– Employees remain within the designated area
– The perimeter is delineated with a warning line consis7ng of a rope, wire, tape, or chain
Designated areas • (2) The employer must ensure each warning line:
– (i) Has a minimum breaking strength of 200 pounds; – (ii) Is installed so its lowest point, including sag, is not less than 34 inches and not more than 39 inches;
– (iii) Is supported in a manner that pulling on the line will not result in slack being taken up in adjacent sec7ons causing the line to fall below the limits
– (iv) Is clearly visible from a distance of 25 feet – (v) Is erected as close to the work area as the task permits; and
– (vi) Is erected not less than 6 feet (1.8 m) from the roof edge

– (1) When changes in the workplace render previous training obsolete or inadequate;
– (2) When changes in the types of fall protec7on systems or equipment to be used render previous training obsolete or inadequate; or
– (3) When inadequacies in an affected employee's knowledge or use of fall protec7on systems or equipment indicate that the employee no longer has the requisite understanding or skill necessary to use equipment or perform the job safely.
Effec7ve January 17, 2017 • Inspec7on and cer7fica7on of permanent building anchorages -‐ 1 year;

OSHA’s Respirable Crystalline Silica Rule Exposures from chipping, cuong, sawing, drilling, grinding, sanding, and crushing concrete, brick, block, rock and stone
22
Final Rule Published on March 25, 2016
Construc7on employers must comply by June 23, 2017 General Industry employers must comply by June 23, 2018, except :
Employers must comply with the ac7on level trigger for medical surveillance by June 23, 2020. (The PEL is the trigger from June 23, 2018 through June 23, 2020.)
23
Scope of Coverage • Three forms of silica:
– quartz, – cristobalite – tridymite
• All occupa7onal exposures to respirable crystalline silica are covered
Permissible Exposure Limit (PEL)
• PEL = 50 µg/m3 as an 8-‐Hour TWA
• Ac7on Level = 25 µg/m3 as an 8-‐Hour TWA
24
Scheduled Monitoring Op7on • Prescribed schedule for ini7al and periodic personal monitoring
• If monitoring indicates: • Ini7al below the AL: no addi7onal monitoring • Above the AL: repeat within 6 months • Above the PEL: repeat within 3 months • When two consecu7ve non-‐ini7al results, taken 7 or more days apart, are below the AL, monitoring can be discon7nued
• Reassess if circumstances change
