Ventilation for Acceptable Indoor Air Quality

Developed by American Society of Heating, Refrigerating, and Air-Conditioning Engineers, ASHRAE 62.1 was published in the summer of 2010.

ANSI/ASHRAE Standard 62.1-2010 supersedes Standard 62.1-2007. It is ASHRAE’s standard for indoor air quality for commercial buildings. The 2010 revision adds new minimum filtration/air-cleaning requirements, minimum requirements for when ventilation systems must be operated, and a Natural Ventilation Procedure. Other revisions include a more robust IAQ procedure, demand-controlled ventilation system design requirements, requirements for separation of intakes and exhausts, and ventilation rates and occupancy categories.

NFPA (Fire) 72

In the most extensive Code revision since 1993, the 2010 NFPA 72′s scope and organization have expanded beyond the core focus on fire alarm systems to also include requirements for mass notification systems used for weather emergencies; terrorist events; biological, chemical, and nuclear emergencies; and other threats. This wider coverage is reflected in a new Code title: National Fire Alarm and Signaling Code.

New chapter on Emergency Communications Systems responds to today’s concerns.

In addition to updated rules for in-building fire emergency voice/alarm communications systems, this new chapter includes first-time provisions for:

• Risk analysis requirements for the design of mass notification systems (MNS)
• In-building MNS
• Wide-area MNS for locations such as college campuses and military bases
• Distributed recipient MNS to communicate with targeted individuals or groups
• In-building radio enhancement systems
• Area of refuge for two-way emergency communications systems

Other major revisions and additions that increase protection affect:

• Circuits and pathways — A new chapter combines existing and new requirements and consolidates basic wiring rules and circuit performance into one location.
• Voice intelligibility — Revised installation and testing provisions plus an extensive new Annex with detailed guidance for testing
• Signaling for the deaf and hard of hearing — Improved safety in sleeping areas includes new rules that mandate low-frequency signaling for those with mild to severe hearing loss, and tactile as well as visible signaling for those with profound hearing loss.
• Smoke detector placement — Updated spacing and placement requirements for level beamed ceilings and new spacing requirements for sloped beamed ceilings

Risk-Based Inspection, Second Edition (Recommended Practice)

API Recommended Practice 580 provides users with the basic elements for developing, implementing and maintaining a risk-based inspection (RBI) program. It provides guidance to owners, operators, and designers of pressure-containing equipment for developing and implementing an inspection program. These guidelines include means for assessing an inspection program and its plan. The approach emphasizes safe and reliable operation through risk-prioritized inspection. A spectrum of complementary risk analysis approaches (qualitative through fully-quantitative) can be considered as part of the inspection planning process. RBI guideline issues covered include an introduction to the concepts and principles of risk-based inspection for risk management; and individual sections that describe the steps in applying these principles within the framework of the RBI process include:

• understanding the design premise;
• planning the RBI assessment;
• data and information collection;
• identifying damage mechanisms and failure modes;
• assessing probability of failure;
• assessing consequence of failure;
• risk determination, assessment and management;
• risk management with inspection activities and process control;
• other risk mitigation activities;
• reassessment and updating;
• roles, responsibilities, training and qualifications;
• documentation and record-keeping.

Inspection of Pressure-relieving Devices, Third Edition (Recommended Practice)

API Recommended Practice 576 describes the inspection and repair practices for automatic pressure-relieving devices commonly used in the oil and petrochemical industries. As a guide to the inspection and repair of these devices in the user’s plant, it is intended to ensure their proper performance. This publication covers such automatic devices as pressure-relief valves, pilot-operated pressure-relief valves, rupture disks, and weight-loaded pressure-vacuum vents.

The scope of this RP includes the inspection and repair of automatic pressure-relieving devices commonly used in the oil and petrochemical industry. This publication does not cover weak seams or sections in tanks, explosion doors, fusible plugs, control valves, and other devices that either depend on an external source of power for operation or are manually operated. Inspections and tests made at manufacturers’ plants, which are usually covered by codes or purchase specifications, are not covered by this publication.

This publication does not cover training requirements for mechanics involved in the inspection and repair of pressure-relieving devices. Those seeking these requirements should see API 510, which gives the requirements for a quality control system and specifies that the repair organization maintain and document a training program ensuring that personnel are qualified.
