Module 2 - Plumbing Safety

The percent of all accidental deaths in the construction industry caused by slips, trips, and falls is

15

A trench is a narrow excavation in which the depth is greater than the width and the width does not exceed

15 feet

For working conditions in a confined space to be considered safe, the oxygen level by volume must range between

19.5 and 23.5%

The distance that tools and equipment must be kept from the edge of a trench is

2 feet

The minimum amount of fresh air for each employee working underground required by OSHA is

200 ft.³ per minute

Safety requirements for underground work are covered in OSHA regulations outlined in

29 CFR 1926.800

When you wear a hard hat, the space between your head and the shell of the hard hat should be

1 inch

When inspecting an impact tool, an indication that the tool may be dangerous is

A mushroom head

Trench shield

A structure used in unshored trenches to protect workers from cave-ins

According to OSHA, a competent person is

A worker who can identify hazards and is authorized to take prompt corrective measures

The person responsible for creating an emergency action plan is

Accompany a pointed competent person or coordinator

Entry into a confined space begins when

Any part of your body passes through the entrance of a confined space

SCBA stands for self contained breathing blank

Apparatus

When working with or near this or hazardous mold, you must always wear a respirator

Asbestos

The most common type of Hazzard in a confined space is

Atmospheric

Too much or too little oxygen in a confined space creates this

Atmospheric hazard

When you are evacuating a building using an escape route, you should

Be prepared to use an alternate route if the main escape route is blocked

This is a method of cave-in protection that uses horizontal steps in an excavation

Benching

These tools have sharp edges

Bladed

And unbalanced stress in the soil causes this at the surface

Subsidence

If you are unsure about the emergency action plan at your job site, the person you should ask to explain it to you is your

Supervisor

These are written warnings to protect workers from energy sources

Tag out device

The sign or tag that is used to tell workers about potential hazards or unsafe practices is a

caution sign

One simple way to help ensure a safe work site is to

check the job site periodically and remove any clutter

The sign or tag that is used to tell workers that an immediate hazard exists and that specif precautions must be observed to avoid an accident is a(n)

danger sign

If your supervisor tells you evacuate the work site, you should

go to a safe location and wait until you are notified that conditions are safe

The two types of protection for openings in walls, floors, or the ground are

guards and covers

The color blue on a hazardous information label indicates a(n)

health hazard

The sign or tag that is used to tell workers about general information not related to safety is a(n)

informational sign

bladed hand tool is safest if it is

inspected and maintained regularly

You see a co-worker fooling around on the work site. Your course of action is to

tell your co-worker to stop

The MSDS is a fact sheet prepared by

the product's manufacturer or importer

OSHA's mission is to protect

the whole workplace environment

When welding, you must wear

tinted goggles or a hood

When job site surfaces are wet or icy, you should

wear shoes with cleats

Section IV of an MSDS

lists first-aid measures

To remove tools from scaffolding, it is best to

lower them to the ground using a rope

10. When working on a pitched roof, it is necessary to

periodically sweep the roof to remove dirt and debris

Walking and working surfaces that are located aboveground and sometimes over large equipment are called

platforms

The sign or tag that is used for general in- structions and suggestions related to safety measures is a(n)

safety sign

The highest level of respiratory protection is provided by

self-contained breathing apparatus

The most important things to look for on an MSDS are the_

specific hazards, personal protection requirements, handling procedures first-aid information, and the emergency- response telephone number

Material safety data sheet

Provides information about hazardous chemicals and materials

Subsidence can cause great stress on a trenches this

Shoring

Supporting the walls of an excavation to prevent their movement and collapse is called

Shoring

Always post a blank when using torches

Firewatch

Liquid fuel tools could most likely start a fire when

Flammable fuel vapor comes into contact with the hot tool

When air monitoring shows that an underground work area contains higher than minimum levels of methane or explosive gases, the work area is classified as a blank

Gassy operations

These are also called barricades and barriers

Guards

Freestanding scaffolding must be anchored with blank

Guy wires

Chisels, wedges, and punches are designed to be used with a

Hammer

The blank Requires employers to tell workers about hazardous materials on the job site

Hazcom standard

OSHA regulation specify the use of mechanical ventilation when

Natural ventilation is insufficient

You see construction workers cutting back the walls of an excavation at an angle to its floor. This is called

Sloping

When accidents happen at work, it is important to

Stay calm and tell your supervisor immediately

Air-purifying respirator cartridges absorb certain vapors from the air through

Charcoal

When preparing for a lock out/tag out, you should

Check the procedures to ensure that no changes have been made since the last lock out/tag out

Acetylene, butane, propane, and methane are considered these kinds of gases

Combustible

A blank has the training, experience, and authority to stop a job if it is not being done

Competent person

Ventilation is essential if you are working in

Confined spaces

Sound is measured in

DB

When locking in tagging motorized vehicles, you should also

Disconnect or disable the starting device

Electrocution is the most serious hazard of using of this

Electrically power tools

Stop valve is considered a this

Energy isolating device

Stop valves, disconnect switches, and circuit breakers are examples of

Energy isolating devices

These should be locked out and disconnected to make sure they are not powered on

Energy source

NFPA warning Diamond

Hey for color label placed on containers or doors to alert people to specific safety hazards on a product, room, or building

Non-permit required confined space

I can find work space that is free of any mechanical physical electrical or atmospheric hazards

The second step in the lock out/tag out sequence is to

Identify all authorized and affected person now

Hammer strikes are A common injury when using blank

Impact tools

Hypothermia

Is a condition that occurs when body temperature is too low

The person who must issue and sign an injury permit before anyone enters the confined space is the

Job site supervisor

Torches are considered this

Liquid fuel tools

Tags are placed on machinery and equipment during a blank procedure

Lock out

I'll stop valve, I disconnect, or a circuit breaker is placed in the off position during a blank

Lock out/tag out procedure

These can be used with key or combination locks

Lockout device

The two classifications for confined spaces are

Non-permit required and permit required

Safety standards are enforced by this

OSHA

OSHA stands for

Occupational Safety and Health Administration

Power tools

Operate using a power source

When an atmosphere has less than 19.5% oxygen, it is considered to be a this

Oxygen deficient atmosphere

I confined space containing too much oxygen is referred to as a blank

Oxygen enriched environment

Hazards are in a this can include chemical, mechanical, electrical, and physical hazards

Permit required confined space

Lockout and tag out devices are used to

Protect workers from all possible sources of energy

This restrains the movement of trench walls

Protective system

To protect workers from the collapse of an excavation wall in an unshored excavation, install an

Trench shield

The minimum number of communication methods that must be provided near shafts when hoisting or transferring personnel is

Two

A blade can be far more dangerous than a sharp blade if it is

dull

To obtain the best protection from a respira- tor, you must perform a positive and negative fit check

every time you wear it
