Hard hat
What is a flammable liquid?
Flash point below 100•F and supports combustion
Define flash point
The temp at which a liquid produces enough amount of vapor to produce flame with source of ignition close to surface
Where do class C fires occur
Electrical equipment/facilities

What is a way to reduce chances I current reaching the heart or brain when working around live circuits?
Keep one hand in pocket
What precautions must you take when power that exceeds 300 volts is to remain on during testing
Qualified safety observer must be present
What items can you use for repair and adjustment of electrical items
Authorized by tech data or manufacturers guidelines
What should workbench stools be made of?
Wood, fiberglass, non conductive materials
Who can accomplish electrical repairs?
Competent qualified personnel
What type of cleaning solvent is authorized for cleaning electrical equipment?

When cleaning an electrical item, what must be installed to prevent energizing the item?
Proper lockout devices
What is an effective method of cleaning debris from circuit devices?
Vacuuming
When air cleaning, what is the max pressure you can use?
30 psi
What must you do prior to performing electrical testing?
Visually inspect all electrical equipment
What is the intent of performing an electrical inspection?
To detect obvious defects that could cause damage if powered
Bonding is different from founding in what respect?
It equalizes the static charge present, does not drain off or dissipate the charge
Name two types of grounding systems
System and equipment grounding
What is the purpose of an equipment ground?
Drains off any voltage built up in the units due to poor insulation or bare wires in them; ground wire prevents the operator from becoming the grounding conductor
