Foreword
This document (CEN/TR 15441:2006) has been prepared by Technical Committee CEN/TC 343 “Solid
recovered fuels”, the secretariat of which is held by SFS.
This informative Technical Report was prepared by CEN/TC 343 Solid recovered fuel, working group 3 –
Sampling, sample reduction and supplementary methods. It was produced under the Mandate M/325 to CEN
on solid recovered fuels to provide the European Commission with a report on aspects of occupational safety
and health regarding the different stages of SRF production and use in order to decide whether there is a
need to develop a referring standard.
Introduction
Production, handling, storage, trade, sampling or analysis of SRF can be accompanied with certain health
risks, not only by hazardous chemical products, but by biological agents, too. In addition, the risk of
concomitance of hazardous waste in the input material cannot be excluded. These risks will be described in
this Technical Report.
The safety data sheet (SDS) for chemical products due to ISO 11014-1 is a means of transferring essential
hazard information (including information on transport, handling, storage and emergency actions) from the
supplier of a chemical product to the recipient of this product. For non-hazardous substances or products
there is a gap in information duties. Solid recovered fuels are derived from non-hazardous types of waste, so
prima facie there seems to be no need for preparing a SDS for SRF. In addition, the SDS due to ISO 11014-1
would not cover environmental or health risks in the stage of SRF production.
1 Scope
This Technical Report considers aspects of occupational safety and health within the scope of CEN/TC 343:
production and trade of solid recovered fuels.

4 Health risk factors
4.1 Exposure to health risk factors
Employees have contact to SRF and its components at different workplaces. Therefore, there may be an
exposure to biological agents, chemical substances or other health risk factors like heavy metals, dust or fire
risk, see Table 1.

4.2 Biological agents
4.2.1 Definition and description
4.2.1.1 General
Biological agents, in the meaning of Directive 2000/54/EC on the protection of workers from risks related to
exposure to biological agents at work, include mainly micro-organisms like bacteria, fungi (yeasts, molds) and
viruses, and also, genetically modified micro-organisms (GMO), cell cultures and human endoparasites which
may be able to provoke any infection, allergy or toxicity. As several microbial metabolic and degradation
products are able to cause such reactions in man, they are covered by the defintion of “biological agent”, too.
With regard to a potential exposure at working places in the SRF life-cycle, the following biological agents are
of special interest:
bacteria;
fungi;
microbial metabolic and destruction products:
endotoxins;
glucans;
mycotoxins;
microbial volatile organic compounds (MVOC).
4.2.1.2 Bacteria
Bacteria do not have a real nucleus with a nucleus membrane and chromosomes, therefore they are called
“procaryotes”. Their cells are mainly formed as balls or straight, curved or curled rods, with a width less than
1 µm and a length of 1 µm to 5 µm. Due to their behaviour in a special staining procedure, they are
distinguished into Gram-negative and Gram-positive bacteria. Under optimum living conditions, bacteria can
multiply very rapidly by cell division. Some bacteria form endospores to resist adverse environmental
conditions like UV radiation, heat, dryness and chemical disinfectants. The very small cells of actinomycetes
(0,5 µm to 1,5 µm long, Gram-positive, rod-shaped bacteria that form long threads) are also called “spores”.
4.2.1.3 Fungi
In contrast to bacteria, fungi have real nuclei and chromosomes and therefore belong to the “Eucaryotes”
group. Fungal cells form threads (molds) or chains of bubbles (yeasts) up to 10 µm in diameter. Fungal
threads (“hyphae”) form a weave (“mycelium”), which builds up spore carriers (“conidiophores”). These
carriers release the 2 µm to 8 µm small asexual fungal spores (“conidia”), which are spread by the air.
4.2.1.4 Microbial metabolic and destruction products
Several microbial metabolic and destruction products are capable of causing an allergic or toxic effect in
exposed people, see Table 2.
Table 2 — Health related microbial metabolic and destruction products
Substances Description
Endotoxins Endotoxins are part of the outer membrane of the cell wall of Gram-negative bacteria.
Endotoxins are invariably associated with Gram-negative bacteria whether the
organisms are pathogens or not. Although the term "endotoxin" is occasionally used to
refer to any cell-associated bacterial toxin, it is properly reserved to refer to the
lipopolysaccharide complex associated with the outer membrane of Gram-negative
bacteria such as E. coli, Salmonella, Shigella, Pseudomonas, Neisseria, Haemophilus,
and other leading pathogens. Endotoxins remain associated with the cell wall until
disintegration of the bacteria.
Glucans (1Æ3)-β-D-glucan is a polyglucose compound in the cell wall of fungi and some plants
and bacteria, which is released during disintegration of the cells.
Mycotoxins Some fungi produce mycotoxins which have a high toxicity to humans, like Aflatoxin
produced by Aspergillus flavus or Ochratoxin produced by Aspergillus and Penicillium
species.
Microbial Some micro-organisms produce microbial volatile organic compounds (MVOC). Up to
volatile now, about 30 MVOC produced by molds have been identified. The most important are
organic dimetyldisulfid, isobutanol, 1-octen-3-ol, 3-methyl-1-butanol, 3-methylfuran and 3-
compounds octanone. Bacteria and actinomycetes, too, produce MVOC, especially dimethyldisulfid
(MVOC) and isoprene.
4.2.2 Health effects
Biological agents can cause different harmful effects on human health, especially infections. Other effects are
toxic reactions, allergy and sensitization. Details are given in Annex A.
Depending on the level of risk of infection, biological agents are classified in four risk groups (Directive
2000/54/EC), see Table 3. Immunologic deficiencies, pregnancy or lactation are not considered.
NOTE SRF are produced from non-hazardous waste, which normally do not contain micro-organisms of risk group 3
or 4
