engineering controls and containment devices quizlet22 Apr engineering controls and containment devices quizlet
Encapsulation is particularly attractive as a control method when large surfaces such as walls, ceilings, and floors are involved because encapsulation requires little containment or cleanup and does not threaten the environment. Chemical stripping, vacuum-shrouded hand tools, vacuum blasting, or other suitable method may be used. /TrimBox [0.0 0.0 504.0 720.0] While elements of the PPE program depend on the work process and the identified PPE, the program should address: Employers should not rely on PPE alone to control hazards when other effective control options are available. Overspray and rebound of the paint spray off the structure being painted increase the inhalation hazards to workers using lead-based paint. Figure V:3-1. Although this list of operations is extensive, it is not necessarily inclusive (i.e, other construction activities not mentioned here may also involve lead exposure). 0000003179 00000 n Non-ventilation engineering controls can also include devices developed for the pharmaceutical industry, including isolation containment systems. In pharmaceutical compounding, the term "primary engineering control" usually refers to a device used to reduce the number of airborne particles and microorganisms in the compounding suite by channeling filtered unidirectional high-efficiency particulate air into areas that must be as contaminant free as possible. All information these cookies collect is aggregated and therefore anonymous. Occupational Safety & Health Administration. Workbench, Which one has Improved protection of operator: Complete enclosure of moving parts of machinery; Complete containment of toxic liquids or gases; Glove box operations to enclose work with dangerous microorganisms, radioisotopes, or toxic substances; and. >> We take your privacy seriously. Engineering controls: process containment and process upset controls Term 1 / 9 Closed environment drain system Click the card to flip Definition 1 / 9 A system of devices such as pumps, piping, and scrubbers to prevent the release of liquids, gases, and vapors to the atmosphere. -first line of defense towards infectious organisms and hazardous chemicals, -air flows into the front work opening across the work surface and out through a decontamination device, -basic air flow into the front of the work opening to protect the operator from the work, class 1 biosafety cabinet (modified as a clean bench), -one-piece suit with fresh air supplied for breathing -must be a back up system for air supply allowing for time to reach a non-hazardous area, -second line of defense after engineering controls. Summary of Secondary Engineering Controls Required for Each Classification of Compounded Sterile Preparation (CSP) Type of CSP per USP Chapter <797> ISO Class Requirement Segregated Compound- This technique does not create a profile (mechanically induced toothing pattern to enhance the adhesion of high-performance coatings) on its own, but if the original surface was blast cleaned, high-pressure water jetting can be used to remove the old paint and restore the original profile. Purpose. They are useful when employers are in the process of implementing other control methods from the hierarchy. Each can be used with or without a local exhaust ventilation control. Productivity can be high with this method if the objective is to remove only loose, flaky paint. 0000023219 00000 n You will be subject to the destination website's privacy policy when you follow the link. Moving containment enclosures involves the setting up, tearing down, and handling of flexible nylon, plastic, and cotton tarpaulins as well as framing members which together form the sides of the enclosure. If you do not allow these cookies we will not know when you have visited our site, and will not be able to monitor its performance. S. Use of Lead-Containing Mortar in Chemical (Acid) Storage and Process Tanks, T. Handling Lead Shot, Bricks, or Sheets, and Lead-Foil Panels, U. Reinsulation Over Existing Mineral Wool, V. Removal and Repair of Stained-Glass Windows. Projects such as the abrasive blasting of bridges, elevated highways, water towers, and storage tanks are likely to involve some type of containment structure. /Resources << A competent person is defined by the standard as one who is capable of identifying existing and predictable lead hazards and who has authorization to take prompt corrective measures to eliminate them. Economic Analysis of OSHA's Interim Final Standard for Lead in Construction. This process is repeated several times until the metal is too cold to pour. Vacuum blasting has several disadvantages (Knoy 1990). Lead health hazards in this operation, as in welding and torch cutting, are from lead that is superheated and released into the worker's breathing zone in the form of a fume. BSCs are only one part of an overall biosafety program which requires consistent use of good In this type of blasting, the blast nozzle has local containment (a shroud) at its end, and containment is usually accomplished through brush-lined attachments at the outer periphery and a vacuum inlet between the blast nozzle and the outer brushes. a device or room that provides an ISO Class 5 environment for the exposure of critical sites when compounding CSPs. 0000020258 00000 n The only difference in the provisions applying to these groups is in the degree of respiratory protection required. Speciality contractors are hired to do this work. This means that it cleans more efficiently and removes tight paint and rust more effectively. Partial or full containments can be used to contain entire structures or portions thereof. These particles are removed from the work area by the built-in vacuum system. Ultrahigh-pressure water jetting utilizes pressurized water at pressures in excess of 25,000 psi. 1990. The construction activities identified range from those such as abrasive blasting and welding, cutting, and burning, where exposures to lead are often high, to encapsulating lead-based paint or using lead pots, where exposures are generally low. It is the preferred solution to protect workers because no exposure can occur. endobj When all feasible engineering and work practice controls have been implemented but have proven inadequate to meet the PEL, employers must nonetheless implement these controls and must supplement them with appropriate respiratory protection. Other members of the household may then be exposed to harmful amounts of lead. An engineering control measure is one that eliminates, isolates, or removes a hazard from the workplace; things used in the workplace to help reduce the risk of an exposure. They help us to know which pages are the most and least popular and see how visitors move around the site. 0000016984 00000 n Y. Power-tool cleaning involves the use of power-operated impact, grinding, or brushing tools. Administrative controls establish work practices that reduce the duration, frequency, or intensity of exposure to hazards. Centers for Disease Control and Prevention. Personal hygiene is also an important element in any program to protect workers from exposure to lead dust. Containment or enclosure structures can be broadly classified as either partial or full. Encapsulation is the best strategy if it provides relatively long term protection and does not require routine maintenance to ensure the integrity of the encapsulant. Because many corrosion inhibitors (e.g., nitrates, nitrites, and amines) raise industrial hygiene concerns, their use must be considered carefully. Lead dust on overhead ledges, equipment, floors, and other surfaces must be removed to prevent traffic, vibration, or random air currents from re-entraining the lead-laden dust and making it airborne again. These controls focus on the source of the hazard, unlike other types of controls that generally focus on the employee exposed to the hazard. Use of techniques with known low exposure potential, such as encapsulation and removal or replacement instead of hand-scraping and hand-sanding. Order entry Engineering controls are the first line of defense in protecting workers from hazardous exposures. Vacuum Blasting of an Elevated Water Storage Tank. The abrasive also conditions the substrate, forming a "profile" of the metal, which improves the adherence of the new paint. 12.1-1 What are the types of engineering controls? The engineering control methods that can be used to reduce or eliminate lead exposures can be grouped into three main categories: (1) substitution; (2) isolation; and (3) ventilation. NIOSH. Typically, five to ten gallons of water per minute are used. After completion, the sides of the containment (tarpaulins and framing) are dismantled so that the structure can be moved forward to the next section of the bridge to be worked on. Controlling the environmental hazards are part of the directive to decrease the potential for the spread of bloodborne pathogens and other potentially infectious agents. Linking to a non-federal website does not constitute an endorsement by CDC or any of its employees of the sponsors or the information and products presented on the website. Contract No. Electricians soldering electrical connections, plumbers soldering nonpotable water lines, or roofers repairing tin flashing could all experience these short-term and intermittent lead exposures. Health Hazard Evaluation Report. The only difference in the provisions applying to the three categories of tasks is the degree of respiratory protection required. /T1_3 10 0 R Separate clean and dirty change areas are essential in preventing cross-contamination of the employees' street and work clothing. /Rotate 0 The SPCC rule requires facilities to develop, maintain, and implement an oil spill prevention plan, called an SPCC Plan. Documentation of encapsulation is important because of the potential for exposures to underlying lead-based paint during maintenance, future renovation, and eventual demolition. Additional exposures to lead can occur when lead sheets and bricks are fused with a welding torch or cut with a power saw when they are made into shielding containers. The advantages of vacuum blasting are that most of the waste material and abrasive is collected at the site of generation and is therefore not transported to the breathing zone of the worker, and that there may be little or no need for containment. Engineering controls besides the fume hood include compressed gas cabinets, vented storage cabinets, and local exhaust ventilation (LEV) such as capture hoods (canopy and slot) and snorkels, which capture and entrain chemical vapors, fumes, and dusts at the point of generation. Vacuuming is considered the most reliable method of cleaning dusty surfaces, but any effective method that minimizes the likelihood of re-entrainment may be used (for example, a wet floor scrubber). Unless the component is seriously deteriorated, occupational exposures during this operation are minimal. Premier is a healthcare alliance entirely owned by more than 200 of the nation's leading not-for-profit hospitals . The NIOSHEngineering Controls Database has examples of published engineering control research findings. In this configuration, the blast nozzle has local containment (a shroud) at its end and containment is usually accomplished by brush-lined attachments at the outer periphery and a vacuum inlet between the blast nozzle and the outer brushes (Waagbo and McPhee 1991). Dynamic Conditions relating to clean area classification under conditions of normal production. A device or barrier that is designed to help separate the hazard from the operator Prevention through Design is an approach to proactively include prevention when designing work equipment, tools, operations, and spaces. specific ISO class, Location for activities such as: If this must be diluted, then sterile water is to be used. %PDF-1.4 % To conduct these efforts, NIOSH works collaboratively with partners both in the United States and around the world. Productivity is lower than for open abrasive blasting using more traditional abrasives, according to contractors who have used this product (CONSAD 1993). Encapsulation may be a temporary measure because the lead-based paint that remains under the encapsulant may have to be disturbed at a future time and create a new potential for lead exposure. Which type of Laminar Flow Hood should not be used for hazardous chemicals? These cookies perform functions like remembering presentation options or choices and, in some cases, delivery of web content that based on self-identified area of interests. wYQ#g0. High levels of airborne total dust and lead dust can be generated by breaking lead-painted plaster into small pieces. Because of the water, this kind of jetting generates little dust. Power tools available for paint removal include needle guns, disc sanders, grinders, power wire brushes, rotary hammers, rotary peeners, and scarifiers. Hand scraping of lead-based paints involves the use of a hand-held scraping tool to remove paint from coated surfaces. The temperature of the operation is of major importance because temperature determines the vapor pressure of the metals that are heated and therefore the potential concentration of metal fumes to which the employee may be exposed. Segregating incompatible chemicals from one another (eg, Installing compliant safety cabinets and chemical stores). If used properly, vacuum blast cleaning can achieve cleaning of good quality with minimal dust generation except in areas where access is difficult because of configuration (such as between back-to-back angles). the cabinet's recirculated air) through the front grille Engineering controls means constructed containment barriers or systems that control one or more of the following: downward migration, infiltration, or seepage of surface runoff or rain; or natural leaching migration of contaminants through the subsurface over time. 0000015971 00000 n No lead-contaminated items are permitted to enter the clean change area. Origin of the microbe, or the agent in question, and the route of exposure are also important. The preferred order of action based on general effectiveness is: Using this hierarchy can lower worker exposures and reduce risk of illness or injury. The process of heating the lead and applying it as a liquid presents an opportunity for exposure to lead-oxide fumes. Brief descriptions of the facility and engineering concepts for the conduct of microbiological research are also provided. These workers are not directly involved in the lead-generating activity but may nonetheless be exposed to lead in the course of their work. This results in an uncontrolled release of dust. % 0000022689 00000 n Elimination removes the hazard at the source. A variety of heads are available to achieve a tight seal for inside corners, outside corners, and flat surfaces. 0000001456 00000 n 0000025707 00000 n If a hazard cannot be eliminated or a safer substitute cannot be found, the next best approach is to . This chapter also describes those lead-related tasks and operations that give rise to lead exposures among construction workers. Saving Lives, Protecting People, The National Institute for Occupational Safety and Health (NIOSH), National Institute for Occupational Safety and Health, Engineering Controls for Silica in Construction, U.S. Department of Health & Human Services, are part of the original equipment design, remove or block the hazard at the source before it comes into contact with the worker, prevent users from modifying or interfering with the control, need minimal user input for the controls to work, operate correctly without interfering with the work process or making the work process more difficult, limiting access to hazardous areas or machinery, inspection and replacement of damaged or worn-out PPE, program monitoring for continued effectiveness, while other controls are under development, when other controls cannot sufficiently reduce the hazardous exposure, when PPE is the only control option available. /T1_5 17 0 R engineering controls examples -glove boxes -biological safety cabinets -physical barriers of steel, plastic, glass -hand washing facilities -eye wash stations -sharps disposal containers -biological safety cabinets -ventilating laboratory hoods -autoclaves -safer sharps devices -air barriers or air "curtains" Lint free towels or wipes are to be used to wipe the surface of the PEC. In addition, the coating being worked on may consist of several layers of lead-based paint, each of which could contain as much as 50% lead. When employee exposure is above the PEL, the lead standard requires the employer to provide, and ensure that workers use, adequate shower facilities (where feasible), hand-washing facilities, clean change areas, and separate noncontaminated eating areas. The demolition of lead-painted plaster walls or building components is usually performed by striking a wall with a sledge hammer or similar tool. (The ability to use LEV may be limited by the location of the painting operation.). The cost of cryogenic cleaning, however, is still often prohibitive. /Type /Page Certain lead-related construction tasks commonly produce exposures above the PEL and often orders of magnitude above the PEL. The following engineering controls apply: Portable local exhaust ventilation should be used to remove lead dust and particulates from localized areas. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. 1993. Engineering controls include: Sharps disposal containers; Needle containment devices; Other safety devices that prevent handlers from getting cut or poked Another method is worker rotation, which involves rotating employees into and out of contaminated areas in the course of a shift, thereby reducing the full-shift exposure of any given employee. Examples of engineering controls include installing guardrails to prevent falls, limiting exposure to hazardous chemicals via ventilation, using portable air conditioners to combat heat stress and installing noise absorption panels to dampen high noise levels. Because the abrasive exposes the bare substrate, inhibitors such as sodium nitrate or amines are often added to the water to prevent flash rusting. Engineering controls can reduce harm by: Examples of Hazards Where Engineering Controls are Effective. This activity is usually performed by workers in the plumbing trades. This heat separates the substrate, which is subsequently scraped off with a putty knife or similar tool. If the lead debris can be adequately filtered from the water, the volume of debris is low. When employees use PPE, employers should implement a PPE program. The PEC must be cleaned then disinfected daily. /Parent 2 0 R Some chemical stripping products are toxic (e.g. Containment structures vary in their design and in their effectiveness in containing debris. Because some substitute materials may have their own unique hazards, the MSDS for the substitute material should be consulted before it is used. This may include: PPE is equipment worn to minimize exposure to hazards. /Type /Pages This could include changing the work process to stop using a toxic chemical, heavy object, or sharp tool. Biosafety cabinets are used in labs working with human blood or OPIM. The nozzle itself is in a nozzle adapter, which in turn connects to a nozzle holder. the continuous-flow respirators) should be used only for abrasive blast operations where the abrasive materials do not include silica sand and the level of contaminant in the ambient air does not exceed 25 or 50 times the recommended exposure limit, respectively. Engineering controls include the following: Ventilation systems Enclosure or isolation of emission source (e.g., biological safety cabinets or fumehoods) can be used in a Type A2 cabinet if it exhausts to the These include: High-pressure water jetting with abrasive injection; Develop and implement a good respiratory protection program in accordance with OSHA requirements in. Differential pressure 0._____" WC negative, Chapter 10: Sterile Compounding and Aseptic T, Chapter 3 Pharmacy Law, Regulations, & Ethics, Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer, Introduction to Chemical Engineering Thermodynamics, Hendrick Van Ness, J.M. -the killing of all microbial life including microbial spores, -use of antimicrobial agents on inanimate subjects such as work surfaces, equipment items, agents not known to cause disease in healthy adult humans, agents with moderate hazardous potential to the personnel or environment, exposure potential to pathogens spread by aerosol inhalation, serious infection with possible lethal consequences, exposure to dangerous and exotic agents that have high individual risk of life-threatening disease that may be transmitted by aerosol with no vaccine or therapy available, handling materials in the lab setting without contact with blood or body fluids or infectious organisms, workstations where opened specimens are handled, activities which can result in the formation of aerosols, require handling of large volume of body fluids, or require prolonged exposure to body fluids, Introduction to Chemical Engineering Thermodynamics, Hendrick Van Ness, J.M. The lead exposure of this group of workers can be caused either by the activities of their co-workers or their own work-related activities. Abrasives used for injection include sand and slag materials, as well as soluble abrasives such as sodium bicarbonate. Steel Structures Painting Council, Lead Paint Removal: Meeting the Challenge, SSPC 91-05:117-130. trailer <<3FE115B2CE3646B19D51F54324A682A6>]/Prev 831446/XRefStm 2832>> startxref 0 %%EOF 709 0 obj <>stream Wet Abrasive Blast Cleaning. According to industry sources, lead slag is no longer used in the manufacture of mineral wool, although lead can be present as a trace impurity (CONSAD 1993). the grout between the tiles/brick must be restored), repaired, or relined with an entirely new lining (either tile or lead brick). Currently, some state and local regulations require the use of enclosures or containment structures to prevent the uncontrolled dispersal of lead dust and debris into the environment. Use of ventilation system like fume hoods, snorkels, etc. However, when used in confined spaces, the potential for creating an oxygen-deficient environment is significant and must always be guarded against. Pot dressing is another source of lead fumes. The other activities typically take place in a workshop and are therefore covered under the general industry lead standard (. When other control methods are unable to reduce the hazardous exposure to safe levels, employers must provide PPE. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. 0000016741 00000 n This system uses an expendable abrasive that is metered into a pressurized water jet (6,000 to 25,000 psi) for surface preparation. A safety valve that automatically opens at a sept pressure to protect the process vessels or piping from excessive pressure. In this situation, lead becomes airborne as a volatilized component of the coating. Use shrouded tools wherever feasible (shrouding can restrict accessibility to the work area) with vacuum attachment to collect dust and debris at the point of generation (Figure V:3-4). This system may employ vibrating brushes to help release the paint from the surface. This can be accomplished by employing either a downdraft or crossdraft ventilation system that is properly balanced by a make-up air supply. 0000014770 00000 n 3 0 obj PPE can be effective, but only when workers use it correctly and consistently. 0000005815 00000 n /ArtBox [0.0 0.0 504.0 720.0] 0000004789 00000 n Mini-enclosures have advantages over larger conventional enclosures because the same size fan and dust collector can achieve much higher velocities past the helmets of the workers. /T1_5 11 0 R /Parent 2 0 R ; Engineering Controls: includes designs or modifications to plants, equipment, ventilation systems, and processes that reduce the source of exposure. Although OSHA does not prohibit the use of methylene chloride-based stripping products, some local, State, and other Federal authorities may prohibit its use in residential units. A containment primary engi-neering control (C-PEC) is a ventilated device designed to minimize worker and environmental HD exposure when directly handling HDs. 4 0 obj Install partitions or other temporary barriers to allow for partial containment of dust to minimize exposures to other workers and building occupants. Biosafety Level 2 (BSL-2) BSL-2 laboratories are used to study moderate-risk infectious agents or toxins that pose a risk if accidentally inhaled, swallowed, or exposed to the skin. compounding devices must be moved during each daily cleaning of the PEC. >> /T1_4 7 0 R is, in fact, the velocity profile. Summary of Secondary Engineering Controls Required for Each Classification of Compounded Sterile Preparation (CSP) Type of CSP per USP Chapter <797> ISO Class Requirement Segregated Compound- Because most field soldering and brazing work is conducted with a torch, it is difficult to regulate operating temperatures to within recommended limits to reduce the amount of metal fumes generated. To the extent possible, replacing lead chromate with zinc. BSC or CACI must be located in ISO Class ___ Plant Engineering, March issue. By directing a worker to position the exhaust hood properly or to improve work practice, such as standing to the side or upwind of the cutting torch to avoid the smoke plume, a supervisor can do much to minimize unnecessary employee exposure to airborne contaminants. 0000029049 00000 n 0000017297 00000 n If you have additional questions about the SPCC program, please call our Oil Information Center at (800) 424-9346 or TDD (800) 553-7672. 2.2 Other Capture Devices 2.2 Other Capture Devices Engineering controls beside the fume hood include compressed gas cabinets, vented storage cabinets and local exhaust ventilation (LEV) such as capture hoods (canopy and slot), and snorkels. Mini-enclosure containment structures are usually light-weight, low wind-loading structures that isolate that area where blasting and surface priming is taking place on a given day. Health hazards in this operation come from lead dust and paint chips created during tool use. Use personal protective equipment if engineering controls and work practices alone cannot reduce hydrogen sulfide to safe levels. airlock chamber. A system used to keep external air, which may contain airborne toxic substances, from entering the building. Engineering controls are the type of controls that protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. The high-density foam cleaning medium is absorptive and can be used either wet or dry. Well-designed engineering controls can be highly effective in protecting workers and will typically be independent of worker interactions. >> The splicer pours the lead from one ladle over the copper joint and catches the excess in another ladle held below. The employer also must ensure that employees wear the respiratory protection provided when it is required. These miscellaneous activities occur in conjunction with lead abatement or in-place management activities that have been previously addressed (i.e. Cookies used to make website functionality more relevant to you. 0000002832 00000 n 1993a.
