10. November 2022·Technická inšpekcia, a.s.
Verification of compliance with machine safety requirements pursuant to Section 14, Paragraph 1, Letter d) of Act No. 124/2006 Coll.
- Machine identification is missing (manufacturer’s name and address, series or type designation, serial number, and year of manufacture).
- Insufficient lighting of workplaces and internal working areas of machinery corresponding to work operations (internal and external lighting of machinery).
- The control system is not safe and reliable enough to prevent hazardous situations.
- Machine control and monitoring elements are not clearly visible, identifiable, and appropriately marked, nor are they positioned to allow for guaranteed, error-free, quick, and unambiguous operation.
- The machinery can be started unintentionally. This unintentional start-up of machinery is also possible during restart after it has been stopped for any reason.
- Each workstation of the machinery is not equipped with a control device to stop certain or all moving parts of the machinery. The command to stop the machinery must override the commands to start the machine. After stopping the machinery or its dangerous parts, the power supply to the respective drive unit must be interrupted.
- The machinery is not equipped with an emergency stop device in justified cases.
- The machinery is not equipped with an operating mode selector (switch) that can be locked in any position.
- Due to its shape or specified installation (insufficient stability), the machinery lacks means for anchoring.
- Accessible parts of the machinery have sharp edges, sharp corners, and rough surfaces that could cause injury.
- Moving parts of the machinery create mechanical hazards – a risk of contact that could cause injury. The machinery is not equipped with guards or protective devices.
- The machinery is not equipped with appropriate fixed and/or movable (including adjustable) protective guards and/or other protective devices (e.g., light curtains and screens, footbridges, etc.) to protect against hazards from moving external parts (such as drive pulleys, belts, gears, etc.) or moving working parts in the working area. Protective devices are not adjustable only by deliberate manipulation (e.g., with a tool, key, etc.).
- The machinery has accessible surfaces (media lines) with high or very low temperatures, posing a risk of injury.
- The machinery poses a risk of fire or overheating (* or caused by gases, liquids, dust, vapors, or other substances generated or used in the machinery).
- The machinery exceeds the permissible noise emission.
- The laser equipment of the machinery has insufficient shielding against radiation generated by reflection or scattering, including secondary radiation.
- The machinery poses a hazard due to emissions of gases, vapors, liquids, or dust, etc. The equipment is not fitted with a suitable extraction or protective device located at the source of the hazard.
- Access to the operating position (stairs, ladders, work platforms, etc.) is not designed to prevent slipping, tripping, or falling on or from these parts.
- The machinery does not have safe access to all areas important for operation during work, adjustment, and maintenance.
- The machinery is not equipped with a means to disconnect from all energy sources – a central controller.
- The central controller is not clearly marked and lockable.
- The warning device does not meet the requirements of specific regulations concerning safety colors and signs.
