The result of a first degree burn is charring and destruction of the cell producing layer of the skin.
False
(that’s third degree)
T/F
The preferred method of controlling serious bleeding is to apply a tourniquet.
False
What are 3 requirements for the use of eye and face protection?

- kept clean and in good repair
List 4 rules to be observed when selecting and wearing work clothing.
- be sure it fits
- avoid wearing jewelry
- don’t wear cuffed pants
- keep shirts tucked in
What are 4 symptoms of heat stroke?
- high body temp
- hot, red, dry skin
- strong and rapid pulse
- may be unconscious
When do safety standards require the use of hard hats?
in areas where there’s a danger of head injury from impact, falling objects, or from electrical shock and burns
How much dead weight must a lifeline or lanyard be able to support?
5,400 lbs
What is the maximum distance a safety net can be placed below a working surface?
25 ft below
What is the definition of first aid?
**KNOW
the immediate care given a victim of sudden illness or injury until a more skilled treatment is available.
List 3 basic electrical terms that should be understood by journeyworkers and apprentices
- current flow
- voltage
- resistance
What are 3 factors that determine dosage of electricity through the body?
- quantity
- path
- time
List 4 steps for preventing injury from a machine, tool, or work site
- train workers to be aware of hazards
- control hazards by enclosing
- use PPE to shield against them
- eliminate the hazard
List 5 safe practices that should be observed when using laser equipment
- only used by trained and qualified
- be turned off when not in use
- don’t aim it at anyone
- don’t operate in rain, snow, fog, dust
- when possible operate them above heads of others
What are 2 safety rules that must be observed by operators of electrically operated and gasoline driven abrasive cutting tools?
- Operator must be trained, competent person
- PPE must be worn
What causes an electrical shock?
as electricity travels from it’s source and returns to that source it makes a complete circuit. If anything comes in contact with the current-carrying wires and has lower resistance than the wire, the electricity follows the path of least resistance.
Define the term grounding
The electricity escapes the normal bounds of the insulated wire and follows a path of least resistance to the ground. If a grounded wire is available, the current will follow through that wire.
What is a ground fault circuit interrupter?
a protective device (circuit breaker) which monitors the amount of current flowing through the hot wire of an electrical load and compares it to the amount of current coming back through the neutral wire. It will stop the flow if it exceeds
How can current leakage be eliminated and the user of electrically operated tools be protected from this hazard?
inspect the tools and the grounding circuit to make sure the pathway from circuit to ground is continuous
What is the purpose of a foot switch on a pipe machine?
safety feature allowing the user to use both hands and stop the machine even if they should become entangled in the rotating parts
T/F
Screwdriver tips can be filed in order to remove nicks or square ends to proper shape
true
T/F
Wrenches should be pushed rather than pulled to minimize the chance of them slipping off the work.
false
T/F
Portable grinder motors should be equipped with a positive on-off switch
false
(must be equipped)
What are 3 factors that should be considered when selecting an impact or hammer struck tool?
- make sure heavy enough not to vibrate or spring when struck
- tool should be sharpened and proper length
- use w/a hammer of proper type, size, and weight
What are 2 special precautions that should be taken whenever force is applied to a pipe wrench?
- keep body weight balanced and under control
- make sure jaws are clean and have a positive grip
