Definitions 13  Classification: Tasnee - General Information Risk Assessment The application of one or more risk assessment methods to describe ongoing hazard identification, risk assessment and determination of necessary controls for mitigation of risks. Job Safety Analysis (JSA) Is a systematic approach to identify, analyze and record the steps involved in performing a Job task. It is a method of prevention for identifying and controlling or eliminating the hazards associated with the job task, It focuses on the relationship between the worker, Definitions task, tools, and work environment, JSA is a technique that focuses on a job tasks to identify hazards before they occur. It focuses on the relationship between the worker, task, tools, and work environment Control Measure A control measure is any measure taken to eliminate or reduce the risk by way of engineering, substitution, elimination, behavioral, administrative or reduction of risk through personal protective equipment. ALARP The residual risk shall be As Low As Reasonably Practicable. Consequence A result or effect, typically one that is unwelcome or unpleasant after an event or action 14 15 has taken place.  Classification: Tasnee - General Information Risk A Combination of the probability of occurrence of an adverse effect on people, environment, assets, profits, quality or reputation of the Company and the consequences of that effect. Reduced Risk Risk remaining after the proposed mitigation. Residual Risk Definitions Risk remaining after additional control measures required. Task Supervisor It is the person that is responsible for supervising/overseeing the actual Task execution (i.e. Operation Shift Supervisor, Maintenance Supervisor, Site Project Engineer / Assigned responsible person etc.). Risk Acceptance Decision to accept a risk as per the limits of authority as described in the method section below. Company Risk Matrix (EHSS & Business) Is a document that utilizes consequence and probability to determine the risk score. 15 16  Classification: Tasnee - General Information Energy source. Any equipment or process may produce or transfer energy like Electrical, Process, Mechanical energy. Energy Isolation: Definitions Physically preventing transmission or release of energy, by disconnecting or mechanically blocking the equipment from the energy source. This is accomplished by locking out (for example a manually operated electrical circuit breaker); disconnect switch, valve, or installing a mechanical device such as a slip plate, blind etc. Lock Out Device: A device that utilizes a positive means such as a lock, either key or combination type, to hold a mechanical or electrical energy isolating device in a safe position and prevent the energizing of a machine or equipment/ A padlock that is uniquely identified by number and controlled in a register and used to isolate or lock-out equipment or electrical circuits. Positive isolation: The installation of blind or disconnecting piping in process lines or process equipment to prevent the passage of toxic and/ or flammable substances. When screwed piping is used, caps or plugs may be used to blind the open lines. Process Isolation: A means of preventing a liquid or gas process stream, from being conveyed past a pre-defined point. This can be accomplished by closing and locking a valve or positive isolation. 16  Classification: Tasnee - General Information Definitions Confined space: Any enclosure having a limited opening for entry and exit, unfavorable natural ventilation, which could contain or produce dangerous air contaminants presents serious hazards to occupants; or which is not intended for continuous employee occupancy. These include, but are not limited to drum, column, tank, heat exchanger, ducts, stack, pipe, manholes, pits, excavation more than 1.2 meters in depth and can be categorized into: ❑ Confined space category A ❑ Confined space category B 17  Classification: Tasnee - General Information Confined space Entry: The action by which a person passes through an opening into a confined space. Entry is considered to have occurred as soon as any part of the person’s body breaks the plane of an opening into the space. A confined space entry means when the head or feet of a person passes the outside limits of the confined space and enters into it. Definitions Chemical Hazards: The chemical properties of process substances pertaining to their toxicity, flammability, explosiveness, corrosiveness, reactivity, and other characteristics that, when released, create hazards to people, facilities, and the environment. 18 18  Classification: Tasnee - General Information Chemical substances: Any toxic, harmful, corrosive, irritating or smothering substance or mixture of such substances. Definitions Toxic materials: A liquid, gas or vapor and solid material capable of causing serious injury or death to person. Wet-bulb globe temperature (WBGT): Wet-bulb globe temperature a type of apparent temperature used to estimate the effect of temperature, humidity, wind speed(windchill),and visible and infrared radiation (usually sunlight) on humans. It is used by industrial hygienists, athletes, and the military to determine appropriate exposure levels to high temperatures. Extreme Temperature: A temperature which is above or below the Occupational Health limits. Explosive substance: A chemical substance that causes a sudden, almost immediate release of pressure, gas and heat when subjected to sudden shock, pressure, high temperature or chemical reaction. 19 19  Classification: Tasnee - General Information Rescue plan: A Plan that is used to rescue the persons from the Confined Space regardless of confined Space category Lifeline/Retrieval line: A line (such as a rope or similar) used for preserving or saving life. A lifeline is used to maintain contact with a person in a dangerous or potentially dangerous situation (such as Confined Space). If retrieval line is used, the line can be used for rescue in case of an Definitions emergency. Venting: Allowing gases or vapors to be released to the atmosphere or flare or a recovery system during the activities of depressurization or purging. Ventilation: Ventilating a vessel or area by using an air moving device (e.g. fan) to draw fresh air through the vessel or Ventilating by natural flow of fresh air through the equipment by natural means. Breathing Apparatus: Line-air supplied via manually operated pump or cylinders of compressed air, self- contained apparatus carried by the wearer or a recycled air system. Canisters, cartridge and other forms of filter mask do not constitute Breathing apparatus. 20 20  Classification: Tasnee - General Information Lower Explosion Limit (LEL): The minimum concentration of vapor in air below which propagation of flame will not occur in the presence of an ignition source. The LEL is expressed as a volume percentage of vapor in air. Threshold Limit Value (TLV): Toxic gas concentration above which it is not safe to work extended periods. Definitions Upper Explosive Limit (UEL): The maximum concentration of a flammable/combustible gas, vapor, mist, or dust in air that will support combustion when an ignition source is present. Gas Tester: A person who has undergone training on the use of gas detecting equipment and is authorized to conduct gas test.
