International Labour Conference – 113th Session, Geneva, 2025
Recommendation No. 209
Recommendation concerning prevention and protection against biological hazards in the working environment
(13 June 2025)
The General Conference of the International Labour Organization,
Having been convened in Geneva by the Governing Body of the International Labour Office, and having met at its 113th Session on 2 June 2025,
Having decided upon the adoption of certain proposals with regard to protection against biological hazards in the working environment, which is the fourth item on the agenda of the session,
Having determined that these proposals shall take the form of a Recommendation supplementing the Biological Hazards in the Working Environment Convention, 2025,
adopts this 13 June 2025 the following Recommendation, which may be cited as the Biological Hazards in the Working Environment Recommendation, 2025:
1. The provisions of this Recommendation supplement those of the Biological Hazards in the Working Environment Convention, 2025 (“the Convention”), and should be considered in conjunction with them.
I. Definitions and scope
2. With reference to the definition contained in Article 1(a) of the Convention, biological hazards include:
(a) pathogenic microorganisms and their associated toxins and allergens, including certain protozoa, bacteria, fungi, oomycetes and algae;
(b) cells and cell cultures, including both primary cultures and immortalized cell lines, that may be contaminated with other biological hazards or carry inherent risks such as tumour- inducing potential, toxins or allergens;
(c) endoparasites, namely protozoa and helminths;
(d) non-cellular microbiological entities, including viruses, prions and recombinant, genetically modified or synthetic DNA and RNA materials;
(e) irritants, allergens and toxins of animal or plant origin, including any venom or allergen- containing secretions produced by animals or plants, with the exception of pollen, that may cause irritation, allergic reactions or systemic toxicity upon exposure via bites, stings or any other event resulting in the release or presence of these substances.
3. Harm to human health caused by exposure to biological hazards in the working environment includes:
(a) infectious diseases such as brucellosis, viral hepatitis, human immunodeficiency virus disease, tetanus, tuberculosis, anthrax and leptospirosis, including health effects secondary to acute or chronic infection, such as liver disease secondary to viral hepatitis, and their sequelae;
(b) non-infectious diseases such as toxic or inflammatory syndromes associated with bacterial
or fungal allergens or toxins;
(c) death or any personal injury or disease resulting from an occupational accident involving exposure to a biological hazard in the working environment.
4. Health not only indicates the absence of disease or infirmity but also includes the physical and mental elements affecting health which are directly related to safety and health at work.
5. The modes of transmission mentioned in Article 1(b) of the Convention include:
(a) transmission through the air, which involves the biological hazards travelling through or being suspended in the air;
(b) direct transmission, which involves living organisms, including humans and animals, that transmit a biological hazard through direct contact;
(c) indirect transmission, which occurs via vectors and other transmitters such as water, food, organic materials, bodily fluids or fomites.
6. The routes of exposure mentioned in Article 1(b) of the Convention include inhalation, ingestion, percutaneous injury and eye, skin and mucous membrane absorption or adsorption. These routes are usually dependent upon the characteristics of the biological hazard and the working environment.
7. To the greatest extent possible, the provisions of the Convention and this Recommendation should be applied to all branches of economic activity and to all categories of workers. Provision could be made for such measures as may be necessary and practicable to give self-employed persons protection analogous to that provided for in the Convention and this Recommendation.
II. Preventive and protective measures
8. Members should take measures, in accordance with national law and practice, with a view to ensuring that those who design, manufacture, import, provide or transfer biological substances, agents or products to which workers could be exposed in the course of their work:
(a) satisfy themselves that, so far as is reasonably practicable, such substances, agents or products do not entail dangers for the safety and health of those using them correctly;
(b) make available information concerning the correct use and hazardous properties of such substances, agents or products, including in the form of safety and health information sheets if such are available, as well as instructions on preventing known risks;
(c) undertake studies and research or otherwise keep abreast of the scientific and technical knowledge necessary to comply with clauses (a) and (b);
(d) take into consideration the United Nations Recommendations on the Transport of Dangerous Goods, the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal, the Cartagena Protocol on Biosafety to the Convention on Biological Diversity, the Convention on the Prohibition of the Development, Production and Stockpiling of Bacteriological (Biological) and Toxin Weapons and on their Destruction, the International Health Regulations or any other relevant and applicable convention or instrument.
9. The national arrangements and guidelines referred to in Article 7(1) of the Convention should:
(a) contain provisions on:
(i) carrying out a risk assessment and regularly reviewing it;
(ii) preventive and protective measures following the hierarchy of controls;
(iii) hygiene;
(iv) information and training of workers;
(v) consultation and participation of workers and their representatives for the matters under (i) to (iv);
(b) address, as appropriate, infection prevention and control measures, risk-based biosecurity and biosafety control measures such as levels of containment in laboratories, ventilation, vector control, decontamination and disinfection procedures, as well as risk-based
procedures for handling and disposing of hazardous waste;
(c) consider uncertainties regarding the presence of biological hazards in living organisms, vectors or other potential transmitters;
(d) be adequate and proportionate to the level of risk of exposure in each sector or occupation and to the hazards identified and risks assessed by the competent authorities.
10. The sectors and occupations referred to in Article 7(2)(c)(i) of the Convention to be included in an evaluation of risks could include, but not be limited to:
(a) the healthcare sector;
(b) food production and agricultural work, including in the animal, vegetable and grain sectors;
(c) the water and waste management sector;
(d) cleaning and maintenance work;
(e) humanitarian work;
(f) laboratory work;
(g) the biotechnology and pharmaceutical sectors;
(h) funeral services and mortuary work;
(i) the construction sector;
(j) the forestry sector;
(k) the transport sector;
(l) occupations that are critical to the functioning of society and its well-being during public health emergencies, as determined by an evaluation of biological risks by the competent authorities.
11. The workers referred to in Article 7(2)(c)(ii) of the Convention should include:
(a) pregnant and breastfeeding women;
(b) young workers;
(c) older workers;
(d) workers with disabilities;
