INITIAL DATA FOR VARIANT 18
Profession: A window manager for installation of double-glazed windows
Possible trauma: Back injury
Frequency of trauma: Once every 5 years
Severity of consequences: Severe injury, loss of occupational ability
The work of a window manager includes transportation, lifting, positioning and fixing of heavy double-glazed units. Therefore, the main risk is connected with excessive physical load on the spine, awkward working posture and manual handling of heavy glass structures.

TABLE 2. Hazardous Production
Physical overloads: lifting and carrying heavyFactorsdouble-glazed windows, awkward postures, dynamic overloads and strain of the
back muscles.
Location of workplaces at height relative to the floor or ground surface.
Falling objects: tools, elements of equipment, transported window blocks.
Sharp edges, burrs and roughness on surfaces of glass, frames, tools and equipment.
Moving products, blanks and materials during transportation and installation.
Increased noise and vibration from a drill or perforator.
Increased dust level and insufficient illumination of the working area. Increased voltage in the electric circuit when using power tools.

Risk Assessment (according to the
Trauma: Back injury. matrix)
Severity of consequences: Severe injury, loss of occupational ability.
Frequency: Once every 5 years.
Risk: High (Severe + Once every 5 years = High). The risk is not acceptable; changes are required before routine work.

|
Situation: The worker carries a heavy glass unit by hand for a long distance without lifting equipment
Situation: The worker lifts the window unit from the floor with a bent back
Situation: The workplace is blocked by tools, packages or construction waste
Situation: The worker fixes the window frame while standing in an uncomfortable bent position
Situation: Several workers move the glass unit without clear commands
Situation: The same worker lifts heavy window units many times during the shift without rotation
Measure: Use a trolley, hoist, suction cups or vacuum lifter for heavy window units
Measure: Train workers to lift with a straight back and use leg muscles
Measure: Clean the workplace before work and keep transport routes free
Measure: Use temporary supports and stable platforms during installation
Measure: Choose one person to give commands during team lifting
Measure: Rotate workers, limit repeated lifting and introduce rest breaks

CONCLUSION
The occupational risk for a window manager installing double-glazed windows is assessed as High. The main cause of this risk is manual handling of heavy glass units, especially during lifting, carrying and positioning in the window opening.
The priority measures are technical and organisational controls. Heavy window units should be moved with trolleys, suction cups, hoists or vacuum lifting devices. The workplace and transport route must be prepared before work starts, and team lifting must be performed only with clear coordination.
Personal protective equipment is required, but it cannot remove the main cause of the risk. Therefore, the most important objective is to reduce manual lifting, avoid twisting of the spine and prevent excessive physical load on
the worker’s back.
