The Main Dangers & Hazards of EN 115 Escalator StandardAll the main dangers, hazards and issues of the EN 115 standard based on EN ISO 12100:2010) for escalators and moving walks have been stated and covered below, which the user must be aware of and take action on.
Mechanical Dangers & Hazards
If the machine design or access to it is faulty, the mechanical dangers below can occur on escalators & moving walks and surrounding areas:
1- Touching out of the way or encased moving machinery parts like drive units and handrail drives
2- Fingers are crushed or sheared between handrails and balustrades and other spaces & gaps
3- Adjacent cover profile parts cause cuts and injuries
4- Physical injury due to crashes with walls, roofs and criss-cross arrangements or with people on adjacent escalators or moving walks
5- Incidents at the gap where the handrail enters the balustrade
6- Incidents and being trapped at the gap between the skirting and steps and between comb and step/pallet
7- Incidents and being trapped at the gap between the floors or fixed devices and the handrail
8- Incidents and being trapped at the gap between step and step or pallet and pallet
Electric Dangers & Hazards
The reason for electric dangers & hazards are:
1- Direct and indirect contact by people with live parts
2- Lack of emergency stops
3- Incorrect electric component assembly
4- Electrostatic issues
5- External effects on electric equipment
Radiation Dangers & Hazards
Radiation hazards can include the following:
1- Generation of electromagnetic radiation while operating normally.
2- Outside Electromagnetic radiation such as low frequency radiation, radio frequency radiation or microwaves while operating normally.
Fire Dangers & Hazards
The parts contained in the truss including plastic material can catch fire and be hazardous due to other combustible material.
Neglect of Ergonomic Principles
Neglect of ergonomic principles in machinery design can create the following dangers & hazards:
1- Lack of consideration of ergonomic dimensions for the users such as height of balustrade, width of handrail, etc.
2- Unsuitable lighting in the work places and blocked access to lighting
3- Unsuitable space in the work places
4- Unavailable lifting equipment for heavy loads
Failure of Control Circuits Dangers & Hazards
Dangers and hazards can occur because of below items:
1- Machine operates without stoppage in emergency situations
2- Electric wiring short circuits
3- Electric wiring overloads
4- Sudden restart of machine after an interruption
5- Sudden reversal of the drive
6- Unexpected changes in speed
7- Sudden deceleration of speed during stopping
Dangers & Hazards Caused by Break-up During Operations
Dangers caused by break-up during operations, despite the fact that the design of an escalator or moving walks follows the EN 115-1 requirements are mentioned below.
1- The truss suffers loads greater than specified by user and structure
2- The balustrade suffers loads greater than specified
3- The steps/pallets suffer higher loads than specified
4- The drive unit suffers loads greater than specified
Slipping, Tripping and Falling Dangers & Hazards
The most significant dangers & hazards for escalators and walks are slipping and falling of people, categorized as below:
1- Slipping on steps/pallets/belt, the comb plate or floor plate
2- Falling due to handrail speed deviation including standstill
3- Falling due to changes of the direction of movement
4- Falling due to changes in acceleration/deceleration
5- Falling due to unexpected starting/stopping or sudden speed changes
6- Falling due to insufficient lighting at the landings
Escalator and Moving Walk Specific Dangers & Hazards
1- Incidents due to missing steps or pallets
2- Being trapped by hand winding/flywheel devices
3- - Incidents due to transportation of items (shopping, luggage trolleys, pushchairs) other than people
4- Incidents due to climbing on the outside of, sliding between or climbing over the balustrades
5- Incidents due to sliding or surfing on the handrail
6- Incidents due to storage of goods (luggage, etc.) adjacent to the balustrade
7- Incidents due to crowding at exit landings or other connecting spaces of escalators or moving walks
8- Incidents due to disturbance by other people at connected areas of escalators/moving walks
9- Incidents due to lifting or pulling in of objects which are close to the balustrade by handrails at the newel ends
Major Seismic Event Dangers & Hazards
Major seismic event dangers include damage to equipment and crushing by displacement of equipment
Remember that noise is not a significant or relevant hazard.
