Brief descriptions of the facility and engineering concepts for the conduct of microbiological research are also provided. Use techniques with known low exposure potential such as encapsulation and removal/replacement instead of hand scraping with a heat gun. Engineering Controls. These systems require that the gun and shielding gas flow rates be carefully balanced to maintain weld quality and still provide good exhaust flow. 0000013048 00000 n In certain applications such as abatement in buildings, wet methods can significantly reduce the generation of lead-containing dust in the work area. Garbing Engineering - engineering controls are measures such as using operating plant, tools, machinery and equipment to automate chemical processes or safely store chemicals. 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). Vacuum Blasting Lead-Based Paint Structures. The pellets impinge on the surface and then sublime, leaving only paint debris to be cleaned up. 0000017213 00000 n The NIOSHEngineering Controls Database has examples of published engineering control research findings. Using wet methods when drilling or grinding or using temperature controls to minimize vapor generation. In the industrial arena, some disadvantages of chemical stripping are that containment and collection of the waste materials may be difficult and productivity may be low compared with the rate for conventional abrasive blasting. 0000012158 00000 n Containment primary engineering controls AKA a hood, BSC, CACI, etc define containment primary engineering control (C-PEC) a ventilated device designed to minimize HD exposure to environment and personnel when directly handling HDs C-SEC stands for. Until recently, abrasive blasting work was conducted in unobstructed air. If this must be diluted, then sterile water is to be used. If encapsulation is used over a surface covered with intact paint, little dust is generated and cleanup and waste disposal problems are therefore minimized. Directory of Engineering Controls Engineering controls protect workers by removing hazardous conditions or by placing a barrier between the worker and the hazard. Because of the water, this kind of jetting generates little dust. Non-ventilation engineering controls can also include devices developed for the pharmaceutical industry, including isolation containment systems. Engineering controls protect workers by removing or reducing hazardous conditions such as harmful dust or dangerous noise levels. The cost of cryogenic cleaning, however, is still often prohibitive.

Dilution ventilation, on the other hand, allows lead particles generated by work activities to spread throughout the work area and then dilutes the concentration of particles by circulating large quantities of air into and out from the work area. You can review and change the way we collect information below. The sodium bicarbonate will not remove paint, rust, and mill scale as efficiently as sand or slag abrasives. Substitution is using a safer alternative to the source of the hazard. 0000003179 00000 n If the lead debris can be adequately filtered from the water, the volume of debris is low. One of the most common flexible isolation systems is glovebox containment, which can be used as an enclosure around small-scale powder processes, such as mixing and drying. These miscellaneous activities occur in conjunction with lead abatement or in-place management activities that have been previously addressed (i.e. Some chemical stripping products are toxic (e.g. No lead-contaminated items are permitted to enter the clean change area. 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). Designs for the containment structure and ventilation systems should be specific to each task, because conditions can vary substantially from one worksite to another. 0000029049 00000 n E.

These workers are not directly involved in the lead-generating activity but may nonetheless be exposed to lead in the course of their work. Exposures are likely to be highest when insulation is blown into place in a confined space. The risk of silicosis is high among workers exposed to abrasive blasting with silica-containing media, and this hazard is difficult to control. with a less hazardous one. Most biological enzymes become denatured when they are heated and lose their ability to catalyze reactions. /T1_2 8 0 R The personal hygiene measures described above will reduce worker exposure to lead and decrease the likelihood of lead absorption caused by ingestion or inhalation of lead particles. Because the abrasive exposes the bare substrate, inhibitors such as sodium nitrate or amines are often added to the water to prevent flash rusting. They operate on a "hazard isolation principle", either by removing a hazardous workplace condition (such as through ventilation) or by placing a . 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. This is especially true when used for multiple workers on a daily basis. The health hazard in these operations arises from lead fumes becoming airborne. Most soldering operations occur at temperatures that are less than 800F. 1 0 obj Lead caulking is used in commercial construction building applications, most commonly in the joining or sealing of cast iron soil pipes. High-pressure water jetting (6,000 to 25,000 psi) utilizes a pressure pump, a large volume of water, a specialized lance and nozzle assembly and, in some cases, a supply of inhibitor to prevent flash rusting. BSCs or CAI/CACI, True or False, CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Figure V:3-1.
