Bioenvironmental engineering personnel at local medical facility
What is the best basic protection against atmospheric contaminants?
Good ventilation
What conditions determine whether goggles or a face shield should be worn?
Need more visibility, might fog, entire face needs protection
What other head protection would you normally use?
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
Fire symbol A
Wood paper cloth trash, can be extinguished by water effectively
Fire symbol B
Gas fuels solvents, dilute or eliminate oxygen
Fire symbol C
Electrical equipment, must be nonconductors of electricity
Fire symbol D

.001 ampere
Very painful shock could cause unconsciousness followed by death
.025 to .050
List the conditions where all voltages are potentially dangerous
Excessive humidity, wet damp areas, exposed connectors
State the purpose of electrical safety
Prevent electrocution or the setting off of combustible/explosive materials
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?
Only approved
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
What is the primary hazard involved w fiber optics systems?
Damage to unprotected eyes
What is a secondary hazard associated w fiber optics systems?
Particles formed by broken pieces of fiber
What are the primary hazards that you must consider when handling explosives?
Toxicity, sensitivity, fragmentation, forward firing, human factor
Name three factors that influence the velocity and distance of explosive fragments
Type of explosive, type of container, velocity of detonation
What hazard do forward firing munitions present?
Directional response and potentially long range impact if activated inadvertently
What technique can be used to prevent an explosive train?
Proper grounding/bonding
Why must you store explosive items on a dunnage?
To keep off ground or floor
How should explosive items be stored?
In original container, in dry well ventilated place protected from sun rays and excessive heat
What clothing materials are high static producers?
Polyester, nylon, rayon, silk, wool
What is the rule for putting on or removing clothing while engaged in explosive operations?
Step out of immediate area, remove garment, ground themselves, reenter
What is the first rule you must follow when planning an explosive operation?
Min people, min explosives, min time
What must the analysis of determining explosive limits include?
Operation timing, transport methods, size of items, chemicals and physical characteristics
What DOD hazard class includes ammunitions and explosives?
Class 1
Class 1 division 1 explosives produce what hazards?
Blast hazard, mass detonating
Class 1 division 2 explosives produce what hazards?
Fragmentation and blast
What items are classified as class 1 division 4
