Preamble Indian petroleum industry is the energy lifeline of the nation and its continuous performance is essential for sovereignty and prosperity of the country. As the industry essentially deals with inherently inflammable substances throughout its value chain – upstream, midstream and downstream – Safety is of paramount importance to this industry as only safe performance at all times can ensure optimum ROI of these national assets and resources including sustainability. While statutory organizations were in place all along to oversee safety aspects of Indian petroleum industry, Oil Industry Safety Directorate (OISD) was set up in 1986 Ministry of Petroleum and Natural Gas, Government of India as a knowledge centre for formulation of constantly updated world-scale standards for design, layout and operation of various equipment, facility and activities involved in this industry. Moreover, OISD was also given responsibility of monitoring implementation status of these standards through safety audits. In more than 25 years of its existence, OISD has developed a rigorous, multi-layer, iterative and participative process of development of standards – starting with research by in-house experts and iterating through seeking & validating inputs from all stake-holders – operators, designers, national level knowledge authorities and public at large – with a feedback loop of constant updation based on ground level experience obtained through audits, incident analysis and environment scanning. The participative process followed in standard formulation has resulted in excellent level of compliance by the industry culminating in a safer environment in the industry. OISD – except in the Upstream Petroleum Sector – is still a regulatory (and not a statutory) body but that has not affected implementation of the OISD standards. It also goes to prove the old adage that self-regulation is the best regulation. The quality and relevance of OISD standards had been further endorsed by their adoption in various statutory rules of the land. Petroleum industry in India is significantly globalized at present in terms of technology content requiring its operation to keep pace with the relevant world scale standards & practices. This matches the OISD philosophy of continuous improvement keeping pace with the global developments in its target environment. To this end, OISD keeps track of changes through participation as member in large number of International and national level Knowledge Organizations – both in the field of standard development and implementation & monitoring in addition to updation of internal knowledge base through continuous research and application surveillance, thereby ensuring that this OISD Standard, along with all other extant ones, remains relevant, updated and effective on a real time basis in the applicable areas. Together we strive to achieve NIL incidents in the entire Hydrocarbon Value Chain. This, besides other issues, calls for total engagement from all levels of the stake holder organizations, which we, at OISD, fervently look forward to.

FOREWORD

Hydrocarbon processing and handling entails some risks arising out of potential hazards like fires, explosions, injuries/burns to the personnel etc. Most of such hazards are taken care, to a large extent, by better understanding, safer designs of the plants and other facilities and following safe operating practices. Oil Industry Safety Directorate (OISD), constituted by the Ministry of Petroleum and Natural Gas in 1986, have been bringing out Standards and Guidelines on various aspects of designing and operation of plants and facilities to improve safety standards in the oil industry. In the changed scenario of the economy, the oil industry too is becoming highly competitive and upgradation of technology is taking place around the world to achieve excellence. The successful application of a new technology depends greatly upon its successful adaptability. Such adaptability brings the "personnel". playing pivotal role in implementation of the technology, in the forefront. It is incontrovertible that personnel are most important resource of organisation and that maintaining their health is vital for productivity and effectiveness. As such, their health should be strongly emphasised in the organisation's strategic plan. Promotion of health of employees in the widest sense, should, therefore, be a high priority, both a goal and a challenge for the organisation. With a view to provide a structured programme to look after and promote the health of the vital "Human Resource" in the oil and gas industry, the present document "Guidelines for Occupational Health Monitoring in Oil & Gas Industry" has been prepared by the Functional Committee on Occupational Health Monitoring. It is hoped that these guidelines will help in establishing and practising an appropriate Occupational Health Monitoring programme for the employees of their industry. This document will be reviewed periodically for improvements based on the new experiences and better understanding. Suggestions from industry members may be addressed to :

GUIDELINES FOR OCCUPATIONAL HEALTH MONITORING IN OIL & GAS INDUSTRY 1.0

INTRODUCTION

Technological advances while making the oil industry competitive, have also multiplied the hazards to the operating personnel in the form of complex processes and application of various hazardous chemicals. The enlightened management should consider that their duty is to preserve and promote the health of their employees and give them a good deal which in turn fosters better output and happiness in industry. Greater use of the assets of the work place - stability, long term relationships of trust and peer support can be advantageously utilised to make the work site as an effective and economical setting for various programmes designed to promote good health. The purpose of Occupational Health programme is to protect and promote the health of all employed persons. Occupational Health is not limited in scope only to diagnosis of specific occupational diseases and their treatment. It is necessary to consider not only the traditional specific hazards to health at work but also control of health problems of employees which are closely related to work conditions; are aggravated or influenced by work exposures; are susceptible to control or amelioration by interventions at work place. Occupational Health Monitoring will provide a scientific basis for decisions aimed at protection of human health from any possible adverse consequences of exposure to the hazards in the occupational environment. 2.0 SCOPE This document lays down minimum requirements for practising Occupational Health Monitoring in petroleum refineries, oil/gas exploration / production/processing plants both offshore and onshore, cross country pipelines, LPG bottling plants and other petroleum handling facilities/installations. This gives guidelines to establish Occupational Health Monitoring in the industry to provide specific level of occupational health and hygiene services to the employees and includes personal health of the individuals, the health of the occupational group, assessment of the employees' occupational environment and appraisal of the evidence linking job conditions and exposure to effect on health and course of the disease. Due to various reasons, if it is not possible to provide the required facilities of its own for the Occupational Health Monitoring at the petroleum handling facility / installation, the same should be arranged through outside agencies. 3.0 DEFINITIONS "Occupational Health Monitoring" means a service established in the place of employment for the purposes of ; (a) protecting the employees against any health hazard which may arise out of their work or the conditions in which it is carried on; (b) contributing towards the employees' physical and mental adjustment, in particular by the adaptation of the work to the employees and their assignment to jobs for which they are suited; and (c) contributing to the establishment and maintenance of the highest possible degree of physical and mental well-being of the employees. “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



Occupational Group : Means a group of individuals directly related to a particular work place on a regular basis. Threshold Limit Value - Time Weighted Average (TLV-TWA) represents the time-weighted average concentration for a normal 8-hour workday and a 40 hour workweek, to which nearly all employees may be repeatedly exposed day after day without adverse effect. Threshold Limit Value - Short Term Exposure Limit (TLV-STEL) represents the concentration to which employees can be exposed continuously for a short period of time without suffering from (1) irritation; (2) chronic or irreversible tissue change; (3) narcosis of sufficient degree to increase the likelihood of accidental injury, impair self rescue or materially reduce work efficiency and provided that the daily TLV-TWA also is not exceeded. A STEL is defined as a 15 minute time-weighted average exposure which should not be exceeded at anytime during a work day, even if the eight hour time weighted average is within the TLV. Threshold Limit Value - Ceiling (TLV-C) represents the concentration of a substance or gas that should not be exceeded even instantaneously. Biological monitoring can be defined as assessment of employee exposure by measurement of some "index" chemical in a body fluid as evidence of exposure to a chemical. The Biological Exposure Index (BEI) is defined as an "index" chemical that appears in a biological fluid or in expired air following an exposure to a workplace chemical Work area : Work Area is a place where people work. Competent person : Competent Person is a qualified Industrial Hygienist or a person trained in the techniques of Industrial Hygiene. Body Mass Index means an accepted way of finding out obesity etc. and is calculated as – 2 Body weight in kg/(Height in meter) .

OCCUPATIONAL HYGIENE MONITORING

Occupational hygiene is the science and art devoted to anticipation, identification, evaluation and control of environmental factors or stresses arising in or from the work place which may cause sickness, impaired health, significant discomfort or inefficiency among the employees. Occupational hygiene shall identify exposure to physical, chemical and biological hazards like heat, light, noise, radiation, chemicals-dust, fumes, gases, parasites etc. and to take measures to bring them under control, before the employees experience injury or evidence of any adverse signs or symptoms. “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



Occupational hygiene shall conduct the qualitative and/or the quantitative evaluation of environmental agents which pose health hazard at the work place. This shall be done by measuring exposures, evaluating their probable effects by existing toxicological and industrial hygiene standards and utilising sensitive biological examination of exposed persons to discover the entry of harmful materials into the human systems, in advance of any possible injury.

9.1 Work Environment Monitoring and Industrial Hygiene : i) ii) iii) iv) v) vi) vii) viii) ix) x)

Industrial Hygiene (IH) survey shall be done to map all the occupational health hazards in a work area and should cover all installations. The IH survey is to be carried out by a competent person. The IH survey shall be done once every 5 years. However, a major change in the process will warrant a fresh survey. The occupational health hazards should be measured with standard equipment and with accepted measurement technique. The measurement should be able to replicate human exposure to the occupational health hazard. The measurement technique shall include both area sampling and personal sampling. The Industrial Hygienist shall decide the sampling strategy taking into consideration the best practice. Occupational health risk assessment to be done based on the results of the survey. Monitoring schedule for health hazard at the work area is to be established based on the professional experience of the Occupational health team and industry experience. Ergonomic survey where possible should be done by an Ergonomist.

The quantitative aspects of safe occupational exposures should be expressed in the concepts of Threshold Limit Values (TLV), a time weighted average exposure as detailed in Annexure- I. Occupation health hazard & Industrial health survey of all facilities shall be conducted to assess the occupational health hazards like physical (noise, heat, radiation, illumination), chemical, toxic exposures, ergonomics, biological and psychological. This shall be repeated as specified for each hazard in following paragraphs or as and when there is major addition / alteration in facilities. On basis of this survey, the hazards areas shall be classified in high risk, medium and low risk areas. The main focus shall be on hazard elimination/ reduction. There shall be periodically monitoring. 9.2

Monitoring of Physical Hazards

9.2.1

Heat stress

The parameters like air temperature, relative humidity, air movement, radiant heat are taken into consideration when assessing or controlling the thermal environment. It also depends upon clothing worn, work load etc. These parameters shall be monitored during summer particularly. The heat stress at work place shall be monitored by using techniques like wet bulb globe temperature index. The acceptable limits should be arrived at depending upon heat, relative humidity, hours of working etc. “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



9.2.2

Noise

The level of noise at work place shall be monitored at least once in a year. The monitoring may be repeated in between also as per requirement. Ear plugs etc. should be provided to personnel working / entering in high noise areas. Threshold Limit Values (TLVs) for Noise exposure are given in the Table-1 of Annexure-II. 9.2.3 Illumination The illumination levels in working / movement areas shall be monitored once in six month. The illumination level be maintained above the recommended levels. Recommended levels of illuminance for various classes of visual task are given in the Table-2 of Annexure-II. 9.2.4 Radiation Radiation level from nuclear sources etc. shall be measured on a quarterly basis. In case, it exceeds the threshold value, the effect of radiation on exposed personnel shall be monitored. Personal Protective equipment shall be provided to personnel working in the area. Training shall be provided to personnel on the hazards associated with type of radiation and its preventive measures. 9.3

Monitoring of Chemical Hazards Variety of chemicals ; organic and inorganic are used as absorbents, solvents, additives, catalysts, colouring agents, laboratory reagents etc. in the oil industry. All such chemicals including which are generated/ released during the process, along with the petroleum, pose health hazards to the operating personnel. The concentration of various chemicals used shall be monitored periodically. Certain chemicals cause personal injury due to contact with or entry into the body via inhalation, ingestion, skin contact or eye contact. Health hazard may result from repeated, chronic and long term exposure to low concentration of such chemicals. Measurement methods for toxic chemicals in the work environment are given in the Table of Annexure - III.

9.4

Biological Monitoring Measurement of the concentration of substances in breathing zone air does not ensure that the employee is totally protected from adverse health effects resulting from exposure to chemicals in the workplace. The actual body burden of the chemical resulting from all routes of exposure is more directly related to potential adverse health effects. The uptake of the workplace chemical by the inhalation route, absorption of the chemical through the skin or the gastrointestinal tract and non occupational exposure to the chemical all influence the body burden. Interaction of the chemical with other environmental and workplace chemicals may stimulate or inhibit its metabolism and elimination and thus influence the toxicity of the chemical in the person exposed. “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



Thus, the environmental concentration of a chemical is related to the body burden of the same chemical under specified conditions only. To further evaluate a potential health hazard in the workplace, biological monitoring should be used. Biological monitoring can be defined as assessment of employee exposure by measurement of some "index" chemical in a body fluid as evidence of exposure to a chemical. The Biological Exposure Index (BEI) is defined as an "index" for the chemical that appears in a biological fluid or in expired air following an exposure to a workplace chemical. The BEI serves as a warning of exposure by (1) the appearance of chemical or (2) the appearance of biological response indicative of exposure. The BEI is primarily an index of exposure and not a sentinel of some health effect that may have been produced from exposure to a workplace chemical. Permissible Biological Exposure Indices for various chemicals are given in the Table – 1 of Annexure-IV. 9.5

Monitoring of Ergonomic Hazards Ergonomic monitoring of the workplace shall be done in once in three years and also when major changes in workplace is carried out and corrective action should be undertaken accordingly.

9.6

Psychological Hazards During the course of survey, attempt should be made to identify psychological hazards and corrective actions taken accordingly.

10.0 PRE - EMPLOYMENT / PRE-PLACEMENT MEDICAL EXAMINATION Guidelines for determining the medical fitness of a candidate considered for preemployment / placement in the services of the company. The organisations are empowered to relax the standards or fix a suitable standard as per the requirement of the job as a matter of policy. (1) The medical examination shall be conducted for following categories prior to appointment in the services of the company : a) Permanent /temporary/ trainee b) An employee in the services of the company who is selected for alternative job on the basis of open recruitment or otherwise; c) On deputation basis or permanent from Central/State Governments/Public Sector Undertakings. (2) Medical examination shall be conducted by the Company Medical Officer/Authorised Medical Officer who shall be the authority to certify a candidate as medically fit/ unfit/ temporarily unfit in respect of all appointments in the company.

For personnel working in Offshore, additional requirements for medical fitness are enclosed in Table – 2 of annexure – V. The selection parameters shall be as above unless specifically mentioned.

11.0 PERIODIC HEALTH EXAMINATION The periodic examination should be carried out at regular intervals after the initial pre placement examination. It may not always be necessary to conduct a full-scale medical examination at the routine periodic check-ups, especially if there are no overt signs of illness. A format shall be developed for periodic examination with emphasis on the aspects of the history and physical examination most relevant to the exposure in question. Typical format enclosed as Table 2 of Annexure IV. The scope and periodicity of the health examination should depend on the nature and extent of the risk involved. The examination should focus on the body organs and systems most likely to be affected by the harmful agents in the workplace. For example, audiometry is the most important test for those working in a noisy environment. For each harmful agent, the period between exposure and the development of a health impairment (latency period) is a major factor in determining the frequency of examination. However, in many cases the latency period is not known. For such agents, the frequency should be determined on the basis of: (a) the natural history of the disease, including the rapidity with which the biochemical, morphological behavioural, etc. changes might occur or be detected by screening tests; (b) the level of exposure to the hazardous agent and to any other interacting agent or agents; (c) the anticipated susceptibility of the exposed population and individuals. Refer Table-3 of Annexure-IV.

Frequency for General health check up The minimum frequency for general health check up should be as under : 

Medical examination every five years upto 45 years of age



Every three years after 45 years & upto 55 years of age.



Alternate year after 55 years of age.



At the age of retirement / superannuation “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



In addition, personnel working in hazardous areas shall be examined for specific parameters at frequency as given in Table-1 & 3 of Annexure- IV. 11.1 CLINICAL AND SCREENING LABORATORY TESTS Clinical and Screening Laboratory Tests for the early detection of occupational diseases in the main organs and systems shall be conducted depending upon the work environment of the personnel. General Health check up & investigation data sheet is enclosed as Table - 2 of annexure-IV. Recommended frequency for Clinical Laboratory Tests for early detection of work related illness in the main organ and system are given in the Table – 3 of Annexure-IV.

13.0 AUDIT AND PERFORMANCE REVIEW An audit is the structured process of collecting information on the efficiency, effectiveness and reliability of the total health and safety management system and drawing up plans for corrective action. A performance review involves judging performance and taking decisions to improve it based on performance measurement and audits.

13.1 AUDIT An audit may generate qualitative and quantitative information. Quantitative measurement provides a numerical measure so that improvements in performance may be measured from year to year. Audits, though generally done by an independent external agency, may also be conducted in-house by a team which is not involved with the section being audited. 13.1.1 The Audit Team The audit team should be led by a occupational health physician and should include industrial hygienist & other health and safety professionals. 13.1.2 Frequency and Initiation Each facility should undergo a formal audit at least once in 4 years. Three months prior to the audit, the auditors should ask for basic information about the facility, including about the plant layout and process, employees, production facilities, raw materials, production, health and safety policy and organization, current performance standards, industrial hygiene and occupational health summary reports for the period between the last audit and now and any other relevant information. The facility may nominate a liaison officer to work with the auditors and allocate a room for the exclusive use of the auditors when they are on the site. 13.1.3 Audit Visit The audit should begin with a meeting between the auditors and the facility management to mutually agree on the scope of the audit and the audit visit agenda. The meeting should also be used to discuss the current operating condition of the facility and the information that the auditors already have on hand. The audit should then continue with interviews with selected facility personnel, inspection of documents and records and site tours and walk-around-inspections. Copies of all industrial hygiene and occupational health documents should be made available to the auditors. Before the conclusion of the audit visit, the auditors should appraise the facility management of their preliminary findings. 13.1.4 Findings and recommendations The findings and recommendations of the auditors should be given to the facility management in the form of a formal report. The timetable for implementing recommendations should also be provided. “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



13.1.5 Audit Methodology Annexure – VI provides a typical questionnaire for conducting an audit in a hydrocarbon facility. Questionnaire needs to be modified depending upon the facilities and occupational health hazards. Audit performance may be quantified using this questionnaire to make a comparison across years for the same facility or across facilities in the same year. This, however, requires consistency in the use of the suggested audit methodology.

13.2 PERFORMANCE REVIEW The information available from performance measurement and audits are used to decide about the nature and timing of the actions necessary to remedy deficiencies. Clear responsibilities for remedial action should be fixed and remedial action should be initiated promptly after a review meeting, fixing deadlines for completion of tasks. Certain reviews, like that of performance measurement, may be an ongoing activity. They may be conducted monthly for a section, quarterly for a department and annually for the entire facility. The action that ensues from reviews need not wait for a periodic audit but may base itself on performance measurement exercises. Such action may be initiated by : i) ii) iii)

First line supervisors to remedy failures to implement performance standards which they observe in the course of routine activities. Proactive or reactive performance Measurement. Health and safety assessments made at various levels.

Key performance indicators, such as the ones given below, may be used in performance reviews for taking immediate remedial action. i) ii) iii) iv)

Compliance with performance standards. Identification of areas where performance standards are absent or inadequate. Achievement of specific objectives. Health effects or incidents, along with analysis for their causes.

It is helpful to benchmark a facility's health and safety performance against that of similar facilities by comparing prevalent risks and management practices.

Annexure – I

Threshold values 4.1

THRESHOLD LIMIT VALUES Threshold Limit Values refer to airborne concentrations of substances/levels of physical agents and represent conditions under which it is believed that nearly all the employees may be repeatedly exposed, day after day, without adverse effect. Because of wide variation in individual susceptibility, however, a small percentage of employees may experience discomfort from substances at concentrations at or below the TLV; a smaller percentage may be affected more seriously by aggravation of a pre-existing condition or by development of an occupational illness. Three categories of TLVs are specified as: 1. Threshold Limit Value - Time Weighted Average (TLV-TWA) represents the timeweighted average concentration for a normal 8-hour workday and a 40 hour workweek, to which nearly all employees may be repeatedly exposed day after day without adverse effect. 2. Threshold Limit Value - Short Term Exposure Limit (TLV-STEL) represents the concentration to which employees can be exposed continuously for a short period of time without suffering from (1) irritation; (2) chronic or irreversible tissue change; (3) narcosis of sufficient degree to increase the likelihood of accidental injury, impair self rescue or materially reduce work efficiency and provided that the daily TLV-TWA also is not exceeded. A STEL is defined as a 15 minute timeweighted average exposure which should not be exceeded at anytime during a work day, even if the eight hour time weighted average is within the TLV. Exposures at the STEL should not be longer than 15 minutes and should not be repeated more than four times a day. There should be at least 60 minutes gap between successive exposures at the STEL. 3. Threshold Limit Value - Ceiling (TLV-C) represents the concentration that should not be exceeded even instantaneously. For some substances, e.g. irritant gases, only TLV-C may be relevant. For other substances, either two or three categories may be relevant, depending upon their physiological action. It is important to observe that if any one of the three categories TLVs is exceeded, a potential hazard is presumed to exist. Wet Bulb Globe Temperature (WBGT) index is a technique adopted to measure environmental heat stress. Portable WBGT instrument consisting of three separate resistance thermometers - globe thermometer to measure radiant energy, a wet bulb thermometer to measure relative humidity and a dry bulb thermometer to measure ambient temperature is made use of. By means of a switch, each thermometer can be individually read on a scale. A fourth position of the switch integrates the outputs of the three thermometers into a single reading WBGT index which is read on a separate scale. The operation is from line power or batteries. Noise A wide range of equipment is available for measurement of sound. The basic general purpose sound level meter measures the sound levels in decibles. Portable single hand-held battery powered precision integrating sound level meters are made use of for all kinds of sound level measurements including Leq., frequency analysis “OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from the use of OISD Standards/Guidelines.”



using a filter set. Personal noise dose meters worn by working personnel are made use of to get accurate assessment of the total noise dose the wearer has received throughout his working day. These instruments are easy to use, self contained pocket size units, battery powered with concealed or visible digital display for readout. Illumination Evaluation of lighting effectiveness is not just a question of quantity of light, but also of the quality of the lighting environment. Portable, contrast, rendered by lighting systems and visual display battery powered instrument is available for measurement of general luminance, and luminance battery powered instrument is available for measurement of general luminance, and luminance contrast., rendered by lighting systems. There being no single instrument which performs acceptable under all conditions and requirements met with in practice; different types of instruments and detectors are used in various applications to obtain the monitoring characteristics required for different forms of radiation hazards. The radiation detection most widely used in survey instruments are isolation chambers, Geiger-Mueller counters, proportional counters and scintillation detectors. To assess the dose received by the individual, either film meters or Thermoluminescent dosimeters (TLD) or a combination of both are used for personal monitoring of exposure to external sources of radiation.

No exposure to continuous, intermittent, or impact noise in excess of a peak Cweighted level of 140 dB. If instrumentation is not available to measure a Cweighted peak, an unweighted peak measurement below 140 dB may be used to imply that the C-weighted peak is below 140 dB.

* Limited by the noise source - not administrative control. It is also recommended that a dosimeter or integrating sound level meter be used for sounds above 120 decibels.
