How many square feet of decking is required for a CDZ?
Unsecured decking in a CDZ shall not exceed 3,000 square feet (914.4 m 2 ).
How wide is a CDZ?
The boundaries of a CDZ shall be designated and clearly marked. The CDZ shall not be more than 90 feet (27.4 m) wide and 90 (27.4 m) feet deep from any leading edge.
Who can access CDZ?
Access to a CDZ shall be limited to only those employees engaged in leading edge work.
What is a CDZ boundary?
Answer: Section 1926.760 (c) (3) requires that the boundaries of the CDZ be marked "by the use of control lines or the equivalent." In a CDZ, the control line restricts access by visually warning employees of an unprotected area (66 FR 5247). Control lines can be made of rope, wire, tape, or other equivalent materials, but they must clearly designate the CDZ. Examples of other acceptable methods would be a perimeter wall, guardrail system, or even a restraint system rigged so that non-leading edge workers could not access the area. In contrast, a line painted on the floor would not be considered to be equivalent to control lines since it would be less visible than a control line .
How wide is a CDZ?
The CDZ shall not be more than 90 feet (27.4 m) wide and 90 feet (27.4 m) deep from any leading edge. The CDZ shall be marked by the use of control lines or the equivalent. Examples of acceptable procedures for demarcating CDZs can be found in Appendix D to this subpart. [Emphasis added.]
What is the second purpose of fall protection?
The second purpose is to limit the size of the area where workers are unprotected by conventional fall protection.

What is a controlled access zone?
A controlled access zone is a safety measure for workers at heights where guardrails or fall arrest equipment are not able to be used. OSHA requires employers to implement fall protection measures for employees working at heights of six feet or more. A controlled access zone is used to prevent non-essential workers or personnel from entering a particular area of the job site. Let’s take a look at what controlled access zones are, and how they should be implemented in compliance with OSHA regulations.
What is the difference between a warning line and a controlled access zone?
Warning line systems are generally erected to protect all workers on a job site, whereas a controlled access zone is used to control which employees have access to specific areas on a job site
How far from an unprotected edge must a controlled access zone be?
Lines marking out the controlled access zone must be set up between 10 and 15 feet from any unprotected edge. Lines must be set up to create an enclosing perimeter. Workers are not allowed inside the controlled access zone unless they are actively engaged in bricklaying or masonry activities.
What is required to be marked in a controlled access zone?
A controlled access zone must be marked clearly using tape, wire, or rope. Employers are expected to adhere to all OSHA requirements (see our checklist above).
What is a guardrail?
The guardrail is used to cordon off the area and block non-essential workers from entering. A safety monitor supervises the area and controls who is allowed through the gate. A controlled access zone is most typically used for jobs requiring workers to be on a leading edge. Examples of this might include some types of masonry and bricklaying.
How high should a safety monitor be?
The lowest point (including sagging) must be at least 39 inches above the working area and no higher than 45 inches. Control lines are required to withstand at least 200 pounds of weight. The safety monitor must be a competent individual who does not have conflicting responsibilities on the job site.
What is a warning line?
By definition, a warning line system is any type of barrier set up on a rooftop that warns workers of an unprotected edge. This also designates a working area that does not require workers to use guardrails, belts or safety net systems.
