14. OSHA 29CFR1926, Subpart AA, Section 1200-1213, “Confined Spaces in Construction”May 4, 2015, OSHA issued a new standard for construction work in confined spaces, which became effective August 3, 2015.Previously, the only requirement for confined spaces in construction was training. OSHA concluded that this was inadequate.According to osha….14
15. OSHA Fact Sheet 3914 states:“However, the vast majority of the standard’s requirements only apply to permit-required confined spaces, and attics, basements, and crawl spaces in a residential home — three common spaces – will not typically trigger these requirements.”According to osha….154 “characteristics” – Hazardous atmosphere, Engulfment, Entrapment and other serious hazards.
16. DO A HAZARD ASSESSMENT!Confined space Hazard assessment16
17. Confined space Hazard assessment17Is it a non-permit confined space?
18. Confined space Hazard assessment18
19. “Hazardous Atmosphere” – “acute hazard”; immediate danger of death or impairment that could impede the employee's ability to exit the confined space without assistance.Another key point19The ability of an entrant to exit a confined space without assistance.
20. Does the presence of electrical equipment in an attic or crawl space make the space a permit-required confined space?Confined space quiz….20No. Only if there is a hazard associated with the electrical equipment, such as an exposed live conductor, and the exposure could impede the entrant’s ability to exit the space without assistance.
21. Does the presence of a fall hazard alone in an attic make it a permit-required confined space?No. A fall hazard in an attic – such as falling through the drywall of the attic – could cause a serious injury. However, fall hazards within an attic would not generally impede the ability of an entrant to exit the space without assistance and therefore would not trigger the permit-required confined space requirements.Confined space quiz….21
22. Does the presence of asbestos in an attic make it a permit-required confined space?No. Asbestos would not trigger the permit-required confined space requirements of the Standard. However, if asbestos were present in an attic, an employer would need to follow any applicable requirements of OSHA's asbestos standards.Confined space quiz….22
23. Would heat in an attic make it a permit-required confined space?Maybe…. Extreme heat can be considered a serious physical hazard that triggers the permit-process. How hot it must be to trigger has not been quantified, but it must be so extreme that it could potentially impede the ability to exit the attic without assistance. Factors:Temperature of the space while work is performed, Nature and duration of the tasks performed in the heat, and Whether the entrant is acclimatized to work in extreme heat. Note, measures to control the heat (e.g. a fan) will be considered by the OSHA in determining whether a serious hazard exists in the first instance.Confined space quiz….23
24. Confined Space Attic?Confined space quiz….24
25. 25What if you wanted to go into a permit-required confined space?
26. “Alternate Procedures”Only hazard is an actual or potential hazardous atmosphere.Continuous forced air ventilation alone is sufficient for safe entry.In the event the ventilation system stops working, entrants can exit the space safely.Monitoring and supporting inspection data developed. Continuous monitoring of the atmosphere / periodic monitoring.Permit-required Confined space26Develop and follow a Permit-Required Confined Space Program.

28. silica
29. What is silica?29Chemical compound – an oxide of silicon; formula SiO2.Most commonly found in nature as quartz, but makes up sand and glass (major component of rocks and mountains).One of the most complex and most abundant families of materials.Also produced synthetically.OOSi
30. Where do you find it?30ConcreteBrickBlockMortarGlassStone countertopsCeramicsJoint CompoundCutting, sawing, drilling, crushingJackhammeringSandblastingFrackingDemolitionMasonry workMiningTunneling
31. Silica – the risks31Respirable crystalline silica – dust at least 100 times smaller than ordinary sand.OSHA estimates that over two million workers are exposed to respirable crystalline silica.Enters deep into lungs, can cause problems – scarring, lesions
32. Silica – the risks32Lung cancer & other respiratory diseases (chronic obstructive pulmonary disease – COPD), & even kidney disease.Silicosis – “Miner's Phthisis,” “Grinder's Asthma,” “Potter's Rot”Symptoms:Shortness of breath,Cough,Fatigue,Loss of appetite,Chest pain, Fever, and Cyanosis (bluish skin). Often misdiagnosed as pulmonary edema (fluid in the lungs), pneumonia, or tuberculosis.
33. silicosis33
34. Currently, no treatment or therapy for Silicosis; remove from exposure.Damage is irreversible.Higher risk of contracting tuberculosis.Silica – the risks34
35. OSHA’s permissible exposure limits (PELs) for crystalline silica were 40 years old…….Osha & silica35
36. Since then, the U.S. National Toxicology Program, the International Agency for Research on Cancer, and the National Institute for Occupational Safety and Health (NIOSH) have all identified respirable crystalline silica as a human carcinogen.OSHA AND SILICa36Old OSHA PEL:8-hour time-weighted average exposure to respirable crystalline silica dust of 100 μg/m3 (micrograms per cubic meter).
37. Does the standard apply to you?Osha and silica37As of June 23, 2016:New OSHA PEL:8-hour time-weighted average exposure to respirable crystalline silica dust of 50 μg/m3 (micrograms per cubic meter).
38. “Could employees be exposed to respirable crystalline silica at or above 25 μg/m3 as an 8-hour TWA under any foreseeable conditions, including the failure of engineering controls, while performing construction activities?” (action level)“Some employees in the construction sector perform tasks involving occasional, brief exposures to respirable crystalline silica that are incidental to their primary work. “Osha and silica38
39. “Where employees perform tasks that involve exposure to respirable crystalline silica for a very short period of time, exposures for many tasks will be below 25 μg/m3 as an 8-hour TWA.““For example, for hole drillers using hand-held drills, if the duration of exposure is 15 minutes or less, the 8-hour TWA exposure can reasonably be anticipated to remain under the 25 μg/m3 threshold (assuming no exposure for the remainder of the shift), and the standard would not apply.”OSHA’s “Small Entity Compliance Guide”Osha and silica39
40. “Where employees perform tasks that involve exposure to respirable crystalline silica for a very short period of time, exposures for many tasks will be below 25 μg/m3 as an 8-hour TWA.““For example, for hole drillers using hand-held drills, if the duration of exposure is 15 minutes or less, the 8-hour TWA exposure can reasonably be anticipated to remain under the 25 μg/m3 threshold (assuming no exposure for the remainder of the shift), and the standard would not apply.”OSHA’s “Small Entity Compliance Guide”Osha and silica40How do we prove?Industry standard?
41. If the Silica standard applies to your work:Either use the Specified Control Methods (Table 1), orUse Alternative Exposure Control MethodsOsha and silica41Enforcement delayed until Sept 23, 2017….
42. Specified control method (table 1):42
43. Determine levels of respirable dust;Limit exposure to 50 micrograms per cubic meter (8-hour twa);Use engineering and work practice controls; andKeep records of employee exposures.Alternative exposure control methods43
44. Regardless of method, all employers covered by the standard must:Provide respiratory protection when required;Restrict housekeeping practices that expose employees to respirable crystalline silica where feasible alternatives are available;Establish and implement a written exposure control plan, including designating a competent person;Offer medical exams to employees who will be required to wear a respirator under the standard for 30 or more days a year;Communicate hazards and train employees; andKeep records of any medical examinations.Osha and silica44
