivers are the ones used less than 20 times during a work shift [21][22][23][24][25].…”

“…When using the muscles of the upper limbs in a standing position, all values given in Table 2 will be reduced by 20%; when using both upper limbs in a sitting position or one upper limb in a standing position, the values given in Table 2 are reduced by 50%; when using one upper limb in a sitting position, the values listed in Table 2 will be reduced by 75%; if both lower limbs are being used, it is evaluated as work with the whole body [21][22][23][24][25].…”
