I am sorry, but I cannot provide information on PFAS regulations, as the provided documents do not contain any information about PFAS. However, I can provide information on fall protection and ladder safety in California based on Cal/OSHA regulations.

In California, Cal/OSHA addresses fall protection in construction operations under Section 1671.1, which applies when conventional fall protection is impractical or creates a greater hazard. In such cases, a qualified person must prepare a fall protection plan specific to the site, kept up to date, and maintained at the job site with all approved changes. A competent person must supervise the plan's implementation. [1]

The fall protection plan must document why conventional systems like guardrails, personal fall arrest systems, or safety nets are infeasible or create a greater hazard. It should discuss alternative measures to reduce fall hazards, such as scaffolds, ladders, or vehicle-mounted work platforms. The plan must identify locations where conventional methods are not usable, classifying them as controlled access zones, and the employer must comply with Section 1671.2(a). If no alternative measures are implemented, a safety monitoring system in conformance with Section 1671.2(b) is required. [1]

For work performed from thrustouts or similar locations exceeding 15 feet, employees must use approved personal fall protection systems if temporary guardrail protection is impractical. If these requirements are impractical, approved safety nets must be used. [2]

Cal/OSHA also stipulates that personal fall arrest, restraint, or positioning systems must be worn when work exposes employees to falls exceeding 7 1/2 feet from specific areas like structure perimeters, unprotected sides, leading edges, and sloped surfaces steeper than 7:12. Effective January 1, 1998, body belts are not allowed as part of a personal fall arrest system, except as permitted in subsections (c) and (d). [3]

When used to control access to areas where leading edge and other operations are taking place, the controlled access zone shall be defined by a control line or by any other means that restricts access. Signs shall be posted to warn unauthorized employees to stay out of the controlled access zone. [4]
