Study Notes
Fire Protection Systems in Construction
- Sprinkler systems are often the last to be installed; heads are placed only after ceilings are completed.
- Standpipe riser and outlets must advance to within two floors of the highest construction level, crucial for fire codes.
- Standpipes in cellars are used as drains and require manual shutoff during emergencies.
Standpipe Systems During Construction
- Standpipes are generally non-automatic dry systems in buildings under construction.
- Fire Department Connections (FDC) are essential water sources and should be clearly marked and accessible.
- Floor outlet valves are frequently left open during construction, which may lead to operational issues.
Water Testing Procedures
- First-arriving fire units should test the first-floor outlet; no water indicates potential issues in the system.
- Ascend through the building checking each outlet; an open riser top renders the system ineffective.
- Riser sectional valves can create zones for testing; closed valves render the system non-functional.
Structural Vulnerabilities
- Buildings under construction have a higher likelihood of collapse due to incomplete structures and absent flooring or roofing.
- Load-bearing walls are more stable than free-standing walls due to support from floors and ceilings.
- Missing fireproof coatings on steel components can lead to rapid thermal exposure and structural failure.
Steel Bracing Cables
- Temporary steel bracing cables provide essential support but are susceptible to fire exposure.
- Heavy fires threaten these cables, which can lead to extensive structural collapse if not cooled or evacuated promptly.
Post-Tensioned Concrete Concerns
- Tensioning cables in post-tensioned concrete are crucial for structural integrity but are vulnerable during construction phases.
- Fire during the tensioning period can lead to catastrophic collapse if steel is unprotected.
Collapse Risks in Construction
- Poured reinforced concrete structures are highly vulnerable to collapse when fresh concrete is curing, particularly in the first 48 hours.
- The weight of unhardened concrete is significant, increasing the risk of failure during this period.
Construction Safety Awareness
- Support structures like 4x4 wooden posts are essential while concrete cures; they prevent collapse during the critical period.
- After 48 hours, plywood formwork is stripped, but floors must remain braced for 16-20 days after pouring.
- Any fire in or above braced areas poses a high risk of structural collapse.
Evolving Construction Methods
- New construction techniques increasingly use aluminum posts and fiberglass forms; however, safety principles of required support during curing remain consistent.
- Disruption to supports can lead to catastrophic structural failures, especially during firefighting operations.
