Safety Flashcards
What is (optimal) body mechanics?
Refers to the way in which the body moves and maintains balance while making effective use of its parts.
Describe a proper base of support
1) Feet 8-10 inches apart
2) 1 foot slightly forward
3) Balance weight on both feet
4) Point feet in the direction of movement
What division of the Department of Labor enforces and establishes safety standards for the workplace?
OSHA (The Occupational Safety and Health Administration)
What does the Occupational Exposure to Hazardous Chemicals standard state?
Employers must inform employees of all chemicals and hazards in the workplace.
Where is information about any hazardous product/chemical found in the workplace?
The corresponding Safety Data Sheet (SDS)
NFPA
National Fire Protection Association
What does the NFPA color code do?
Alerts user to health, fire, reactivity, and other specific hazards for a chemical
What does BLUE represent on the NFPA color code?
Health hazard
What does RED represent on the NFPA color code?
Fire hazard
What does WHITE represent in the NFPA color code?
Special hazard
What does YELLOW represent on the NFPA color code?
Reactivity hazard
What does the Bloodborne Pathogen Standard do?
Enforces mandates to protect workers from diseases caused by exposure to body fluids.
These can cause:
- hepatitis B (hepatitis B virus)
- hepatitis C (hepatitis C virus)
- AIDS (human immunodeficiency virus)
What is Ergonomics?
An applied science used to promote the safety and well-being of a person. This is done by ADAPTING THE ENVIRONMENT and using techniques to PREVENT INJURIES.
What are the three things a fire needs to start?
OXYGEN: Found in the air
FUEL: Any material that will burn
HEAT: Sparks, matches, flames, etc.
Class A fire extinguishers
Paper, cloth, plastic, and wood fires
Class B fire extinguishers
Flammable/combustible liquids (gasoline, oil, paint, grease, cooking fat)
Class C (non-conductive) fire extinguishers
Electrical fires (fuse boxes, appliances, wiring)
TURN OFF THE ELECTRICITY IF POSSIBLE
Class D fire extinguishers
Used on burning/combustible metals
Usually for a SPECIFIC type of metal
Water fire extinguishers
Contain pressurized waters
(Only to be used on CLASS A fires)
Carbon dioxide fire extinguishers
- Contains CO2 to smother the fire and remove the oxygen supply with a cloud of cool ice/snow
- Leaves powdery residue (similar to snow) that irritates the skin and is dangerous to the lungs
- Most effective on Class B and Class C fires (flammable liquids and electrical fires)
Dry chemical extinguishers
Contain chemicals to smother fires
BC fire extinguishers: Utilize potassium bicarbonate (KHCO3) or sodium bicarbonate (NaHCO3) to smother fires. Mildly corrosive, clean ASAP
ABC fire extinguishers: Contains monoammonium phosphate, which is a yellow powder that leaves a sticky residue that can damage appliances. (It’s the type in the dental office)
The chemicals found in said extinguishers are irritants
Used on class A, B, and C fires
Halon gas fire extinguishers
Uses halon gas, which interferes with the chemical reaction that occurs when fuel burns
Used on electrical equipment as it does not leave a residue (Class C fires)
Fire Emergency Plan?
(Hint: RACE)
R: Rescue anyone in danger
A: Activate the alarm
C: Contain the fire (close windows and doors, shut off equipment)
E: Extinguish or evacuate (depends on circumstance)
Fire extinguisher use?
(Hint: PASS)
P: Pull the pin
A: Aim extinguisher at near edge + bottom of fire
S: Squeeze handle
S: Sweep extinguisher from side to side
