LESSON 2: LABORATORY SAFETY Flashcards
For chemical safety, what is proper thing to do?
➢ All chemicals be identified
➢ Proper labeling is a must indicating
health risks(carcinogen, mutagen,
teratogen) and hazard class (corrosive,
poison, flammable, oxidizing)
➢ Hazardous chemicals must be
inventoried annually
All laboratories must have a file of
every chemical they use and with
corresponding MATERIAL
SAFETY DATA SHEET (MSDS)
FUME HOODS are provided to
prevent inhalation of toxic fumes
✓ Protection against chemical odor by
exhausting air to the outside
MSDSs includes:
✓ Substance name
✓ Name, address and telephone number of
manufacturer
✓ Hazardous ingredient
✓ Physical and chemical properties
✓ Fire and explosion data
✓ Toxicity
✓ Health effects and first aid
✓ Stability and reactivity
✓ Shipping data
✓ Spill, leak and disposal procedures
✓ Personal protective equipment
✓ Handling and storage
What should we do for fire safety?
➢ Fire evacuation plan is required
➢ Fire drills be conducted
quarterly or annually depending
on local laws
➢ Exit paths must be clear of any
obstructions
➢ Combination Type ABC
extinguishers are found in
most laboratories
✓Need not worry what type of
extinguisher to grab during
fire
➢ Type C extinguisher containing
CO2 or another chemical
to smother flames are
also used
✓Does not damage equipment
What are the classes of fires?
Class A,B,C,D,E,F
For class A fire, what fires are involved?
solid or organic materials, such as wood, plastics, paper, textiles, or coal
For class B fire, what fires are involved?
flammable liquids, such as gasoline, petroleum oil, paint, or diesel.
For class C fire, what fires are involved?
flammable gases, such as propane, butane, or methane.
For class D fire, what fires are involved?
combustible metals, such as magnesium, lithium, sodium, potassium, titanium, or aluminium
For class E fire, what fires are involved?
electrically energized equipment
For class F fire, what fires are involved?
cooking oils and fats, such as vegetable oil, sunflower oil, olive oil, maize oil, lard, or butter (typically those used for deep fat fryers).
What are the types of fire extinguishers?
Water, Powder, Foam, CO2, Wet chemical
What are suitable and not suitable to WATER for fire extinguishers?
SUITABLE
for wood, cloth, coal, plastics, paper, textile, and other solid material fires
NOT SUITABLE
all other types of fires.
What are suitable and not suitable to POWDER for fire extinguishers?
SUITABLE
For solid material, liquid, gas, and electrical fires
NOT SUITABLE
chip or fat pan fires or metal fires (unless it M28 or K2)
What are suitable and not suitable to FOAM for fire extinguishers?
SUITABLE
solid material and liquid fires
NOT SUITABLE
gas, metal, electrical, or chip and fat pan fires.
What are suitable and not suitable to CARBON DIOXIDE for fire extinguishers?
SUITABLE
For liquid and electrical fires.
NOT SUITABLE
gas, metal, or chip and fat pan fires.
What are suitable and not suitable to WET CHEMICAL for fire extinguishers?
SUITABLE
For fires that involve cooking oils and fats.
NOT SUITABLE
other types of fires ( use a more appropriate extinguisher).
What are IMPORTANT ACTIONS DURING FIRE?
Rescue any injured individual
Activate the fire alarm
Contain (smother) the fire, if feasible
(close fire doors)
Extinguish the fire, if possible
How to use fire extinguisher?
P
* Pull the pin on the fire extinguisher in order to break the
tamper seal.
A
* Aim the fire extinguisher low, with the nozzle pointed at the
base of the fire.
S
* Squeeze the handle of the fire extinguisher to release the
extinguishing agent.
S
* Sweep the nozzle from side to side while pointed at the base of
the fire until it is extinguished.
What are the things you should do for electrical safety?
➢ All sockets should be checked for
electrical grounding and leakage at
least annually
➢ No extension cords should be used
in the laboratory
How to handle of compress gasses?
➢ Gas Cylinders (CO2, Anaerobic Gas
mixture) contain pressurized gases and
must be properly handled and secured
➢ Fallen leaking cylinders
✓ MISSILES
❖Loss of life and destruction to property
How to handle of compress gasses for gas tank?
➢ should be chained
➢ Stored in well-ventilated area
➢ Metal cap should always be in place
when tank is not in use
➢ Should be transported chained in special
dolly
What are the basic concept of biosafety and biosecurity?
According to World Health Organization
Laboratory Biosafety Manual in 1983. (First
Edition)
Encouraged countries to accept and
implement basic concepts in biological safety
To develop national codes of practice for the
safe handling of pathogenic microorganisms
in laboratories within their geographical
borders.
History of biosafety and biosecurity
Laboratory Biosafety Manual in 1993. (Second
Edition)
many countries have used the expert
guidance provided in the manual to develop
such codes of practice
Laboratory Biosafety Manual in 2004. (Third Edition)
Addressing biological safety and security issues facing us in the
current millennium.
Stresses the importance of personal responsibility.
New chapters have been added on risk assessment, safe use of
recombinant DNA technology and transport of infectious
materials.
Recent world events have revealed new threats to public health
through deliberate misuse and release of microbiological agents
and toxins.
Introduces biosecurity concepts – the protection of
microbiological assets from theft, loss or diversion, which could
lead to the inappropriate use of these agents to cause public
health harm.
