Such materials must be collected and put into sealed impermeable bags or other closed impermeable containers. The kinds of facilities where vacuuming could result in lead exposure include nonferrous metal plants (excluding aluminum) or steel plants melting lead-containing scrap in an electric-arc furnace.

The melting point of the filler metals is usually quite low (<600F) and the activity does not generate significant concentrations of metal fumes. Work surface. Identify and use engineering controls. 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. A recent NIOSH publication (NIOSH 1992) points out the dangers of "take-home" lead contamination. /BleedBox [0.0 0.0 504.0 720.0] 0000004329 00000 n However, both productivity and the ability to remove tight paint, rust, and mill scale can be improved through the addition of abrasive to the water stream. << 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. When considering a substitute, its important to compare the potential new risks of the substitute to the original risks. and through the supply HEPA filters located 0000020737 00000 n /Type /Pages methylene chloride) when inhaled or absorbed through the skin, and many are skin irritants or skin corrosives. Containment primary engineering control (C-PEC)the device in which compounds are mixed, including a containment ventilated enclosure (CVE) commonly called powder hoods, a biological safety cabinet (BSC), and a compounding aseptic . Engineering controlsreduce or prevent hazards from coming into contact with workers. Remove wallboard by cutting it into large pieces/sections with a carpet knife or shrouded saw with HEPA vacuum attachment. In certain applications such as abatement in buildings, wet methods can significantly reduce the generation of lead-containing dust in the work area. However, long-term operating costs tend to be lower, especially when protecting multiple workers. Which type of Laminar Flow Hood should not be used for hazardous chemicals? h{pU>M6A,UP#(Bw)m B6YHQDT-"jD)J S:82(x7iIwOn 0%1D3 UfG%4*)hzU; Provide workers with Type CE abrasive-blast respirators; these are the only respirators suitable for use in abrasive-blasting operations. NIOSH Researchers reduce the risk of fall injuries and fatalities in construction by evaluating mast climber fall-arrest scenarios and providing recommendations to standards committees and equipment manufacturers. Workers can be informed of safe operating procedures through fact sheets, discussions at safety meetings, and other educational means. Where legally permitted, some elevator companies have switched the wire ropes on older elevators from sockets that utilize poured babbitt metal to wedge clamps or to sockets utilizing a thermoplastic/epoxy mixture (Personal communication, E. Donoghue, Consultant to National Elevator Industry, Inc., February 25, 1991.). the primary means of containment developed for working safely with infectious microorganisms. 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. No lead-contaminated items are permitted to enter the clean change area. endobj Engineering controls include: Sharps disposal containers; Needle containment devices; Other safety devices that prevent handlers from getting cut or poked 0000020092 00000 n 0000006516 00000 n 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. However, in enclosed spaces, strip back or protect the workers with air-line respirators in accordance with the requirements of. HSE Articles, HSE Jobs, HSE News, & HSE Training. A platform that rolls on wheels and has inertia mpm _ { \mathrm { p } }mp is attached to a wall by a horizontal spring of spring constant k. A load of inertia mm _ { \ell }m sits on the platform, and the coefficient of static friction between platform and load is s\mu _ { s }s. 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. If you need to go back and make any changes, you can always do so by going to our Privacy Policy page. /Font << 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. If a local exhaust system is properly designed, it will capture and control lead particles at or near the source of generation and transport these particles to a collection system before they can be dispersed into the work environment. 0000012412 00000 n Vacuum Blasting Lead-Based Paint Structures. If encapsulation is used over a surface covered with intact paint, little dust is generated and cleanup and waste disposal problems are therefore minimized. >> 5 0 obj 0000003873 00000 n The schedule should be adapted to exposure conditions at a particular worksite. Following major service to facility Premier, Inc. helps hospitals accelerate performance on both clinical outcomes and supply chain costs. 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. This is accomplished by pouring a tin-based babbitt material into the sockets to keep all of the strands in place within the socket. Occupational Safety & Health Administration. Finally, because only the paint is removed, the surface may need to be "brush-off" blasted with an abrasive to produce a rough surface to facilitate adhesion of the new coating. 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- Where complete enclosure is not feasible, establish barriers or local ventilation to reduce exposure to the hazard in normal operations. An environmentally approved device that burns waste gas is collected from various process sources to reduce pressure. dust "blowdown" inside a negative-pressure containment structure).
