SUSPENDED SCAFFOLD EMERGENCIES
Generally, there are three types of suspended scaffold emergencies that units respond to:
Unoccupied swinging scaffold.
Occupied stalled scaffold.
Occupied hanging or off-level scaffold.
All apparatus shall be kept clear of the danger area and parked in a safe location.
Enter the building from an entrance out of danger area, if possible.
UNOCCUPIED SWINGING SUSPENDED SCAFFOLD
Locate window nearest scaffold.
Secure scaffold with utility ropes to prevent movement.
Inspect exterior of the building for damaged or loose building/scaffold material that may fall.
Survey the roof to determine if the scaffold anchoring system has been compromised due to excessive movement.
At no time shall any member go out onto an unoccupied scaffold.
OCCUPIED STALLED SUSPENDED SCAFFOLD
(if they are stranded on windowless area of building, consider lowering handie-talkie from above).
Ascertain the following:
x Worker’s physical and mental state.
x If they know the cause of the stall and if they can correct the situation.
x If there are any co-workers inside the building who can lend assistance.
If the scaffold is in reach of a tower/aerial ladder, this may be used to effect removal.
OCCUPIED STALLED SUSPENDED SCAFFOLD
If hoist is overheated, allow it to cool for at least ____ minutes. Then have a worker push the reset button on the hoist.
15 minutes
PORTABLE POWER SAWS
Carbide tip blades will cut through
Aluminum Oxide blades (abrasive disc) will cut through
Silicon Carbide blades (abrasive disc) will cut through
Carbide tip blades will cut through gravel and tar covered roofs, wood flooring,light sheet metal and similar material.
Aluminum Oxide blades (abrasive disc) will cut through various types of steel,including auto bodies, metal security doors, metal window bars, etc.
Silicon Carbide blades (abrasive disc) will cut through concrete and othermasonry materials.
Return aluminum oxide or silicon carbide blades for replacement whenever:
A. Cracked or badly nicked.
B. Center hole wears out of round.
C. Blade is worn down to 8” diameter or less.
PORTABLE POWER SAWS
Fuel tank is sufficient for ___________________ of continuous operation.
Fuel tank is sufficient for 20 to 30 minutes of continuous operation. A gasoline oil mixture is used for engine fuel and lubrication. The tank has a special suction wick that permits saw operation regardless of position.
PORTABLE POWER SAWS
Belt Adjustment
Weekly at MUD
and after every cutting operation.
If MUD is canceled belt inspection and adjustment must be done when unit returns to quarters.
The saw should be placed out of service if blade continues to spin at a low idle.
For any major repairs return the saw to the Technical Service Division.
PORTABLE POWER SAWS
A physical communication system between the Guide Man and the Operator will be as follows:
One slap on the back of Operator ……………Stop Cut.
Two slaps on the back of Operator ………….Cut.
Three slaps on the back of Operator ………..Shut Down Saw.
PORTABLE POWER SAWS
Circle of Danger
During roof or floor cutting operations, everyone in the vicinity of a saw in operation shall observe, “as near as possible and practical, a 20 foot radius Circle of Danger.” This circle shall be measured in all directions FROM THE POINT WHERE THE BLADE OF THE SAW IS IN OPERATION.
Only the Officer, the Operator and the member designated as the guide may enter this circle.
This also applies while testing the saw in or around quarters, or using the saw at drills or training.
Chainsaw: A circle of danger of a radius of at least 10’ will be established before the commencement of cutting. The saw operator and control person will be the only personnel in this area during cutting. Officer is to monitor conditions and relay orders received from the officer in command. If possible, the officer is positioned as to permit visual contact with the control person.
PORTABLE POWER SAWS
OTHER THAN HORIZONTAL SURFACE
Whenever the saw is used on other than flat horizontal surface at foot level, the blade guard should be moved and secured to protect the Operator. It shall be used in this position only
Accordingly, whenever the saw is used on other than flat horizontal surface at foot level, the blade guard should be moved and secured to protect the Operator. It shall be used in this position only on the direct order and/or under the supervision of an officer.
PORTABLE POWER SAWS
When it has been determined that a roof opening is necessary to relieve fire conditions, cut shall be made at hot spot. The hot spot can be determined by:
A. Soft spots or tar bubbles.
B. Melting snow or ice.
C. On a wet roof, steam or dry area.
D. A sense of touch including soil pipes, vent pipes.
PORTABLE POWER SAWS
Other methods used to determine location of roof cut are:
A. Knowledge of fire location gathered on travel to roof.
B. Looking over roof edge.
C. Handie-talkie communications.
PORTABLE POWER SAWS
Sparks are a good indication that cut is on beam.
A 10’ hook brought to the roof of a taxpayer can be used efficiently to push down double ceilings, open returns, etc.
PORTABLE POWER SAWS
T. B. TOOLS 9, APPENDIX A DATA SHEET 1
List maintenance that can be performed by units in quarters:
A. Change spark plugs. B. Change the blade. C. Refuel the tank D. Change and adjust belt. E. Clean the exterior of the saw. F. Change the air filter.
COLOR CODING OF SAW BLADES
Silicone Carbide Blade (concrete cutting) shall be painted ___________.
YELLOW
Both sides of the blade should be painted to facilitate choice of proper blade.
Company Commander shall be responsible for proper color coding of blades. Use of yellow paint issued for safety markings is permissible.
Aluminum Oxide Blades (metal cutting) shall remain UNPAINTED.
Thermal Imaging Camera
Evolution 4000
The gauge resolution varies, depending on whether one or two batteries are installed:
When one battery is installed: the gauge is full if the battery is completely charged (approximately 1½ hours of camera run time).
When two batteries are installed: the gauge is full if both batteries are completely charged (approximately 3 hours of camera run time).
An on-screen low battery warning (a battery symbol within a triangle) flashes for 15 minutes of remaining battery life. 10 minutes for Argus
Thermal Imaging Camera
Evolution 4000
The Evolution 4000 has a heat-seeker indicator, which will indicate any portion of the screen in red:
When in high-sensitivity mode (low temperature): the portion of the scene which is above 392 degrees Fahrenheit.
When in low-sensitivity (El) mode (high temperature): the portion of the scene which is above 1112 degrees Fahrenheit.
The Evolution 4000 is equipped with a quick-temp indicator.
The on-screen operating quick-temp cross hairs (center) and vertical bar gauge (right) span temperatures from 100 to 1100 degrees Fahrenheit for objects located in the cross hairs.
Each tick on the bar gauge indicates 200 degrees Fahrenheit.
The Evolution 4000 is equipped with two nickel metal hydride batteries.
This camera utilizes a unique battery management system.
It can run from either one or two batteries.
With one battery, the camera will run for 1½ hours at 72 degrees Fahrenheit while saving the weight expense of a second battery. The battery can be placed in either battery slot.
For applications requiring a longer run time, two batteries can be installed, enabling the camera to run for 3 hours.
The charger unit requires approximately 2 hours to charge each battery.
If the Evolution 4000 does not meet the inspection as described in Section 3.1, or it is not operating properly, notify Tech Services for further instructions.
DO NOT SEND THE CAMERA WITH THE DIVISION MESSENGER
