An employee's verbal statement that he or she received an initial medical examination from a prior employer is not sufficient to discharge the employer's responsibility to offer such an examination. The standard limits only the information that can be included in the PLHCP's or specialist's written medical opinion for the employer following an examination offered to an employee for purposes of compliance with the medical surveillance provisions of the standard. 324 Blackwell Street, #1204 Washington Building However, a noticeable increase in dust emissions may indicate that the dust control system is not operating properly. If the employer anticipates that an employee will be engaged in a task for more than four hours, the employer must provide the employee, at the beginning of the shift, the respiratory protection required in the "greater than four hours/shift" column on Table 1. No, the silica standard requires employers to follow manufacturer instructions that are related to dust control. Also, from time to time we update our guidance in response to new information. at 16845. Promptly eliminating or minimizing those hazards. See 81 Fed. The standard does not preclude employers from offering employees a second medical surveillance examination that meets the requirements of paragraph (h). Among other things, OSHA's respiratory protection standard requires employers to provide a medical evaluation to determine the employee's ability to use a respirator, before the employee is fit tested or required to use the respirator in the workplace. 1926.1153(c)(1)(xiv)-(xv), the standard does not separately require employers to minimize dust emissions. Does this standard require classroom training for employees on the required subjects of the rule? 44. Reg. Does the standard require employers to conduct their own air flow assessments to ensure compliance with this requirement? If, however, an employer can ensure - either due to the nature and timing of the work, or through work practice controls - that its employees will not be exposed to silica generated by other contractors, then the employer would not need to consider secondary exposures in determining whether its employees will be exposed below the AL under any foreseeable conditions. wJ>ttvgQY II54QP@fL'%H3 However, to ensure that employees comprehend the material presented during training, it is critical that trainees have the opportunity to ask questions and receive answers if they do not fully understand the material presented to them. How can employees demonstrate knowledge and understanding of the required subjects, as required by the silica standard?
Where a given instruction is reasonably related to the level of dust generated, the standard requires employers to follow that instruction, regardless of whether that instruction serves more than one purpose. Warnings related to electrical hazards, guarding hazards, and noise hazards; Instructions regarding the use of personal protective equipment (including respiratory protection); Instructions on fueling and refueling; and. Generally, filters and dust should be handled so as to minimize worker exposures to silica dust. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov. Are handheld powered demolition hammers with bushing tools covered by Table 1? Note that in addition to describing the silica-generating tasks, the exposure control plan must also include a description of the engineering controls, work practices, and respiratory protection used to limit exposure to respirable crystalline silica. 19. H\n0E at 16836. 29 C.F.R. The requirement for training is performance-oriented in order to allow flexibility for employers to provide training as needed to ensure that each employee can demonstrate the knowledge and understanding required under the rule. Under the scheduled monitoring option, do employers have to monitor exposures every time a new job is started (and thus a new work area is created)? See 29 C.F.R. 51. Employers that follow Table 1 do not have to assess employee exposures or separately ensure compliance with the PEL. However, in many cases, employees who perform construction tasks for very short periods of time, in isolation from activities that generate significant exposures to silica (e.g., some tasks listed on Table 1, abrasive blasting), will be exposed below the AL of 25 g/m3 as an 8-hour TWA under any foreseeable conditions. OSHA considers handheld tile saws to be handheld power saws, for purposes of Table 1 (paragraph (c)(1)(ii)). 0000045340 00000 n Also, the rule calls only for minimizing the number of employees in the relevant work areas. Does the standard prohibit an employer from using compressed air as part of a task not related to cleaning clothing or surfaces? No. Employers of employees using these types of tile saws can follow Table 1 by fully and properly implementing the engineering controls and work practices in the specified paragraphs. Although many of the entries on Table 1 require employers to "[o]perate and maintain" tools "in accordance with manufacturer's instructions to minimize dust emissions," 29 C.F.R. Yes, if it is foreseeable that the exposures of employees will be affected by exposures generated by other contractors. See 81 Fed.
(Note that this is in contrast to the determination of whether an employee's exposure is covered by the standard - a determination that must be made without regard to the decrease in exposures that occurs due to the use of engineering and work practice controls. No. at 16803. This document is advisory in nature and informational in content. For example, in the case of an employee grinding concrete walls indoors, the employer should know, in advance, the area of the surface that is to be worked on in the course of a shift. 42. 20. No. No. 1926.1153(b) (competent person is an individual with the knowledge and ability necessary to fulfill the role who is capable of identifying existing and foreseeable silica hazards and who has authorization to take prompt corrective measures to eliminate or minimize them). See 29 C.F.R. If all of the jobs and tasks an employer performs are included on Table 1, can the employer comply with Table 1 exclusively, instead of following alternative exposure control methods? What are the employer's responsibilities for employees who are assigned a task that requires the use of a respirator under the standard, but are not medically able to use a negative pressure respirator? 29 C.F.R. OSHA does not intend for the standard to prohibit all employees from entering entire areas of a construction site simply because employees in those areas are performing some work involving the generation of silica. See 29 C.F.R.
0000022688 00000 n If an employee is required by the standard to use a respirator at any time during a given day, regardless of the duration of the respirator use, that day counts as one day toward the 30-day threshold for medical surveillance. Many of the entries on Table 1 require employers to "[o]perate and maintain" tools "in accordance with manufacturer's instructions to minimize dust emissions." The tasks of filter cleaning and dust disposal are not separately listed on Table 1, but will often be performed as part of a Table 1 task. Thus, for example, if the materials being disturbed or the conditions under which the tasks are performed are relevant to the level of exposure related to a particular task, that information must be included (e.g., using a stationery saw outdoors to cut concrete). How can employers comply with the requirement to ensure that employee medical records are maintained for the proper period of time when they do not receive a copy of the PLHCPs written report to the employee? Reg. Employers must also ensure that filter cleaning and dust disposal are covered in their written exposure control plans, when required by paragraph (g)(1)(i). Reg. The standard requires employers to make and maintain records of certain information, including air monitoring data, objective data, and medical surveillance data. See 29 C.F.R. 1926.1153(d)(2)(iii), (d)(2)(iv). Does the standard require employers to document their review and evaluation of the written exposure control plan? 30. For example, a work area with only a roof that does not affect the dispersal of dust would not be considered enclosed; however, an open-top structure with three walls and limited air movement could be considered enclosed.
Thus, a "day" of respirator use for purposes of the 30-day threshold does not mean a full day of respirator use. (888) 998-1557 1926.1153(h)(7) or (h)(3), respectively. In addition, employers must not allow compressed air to be used to clean clothing or surfaces where such activity could contribute to employee exposure to respirable crystalline silica unless: (1) The compressed air is used in conjunction with a ventilation system that effectively captures the dust cloud created by the compressed air, or (2) No alternative method is feasible. The standard does not specify how employers should review and evaluate the effectiveness of the written exposure control plan. 29 C.F.R. See 29 C.F.R. The standard does not require employers to demonstrate that wet methods, a HEPA-filtered vacuum, or other methods are impossible to use in order to establish "infeasibility" for purposes of paragraph (f). What constitutes an enclosed area for purposes of compliance with Table 1? Occupational Safety & Health Administration, Occupational Safety and Health Administration, 1. Employers may also use compressed air for housekeeping when the compressed air is used in conjunction with a ventilation system that effectively captures the dust cloud created by the compressed air, or if no alternative method for cleaning clothes or surfaces is feasible. at 16837. However, if the employer experiences unforeseen difficulties or other circumstances that are expected to extend the task duration beyond four hours, the employer must provide the respiratory protection required in the "greater than four hours/shift" column as soon as it becomes evident that the duration of the task may exceed the 4-hour threshold. As a result of the new industry standards in place in regards to silica dust, Chemtek developed the NeSilex formula in 2017. Employers must ensure that in-house PLHCPs, like all PLHCPs performing medical surveillance examinations and procedures under the silica standard, adhere to the standard's confidentiality requirements. Employers performing tasks listed on Table 1 can choose to follow alternative exposure control methods in paragraph (d) instead of implementing the controls specified on Table 1. The standard does not specify the engineering or work practice controls to be used during filter cleaning and dust disposal. 1926.1153(a). Does the silica standard preclude in-house health care providers from performing the required medical surveillance examinations? OSHA began enforcing the silica standard for the construction industry specifically on September 23, 2017.1, OSHA began enforcing the silica standard for general and maritime industries on June 23, 2018. Any such comprehensive plan can be used on all of an employer's worksites if it addresses the materials, tasks, and conditions that are relevant to the work being performed. 49. The silica generated by these tasks can migrate to employees of other contractors. 0000006538 00000 n 1926.1153(j). Are there specific engineering or work practice controls employers must implement during this task? Under the standard, can an employer require employees who participate in medical surveillance to see a health care professional of the employer's choice? 0000001893 00000 n When tasks are performed indoors or in enclosed areas, the dispersal of dust can be impeded, causing dust concentrations to build. There is no set method employers must use to ensure employees demonstrate knowledge and understanding of the required subjects. at 16721.
1926.1153(g)(4). Coming up in the near future, hydraulic fracturing, as well as other operations in the oil and gas industries are required to implement dust controls by June 23, 2021.1, A Simple Solution to Comply with Regulations. 29 C.F.R.
1926.1153(h)(7), an employer with a specialist on staff may elect to have the additional examination(s) performed by that in-house physician. 1910.1020. 1926.1153(c). HEPA filter - high-efficiency particulate air filter The employer must also obtain a written medical opinion from the PLHCP within 30 days of each exam, which contains more limited information than the report to the employee. Employers may designate an existing employee as the competent person provided that employee qualifies as a competent person under the standard. 0000039473 00000 n 1926.1153(g)(1)(i)-(iv), (g)(4). 1926.1153(d). If a PLHCP determines through either a medical evaluation under the respiratory protection standard, or medical surveillance under the silica standard, that an employee has a medical condition that places the employee's health at increased risk if a negative pressure respirator is used, but the employee can use a powered air purifying respirator (PAPR), then the employer must provide a PAPR. No. For tasks that are not listed on Table 1, or where the employer does not fully and properly implement the engineering controls, work practices, and respiratory protection described on Table 1, the employer must comply with "alternative exposure control methods." 0000012786 00000 n No. 1926.1153(h)(6)(i). However, employers must properly select, use, maintain, and replace dust collection systems in order to ensure that they function as designed, e.g., by ensuring that the port and hose are not obstructed.
No. H\@E|E/g#TW g$/P| xO_5b sxtn~9uMMpp$]5jo.q~e\#>=mmKgrk)R_Kp2e|c>/e nTT[#IkaS*/V(IxJ~-yww;u) 15. 27. Therefore, employers of employees using handheld powered demolition hammers with bushing tools can follow Table 1 by fully and properly implementing the engineering controls, work practices, and respiratory protection specified in paragraph (c)(1)(x). 29 C.F.R. 1910.134(e)(1). However, an employer may rely on documentation from the employee that demonstrates the employee received a medical examination meeting the requirements of paragraph (h)(2) within the past three years and that contains the information described in paragraph (h)(6) (e.g., a copy of the written medical opinion sent to a prior employer and provided to the employee).
