1 Scope
This document specifies methods for identifying fire hazards resulting from machinery
and for performing a risk assessment.
2 Normative references
The following documents are referred to in the text in such a way that some or all of
their content constitutes requirements of this document. For dated references, only the
edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
GB/T 15706-2012, Safety of machinery – General principles for design – Risk
assessment and risk reduction (ISO 12100.2010, IDT)
3 Terms and definitions
For the purpose of this document, terms and definitions given in ISO 12100 and ISO
13943 as well as the following apply.
4 Fire hazards
A fire hazard occurs if combustible materials (fuel), oxidizer (oxygen) and ignition
energy (heat) are available in sufficient quantities at the same place and at the same
time. A fire is an interaction of these three components in the form of an uninhibited
chemical reaction (see Figure 2).
5 Strategy for fire risk assessment and risk reduction
When deemed necessary, risk evaluation is followed by risk reduction.
In planning fire prevention and protection measures, normal operating conditions –
including startup and standstill procedures, possible technical failures and reasonably
foreseeable misuse – shall be taken into account.
Risk assessment shall include determination of the limits of the machinery, taking into
account the phases of the machinery life that can involve fire hazards.
6 Procedure for the selection of complementary protective measures
Determine the residual risk level based on the possible injury of persons (see Figure 4).
Annex B gives an example of a methodology for selecting and qualifying a fire
detection and fire suppression system.
Compare the performance of the fire prevention and protection system with the
requirements established in 6.1.2.If the risk of fire has not been adequately reduced,
repeat items 6.1.3 ~ 6.1.5.
7 Information for use
Comprehensive documentation that is readily understandable and unambiguous shall
be provided regarding.
Annex A
(Informative)
Examples of machines and their typical fire-related hazards
See Table A.1 for examples of machines and their typical fire-related hazards.
Annex B
(Informative)
Example of a methodology for selecting and qualifying a fire detection and fire
suppression system
The selection and qualifying of a fire detection and fire suppression system is a complex
procedure. Several considerations are needed to ensure a safe and reliable solution.
