This Manual shall apply to risk management practices for all potable and non-potable water supply systems during normal operation, when closing, during interruptions to normal operation, and when reopening building water systems in specific occupancy types. Section 4 shall apply to potable water systems, nonpotable water systems, and mechanical systems. Section 5 shall apply to potable water systems. Section 6 shall apply to nonpotable water systems. Section 7 shall apply to mechanical systems.
The purpose of this document is to establish methods to address the compliance of consumer products or materials with California Proposition 65 requirements. Product compliance is determined in accordance with this document and input from a product manufacturer and supplier. This document is intended to cover specific consumer materials or products that include:
The California Code of Regulations defines “consumer product” in § 25600.1. Definitions. as “any article, or component part thereof, including food, that is produced, distributed, or sold for the personal use, consumption or enjoyment of a consumer.” This Document addresses any potential exposures which may occur during the initial installation of a consumer product, whether the installation is by a professional or a consumer. This Document specifies some acceptable laboratory testing methods for various products/materials and exposure pathways. In addition, this document specifies methods which may be used to derive safe harbor levels, (No Significant Risk Levels (NSRLs) for cancer-causing chemicals and Maximum Allowable Dose Levels (MADLs) for chemicals causing reproductive toxicity), for chemicals specified on the Proposition 65 list for which no safe harbor levels have been derived. The Document is intended to be used by risk assessors and only applies to businesses with 10 or more employees.
The intent of this manual is to provide clarification of procedures for the design and approval of all gender toilet facilities not specifically covered in other parts of the Plumbing or Building Code.
This document will serve as a guide in assessing medical gas flow rates associated with varying pressures. Since the pandemic, the medical gas piping systems were stretched to their limits resulting in insufficient flow rates and pressures at patient outlets, due in part to undersized lines for elevated flow rates. The pandemic required facilities to alter their medical gas pressures for medical air and oxygen. This document will assist you in evaluating the medical gas systems and flow rates for temporary operations at elevated pressures.
For existing systems, this document provides guidance on how to determine the limitations of the line pressure increase and estimating the performance improvements using the pressure loss charts provided or by developing new charts. This document looks to provide additional concepts in using pressure regulators (refer to 2021 NFPA 99 5.1.3.5.7 in regard to multiple pressure requirements). Pressure regulators help to provide higher pressures in areas needing elevated pressure due to increased demand without having to increase pressure everywhere.
