7 Slide 7 What Is Respirable Crystalline Silica? Important definitions PEL Permissible Exposure Limit, a limit established by OSHA is a legal limit in the United States for exposure of an employee to a chemical substance or physical agent such as loud noise.... For chemicals, the chemical regulation is usually expressed in parts per million (ppm), or sometimes in milligrams per cubic meter (mg/m 3 ). TWA Time Weighted Average is used to calculate a worker s daily exposure to a hazardous substance (such as chemicals, dusts, fumes, mists, gases or vapors) or agent (such as occupational noise), averaged to an 8-hour workday, taking into account the average levels of the substance or agent and the time spent in the area.

8 Slide 8 What Is Respirable Crystalline Silica? Important definitions Threshold Limit Value, TLV Action Level Work Exposure Plan Engineering and Workplace Controls Objective Data Monitoring Specified Exposure Control Methods Respirable Crystalline Silica

9 Slide 9 What Is Respirable Crystalline Silica? Important definitions µg/m 3 is micrograms per cubic meter or the amount of dust in the ambient air In this case, respirable crystalline silica

10 Slide 10 Micrograms Micron About the size of a single particle of fine milled flour Gram Small metric unit of weight measure - gold is measured in grams 1,000,000 micrograms (ug) in 1 gram Permissible exposure limit (PEL) for respirable Crystalline Silica is 50 micrograms per cubic meter of air, averaged over an 8 hour shift Measured by special analytical instruments Photo courtesy of The University of Waikato, Hamilton, New Zealand

14 Slide 14 What Are the Health Effects? Timeline 1970s - Original level set at 250 µg/m 3 For construction Based on calculations Proved obsolete by respirable mass (gravimetric) sampling World Health Organization announced material as a possible human carcinogen OSHA attempted to drop PEL for construction Litigation ensued

15 Slide 15 What Are the Health Effects? Timeline OSHA stepped up enforcement OSHA established long-term goal of updating standard American Conference of Governmental Industrial Hygienists recommends TLV for respirable crystalline silica to 50 µg/m 3

16 Slide 16 What Are the Health Effects? Exposure to respirable crystalline silica can cause With exposure levels set with old standard for illness was unacceptably too high Greater than 1 death for 1,000 workers 45 years of work exposure At old levels there was a risk of Increased risk of lung cancer Silicosis mortality Morbidity (Disease) Increased risk of death from other nonmalignant respiratory disease Chronic Obstructive Pulmonary Disease (COPD)

17 Slide 17 What Are the Health Effects? Exposure to respirable crystalline silica can cause Silicosis a serious lung disease caused by the inhalation of crystalline silica dust; inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs. Lung cancer Other non-malignant respiratory disease COPD, a group of lung diseases that block air passages and makes it hard to breathe Renal and autoimmune effects Immune system attacks and damages its own tissue and organs, including the kidneys Kidney disease Cardiovascular disease

18 Slide 18 What Are the Health Effects? How much exposure is too much? PEL - Significant risk for construction at PELs greater than 250 µg/m 3 Greater than 1 death/1,000 workers for a working life of 45 years Reducing allowable exposure to 50 µg/m 3 greatly reduced risk Where were the PELs over 250?

19 Slide 19 What Is the New OSHA Silica Standard? New Standard reduces the allowable PEL The ruling established a new PEL for respirable crystalline Silica New PEL is 50 µg/m 3 Includes provisions to protect employees by including the following requirements: Exposure assessment Methods for controlling exposure Respiratory protection Medical surveillance Hazard communications Recordkeeping

46 Slide 46 What Is OSHA s Hazard Communication Standard? In order to ensure chemical safety in the workplace, information about the identities and hazards of the chemicals must be available and understandable to workers. OSHA's Hazard Communication Standard requires the development and dissemination of such information. Rulemaking Background Hazard Classification Provides specific criteria for classification of health and physical hazards, as well as classification of mixtures Labels Chemical manufacturers and importers will be required to provide a label that includes a harmonized signal word, pictogram and hazard statement for each hazard class and category. Precautionary statements must also be provided.

47 Slide 47 What Is OSHA s Hazard Communication Standard? Labels Chemical manufacturers and importers will be required to provide a label that includes a harmonized signal word, pictogram and hazard statement for each hazard class and category. Precautionary statements must also be provided. Safety Data Sheets Will now have a specified 16-section format Information and Training Employers are required to train workers by Dec. 1, 2013, on the new labels elements and safety data sheets format to facilitate recognition and understanding. Maintaining Disclosure of exposure limits (TLVs)

48 Slide 48 What Is OSHA s Hazard Communication Standard? Steps to an Effective Hazard Communication Program Step 1. Learn the Standard/Identify Responsible Staff. Obtain a copy of OSHA s Hazard Communication Standard. Become familiar with its provisions. Make sure that someone has primary responsibility for coordinating implementation. Identify staff for particular activities (e.g., training). Step 2. Prepare and Implement a Written Hazard Communication Program. Prepare a written plan to indicate how hazard communication will be addressed in your facility. Prepare a list or inventory of all hazardous chemicals in the workplace. Step 3. Ensure Containers Are Labeled. Keep labels on shipped containers. Label workplace containers where required.

49 Slide 49 What Is OSHA s Hazard Communication Standard? Steps to an Effective Hazard Communication Program Step 4. Maintain Safety Data Sheets (SDSs). Maintain safety data sheets for each hazardous chemical in the workplace. Ensure that safety data sheets are readily accessible to employees. Step 5. Inform and Train Employees. Train employees on the hazardous chemicals in their work area before initial assignment and when new hazards are introduced. Include the requirements of the standard, hazards of chemicals, appropriate protective measures, and where and how to obtain additional information.

50 Slide 50 What Is OSHA s Hazard Communication Standard? Steps to an Effective Hazard Communication Program Step 6. Evaluate and Reassess Your Program. Review your hazard communication program periodically to make sure that it is still working and meeting its objectives. Revise your program as appropriate to address changed conditions in the workplace (e.g., new chemicals, new hazards, etc.). Source:
