MLSP LABORATORY SAFETY Flashcards
LAB SAFETY
Was enacted by the U.S. Congress in 1970
Main goal: provide all employees with a safe
work environment
Public Law 91-596
Authorize to conduct on-site
inspections to determine whether an
employer is complying with the
mandatory standards
Occupational safety and Health
Administration (OSHA)
Applies to all exposure to blood or
other potentially infectious materials
in any occupational setting
Bloodborne Pathogen Standard
Toxic and Hazardous Substances
regulations
Hazard Communication Standard
All patients are considered to be
possible carriers of blood-borne
pathogens
Instituted by CDC (1987)
Personnel should wear gloves at all
times when encountering moist body
substances.
BSI GUIDELINES
● Handwashing
● Gloves
● Mask, eye protection, and face shield
● Gown
● Patient care equipment
● Environmental control
● Linen
● Occupational health and blood-borne
pathogens
● Patient placement
STANDARD PRECAUTIONS
______ published the new Hazard
Communication Standard (Right to
Know Law).
(OSHA) Occupational safety and Health
Administration
Educate all employees, Maintain hazard warning labels on
containers received or filled on site.
CHEMICAL SAFETY HAZARD
COMMUNICATION
Major source of safety information for
employees who may use hazardous materials
MATERIAL SAFETY DATA SHEET
To address the shortcomings of the
Hazard Communication Standard
OSHA Laboratory Standard
Procedures describing how to protect
employees against teratogens,
carcinogens, and other toxic
chemicals must be described in the
plan
CHEMICAL HYGIENE PLAN
food wastes, yard wastes, etc. (green)
Biodegradable waste
paper, plastic, styrofoam, tin
cans, bottles, etc. (red)
Non-biodegradable/Recyclable
wastes
used/worn out rugs, ceramics, soiled
plastics, candy wrappers, etc. (blue)
Non-recyclable/residual wastes
used
fluorescent lamps/bulbs, batteries,
spray canisters, etc. (black)
Special/Hazardous Wastes
Provide safety information, training,
personal protective equipment, and
medical surveillance to employees.
Employer’s Responsibilities
No smoking, eating, and application of
cosmetics
GENERAL LABORATORY SAFETY PRACTICES
Proper use of PPE (should never be
worn outside the laboratory)
GENERAL LABORATORY SAFETY PRACTICES
All laboratories are required to have:
● Safety showers, (recommended that
safety showers deliver 30 to 50
gallons of water per minute at 20 to
50 psi)
● Eyewash stations,
● Fire extinguishers.
SAFETY EQUIPMENT
Absorb the spill with paper towels,
gauze pads, or tissue.

OTHER CHEMICAL HAZARDS AND SYMBOLS
☠☠☠☠💀💀☠☠☠
TOXIC/POISON
OTHER CHEMICAL HAZARDS AND SYMBOLS
✖✖✖✖
IRRITANT
which is the temperature
at which sufficient vapor is given off to
form an ignitable mixture with air
FLASH POINT
Certain gases, such as hydrogen, and
solids, such as paraffin
Flammable/Combustible Chemicals
poisons, irritants
and asphyxiants
Toxic Substances
- chemicals with a pH of <2
or > 12.5
Corrosive
flammable and combustible
Ignitable
Injurious to the skin or eyes by direct
contact (ACIDS)
Corrosive Chemicals
With molecular structures of high
reactivity
Reactive ChemicalS
Four Types of Ionizing Radiation
● Alpha Particles
● Beta Particles
● Electromagnetic Radiation)
● Neutron
Large and can travel only a very short
range in air
Alpha Particles
Smaller and they are negatively
charged electron
Beta Particles
Arise from spontaneous fission of some
isotopes and produced by atomic
reactors and accelerators
Neutrons
Composed of electromagnetic energy
and not composed of atomic particles
Gamma rays and X-rays
Differ from gamma rays only in the
origin of radiation
X-rays
No mass or charge but with great
penetrating ability
Gamma rays
Nuclear Regulatory Commission (NRC)
license is required if the total amount
of radioactive material exceeds a
certain level.
RADIATION SAFETY ENVIRONMENTAL
PROTECTION
represents the maximum allowable
exposure over an 8-hour work da
Time-Weighted Average (TLV-TWA)
represents the maximum
amount of allowable exposure for a
short period such as 15 minutes
Short-Term Exposure Limit
(TLV-STEL)
represents the concentration of an
agent that must never be exceeded
Ceiling Value Form (TLV-C)
CLASSIFICATION OF FIRES
ordinary combustible solid materials,
such as paper, wood, plastic, and fabric
Class A
CLASSIFICATION OF FIRES
flammable liquids/gases and
combustible petroleum products
CLASS B
CLASSIFICATION OF FIRES
energized electrical equipment
CLASS C
CLASSIFICATION OF FIRES
combustible/reactive metals, such as
magnesium, sodium, and potassium
CLASS D
Use only explosion-proof equipment
in hazardous atmospheres.
ELECTRICAL HAZARDS
Always follow the teacher’s directions
and only do lab work when a teacher
is present.
