Labour Protection Requirements when coming into Contact with Biological SubstancesIssued pursuant to I. General Provisions1. This Regulation prescribes requirements for the protection of employees against the risk to their safety and health (hereinafter - risk) which is caused or may be caused when coming into contact with biological substances in the workplace. 2. Biological substances are biological agents - micro-organisms (unicellular or non-cellular organisms capable of replication or of transferring genetic material), including genetically modified micro-organisms, cell cultures (cells grown in laboratory conditions originated from multi-cellular organism) and human endoparasites, which may be agents of an infectious disease or which may cause an infestation, allergy or toxicity (hereinafter - health impairment) or due to which a person may become a carrier of a disease causing agent (hereinafter - biological agents). 3. This Regulation shall not apply to the protection of employees against the risk that is caused or may be caused when coming into contact with ectoparasites, insects, biological material of animal origin, plant allergens and toxins. 4. Biological agents shall be classified into four risk groups taking into account their ability to cause health impairments: 4.1. group 1 biological agent - biological agent unlikely to cause health impairments and against the effect of which effective prophylactic measures and medical treatment are possible; 4.2. group 2 biological agent - biological agent, which may cause health impairments and may be dangerous to employees, but the possibility that it may present a threat to other people is small. Effective prophylactic measures and medical treatment are possible against the effect thereof; 4.3. group 3 biological agent - biological agent, which may cause severe health impairment (health impairment proceeding with explicit subjective deterioration of health and objectively determined explicit distortions of organism functions endangering life) and is dangerous to employees. There is a risk that it may present a threat to other people. Effective prophylactic measures and medical treatment are possible against the effect thereof; 4.4. group 4 biological agent - biological agent, which may cause a severe health impairment and is dangerous to employees. There is a high risk that it may present a threat to other people. Effective prophylactic measures and medical treatment are not possible. 5. If when classifying biological agents there are doubts in which risk group the biological agent is to be included, it shall be included in a group of the highest risk level. 6. If biological agents are not to be included in groups 2, 3 or 4 according to their classification (Annex 1), it shall not mean that they belong to group 1. Such biological agents shall be included in group 1 in case if there is evidence that a biological agent is unlikely to cause health impairments to a person and there are effective prophylactic measures and medical treatment against the effect thereof. 7. All viruses that have already been isolated in the human organism but have not been assessed and not referred to in Annex 1 of this Regulation shall be deemed to be at least group 2 biological agents, except cases where there is evidence that the relevant viruses are unlikely to cause impairments of human health. 8. The employer shall be responsible for compliance with this Regulation. 9. Compliance with this Regulation shall be controlled by the State Labour Inspectorate, but certain control functions shall be performed by the State Environmental Service and the Health Inspectorate (hereinafter - the supervisory and control authorities) in accordance with the by-laws thereof. [28 April 2008] II. Risk Assessment10. In accordance with the procedures determined in laws and regulations, employers shall ensure risk assessment within the scope of internal supervision of the work environment and a risk assessment system of the work environment of an undertaking. 11. If in performing the inspection of workplaces it is determined that biological agents cause or may cause a risk, they shall be assessed determining the type, level and duration of exposure to biological agents. 12. If the work is connected with several biological agents, the risk shall be assessed considering all biological agents used at work. 13. Risk shall be assessed not less than once a year, as well as if changes in the work environment have occurred that may affect the safety and health of employees. 14. In performing risk assessment, the following shall be taken into account: 14.1. classification of biological agents; 14.2. recommendations of the supervisory and control authorities regarding the control of biological agents in order to ensure the health protection of an employee if the employee is or may be subject to exposure to biological agents during the work process; 14.3. information on diseases, which may be contracted by employees while performing work duties; 14.4. potential allergic and toxic effects, which may occur in performing work duties; 14.5. information on occupational diseases determined to employees and diseases related to work; 14.6. intensified biological agent impact on the employees whose susceptibility to diseases may be affected by a disease suffered earlier, use of medical products, immunosystem deficiency, pregnancy or breast-feeding, and similar. 15. Upon a request of the supervisory and control authorities employers shall provide information regarding risk assessment in the undertaking. III. Prevention and Reduction of Risk16. If possible, employers shall not utilise the biological agents referred to in Annex 1 of this Regulation in the work process, but they shall replace them with such biological agents as are not dangerous or, in accordance with scientific findings, are less dangerous to the health of employees. 17. On the basis of the results of the risk assessment and the information obtained during inspection of workplaces, an employer shall determine: 17.1. workplaces at which employees are or may be subject to the impact of biological agents; 17.2. employees who are or may be subject to the impact of biological agents; 17.3. measures performed to prevent or reduce the risk caused by biological agents. 18. If during risk assessment it is determined that there is a risk to the safety and health of employees, the employer has an obligation to eliminate it, but if it is not technically possible to do so taking account the specific nature of particular work, the employer shall reduce the risk to a minimum taking the following measures: 18.1. limiting the number of employees who are or may be subject to exposure to biological agents at their workplaces; 18.2. organising working procedures and control thereof so as to prevent or reduce to a minimum the release of biological agents into the work environment; 18.3. taking collective protection measures or if it is not possible to prevent the impact of biological agents on employees by utilising other means, providing employees with personal protective equipment; 18.4. ensuring compliance with the hygiene and epidemic safety regime at workplaces in order to prevent or reduce the possibility of accidental transmission or release of biological agents; 18.5. installing, in accordance with the requirements on the use of safety signs at workplaces determined in laws and regulations, biohazard signs and other safety signs at workplaces where coming into contact with biological agents is possible; 18.6. developing an evacuation plan and an action plan for employees in cases of unforeseen high pollution and other emergency situations related to exposure to biological agents; 18.7. if necessary and technically possible, utilising appropriate regular or continuous control methods for the detection of biological agents in the work environment in order to determine in sufficient time the release thereof (for example, release of biological agents into the environment, escape out of containers and technological equipment); 18.8. in accordance with the procedures determined in laws and regulations ensuring fast and safe collection, storage and disposal of waste containing biological agents using sealed, specially labelled containers made of appropriate material on which the contents thereof has been indicated; 18.9. ensuring safe storage, transport and reloading of biological agents at a workplace; 18.10. entering into a contract for taking, processing and testing of tissue samples of humans or animals with a testing laboratory which has been accredited in the Latvian National Accreditation Bureau of sabiedrība ar ierobežotu atbildību "Standartizācijas, akreditācijas un metroloģijas centrs" [the limited liability company Standardization, Accreditation and Metrology Centre] in accordance with the standard LVS EN ISO/IEC 17025:2005 "General requirements for the competence of testing and calibration laboratories", and in respect of which the Ministry of Economics has published a notification in the official gazette Latvijas Vēstnesis. [28 April 2008] 19. If employees work with biological agents which endanger the safety and health of employees at the workplace, the employer shall ensure the following: 19.1. employees shall not drink, eat and smoke in the risk area; 19.2. appropriate washing and toilet facilities equipped with eye washes and skin antiseptics; 19.3. provision of employees with protective clothing and other necessary individual protective equipment in accordance with the procedures determined in laws and regulations; 19.4. storage of work protective clothing separately from the personal clothing of employees and washing of work protective clothing in appropriate equipment separately from other clothing; 19.5. work protective clothing and other personal protective equipment shall not be taken out of the territory of the undertaking; 19.6. storage of individual protective equipment in a place particularly provided for this purpose, regular checking and cleaning thereof, timely repair or replacement with new devices of defective and worn devices. 20.

Annex 1 Classification of Groups 2, 3 and 4 Biological Agents[24 November 2020]
Viruses
Agents of prion diseases
Parasites
Fungi
Notes and designations. 1. Classification includes biological agents which may cause health impairment to a human, and possible toxicity and allergenic effect thereof, availability of an effective vaccine have been indicated, and also the agents after exposure to which the list of employees subject to exposure thereof is to be kept for 10 years by designating them by letters have been specified: A - allergy possible; D - the list of such employees who have been subject to the exposure of such biological agent. The list shall be kept for 10 years after the end of the last known exposure; T - production of toxins; V - effective vaccine is available and registered. 2. If several species of the biological agent are known which are pathogenic to humans, the classification includes the species that cause health impairments most frequently and a general reference indicating the capability of other representatives of species of the same genus to affect the state of health. If the whole genus has been referred to in the list of biological agents, it means that species and strains known not to cause health impairments are not meant. 3. Such animal and plant disease-causing agents, which are known as not affecting humans have not been included in the classification, as well as genetically modified micro-organisms have not been considered. 4. Biological agents have been classified in compliance with the taxonomy and nomenclature laid down in the latest international agreements in force at the time of the preparation of this list. 5. Group 3 biological agents marked with two asterisks (**) in the list may only cause a minor risk of infection to employees because usually it is not possible to become infected with them by inhalation. 6. The indication "spp." on the biological agents referred to in this list means other species which belong to the same genus and have not been included in this list separately but are known to cause diseases in humans. 7. Indications on the biological agent mean: a tick-borne encephalitis; b hepatitis D virus is pathogenic only to such employees who have become infected simultaneously or secondary with hepatitis B virus. Therefore the vaccination against hepatitis B virus will also protect employees not infected with this virus against the hepatitis D (Delta) virus; c for types A and B only; d recommended for work, which includes direct contact with these agents; e two viruses have been determined: one of them is the buffalopox type virus and the other - Vaccinia virus variety; f cowpox virus variety; g Vaccinia virus variety; h currently there is no evidence on human health impairments caused by retroviruses of monkey strains. It is recommended to apply the containment level 3 as a precaution measure when working with these viruses; i classification in accordance with the WHO Global Action Plan to minimize poliovirus facility-associated risk after type-specific eradication of wild polioviruses and sequential cessation of oral polio vaccine use.
