The other activities typically take place in a workshop and are therefore covered under the general industry lead standard (. The health hazards in these operations arise from lead dust and particulates, with a potential for high airborne levels in the mortar mixing area. /T1_3 9 0 R In addition, employees must not enter lunchroom facilities or eating areas while wearing protective work clothing or equipment unless surface lead dust has first been removed from the clothing or equipment by vacuuming or another cleaning method that limits dispersion of lead dust. Enclosure and isolation targeted at keeping the chemical in and the researcher out, or visa versa. a. Ne\mathrm{Ne}Ne dust "blowdown" inside a negative-pressure containment structure). 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. This page details the types of engineering controls used at UCL. Clean change areas are used to remove street clothes, to suit up in clean work clothes (protective clothing), and to don respirators prior to beginning work, and to dress in street clothes after work. 0000017213 00000 n One method the employer can use is to schedule the most dust- or fume-producing operations for a time when the fewest number of employees will be present. Sash Abrasives used for injection include sand and slag materials, as well as soluble abrasives such as sodium bicarbonate. Keep shroud flush with the surface during cleaning. Engineering controls reduce or eliminate exposure to chemical or physical hazards through the use of equipment or devices. Some fundamental and easily implemented work practices are: (1) good housekeeping, (2) use of appropriate personal hygiene practices, (3) periodic inspection and maintenance of process and control equipment, (4) use of proper procedures to perform a task, (5) provision of supervision to ensure that the proper procedures are followed, and (6) use of administrative controls. This figure shows a fume-extractor gun, with exhaust openings at the end labeled. /T1_3 10 0 R They include sharps disposal containers, self-sheathing needles, and safer medical devices, such as sharps with engineered sharps-injury protection and needleless systems. /Rotate 0 Use of a flexible duct system requires that the welder be instructed to keep the duct close to the emission source and to ensure the duct is not twisted or bent. The employer also must ensure that employees wear the respiratory protection provided when it is required. Supplemental Engineering Controls Closed System Transfer Devices (CSTDs) May NOT be used as a substitute for C-PEC, may be used in addition when compounding MUST be used when administering antineoplastic HDs Ensure CSTD is physically and chemically compatible with the specific HD No universal performance standard for CSTDs, evaluate Lead Abatement Activities (Commercial/Institutional and Residential). This section describes the job operations that take place in construction worksites and involve worker exposures to lead. Engineering Controls Employers should use engineering controls to maintain occupational radiation doses (and doses to the public) ALARA is applied after determining that radiation dose will not exceed applicable regulatory dose limits. Six inches from each side of the LAFW, When cleaning a laminar flow hood in which direction should contaminants be moving, cleanest area is cleaned first Explain your reasoning using thermodynamic concepts. In this situation, lead becomes airborne as a volatilized component of the coating. Where complete enclosure is not feasible, establish barriers or local ventilation to reduce exposure to the hazard in normal operations. 0000020258 00000 n Steel Structures Painting Council, Lead Paint Removal From Industrial Structures: Meeting the Challenge, SSPC 90-01-:95-99. Controlling exposures to hazards in the workplace is vital to protecting workers. Local exhaust ventilation (LEV) that has a flanged hood and is equipped with HEPA filtration may be appropriate where the use of LEV does not create safety hazards. What Does Engineering Controls Mean? /ArtBox [0.0 0.0 504.0 720.0] /CropBox [0.0 0.0 504.0 720.0] outside via a properly functioning _______ _________, Cabinet supply fans draw room air (plus a portion of Vacuum blasting has several disadvantages (Knoy 1990). 0000004636 00000 n 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. Liquid CO2 storage connects to a nuggetizer hopper, which works in conjunction with an air compressor to blast a surface by using dry-ice pellets. This is accomplished by pouring a tin-based babbitt material into the sockets to keep all of the strands in place within the socket. In other words, material, equipment, or an entire process can be substituted to provide effective control of a lead hazard. This may be achieved by installing sheet-rock walls on top of the paint, covering surfaces with fiberglass, or recoating housing components with a nonlead-based paint. 0000022372 00000 n Engineering controls are built into equipment or processes to minimize hazards. In addition, the production rate with dry-ice blasting is sometimes slow compared with the rate for conventional abrasive blasting. 0000005087 00000 n The health hazard in these operations arises from lead fumes becoming airborne. Brazing operations usually occur at temperatures in excess of 800F. A longer cutting torch can be used in some situations to increase the distance from the lead source to the worker's breathing zone. Hand scraping of lead-based paints involves the use of a hand-held scraping tool to remove paint from coated surfaces. Safe Working Platform: Qualities & Safety Tips, Workplace Accident; Prevention, How To Sue & How To Get A Lawyer, Engineering Controls: Definition and Examples, Warning Sign Meaning, Importance & Examples , Isolating workers from chemicals (eg, Using a self-contained lube station), Enclosing high risk operations in sealed areas (eg, Sealing off an area that is only opened during maintenance and cleaning), Extractingcontaminants from the breathing zone of workers (eg, Installing a Local Exhaust Ventilation (LEV) system), Automating tasks so workers no longer need to perform them (eg, Using robots to spray paint new cars). /Version /1.4 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. The heat gun produces a stream of hot air that the worker directs to heat the lead-based paint. maintaining aseptic environment within the isolator, For a CAI, Net displacement of air is OUT of isolator by, For a CACI, Net displacement of air IN into isolator by, CACIs (compounding aseptic containment isolator) is mostly used for, What is the correct cleaning sequence for a vertical flow hood, Pole and hooks the grout between the tiles/brick must be restored), repaired, or relined with an entirely new lining (either tile or lead brick). /MediaBox [0.0 0.0 504.0 720.0] These techniques use heat in the form of a propane, MAPP gas, or oxyacetylene flame and a filler metal (tin/lead compositions, rosin core, brazing rods) to accomplish the task of joining. All workplace surfaces must be maintained as free as practicable of accumulations of lead dust. PPE might seem to be less expensive than other controls, but can be costly over time. Substitution includes using a material that is less hazardous than lead, changing from one type of process equipment to another, or even, in some cases, changing the process itself to reduce the potential exposure to lead. endobj Use of techniques with known low exposure potential, such as encapsulation and removal or replacement instead of hand-scraping and hand-sanding.

The current OSHA lead standard for construction (29 CFR 1926.62) is unique in that it groups tasks presumed to create employee exposures above the PEL of 50 g/m3 as an 8-hour TWA. Provide thermostatic control for heat guns to restrict operating temperatures to the lowest temperature that will allow for the effective removal of lead-based paint. 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. Most soldering operations occur at temperatures that are less than 800F. Industrial vacuuming involves the use of vehicle-mounted vacuum systems to clean various areas of industrial facilities. ; Substitution: replace the hazard (e.g., hazardous products, machines, etc.) 12.1-1 What are the types of engineering controls? The NIOSHEngineering Controls Database has examples of published engineering control research findings. Lead must be included in the grout to ensure the structural integrity of the tank, i.e., lead is one of the few materials that can withstand the corrosive effects of the acids in use. As with all OSHA health standards, when the PEL is exceeded, the hierarchy of controls requires employers to institute feasible engineering and work practice controls as the primary means to reduce and maintain employee exposures to levels at or below the PEL. 0000016605 00000 n This chapter also describes those lead-related tasks and operations that give rise to lead exposures among construction workers. For the same reason, vehicles driven to the worksite should be parked where they will not be contaminated with lead. Health Hazard Evaluation Report. A recent NIOSH publication (NIOSH 1992) points out the dangers of "take-home" lead contamination. when airflow is on all sides of the object, Zone of turbulence is _____X the diameter of the object Mini-enclosures, which have smaller cross-sectional areas than conventional enclosures, can be erected. /T1_0 16 0 R /T1_6 12 0 R NIOSH Division of Safety Research. 0000002832 00000 n 0000011279 00000 n Although airborne lead exposures are virtually eliminated with this approach, wet abrasive is more difficult to handle and move than dry abrasive, and the volume of debris also increases. The abrasive material abrades the surface of the structure, exposing the steel substrate underneath. Wet abrasive blast cleaning is a modification of traditional open abrasive blast cleaning. Because of the water, this kind of jetting generates little dust. The OSHA lead standard for construction is unique in that it groups tasks (Appendix V:3-1) that are presumed to be associated with employee exposures above the PEL into three lead-exposure ranges. Workers can be informed of safe operating procedures through fact sheets, discussions at safety meetings, and other educational means. 0000006516 00000 n For work operations where the sources of lead dust generation are numerous and widely distributed (e.g., open abrasive blasting conducted in containment structures), dilution ventilation may be the best control. When employees use PPE, employers should implement a PPE program. Notice to All Users of Type CE, Abrasive-Blast Supplied-Air Respirators. Small areas and areas with gross irregularities cannot be effectively sealed by the shroud. Mill scale is not removed; however, if the surface was previously blast cleaned, the profile of the original substrate can be restored. 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). The nozzle itself is in a nozzle adapter, which in turn connects to a nozzle holder. /T1_0 6 0 R Substitution >> The pellets impinge on the surface and then sublime, leaving only paint debris to be cleaned up. Soldering and brazing operations present similar health hazards (airborne lead fumes) but to a different degree. 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). 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. An intentional or unintentional release of a gas. Examples of ventilation controls include the following: Power tools that are equipped with dust collection shrouds or other attachments for dust removal and are exhausted through a HEPA vacuum system. Figure V:3-1. 652 0 obj <> endobj xref 652 58 0000000016 00000 n In addition, all persons doing the cleanup should be provided with suitable respiratory protection and personal protective clothing to prevent contact with lead. Cookies used to track the effectiveness of CDC public health campaigns through clickthrough data. Recycling equipment must be well-maintained and regularly monitored to ensure it is removing lead effectively. In this activity, the worker uses a heat gun, a tool similar in design to a hand-held hair dryer. Work is generally organized so that blasting proceeds for approximately one-half day, followed by compressed air cleaning of the steel and application of the prime coat of paint. A device or barrier that is designed to help separate the hazard from the operator The OSHA construction standard for lead also requires that a competent person perform frequent and regular inspections of job sites, materials, and equipment. Sides 0000025707 00000 n An inset illustration also shows a fume-extractor gun in use. In this operation, the lead is typically melted above ground and then lowered by the assistant to the splicer, who is located in the manhole or underground vault. 0000012158 00000 n Which of the following is the best description of an engineering control? >> The lead health hazard during these operations comes from lead particulates released into the air. HSE Articles, HSE Jobs, HSE News, & HSE Training. Direct manipulation takes place using rubber sleeves and gloves attached with gas-tight ports, Specifically designed for compounding Administrative controls establish work practices that reduce the duration, frequency, or intensity of exposure to hazards. airlock chamber. PECs all rely on a special type of high-efficiency particle air (HEPA) filter that is >99.99% efficient in removing particles as small as 0.3 microns in size (the most penetrating particle size [MPPS], which refers to the When the sponge is dampened, it can help reduce the amount of dust generated without unduly wetting the surface. Effective substitutes reduce the potential for harmful effects and do not create new risks. /BleedBox [0.0 0.0 504.0 720.0] Applying non-lead containing paints and primers. However, long-term operating costs tend to be lower, especially when protecting multiple workers. [. 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. 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. 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. Elimination and substitution can be the most difficult actions to adopt into an existing process. Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Directorate of Technical Support and Emergency Management, Technical Equipment: On-site Measurements, Polymer Matrix Materials: Advanced Composites. Abrasive also may escape the vacuum head if the brush attachments do not seal completely around the substrate; poor seals may be caused by operator fatigue, poor work practices or irregular surfaces and edges. Welding and cutting activities that potentially involve exposure to lead can occur as part of a number of construction projects such as highway/railroad bridge rehabilitation (including elevated mass-transit lines), demolition, and indoor and outdoor industrial facility maintenance and renovation. Using local exhaust ventilation with proper filtration. NIOSH Alert: Request for Assistance in Preventing Lead Poisoning in Construction Workers. stream As the enclosures are torn down and moved, the workers involved are exposed to lead dust generated by the movement of the containment components. Examples of Hazards Where Engineering Controls are Effective, NIOSH Engineering Controls Research Program, Engineering Control Topics on the NIOSH Science Blog, Centers for Disease Control and Prevention. Employees must also wash their hands and faces prior to eating, drinking, using tobacco products, or applying cosmetics, and they must not eat, drink, use tobacco products, or apply cosmetics in any work area where the PEL is exceeded. 0000023219 00000 n If removal is not feasible, enclose the hazard to prevent exposure in normal operations. Interlock systems for lasers and machinery are other good examples of isolating processes. The National Institute for Occupational Safety and Health (NIOSH) has therefore recommended since 1974 that silica sand (or other substances containing more than 1% crystalline silica) be prohibited as abrasive blasting material. 0000014770 00000 n 0000015971 00000 n >> Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Each can be used with or without a local exhaust ventilation control. The health hazards encountered are generated by lead fumes released into the air during the heating process and lead particulates created during the scraping process. Vacuum Blasting Lead-Based Paint Structures. Any material that is being considered as a substitute for a lead-based paint should be evaluated to ensure that it does not contain equally or more toxic components (e.g., cadmium or chromates). Moreover, the worker can install insulation manually (e.g., when installing rigid preformed insulation around pipes) or mechanically using, for example, a pneumatic blower (e.g., when blowing fiberglass or mineral wool into place over existing mineral-wool insulation). The magnitude of the painter's particulate exposure to lead is dependent on the product used, its lead content, and the quantity of paint applied. You can review and change the way we collect information below. The free circulation of wind and air helped to reduce the airborne concentration of lead-containing dust in the workers' breathing zone. 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 system uses compressed air to propel the abrasive medium to the surface being cleaned; however, water (which reduces dusting) is injected into the abrasive stream either before or after the abrasive exits the nozzle (Figure V:3-1). Use techniques with known low exposure potential such as encapsulation and removal/replacement instead of hand scraping with a heat gun. Administrative or Work Practice Controls /Parent 2 0 R 0000016455 00000 n The abrasive also conditions the substrate, forming a "profile" of the metal, which improves the adherence of the new paint. Provide workers with Type CE abrasive-blast respirators; these are the only respirators suitable for use in abrasive-blasting operations. d. Ca(NO3)2\mathrm{Ca}\left(\mathrm{NO}_3\right)_2Ca(NO3)2 Install partitions or other temporary barriers to allow for partial containment of dust to minimize exposures to other workers and building occupants. Such extraction systems can reduce breathing zone concentrations by 70% or more (Hughes and Amendola, 1982). Purpose. Each biosafety level has its own specific containment controls that are required for the following: Until recently, abrasive blasting work was conducted in unobstructed air. When vacuuming equipment is used, the vacuums must be equipped with high-efficiency particulate air (HEPA) filters. -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. 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. 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. If this method is used to control worker exposure to lead, the lead standard requires that the employer implement a job rotation schedule that (1) identifies each affected worker, (2) lists the duration and exposure levels at each job or work station where each affected employee is located, and (3) lists any other information that may be useful in assessing the reliability of administrative controls to reduce exposure to lead. /GS0 13 0 R Engineering controls protect workers by removing or reducing hazardous conditions such as harmful dust or dangerous noise levels. They help us to know which pages are the most and least popular and see how visitors move around the site. 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. This is done by a crew of workers simultaneously chipping away the old mortar by hand. This mortar is then used as pointing between the tiles or bricks. endobj E. High-Pressure Water Jetting With Abrasive Injection. This is especially true when used for multiple workers on a daily basis. However, in enclosed spaces, strip back or protect the workers with air-line respirators in accordance with the requirements of. This could include changing the work process to stop using a toxic chemical, heavy object, or sharp tool. Click the card to flip Flashcards Learn Test Match Created by These miscellaneous activities occur in conjunction with lead abatement or in-place management activities that have been previously addressed (i.e. /ProcSet [/PDF /Text] These categories are enclosure movement, activities related to abrasive blasting and repainting, and activities related to lead abatement. can be used in a Type A2 cabinet if it exhausts to the Good supervision is another important work practice.
