Machine Safety Dictionary Machine - an assembly powered by a drive other than that of animal or human musclesActivation of protective equipment - the starting time of the protective equipment operation when motion is detected Risk analysis - identification of hazardous persons Security - no risk Complete system halt - the machine stops working Access time - time to reach the components of the hazardous machine Access frequency - number of actions to access the protection zone per unit of time Defect - the inability to perform the function by the object, does not include maintenance and planned repairs; Hazardous Defect - Hazardous Defect; a defect that does not change the security status - a defect that does not affect the security status Safety features: basic - disturbance causes danger unconditional - they provide security conditional - do not apply to the safety function indirect - interference does not cause immediate danger, but reduces its level Electro-sensitive protective equipment (EWO) - self-protection components, sensing, control and monitoring equipment switching input signals Safety-related elements of control systems - they emit input signals Safety functions of control systems - are responsible for the safety of the machine Function endangering the machine - function causing the threat Usage Information - security measures, including signs, symbols, graphs, inscriptions Isolating and dissipating energy - disconnecting the machine, closing insulated components, dissipating or holding back energy, checking the effectiveness of the procedure Category - fragmentation of safety control system components Position switch - it is acted on by a moving element of the machine Reliability - the ability of the machine to work without failure in specific conditions and periods Risk assessment - includes economic, environmental and social factors Safety distance - the distance between the protection zone and the danger zone Operator - a person performing installation, maintenance, repair works and operating the machine Cover - the protective part of the machine; permanent cover - permanently connected to a given place; movable cover - can be removable; adjustable guard - has an adjustable position; locking cover - equipped with locking parts; control guard - equipped with blocking parts that prevent operation when the guard is not closed Susceptibility to repair and maintenance - adjusting the machine to return to safe working condition Reasonably foreseeable misuse - use of the machine in conditions unsuitable for this Redundancy - using a different machine, part or system after a failure to ensure the continuity of work Reset - restoration of safety functions Risk - the chance of the damage and its severity; tolerated risk - accepted in certain circumstances Self-supervision - supervision that automatically enables safety measures in the event of a reduction in the ability of a part to perform its function Zone dangerous - causes exposure to injuries Situation threats - causes exposure to threats Pity - damage to health, property or environmental degradation Means safety - intended to reduce the risk and achieve a tolerable risk Means protective - necessary to protect people from dangers that cannot be completely eliminated Activation machinery - starting operation of the machine or its element; unexpected start-up - caused by damage, power return, improper action on the control element, impact of the machine, engine self-ignition Device blocking - prevents the machine element from working Device protective - reduces the risk Device supervising run - transmits a signal preventing the next switching on of the machine Self-acting distance device - switches off the machine or its elements when entering the protection zone Limiting device - prevents the device from exceeding the partition values Mechanical restraining device - having a mechanical barrier Locking device - closing the machine guard Supported control device - in operation until the control element is actuated Two-hand control devices - requires the use of two hands Step control devices - they allow you to work only in a given part of the room Devices that restrict access - are physically limited to the danger zone Enabling control devices - when started manually, it enables work Damage - the machine is not able to work Using the machine as intended - proper use of the machine Danger - puts you at risk of injury Suspension - suspension of the safety functions while the machine is running Happening harmful - takes place if the emergency turns into a damage Detection Ability - sensitivity parameter enabling the protective equipment
