Introduction
This standard has been produced to assist designers, manufacturers and other interested bodies to interpret
the essential safety requirements in order to achieve conformity with European Legislation on machinery
safety.
This is one of a programme of standards produced by CEN/CENELEC under mandates from CEC and EFTA.
This programme has been divided into several categories to avoid duplication and to develop a logic which will
enable rapid production of standards and easy cross reference between them.
The hierarchy of standards is as follows:
a) Type A standards (generic safety standards) giving basic concepts, principles for design, and general
aspects that can be applied to all machinery;
b) Type B standards (group safety standards) dealing with one safety aspect or one type of safety related
device that can be used across a wide range of machinery:
 Type B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise,
etc.);
 Type B2 standards are safety related devices (e.g. two hand controls, interlocking devices, pressure
sensitive devices etc.);
c) Type C standards (machine safety standards) giving detailed safety requirements for a particular
machine or group of machines defined in the scope of the standard.
This is a type B1 standard and its primary purpose is to give guidance to the writers of type C standards when
machines are identified as having hazardous substances as a significant risk. This standard may also be used
as guidance in controlling the risk where there is no type C standard for a particular machine.
1 Scope
This European Standard deals with principles for the control of risks to health due to hazardous substances
from machinery. This European Standard is not applicable to hazardous substances which are a hazard to
health solely because of explosive, flammable, high or low temperature, high or low pressure or radioactive
properties.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to
apply to this European Standard only when incorporated in it by amendment or revision. For undated
references the latest edition of the publication referred to applies.
EN 292-1, Safety of machinery, basic concepts, general principles for design — Part 1: Basic terminology,
methodology.
EN 292-2, Safety of machinery, basic concepts, general principles for design — Part 2: Technical principles
and specifications.

3 Definitions
For the purposes of this standard, the following definitions apply:
3.1
intended use
see EN 292-1
3.2
hazardous substances
any chemical or biological agent which is hazardous to health, e.g. substances or preparations classified
1)
as .
 Very toxic;
 Toxic;
 Harmful;
 Corrosive;
 Irritant;
 Sensitising;
 Carcinogenic;
 Mutagenic;
 Teratogenic;
 Pathogenic;
 Asphyxiants;
4 Risk assessment
4.1 An identification of hazards and assessment of the foreseeable risks from substances hazardous to
health shall be made by the machinery manufacturer. This shall cover, as far as it is possible, any potential
personal exposures arising from the machine at any stage in its life.
NOTE Details of the methodology of the risk assessment are given in EN 292-1.
4.2 The level of risk depends on the hazardous properties of the substances, the likelihood that personal
exposure will occur and the degree of exposure. The health effects of hazardous substances may be:
 Short or long term;

 Reversible or irreversible.
4.3 Hazardous substances can be in any physical state (gases, liquids, solids) and can affect the body by:
 Inhalation;
 Ingestion;
 Contact with the skin, eyes and mucous membranes;
 Penetration through the skin.
4.4 The hazardous substances may arise from:
 Any part of a machine;
 Substances present in the machine;
 Material arising directly or indirectly from articles and/or substances processed by the machine or used on
the machine.
4.5 The stages in the life of a machine may include (see also EN 292-1):
 Construction;
 Transport and commissioning;
 Transport;
 Installation;
 Commissioning;
 Use;
 Operation, including starting up and shutting down;
 Failure;
 Setting or process changeover;
 Cleaning;
 Adjustment;
 Maintenance and repair;
 De-commissioning, dismantling and, as far as safety is concerned, disposal.

5 Types of emissions
5.1 Airborne emissions
5.1.1 Airborne emissions can be significant sources of exposure to hazardous substances. Inhalation is
usually the most significant of all the routes of entry (see 4.3). In addition, airborne emissions may enter the
body by the other routes particularly when substances are deposited on surfaces of the body or when they are
ingested.
5.1.2 Airborne emissions may arise from various sources including:
 Machining, e.g. sawing, grinding, sanding, milling;
 Evaporation and thermal convection e.g. open tanks, crucibles, solvent baths;
 Hot metal processes e.g. welding, brazing, soldering, profile cutting, casting;
 Material handling e.g. hopper charging, pneumatic conveying, sack filling;
 Spraying e.g. painting, high-pressure cleaning;
 Leaks e.g. at pump seals, flanges;
 By-products and effluents e.g. gases from drosses, rubber vulcanisation fumes;
 Maintenance e.g. emptying filter bags;
 Dismantling processes e.g. breaking lead batteries, stripping asbestos insulation;
 Combustion of fuel e.g. internal combustion engine exhausts;
 Apparatus for mixing food;
 Metal working e.g. nitrosamines from water soluble
