ISO 45001:2018 does not state specific criteria for OH; &S performance, nor is it prescriptive about the design of an OH; &S management system.
ISO 45001:2018 enables an organization, through its OH; &S management system, to integrate other aspects of health and safety, such as worker wellness/wellbeing.
ISO 45001:2018 does not address issues such as product safety, property damage or environmental impacts, beyond the risks to workers and other relevant interested parties.
ISO 45001:2018 can be used in whole or in part to systematically improve occupational health and safety management. However, claims of conformity to this document are not acceptable unless all its requirements are incorporated into an organization's OH; &S management system and fulfilled without exclusion.

This document specifies safety requirements and the means for their verification for driverless industrial trucks (hereafter referred to as trucks) and their systems.
Examples of driverless industrial trucks (trucks as defined in ISO 5053‑1:2020) include: “automated guided vehicle”, “autonomous mobile robot”, “bots”, “automated guided cart”, “tunnel tugger”, “under cart”, etc.
This document is also applicable to driverless industrial trucks which are provided with:

For the purposes of this document, a driverless industrial truck is a powered truck, which is designed to operate automatically. A driverless truck system comprises the control system, which can be part of the truck and/or separate from it, guidance means and power system. Requirements for power sources are not covered in this document.
The condition of the operating zone has a significant effect on the safe operation of the driverless industrial truck. The preparations of the operating zone to eliminate the associated hazards are specified in Annex A.
This document is applicable to all significant hazards, hazardous situations or hazardous events during all phases of the life of the truck (ISO 12100:2010, 5.4), as listed in Annex B, relevant to the applicable machines when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.
In particular, this document does not apply to significant hazards related to:
—    noise;
—    vibrations;
—    ionising and non-ionising radiation;
—    laser radiation;
—    sales literature (commercial documents);
—    declaration of vibrations transmitted by mobile machinery.
It does not apply to additional hazards that can occur:
—    during operation in severe conditions (e.g. extreme climates, freezer applications, strong magnetic fields);
—    during operation in nuclear environments;
—    from trucks intended to operate in public zones (see in particular ISO 13482:2014);
—    during operation on a public road;
—    during operation in potentially explosive environments;
—    during operation in military applications;
—    during operation with specific hygienic requirements;
—    during operation in ionizing radiation environments;
—    during the transportation of (a) person(s) other than (the) intended rider(s);
—    when handling loads the nature of which can lead to dangerous situations (e.g. molten metals, acids/bases, radiating materials);
—    for rider positions with elevation function higher than 1 200 mm from the floor/ground to the platform floor.
This document does not contain safety requirements for trailer(s) being towed behind a truck.
This document does not contain safety requirements for elevated operator trucks.

This document specifies the characteristics and the requirements of unrestricted air gap Family A, Type A for nominal flow velocity not exceeding 3 m/s. Air gaps are devices for protection of potable water in water installations from pollution by backflow. This document applies to air gaps in factory-assembled products and to constructed air gaps in situ and specifies requirements and methods to verify and ensure compliance with this document during normal working use.
The fluid in the receiving vessel is assumed to have similar properties to the water supply. Where this is not the case, additional care or tests could be required to verify the efficacy of the solution in practical use.
The AA device is intended to be used in potable water installations according to EN 806 (series).
Sanitary tapware when installed onto a receiving vessel (e.g. washbasin etc.) might have some restriction of its overflow. This will not compromise the water supply as the tapware might have an air gap, as detailed for example in EN 200 (dimension E), that provides an air gap disconnection. If this is the case, then backflow protection will be assumed to be adequate, and no further testing/verification will be needed.

This document specifies the evaluation of the fire performance of water mist systems used for local application involving flammable liquid fires.

b) flammable liquid channel fires in channels not exceeding the maximum specified width of the water mist system and with no limited channel length;
c) partially obstructed flammable liquid pool fires where the percentage of obstructed surface is limited to that tested;
d) spray fires up to 6 MW fuelled by flammable liquids;
e) spray and pool fire combinations where confined to a bunded area;
f) flammable liquid residues (ink and paper dust) on printing presses.

This document specifies fire testing requirements for water mist systems using wall mounted, electronically operated targeting nozzles for fire protection of domestic and residential occupancies up to a maximum ceiling height of 7,3 m.

Method C is suitable for soft asphalt with bitumen of kinematic viscosity at 60 °C of 4 000 mm2/s or less.
These methods can be used to evaluate the effect of water on asphalt mixtures with or without anti-stripping additives including liquids, such as amines; and fillers, such as hydrated lime or cement.
