SCHEDULE 3 ADDITIONAL PROVISIONS RELATING TO WORK WITH BIOLOGICAL AGENTS
Regulations 2(1) and 7(6)(a) and (10)

PART I provisions of general application to biological agents

1 Interpretation
In this Schedule “diagnostic service” means any activity undertaken solely with the intention of analysing specimens or samples from a human patient or animal in which a biological agent is or is suspected of being present for purposes relating to the assessment of the clinical progress, or assistance in the clinical management, of that patient or animal.

2 Classification of biological agents
(1) Where a biological agent does not have an approved classification, the employer shall provisionally classify that agent in accordance with sub-paragraph (2), having regard to the nature of the agent and the properties of which he may reasonably be expected to be aware.
(2) When provisionally classifying a biological agent the employer shall assign that agent to one of the following Groups according to its level of risk of infection and, if in doubt as to which of two alternative Groups is the more appropriate, he shall assign it to the higher of the two–
(a) Group 1—unlikely to cause human disease;
(b) Group 2—can cause human disease and may be a hazard to employees; it is unlikely to spread to the community and there is usually effective prophylaxis or treatment available;
(c) Group 3—can cause severe human disease and may be a serious hazard to employees; it may spread to the community, but there is usually effective prophylaxis or treatment available;
(d) Group 4—causes severe human disease and is a serious hazard to employees; it is likely to spread to the community and there is usually no effective prophylaxis or treatment available.
(3) Where an employer is using a biological agent which has an approved classification and the risk of infection for that particular agent is different from that expected, the employer shall reclassify the agent in consultation with the Executive as if performing a provisional classification under sub-paragraph (2).

3 Special control measures for laboratories, animal rooms and industrial processes
(1) Every employer who is engaged in any of the activities specified in sub-paragraph (3) shall ensure that measures taken to control adequately the exposure of his employees to biological agents include, in particular, the most suitable combination of containment measures from those listed in Parts II and III as appropriate, taking into account–
(a) the nature of the activity specified in sub-paragraph (3);
(b) the minimum containment level specified in sub-paragraph (4);
(c) the risk assessment; and
(d) the nature of the biological agent concerned.
(2) An employer who is engaged in–
(a) any of the activities specified in sub-paragraph (3)(a) or (b) shall select measures from Part II;
(b) the activity specified in sub-paragraph (3)(c) shall select measures from Part III and, subject to sub-paragraph (4), when making that selection he may combine measures from different containment levels on the basis of a risk assessment related to any particular process or part of a process.
(3) The activities referred to in sub-paragraph (1) are–
(a) research, development, teaching or diagnostic work in laboratories which involves working with a Group 2, Group 3 or Group 4 biological agent or material containing such an agent;
(b) working with animals which have been deliberately infected with a Group 2, Group 3 or Group 4 biological agent or which are, or are suspected of being, naturally infected with such an agent; and
(c) industrial processes which involve working with a Group 2, Group 3 or Group 4 biological agent.
(4) Subject to sub-paragraph (5), the minimum containment level referred to in sub-paragraph (1) shall be–
(a) level 2 for activities which involve working with a Group 2 biological agent;
(b) level 3 for activities which involve working with a Group 3 biological agent;
(c) level 4 for activities which involve working with a Group 4 biological agent;
(d) level 2 for laboratories which do not intentionally propagate, concentrate or otherwise increase the risk of exposure to a biological agent but work with materials in respect of which it is unlikely that a Group 3 or Group 4 biological agent is present;
(e) level 3 or 4, where appropriate, for laboratories which do not intentionally propagate, concentrate or otherwise increase the risk of exposure to a Group 3 or Group 4 biological agent but where the employer knows, or it is likely, that such a containment level is necessary; and
(f) level 3 for activities where it has not been possible to carry out a conclusive assessment but where there is concern that the activity might involve a serious health risk for employees.
(5) The Executive may approve guidelines specifying the minimum containment measures which are to apply in any particular case.
(6) The Executive shall not approve any guidelines under paragraph (5) unless it is satisfied that the health of any person who is likely to be affected by the use of those guidelines will not be prejudiced.

4 List of employees exposed to certain biological agents
(1) Subject to sub-paragraph (2), every employer shall keep a list of employees exposed to a Group 3 or Group 4 biological agent, indicating the type of work done and, where known, the biological agent to which they have been exposed, and records of exposures, accidents and incidents, as appropriate.
(2) Sub-paragraph (1) shall not apply where the results of the risk assessment indicate that–
(a) the activity does not involve a deliberate intention to work with or use that biological agent; and
(b) there is no significant risk to the health of employees associated with that biological agent.
(3) The employer shall ensure that the list or a copy thereof is kept available in a suitable form for at least 40 years from the date of the last entry made in it.
(4) The relevant doctor referred to in regulation 11, and any employee of that employer with specific responsibility for the health and safety of his fellow employees, shall have access to the list.
(5) Each employee shall have access to the information on the list which relates to him personally.

(c) detail the measures which the employer must take to prevent or adequately control the exposure of his employees to substances hazardous to health (regulation 7);
(d) provide for further duties in respect of care and decontamination of personal protective equipment (regulation 9);
(e) provide for the keeping of an individual record of air monitoring where an employee is required to be under health surveillance (regulation 10);
(f) extend the duties on employers with respect to health surveillance where an employee is found to have an identifiable disease or adverse health effect caused by exposure to a substance hazardous to health (regulation 11);
(g) introduce a duty to ensure that the contents of containers and pipes for substances hazardous to health used at work are clearly identifiable (regulation 12(5));
