materials, equipment, or debris

Construction sites are required to have X on hand

firefighting equipment

Classes of fire:

A: Wood, paper, cloth, plastic B: Grease, oil, chemicals C: Electrical chords, switches, wiring D: Combustible metals

Pass acronym:

Pull the pin Aim nozzle towards base of fire, stand 8 feet back Squeeze the handle to discharge the extinguisher Sweep the nozzle at the base of the fire

Excavation:

cut, cavity, trench, or depression made by removing earth

Two basic ways to shape an excavation:

Benches and simple slope

Benching:

the soil is excavated to form one or more steps or horizontal levels.

Simple slope or benched excavations more than X' must be designed by a registered engineer

20'

Always X before you dig

Call, local utilities must be contacted in order to determine location of existing underground utility lines

Proper slope depends on

soil type

Soil and equipment must be kept at least X' away from edge of excavation:

2 feet

Standing water must be X

pumped out of the excavation

Pneumatic tool:

a tool powered by compressed air

Most nailers and staplers operate on pressure of X to Y psi

60 to 120psi

Pneumatic Tools: When choosing a tool for a particular application, first determine the X, then find a tool that will Y

type and size of fastener needer Tool that will drive that fastener

How a nailer works: The trigger must be X and the Y

pulled and the nose piece must be pressed against the work piece before the tool can be fired.

Sequential Trip:

prevents the tool from firing unless the nose is pressed against the work piece before the trigger is pulled

Contact trip:

These nail guns do not have the safety feature of the sequential trip.

Nails do not always go in straight and may fishhook out one side of the wood. Keep your hand at least X" to one side of the impact point.

How do you maintain Pneumatic Tools?

Store the tool at room temp Lubricate the gaskets on a regular bases check the magazine which holds the fasteners as it may become clogged with dirt

What is a gasket?

piece of flexible material that keeps liquids or air from moving between parts of the tool.

An air compressor:

squeezes air into an air storage tank

Regulator:

valve that controls the air pressure reaching a nailer or a stapler.

Air-storage tank is usually a cylinder holding X to Y gallons of air

1 to 10

A pressure gauge measures X A line gauge measure Y

pressure in the tank pressure in the hose leading to the tool

Air compressor maintenance: Maintain the proper X level in the pump:

Oil

Air compressor maintenance: Release the X in the X at the end of each day. This helps to clear any Y in the tank.

Air in the air-storage Moisture

Air compressor maintenance: Air can be released by opening the X

drain petcocks

Air compressor maintenance: Clean the X filter on the pump regularly. This filter traps dirt, moisture and other contaminants.

air intake

Air compressor maintenance: The vibrations of an air compressor can X over time.

Loosen fittings

Air compressor maintenance: check the X

drive belt. Replace if worn or damaged

Air compressor maintenance: Check the X on the regulator periodically.

pressure gauge

Air Compressor Capacity: What determines the amount of air needed?

The rate, frequency of tool use and the type of nails or fasteners you are using.

Signs of low air supply:

air leakage, fasteners that are not set at the proper depth, skipped shots

volume of air in compressors is measured in

cfm (cubic feet per minute)

Air Hose: a hose supplying air to a tool should have a minimum working pressure rating that is X higher than the maximum pressure delivered by the compressor

50%

Air hoses: Do not use hoses larger than X feet

100'

Coordless tools are:

self contained and do not require a hose and air compressor.

How do coordless tools work:

internal combustion engine.

Maintaining Coordless Tools: Charge the X and replace the Y as needed. Be sure to use the correct Y. They are sometimes color-coded.

Battery Fuel cylinders

Maintaining Coordless Tools: Periodically clean the x

combustion chmber with aerosol degreaser Combustion chamber filter The nosepiece.

Maintaining Coordless Tools: Use what to remove asphalt

putty knife

Nails and Staples: Fasteners are often purchased from X because Y

the manufacturer because fasteners made by one manufacturer may not fit another.

Nailers must be loaded with nails that are X

collated

Collated fasteners:

arranged into strips or rolls, each one connected to a fastener on either side
