A central feature of the site is a free online planning tool Create A Plan to help contractors comply with the Written Exposure Control Plan requirement in the new standard. 0000007502 00000 n When respiratory protection is required, the contractor must comply with the Respiratory Protection standard (29 CFR 1910.134). As the National Institute for Occupational Safety and Healths (NIOSH) National Construction Center, CPWR and its consortium of academic research partners conduct research directed toward preventing construction worker injuries, illnesses and deaths, and translate the findings into practical tools and resources that contractors and workers can apply on construction sites. If the PLHCP recommends that the employee see a specialist, and the employee chooses to do so, the employer must make the examination by a specialist available to the employee within 30 days of receiving the opinion and the employees consent. The contractor may do air monitoring to develop objective data for certain tasks they routinely perform with the same equipment and controls under similar (or worse) conditions, or they can rely on similar data collected by a third party. 715 0 obj <>stream 0000008961 00000 n Operate and maintain machine to minimize dust emissions.

Where an employee performs more than one task on Table 1 during the course of a shift, and the total duration of all tasks combined is more than four hours, the required respiratory protection for each task is the respiratory protection specified for more than four hours per shift. hWmO8+[w;VHI;N!\TRBUzjcgl ND*%1QXbH$, For example, if you have an employee using a walk-behing-saw and another worker guiding the operator of the saw, then both would be considered engaged in the task.

Question: What are the requirements for protecting workers performing unrelated work nearby? The purpose of the medical surveillance clause in the new OSHA rule is three-fold: The standard requires construction employers to offer a medical examination to workers who will be required to wear a respirator under the new standard for 30 or more days per year.

See Table 1 for specific dust collection requirements by application. Announcement of the new standard prompted some in the industry to question the need for the standard since OSHA already had a permissible exposure level (PEL) for silica. Providing medical surveillance to employees exposed to silica on the job is an important step in ensuring that work is performed without endangering their health. Each worker that meets this criterion must be given the opportunity to have the examination required under the standard within 30 days after the initial work assignment of work unless the employee has received a medical examination that meets the requirements within the last three years. If the employee can demonstrate that they have already had an exam within the last three years, the employer does not have to offer another medical exam. 1 0 obj In addition to the requirements related to assessing and controlling exposures, all employers covered by the standard must have a written plan that identifies silica-generating tasks, the engineering controls and work practices that will be used for each task, respiratory protection (for exposures above the PEL), housekeeping practices used to limit exposures, and procedures that will be followed to restrict access to areas where silica-generating tasks will be performed. This section shall become effective June 23, 2016.

0000014772 00000 n Crystalline means that the oxygen and silicon atoms are arranged in a specific pattern. OSHA offers three methods an employer can choose from to demonstrate compliance and assess employee exposure: Table 1: a table of pre-defined tasks and specified control methods available in the market today, Performance or Objective Data: assess exposure by providing objective data proving the control method used reduces silica dust exposure below the permissible exposure level (50 g/m, Scheduled Air Monitoring program: assess exposure by implementing a scheduled air monitoring program to ensure employees are not exposed above 50 g/m, Employers are required to have a written exposure control plan, Medical surveillance (exams) must be offered for employees required by the standard to wear a respirator for 30 or more days per year.

The employer shall obtain a written opinion from the specialist within 30 days of the medical examination. If an Equipment/Task and Control method is not listed in Table 1 or a contractor chooses not to rely on Table 1, they can follow the options in section (d) Alternative exposure control methods to ensure that their employees are not exposed above the PEL. About CPWR. If an employer chooses to perform scheduled air monitoring for a task, they must follow the schedule outlined in the standard: Just like with objective data, the conditions of air sampling must losely resemble typical (or higher exposure) conditions. (k) Dates specifies the dates when employers must comply: This section includes Table 1 and online resources that are being updated regularly with new information and materials to help contractors comply with the standard and educate their employees: A.

Use dust collection system with close capture hood or shroud around drill bit with a low-flow water spray to wet the dust at the discharge point from the dust collector. During this course you will learn: how to identify potential silica exposure hazards, how to evaluate them and options for controlling them, including engineering controls, management controls and personal protective equipment..

A copy of the information provided to the PLHCPs and specialists.
Use tool with water delivery system that supplies a continuous stream or spray of water at the point of impact. Response: No. The final rule is written as two standards: one for construction and one for general industry and maritime. The construction standards PLHCP reporting requirements differ from other health standards. If the exposure monitoring indicates exposures above the PEL, additional monitoring must be repeated within 3 months. When used indoors or in an enclosed area, use a HEPA-filtered vacuum to remove loose dust in between passes. Response: No. Detecting the existence of health conditions that are either related to or may be exacerbated by silica exposure, permits medical providers to recommend and take appropriate intervention measures.
