AS/NZS 4024.1:2006 Series

Terminology - General

Provides a set of terms and definitions for use within other safety of machinery Standards and during discussions relating to machinery safety.

Basic terminology and methodology

Specifies the basic terminology and methodology to be used by designers in achieving safety of machinery.

Technical principles

Defines the technical principles required to achieve safety in the design of machinery. Does not deal with injury to domestic animals, property or the environment.

Principles of risk assessment

Specifies principles for the procedure of risk assessment by which the knowledge and experience of the harm related to machinery is gathered together to aid in assessing risks during all phases in the life of machinery. Guidance on the information necessary to allow risk assessments to be carried out is provided, as is a brief outline of some of the techniques available.

Reduction of risks to health and safety from hazardous substances emitted by machinery - Principles and specification for machinery manufacturers

Provides principles for controlling risks to health resulting from the emission of hazardous substances from machinery.

Design principles - Terminology and general principles

Specifies the ergonomic design principles and terminology to be followed by designers during the process of designing work equipment, so as to achieve safety of machinery.

General principles

Provides safety requirements and guidance on the principles to be used in the design of the safety related parts of machinery control systems. Categories are specified and the characteristics of the safety functions are described.

Validation

Specifies the conditions and procedures to be followed for the validation by both analysis and testing of safety functions provided and category achieved by the safety related parts of control systems using the design rationale provided by the designer. When validating programmable electronic systems, this Standard does not provide complete requirements and can require the use of other Standards such as the AS 61508 series.

Guards - General requirements for the design and construction of fixed and moveable guards

Specifies requirements for the design and construction of fixed and movable guards intended to afford protection from mechanical hazards at machinery.

Principles for design and selection

Specifies principles for the design and selection of interlocking devices associated with guards. The principles are independent of the energy sources used on the machine.

Prevention of unexpected start-up

Specifies means incorporated at the design stage intended to prevent an unexpected machine start-up. The means include energy isolation and dissipation. Applies to all forms of energy source including those external to the machine, such as wind, gravity and electro-magnetic.

Emergency stop - Principles for design

Specifies functional requirements and the principles of design for the emergency stop of machinery without regard to the energy source used to control the functions. It does not apply to hand guided machines, hand held portable machines or to machines where the provision of an emergency stop would not reduce the level of risk to operator or other person.

Basic human body measurements for technological design

Provides information and descriptions of anthropometric measurements as the basis for comparing population groups for ergonomists and others involved in the geometric design of places where people work.

Principles for determining the dimensions required for openings for whole body access to machinery

Specifies the minimum opening dimensions required to gain whole body access to machinery. The dimensions are more applicable to non-mobile machinery as there may be additional specific requirements for mobile machinery.

Principles for determining the dimensions required for access openings

Specifies minimum dimensions for access openings in machinery. Values for additional space requirements are provided. Applies primarily to non-mobile machinery, as there may be additional specific requirements for mobile machinery.

Anthropometric data

Specifies requirements for human body measurements required for calculating the dimensions of access openings in machinery.

Safety distances to prevent danger zones being reached by the upper limbs

Specifies the minimum safety distances from a barrier to the danger zone of a machine to prevent the danger zone being reached by the upper limbs of a person of age 3 years and above. The Standard is applicable only where safety can be assured by distance alone. The Standard will not provide sufficient protection against radiation or substances emitted from the machine.

Safety distances to prevent danger zones being reached by the lower limbs

Establishes values for safety distances to prevent access and to impede free access to danger zones of machinery, to prevent their being reached by the lower limbs of persons of 14 years and older. The distances apply where safety can be assured by distance alone and access by the upper limbs is not foreseeable by the risk assessment.

Minimum gaps to prevent crushing of parts of the human body

Establishes values for the minimum gaps relative to parts of the human body to prevent risk of crushing between two surfaces, at least one of which can move.

General principles for human interaction with displays and control actuators

Specifies general principles to be followed when designing displays and control actuators on machinery to minimize errors on the part of the operator and to ensure an efficient interaction between the operator and equipment.

Displays

Specifies the ergonomic requirements for visual, audible and tactile displays for use in machinery. It provides guidance on the selection, design and location of displays to avoid potential ergonomic hazards associated with the use of displays.

Control actuators

Provides guidance for the design, selection and location of manual control actuators so they are adapted to operator needs, are suitable for the control task in question and take into account the circumstances of their use.

Requirements for visual, auditory and tactile signs

Specifies requirements for visual, auditory and tactile methods of indicating safety related information. It sets out a system of colours, signs, marking and other means of indicating hazards and meeting emergencies. In addition, it sets out ways of coding visual, auditory and tactile signals to enable safe use and monitoring of machinery.

Requirements for marking

Specifies the requirements for marking machinery. Provides general rules on marking for identification, safe use in respect of mechanical and electrical hazards and in preventing the hazards arising from incorrect connections.

Requirements for the location and operation of actuators

Specifies the safety related requirements for actuators operated by hand or other parts of the human body at the man-machine interface. It applies to both single actuators, and groups of actuators.

System of auditory and visual danger and information signals

Specifies a series of both visual and auditory danger and information signals which take into account the level of urgency for the given circumstances. The Standard applies to danger and information signals that have to be perceived and recognized from each other. The Standard does not apply to fields covered by specific Standards or conventions, e.g. fire alarms, public transport or navigation signals.
