Study Notes

Life Safety Overview

Hazards represent potential threats of unwanted events; risks quantify the likelihood of these events occurring.
Building design must include safety factors to mitigate risks during normal and emergency conditions.
Factors influencing safety factor magnitude include building importance, potential injury/property loss, and uncertainty of loads or component behavior.

Wind Protection

Wind pressures are positive when pushing components inward and negative when causing uplift or suction.
Common wind-induced failure modes for buildings include overturning, sliding, component separation, excessive sway, and structural collapse.
Lightweight and open-sided buildings are particularly vulnerable to uplift failure.

Earthquake Protection

Buildings should withstand minor earthquakes without damage; major earthquakes should not lead to collapse.
Soil liquefaction results from saturated soil losing strength and stiffness.
Landslides involve the movement of earth, rock, or debris down slopes.

Earthquake Characteristics

Earthquakes release energy from sudden movements, with the hypocenter representing the underground origin and the epicenter directly above it on the surface.
Seismic severity is often assessed using the Modified Mercalli and Richter scales.

Water Protection Measures

Floodproofing and waterproofing are essential to safeguard buildings from water damage due to floods, heavy rain, plumbing leaks, or storm surges.
Effective roof drainage systems help manage water.

Fire Protection Strategies

Fire protection encompasses life safety and property protection; complete safety from fire is unattainable.
Fire protection standards are guided by the National Fire Protection Association (NFPA) and Underwriters Laboratories (UL).
Classes of fire suppression systems include automatic sprinklers and standpipes.
Proper ventilation facilities are necessary alongside automatic systems for smoke and heat management.

Emergency Egress Protocols

Exit facilities must allow occupants to reach exits quickly and safely, with accessible paths for individuals with disabilities.
Building codes define exits as safe, unobstructed routes from the building interior to a safe external area.
Acceptable means of egress include exit passageways, doors, horizontal exits, interior and exterior stairs, smokeproof towers, escalators, and moving walks.

Construction Safety Regulations

Compliance with the Department of Labor and Employment (DOLE) standards is mandatory for construction safety management, guided by RA 11058.
Unsafe acts include unauthorized equipment operation, failure to secure warnings, the use of defective tools, and improper safety practices.
Unsafe conditions encompass defective equipment, poor housekeeping, exposure to hazards, and inadequate warning systems.

Construction Hazards

Key construction hazards include falling objects, open excavations, welding operations, dust and dirt exposure, temporary electrical wirings, and overhead electrical lines.

Lightning Protection

Lightning poses a threat of destruction during thunderstorms; specialized electrical systems are vital for protection.
Objectives of lightning protection include safeguarding lives, preventing property damage, and ensuring services like electrical and communication systems remain operational.
