Study Notes
Cutting Locks
- Cutting locks can be executed from a ladder, requiring only one hand to manage the torch after ignition.
- In cases of tampered locks, it's advisable to cut the U-shaped channel iron above and below the lock instead of trying to tamper with the lock itself.
- This approach preserves the integrity of the gate for quick re-securing after the emergency using a new padlock.
- Proper technique is critical when using saws on steel; blades should be engaged slowly to prevent sliding and potential injury.
- The American Lock 2000 gate lock features a concealed mechanism, making conventional tools ineffective against it.
- A metal-cutting power saw or torch is recommended for cutting this type of lock, ensuring correct cutting location at two-thirds the lock's height away from the keyway.
- Maintaining at least two saws on first-arriving units, with one fitted with a metal-cutting blade, is crucial to avoid delays in critical tasks.
Accessing Gates
- Once locks are removed, manually raised gates can be accessed by removing the gate key or retracting the sliding bolt to raise it slowly.
- For mechanical gates, utilize the hoisting chain for elevation, ensuring to engage the clutch if needed.
- Cutting the gate should be a last option due to high repair costs, longer time required, and incomplete access hindering ventilation and securing the premises.
- Indicators for cutting the gate include:
- Urgent rescues needed (trapped individuals).
- Heavy fire conditions requiring swift water application.
- Gates that are non-functional due to damage or electrical issues.
Cutting Techniques
- The inverted V or teepee cut allows for a rapid opening in emergencies; cuts must intersect at the top.
- This technique offers limited access and ventilation and poses challenges if a locked door is behind the gate.
- The three-cut method is preferred for unobserved conditions like wind tabs or recessed doors, ensuring optimal access by making diagonal cuts that meet at lower ends.
- Scrutinizing each cut's position is essential to ensure no hardware obstructs the removal of slats along frame edges.
Maintenance and Removal
- For wide doors, additional short cuts help in managing weight and facilitate slat removal.
- Striking at intervals of 5-6 feet can ease slat extraction and should be coordinated with team support.
- Use tools like locking pliers, a Halligan, or a flat-head axe to aid in removing slats.
- The goal is to clear a larger area while maintaining efficient cutting strategy to optimize access and ventilation.
