Residual risks
Residual risks imply potential hazards for the operator due to
incorrect work practices that are impossible to eliminate or
can be eliminated only in part.
Work environment
The user must ensure that the working environment or
any material in the vicinity of the actuator do not reduce
the safety level required for the proper functioning of the
actuator.
The user must ensure that the actuator is duly protected from
the environment, including – among other factors – lightning,
vibration sources and vehicle movements.
Prior to installing the actuator in potentially
explosive areas, verify that the safety requirements
specified on the nameplate are compatible with
the plant requirements. Install the actuator only in
the potentially explosive area for which it has been
designed.
The final user is to provide the staff operating the
actuator or the adjacent equipment with the necessary
procedures and training to avoid additional risks.
Residual risk:
Actuator/valve installed in the plant in a way that prevents
personnel from moving around easily and/or so that work
and/or emergency exit ways are blocked or impassable.
Prevention measure:
The final user must place the actuator/ valve without
jeopardising the safety of the staff. The final user must also
make sure that transit areas are correctly built so that the
staff can enter or exit the work area safely; transit areas must
be kept clean of equipment, materials, debris or anything that
could obstruct the passage.
Residual risk:
Tripping up, slipping and consequent falls due to floor
irregularities or oil spills, grease or products that make the
floor slippery in the area of the actuator including transit
ways.
Prevention measure:
The user must make sure that the work area around the
actuator is safe, clean and free of any kind of obstacle.
Possible losses of fluid must be eliminated and possible
deposits must be removed and cleaned. Operators should
wear safety shoes.
Residual risk:
Protruding parts and sharp corners on the actuator can be a
safety and/or health hazard for the staff, especially in case of
falls.
Prevention measure:
The user must confine the work area around the actuator
and access must be permitted only to qualified staff wearing/
using appropriate PPDs.
Residual risk:
Human error due to a failure to comply with procedures and/
or safety instructions.
Prevention measure:
Use of/wearing suitable PPDs to reduce the effect of such
risks to the minimum.
Residual risk:
The user fails to verify the compatibility of the ATEX
protection directives specific for the actuator with that of the
installation area.
Prevention measure:
It is the user’s responsibility to verify all the documentation
concerning the actuator and the name plate displaying the
ATEX protection.
