and ii where appropriate, the prohibition of eating, drinking, smoking and the application of cosmetics in working areas where there is a risk of contamination by biological agents; and h where there are human patients or animals which are, or are suspected of being, infected with a Group 3 or 4 biological agent, the employer shall select the most suitable control and containment measures from those listed in Part II of Schedule 3 with a view to controlling adequately the risk of infection. 7 Without prejudice to the generality of paragraph (1), where there is exposure to a substance for which a maximum exposure limit has been approved, control of exposure shall, so far as the inhalation of that substance is concerned, only be treated as being adequate if the level of exposure is reduced so far as is reasonably practicable and in any case below the maximum exposure limit. 8 Without prejudice to the generality of paragraph (1), where there is exposure to a substance for which an occupational exposure standard has been approved, control of exposure shall, so far as the inhalation of that substance is concerned, only be treated as being adequate if– a that occupational exposure standard is not exceeded; or b where that occupational exposure standard is exceeded, the employer identifies the reasons for the standard being exceeded and takes appropriate action to remedy the situation as soon as is reasonably practicable. 9 Personal protective equipment provided by an employer in accordance with this regulation shall be suitable for the purpose and shall– a comply with any provision in the Personal Protective Equipment Regulations 2002 which is applicable to that item of personal protective equipment; or b in the case of respiratory protective equipment, where no provision referred to in sub-paragraph (a) applies, be of a type approved or shall conform to a standard approved, in either case, by the Executive. 10 Without prejudice to the provisions of this regulation, Schedule 3 shall have effect in relation to work with biological agents. 11 In this regulation, “adequate” means adequate having regard only to the nature of the substance and the nature and degree of exposure to substances hazardous to health. Use of control measures, etc. 8 1 Every employer who provides any control measure, other thing or facility in accordance with these Regulations shall take all reasonable steps to ensure that it is properly used or applied as the case may be. 2 Every employee shall make full and proper use of any control measure, other thing or facility provided in accordance with these Regulations and, where relevant, shall– a take all reasonable steps to ensure it is returned after use to any accommodation provided for it; and b if he discovers a defect therein, report it forthwith to his employer. Maintenance, examination and testing of control measures 9 1 Every employer who provides any control measure to meet the requirements of regulation 7 shall ensure that, where relevant, it is maintained in an efficient state, in efficient working order, in good repair and in a clean condition. 2 Where engineering controls are provided to meet the requirements of regulation 7, the employer shall ensure that thorough examination and testing of those controls is carried out– a in the case of local exhaust ventilation plant, at least once every fourteen months, or for local exhaust ventilation plant used in conjunction with a process specified in Column 1 of Schedule 4, at not more than the interval specified in the corresponding entry in Column 2 of that Schedule; or b in any other case, at suitable intervals. 3 Where respiratory protective equipment (other than disposable respiratory protective equipment) is provided to meet the requirements of regulation 7, the employer shall ensure that thorough examination and, where appropriate, testing of that equipment is carried out at suitable intervals. 4 Every employer shall keep a suitable record of the examinations and tests carried out in accordance with paragraphs (2) and (3) and of repairs carried out as a result of those examinations and tests, and that that record or a suitable summary thereof shall be kept available for at least five years from the date on which it was made. 5 Every employer shall ensure that personal protective equipment, including protective clothing, is– a properly stored in a well-defined place; b checked at suitable intervals; and c when discovered to be defective, repaired or replaced before further use. 6 Personal protective equipment which may be contaminated by a substance hazardous to health shall be removed on leaving the working area and kept apart from uncontaminated clothing and equipment. 7 The employer shall ensure that the equipment referred to in paragraph (6) is subsequently decontaminated and cleaned or, if necessary, destroyed. Monitoring exposure at the workplace 10 1 Where the risk assessment indicates that– a it is requisite for ensuring the maintenance of adequate control of the exposure of employees to substances hazardous to health; or b it is otherwise requisite for protecting the health of employees, the employer shall ensure that the exposure of employees to substances hazardous to health is monitored in accordance with a suitable procedure. 2 Paragraph (1) shall not apply where the employer is able to demonstrate by another method of evaluation that the requirements of regulation 7(1) have been complied with. 3 The monitoring referred to in paragraph (1) shall take place– a at regular intervals; and b when any change occurs which may affect that exposure. 4 Where a substance or process is specified in Column 1 of Schedule 5, monitoring shall be carried out at least at the frequency specified in the corresponding entry in Column 2 of that Schedule. 5 The employer shall ensure that a suitable record of monitoring carried out for the purpose of this regulation is made and maintained and that that record or a suitable summary thereof is kept available– a where the record is representative of the personal exposures of identifiable employees, for at least 40 years; or b in any other case, for at least five years, from the date of the last entry made in it. 6 Where an employee is required by regulation 11 to be under health surveillance, an individual record of any monitoring carried out in accordance with this regulation shall be made, maintained and kept in respect of that employee. 7 The employer shall– a on reasonable notice being given, allow an employee access to his personal monitoring record; b provide the Executive with copies of such monitoring records as the Executive may require; and c if he ceases to trade, notify forthwith the Executive thereof in writing and make available to the Executive all monitoring records kept by him. Health surveillance 11 1 Where it is appropriate for the protection of the health of his employees who are, or are liable to be, exposed to a substance hazardous to health, the employer shall ensure that such employees are under suitable health surveillance. 2 Health surveillance shall be treated as being appropriate where– a the employee is exposed to one of the substances specified in Column 1 of Schedule 6 and is engaged in a process specified in Column 2 of that Schedule, and there is a reasonable likelihood that an identifiable disease or adverse health effect will result from that exposure; or b the exposure of the employee to a substance hazardous to health is such that– i an identifiable disease or adverse health effect may be related to the exposure; ii there is a reasonable likelihood that the disease or effect may occur under the particular conditions of his work; and iii there are valid techniques for detecting indications of the disease or effect, and the technique of investigation is of no or low risk to the employee. 3 The employer shall ensure that a health record, containing particulars approved by the Executive, in respect of each of his employees to whom paragraph (1) applies, is made and maintained and that that record 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 employer shall– a on reasonable notice being given, allow an employee access to his personal health record; b provide the Executive with copies of such health records as the Executive may require; and c if he ceases to trade, notify the Executive forthwith in writing and make available to the Executive all health records kept by him. 5 If an employee is exposed to a substance specified in Schedule 6 and is engaged in a process specified therein, the health surveillance required under paragraph (1) shall include medical surveillance under the supervision of a relevant doctor at intervals of not more than twelve months or at such shorter intervals as the relevant doctor may require. 6 Where an employee is subject to medical surveillance in accordance with paragraph (5) and a relevant doctor has certified by an entry in the health record of that employee that in his professional opinion that employee should not be engaged in work which exposes him to that substance or that he should only be so engaged under conditions specified in the record, the employer shall not permit the employee to be engaged in such work except in accordance with the conditions, if any, specified in the health record, unless that entry has been cancelled by a relevant doctor. 7 Where an employee is subject to medical surveillance in accordance with paragraph (5) and a relevant doctor has certified by an entry in his health record that medical surveillance should be continued after his exposure to that substance has ceased, the employer shall ensure that the medical surveillance of that employee is continued in accordance with that entry while he is employed by the employer, unless that entry has been cancelled by a relevant doctor. 8 An employee to whom this regulation applies shall, when required by his employer and at the cost of the employer, present himself during his working hours for such health surveillance procedures as may be required for the purposes of paragraph (1) and, in the case of an employee who is subject to medical surveillance in accordance with paragraph (5), shall furnish the relevant doctor with such information concerning his health as the relevant doctor may reasonably require. 9 Where, as a result of health surveillance, an employee is found to have an identifiable disease or adverse health effect which is considered by a relevant doctor or other occupational health professional to be the result of exposure to a substance hazardous to health the employer of that employee shall– a ensure that a suitably qualified person informs the employee accordingly and provides the employee with information and advice regarding further health surveillance; b review the risk assessment; c review any measure taken to comply with regulation 7, taking into account any advice given by a relevant doctor, occupational health professional or by the Executive; d consider assigning the employee to alternative work where there is no risk of further exposure to that substance, taking into account any advice given by a relevant doctor or occupational health professional; and e provide for a review of the health of any other employee who has been similarly exposed, including a medical examination where such an examination is recommended by a relevant doctor, occupational health professional or by the Executive. 10 Where, for the purpose of carrying out his functions under these Regulations, a relevant doctor requires to inspect any workplace or any record kept for the purposes of these Regulations, the employer shall permit him to do so. 11 Where an employee or an employer is aggrieved by a decision recorded in the health record by a relevant doctor to suspend an employee from work which exposes him to a substance hazardous to health (or to impose conditions on such work), he may, by an application in writing to the Executive within 28 days of the date on which he was notified of the decision, apply for that decision to be reviewed in accordance with a procedure approved for the purposes of this paragraph by the Department of Enterprise, Trade and Investment, and the result of that review shall be notified to the employee and employer and entered in the health record in accordance with the approved procedure. Information, instruction and training for persons who may be exposed to substances hazardous to health 12 1 Every employer who undertakes work which is liable to expose an employee to a substance hazardous to health shall provide that employee with suitable and sufficient information, instruction and training. 2 Without prejudice to the generality of paragraph (1), the information, instruction and training provided under that paragraph shall include– a details of the substances hazardous to health to which the employee is liable to be exposed including– i the names of those substances and the risk which they present to health; ii any relevant occupational exposure standard, maximum exposure limit or similar occupational exposure limit; iii access to any relevant safety data sheet; and iv other legislative provisions which concern the hazardous properties of those substances; b the significant findings of the risk assessment; c the appropriate precautions and actions to be taken by the employee in order to safeguard himself and other employees at the workplace; d the results of any monitoring of exposure in accordance with regulation 10 and, in particular, in the case of a substance hazardous to health for which a maximum exposure limit has been approved, the employee or his representatives shall be informed forthwith, if the results of such monitoring show that the maximum exposure limit has been exceeded; e the collective results of any health surveillance undertaken in accordance with regulation 11 in a form calculated to prevent those results from being identified as relating to a particular person; and f where employees are working with a Group 4 biological agent or material that may contain such an agent, the provision of written instructions and, if appropriate, the display of notices which outline the procedures for handling such an agent or material. 3 The information, instruction and training required by paragraph (1) shall be– a adapted to take account of significant changes in the type of work carried out or methods of work used by the employer; and b provided in a manner appropriate to the level, type and duration of exposure identified by the risk assessment. 4 Every employer shall ensure that any person (whether or not his employee) who carries out work in connection with the employer’s duties under these Regulations has suitable and sufficient information, instruction and training. 5 Where containers and pipes for substances hazardous to health used at work are not marked in accordance with any relevant legislation listed in Schedule 7, the employer shall, without prejudice to any derogations provided for in that legislation, ensure that the contents of those containers and pipes, together with the nature of those contents and any associated hazards, are clearly identifiable.
