Functional Flowchart Not Applicable. Objective To provide a corporate standard that outlines SCL s procedure for managing the hazards associated with lead. Scope This corporate standard applies to any location or situation in which a SCL employee or controlled contractor may be exposed to a lead hazard. Definitions Atmospheric lead level: the concentration of lead in air expressed in milligrams per cubic metre (mg/m 3 ). Biological monitoring: means - for a hazardous substance testing for the presence of a hazardous substance, its metabolites or a biochemical change in a person s body tissue, exhaled air or fluid; or for lead testing for the presence of lead in a person s tissue or fluid; or testing for a biochemical change in a person s tissue or fluid. Blood lead level: the concentration of lead in whole blood expressed in micromoles per litre (µmol/l) or micrograms per decilitre (µg/dl). Competent person: a person who has through a combination of training, education and experience, acquired knowledge and skills enabling that person to perform correctly a specified task. Designated doctor: a doctor: who is registered as a specialist registrant in specialty of occupational medicine under the Medical Practitioners Registration Act 2002 ; or who has satisfactorily completed a health surveillance training program supplied by the chief executive. Exposure standard: means an airborne concentration of a particular substance in a person s breathing zone exposure to which, according to current knowledge, should not cause adverse health affects nor undue discomfort to nearly all workers, as established by the National Occupational Health and Safety Commission s (NOHSC s) Exposure Standards for Atmospheric Contaminants in the Occupational Environment. Hazardous substance: a substance which: is listed in the NOHSC s List of Designated Hazardous Substances; or meets the NOHSC approval criteria for classifying hazardous substances, or has been classified as a hazardous substance by the manufacturer or importer in accordance with the NOHSC. Health surveillance: the monitoring of individuals for the purpose of identifying changes in health status due to occupational exposure to a hazardous substance. It includes biological monitoring and medical examination but not workplace monitoring as defined below. HBIRDPRO_562504 20100908100837405.DOC Page: 2 of 19
Lead: means lead metal, inorganic lead compounds and lead salts of organic acids. Lead process: means any of the processes listed in Attachment 1, and includes any other process as determined by the Statutory Health and Safety Authority for a particular state / territory. Lead-containing paint: paint which contains lead or lead compounds in excess of 1.0% (w/w) of the dried film. Lead-risk job: any work activity / job, where the blood lead level of a person might reasonably be expected to rise, or does rise, above 1.45 µmol/l (30 µg/dl) or the removal level as set out in Table 1. Note: For the purpose of this corporate standard, if a Work Method Statement for a task / activity indicates a moderate risk or higher, then the task / activity is to be considered and treated as a lead-risk job. MSDS: Material Safety Data Sheet. Removal level: a confirmed blood lead level at which a person is to be transferred from a lead-risk job to a job that is not a lead-risk job. Return level: a confirmed blood lead level at which a person removed from a lead-risk job to a job that is not a lead-risk job, can be considered by an authorised doctor for return to a lead-risk job. Workplace Monitoring: to survey measures that are used to control lead in the workplace. This includes the measurement of atmospheric contaminants, but does not include biological monitoring which is an element of health surveillance. Responsibilities OH&S Systems Manager To maintain the currency and accuracy of the reflective of legislative and corporate change. Station / Site Manager To monitor the implementation of the and allocate responsibilities and resources to ensure site-specific practices/procedures are developed to satisfy the. Workers To comply at all times with the requirements specified within this and any site-specific procedures. Hazards In relation to undertaking work activities involving a lead process, and / or a lead-risk job, a safe system must be implemented to control risks to health and safety arising from hazards and issues such as, but not limited to: inhalation of lead dust / fumes; skin contact with lead containing materials; and ingestion of lead dust / lead containing materials. HBIRDPRO_562504 20100908100837405.DOC Page: 3 of 19
Controls Purchasing 1. When purchasing products use the Hierarchy of Controls by replacing/eliminating lead based products and activities where possible. Work Method Statement 2. Where a Work Method Statement indicates that a worker(s) may be exposed to a lead hazard: the exposure is to be prevented; or if that is not practicable reduce the exposure to as low a level as is necessary to minimise the risk to health, but in any case the exposure is to be less than the National Exposure Standard for lead; and the Risk Assessment is to be considered in selection of control measures and is to be attached to the Work Method Statement. Note: Refer to HB#537700: Hazard and Incident Management, for further information regarding undertaking a Work Method Statement. Material Safety Data Sheets (MSDS) are to be obtained before a Lead containing substance is stored/ used on site, and are to be made readily available to workers. A copy of the MSDSs must be kept close enough to where the substance is being used to allow a worker who may be exposed to the substance to refer to it easily. These are to be updated on at least a 5 yearly basis or sooner where the MSDSs is changed or updated. Each site (including offices) is to: Implement a formal, document process for ensuring new lead substances are approved for use on site; and Keep and maintain and up-to-date Hazardous Substance Register containing a detailed list of all Lead substances stored or handled at the site, in addition to all associated MSDSs. Details of all Lead Substances risk assessments are also to be kept with the Lead Substance register (e.g. in Chem Alert) The lead Substance Register is to be readily available to any worker that may be exposed to a Lead stubstance. Chem Alert may be used to store the Lead Substance Register and risk assessments. 3. All lead contaminated waste must be disposed of as a regulated waste as per the Waste Management Procedure (HBIRDPRO-#560085-Waste Management). 4. Each site is to implement processes to review on a regular basis the management of Lead Substances on site. Labelling 5. All containers of Lead substances, including those delivered to and those produced within the site, are to be labelled in accordance with the National Code of Practice for the Labelling of Workplace Substances and the Qld Code of Practice for Hazardous Substances. These labels should not be interfered with. 6. Where a Lead substance is decanted and is not completely used immediately and the container cleaned of the Lead substance, the container into which the substance is decanted is to be labelled with the Lead product name and the risk and safety phrases and remain labelled until all of the Lead substance is removed from the container (i.e. after the container has been cleaned). HBIRDPRO_562504 20100908100837405.DOC Page: 4 of 19
7. The following information is required on the labels for all containers regardless of capacity (excluding Lead substances as detailed above): identification information: signal word(s) and / or dangerous goods class and subsidiary risk label(s) (where applicable); product name; chemical name; United Nations (UN) Number (where required by the ADG Code), and ingredients and formulation details (where relevant); risk phrase(s); * safety phrase(s); * directions for use (where appropriate); first aid procedures; emergency procedures; details of manufacturer or importer; expiry date (where relevant); and reference to the MSDS. * Refer to the National Code of Practice for the Labelling of Workplace Substances for selected Risk and Safety Phrases. Labels are to be firmly secured and printed in a colour / colours which provide a distinct contrast to the background colour. All information on labels is to be: on an outside face of the container; in the English language; in durable print; and in lettering of a size and style which is easily legible. Where the lead substance s container is too small for a label to be attached to the container, the label may be securely attached using other means (e.g. string around the neck of the container) or butterflied to ensure that relevant information is readable. A labelled container may only be used to hold the Lead substance indicated on the label. Where an MSDS is amended by a manufacturer / supplier, relevant label(s) are to be reviewed to ensure they contain the correct information. Articles which give rise to Lead substances during their use, (e.g. certain welding rods), are to be appropriately labelled indicating the conditions of use that can lead to the generation of Lead substances. Note: Labels can be printed from ChemAlert. 8. Suitable controls to minimise lead exposure and / or lead contamination may include: the use of non-lead materials or materials with a lower lead content; the use of lead compounds in emulsion, paste or other wet forms which will prevent or minimise the formation of dusts; testing for the presence of lead prior to starting work; the use of barriers / exclusion controls etc. to prevent unauthorised personnel from being exposed to a lead hazard; local exhaust ventilation (i.e. designed and installed by a competent person); wet work methods* (i.e. wetting of lead materials and surfaces during activities such as grinding, rubbing and scraping down lead painted surfaces, and the wetting of work benches etc.); and suitable PPE. HBIRDPRO_562504 20100908100837405.DOC Page: 5 of 19
Note: Wetting is not to be used where such a method may pose a hazard to workers, such as at furnaces or where electrical safety cannot be maintained. 9. As far as is practicable, any contamination by lead is to be confined to the area where the lead process is undertaken. 10. Workers are not to eat, drink, chew gum, smoke or carry smoking materials in any lead process area, and are to remove lead contaminated clothing and equipment, and wash their hands and faces before entering any area provided for eating and drinking. Cleaning 11. Cleaning of areas that may be contaminated with lead is to be done as frequently as necessary to ensure cleanliness and the removal of lead deposits. In particular, the following is to be cleaned (where relevant) at the recommended minimum frequencies: floors and workbenches at least once per day; external plant surfaces where practicable, and according to the degree of contamination, once per day; washing and changing rooms, and facilities for eating and drinking at least once per day; and other fixtures, ledges etc., are to be cleaned as frequently as necessary to prevent the accumulation of lead deposits. 12. Cleaning methods must not spread lead. Acceptable methods for cleaning include: the use of fixed vacuum cleaning apparatuses; and wet cleaning methods, such as mopping. Note: Compressed air, compressed gas or dry sweeping methods are not to be used for cleaning. 13. Where lead-containing paint is to be removed, it is to be undertaken in accordance with this corporate standard and AS 4361.1-Guide to lead paint management-industrial applications. Removal / Exclusion from a Lead-risk Job 14. A worker is to be removed / excluded from undertaking a lead-risk job where the worker is pregnant or is breast feeding; has a medical condition that may be adversely affected by exposure to lead; or is considered (by SCL or the worker themselves), to have been exposed to an excessive level of lead. Where a worker is suspected to have been exposed to an excessive level of lead, the worker is to cease the lead-risk job, and ensure that health surveillance is carried out on the worker as soon as possible (but no later than seven (7) days), after the worker has been removed from the lead-risk job. Where a worker s blood lead level is found, through health surveillance, to be at or above the relevant level listed in Table 1 below, the worker is not to be permitted to return to the lead-risk job (refer 16). HBIRDPRO_562504 20100908100837405.DOC Page: 6 of 19
Table 1 Blood lead levels for which removal from a lead-risk job is necessary 2.41 µmol/l (50µg/dL) for males and females not of reproductive capacity 2.41 µmol/l (50µg/dL) for males of reproductive capacity 0.97 µmol/l (20µg/dL) for females of reproductive capacity 0.72 µmol/l (15µg/dL) for females who are pregnant or breast feeding A worker who has been removed from a lead-risk job is not to return to the lead-risk job unless the designated doctor, after determining the worker s confirmed blood lead level is below the relevant level listed in Table 2 below, advises that the worker may return. Table 2 Blood lead levels under which a worker may return to a lead-risk job 15. 1.93 µmol/l (40µg/dL) for males and females not of reproductive capacity 1.93 µmol/l (40µg/dL) for males of reproductive capacity 16. A l 0.48 µmol/l (10µg/dL) for females of reproductive capacity, including females who have l ceased their pregnancy and are not breast feeding. reports / records regarding a worker s removal and / or return to a lead-risk job are to be maintained, and are to include: the name, sex and date of birth of the worker; the date on each occasion the worker was removed from the lead-risk job and the blood lead level reached; the corresponding date on which the worker returned to the lead-risk job; and a brief description of the actions taken to remove that worker from the lead-risk job. 17. A relevant person who is an employer or employer s representative must not disclose to anyone, other then the worker or someone with the workers written consent, the contents of a worker s medical record. Note: Refer to the records section in this document, for details regarding the duration in which specific records are to be kept by SCL. Personal Protective Equipment (PPE) Note: Control of lead exposure is to be achieved as far as is practicable by measures other than the sole use of PPE. The use of PPE as a control measure is to be regarded as applicable only where other controls are not practicable or do not adequately control exposure to lead. 18. Suitable PPE is to be provided to workers who are to perform a lead process and / or lead-risk job, and to those workers who may otherwise be exposed to a lead hazard on site. 19. Specific PPE requirements will depend on the particular activity that is to be undertaken, and is to be decided through the Work Method Statement process. Suitable PPE where a lead hazard may exist, includes: suitable / approved respirator (i.e. in accordance with AS 1715); protective clothing (e.g. overalls, aprons etc.); suitable head covering (particularly where a lead dust hazard exists); disposable overshoes; and suitable gloves. HBIRDPRO_562504 20100908100837405.DOC Page: 7 of 19
20. Where lead contamination of protective clothing is heavy, the protective clothing is to be vacuumed prior to removal, or respiratory equipment is to be worn during disrobing of the contaminated items. Note: respiratory equipment is only to be removed once the contaminated items have been totally removed. Note: Compressed air is not to be used for cleaning protective clothing / equipment. 21. Lead contaminated clothing is to be laundered on site (where relevant) in such a way as to prevent the spread of lead contamination (i.e. workers are not to take lead contaminated clothing off site/home with them). 22. Where lead contaminated protective clothing is sent off site for cleaning, it is to be placed in a suitable impermeable container or bag marked LEAD CONTAMINATED CLOTHING. Workplace Monitoring 23. Where a risk assessment indicates that a lead process may include a lead-risk job, atmospheric monitoring is to be undertaken by a competent person: at intervals of not longer than 12 months (where relevant); as soon as practicable following significant change in the use or composition of lead-containing materials used in that job or a significant change in an existing lead process; when required to do so by an inspector; and at the commencement of a new lead process and again within four (4) weeks after the commencement of that process (where relevant). Note: Atmospheric monitoring of lead dust is to be undertaken by a competent person in accordance with AS2985 Workplace atmospheres Method for sampling and gravimetric determination of respirable dust and / or AS 3640 Workplace atmospheres Method for sampling and gravimetric determination of inhalable dust (where relevant). 24. The results of all atmospheric monitoring are to be recorded, and are to include the following minimum details: the level of lead measured and when the monitoring was done; what monitoring procedures where adopted, including the duration of the sampling; the locations where samples where taken, the operations in progress at the time and, in the case of personal samples, the names of those workers; whether the results reflect normal operating conditions; how the results where interpreted; and the effectiveness of controls. 25. Workers with potential for exposure to lead are to be provided with a copy of the atmospheric monitoring results as soon as they become available. Health Surveillance 26. SCL workers are to be examined by a designated doctor* prior to commencing any lead-risk job, and on every occasion in the first six (6) months of employment when biological monitoring is carried out. Note: Any doctor who is to carry out health surveillance on an SCL worker, is to be competent in accordance with the NOHSC Competencies for Health Surveillance, 1998. 27. Biological monitoring is to be undertaken for a worker who commences a lead-risk job: as soon as possible, and within one (1) month from commencement of the lead-risk job; again two (2) months later; and once more, no later than six (6) months from the commencement of the lead-risk job.

Note: Refer also to HB#562498: Monitoring and Health Surveillance, for further information regarding monitoring and health surveillance. 28. Biological monitoring is to be undertaken by the designated doctor in accordance with the relevant / applicable Australian Standard(s) (refer - Attachment 3), and in consultation with the SCL Occupational Health Nurse (where relevant). 29. The frequency of further biological monitoring for a employee is to be determined by the designated doctor, based on the employee s latest biological monitoring results (refer Attachment 4). 30. A copy of the relevant risk assessment relating to the lead-risk job is to be provided to the designated doctor upon request, and that health surveillance report(s), and / or biological monitoring results are obtained from the doctor as soon as possible. a) A copy of the health surveillance results / report is to be provided to the employee(s) for whom the health surveillance / biological monitoring was undertaken, as soon as the results become available. Note: Health Surveillance Reports are to include information about: the effects on a person s health related to the person s exposure to lead because of a lead-risk job; and the need (if any) for remedial action; and the type of remedial action required. b) The results of all health surveillance are to be forwarded to the relevant statutory health and safety authority for the particular state / territory, within six (6) months of receiving the report(s). Records 31. The following minimum records relating to lead, are to be maintained / filed on site: risk assessment reports / records indicating a need for atmospheric monitoring and / or health surveillance, and the results of each employee s assessment and health surveillance reports (to be kept for minimum of thirty (30) years); risk assessment reports / records not indicating a need for atmospheric monitoring and / or health surveillance (to be kept for minimum of five (5) years); results of all atmospheric monitoring* undertaken on site; each employee s removal and return records (kept for the duration of employment, and a minimum of thirty (30) years thereafter); and details of all training / instruction given to workers regarding lead. Note: As most lead-risk jobs are likely to be contracted out by SCL, copies of atmospheric monitoring results etc. are to be obtained from the relevant contractor (where relevant). 32. Employees health surveillance records are to be marked and kept strictly confidential, in accordance with HB#560221: Information Management Policy. HBIRDPRO_562504 20100908100837405.DOC Page: 9 of 19
