Transcript MSDS Material Safety and Data Sheets

MSDS
Material Safety and
Data Sheets
MSDS (Material Safety Data
Sheets) are a widely used
system for cataloging
information on chemicals,
chemical compounds, and
chemical mixtures.
In the U.S., the Occupational
Safety and Health Administration
requires that MSDS be available
to employees for potentially
harmful substances handled in
the workplace under the Hazard
Communication regulation.
The MSDS is also required to be
made available to local fire
departments and local and state
emergency planning officials under
Section 311 of the Emergency
Planning and the Community Right
To Know
The American Chemical Society
defines Chemical Abstracts
Service Registry Numbers
(CAS numbers) which provide a
unique number for each chemical
and are also used internationally
in MSDSs.
A material safety data sheet
(MSDS) is a form containing data
regarding the properties of a
particular substance. The exact
format of an MSDS can vary
from source to source within a
country depending on how
specific is the national
requirement.
MSDS is intended to provide workers
and emergency personnel with
procedures for handling or working with
a substance in a safe manner, and
includes information such as physical
data (melting point, boiling point, flash
point, etc.), toxicity, health effects, first
aid, reactivity, storage, disposal,
protective equipment, and spill handling
procedures.
MSDS information may include
instructions for the safe use and
potential hazards associated with a
particular material or product.
MSDS can be found anywhere
chemicals are being used.
There is also a duty to properly
label substances on the basis
of physico-chemical, health
and/or environmental risk.
Labels can include hazard
symbols such as the European
Union standard black diagonal
cross on an orange background,
used to denote a harmful
substance .
An MSDS for a substance is
not primarily intended for use
by the general consumer,
focusing instead on the
hazards of working with the
material in an occupational
setting.
For example, an MSDS for a
cleaning solution is not highly
pertinent to someone who uses a
can of the cleaner once a year, but
is extremely important to someone
who does this in a confined space
for 40 hours a week.

Dental Emergencies
What are the Five Deadly Misconceptions?
5 Deadly Misconceptions:
1. A medical emergency will not happen to me.
2. A medical emergency will not happen in the office.
3. Calling 911 is the answer.
4. My staff and I will not panic during a medical emergency.
5. CPR is all we need to know.
Emergencies happen everyday. It's not a question of "if"you
have a medical emergency. It's a question of will you be
prepared to respond when you have a medical emergency.
The best way to handle the medical emergencies is to
realize the risk and be prepared.
Dental Emergencies
Records
It is important to document treatment of the medical
emergency. Recorded treatment should include:
 Drugs used
 Vital signs
 When 911 was called
 Example found at
www.emergencyActionGuide.com
Basic Drugs
Epinephrine 1:1000 injectable
 Oxygen with positive pressure administration
ability
 Nitroglycerin (sublingual or spray) vasodilator
 Bronchodialator
 Sugar
 Aspirin
 Histamine blocker
 Aromatic ammonic

Basic Equipment
1. Oxygen delivery system
2. Suction
3. Syringes
4. Magill forceps
Epinephrine
This is the drug of choice for a severe allergic
reaction and acute asthmatic attacks. The principle
effects of this drug are bronchodilation,
vasoconstriction and increased heart rate. This
should not be used on patients with ischemic heart
disease or significant fast heart rate.
Dosage: Auto injector and ampules of 1:1000
concentration
Adults 0.3 mg
Children 33-66 lbs use
EpiPen Jr.
Vasodilator – Nitroglycerine
(NTG)
Nitroglycerine is a vein and artery dilator that results
in increased cardiac output and reduced left
ventricular filling pressure. This is the drug of
choice for chest pain due to myocardial ischemia
and for severe hypertension. One tablet or spray
should be placed sublingually. If pain is not
relieved in 3-5 min. another tablet should be given
up to a maximum of 3 doses. It that does not relieve
the pain, myocardial infarction should be suspected.
Bronchodilator - Albuterol
Albuterol is used to treat a severe asthmatic attack.
It causes relaxation of the smooth muscles of the
bronchioles. It comes in a metered aerosol inhaler.
The patient is given one to two sprays to relieve the
bronchospasm.
Sugar – Glucose Source
Glucose is use to treat hypoglycemia
(low blood sugar) in a diabetic
patient. You can use any glucose
(sugar source). There are sugar
packets in the emergency kit and fruit
juice in downstairs refrigerator.
Aspirin
This is indicated for patients suffering a myocardial
infarction (heart attack). Aspirin has fever-reducing,
analgesic and antiplatelet effects. It is important
that the 325 mg tablet can be chewable since most
tablets have an enteric coating. You would give the
patient only one 325 mg tablet to chew. Do not use
this with patients who are having a stroke since you
do not know if the stroke is being caused by a clot or
a bleed occurring in the body.
In the case of 81 mg chewable Aspirin – give the
patient 4 tablets.
Antihistamine – Benadryl
Diphenhydramine
Benadryl is used to treat an allergic reaction or as a
local anesthetic in patients allergic to lidocaine. It
minimizes the release of histamine. This can be in
the emergency kit in tablet, liquid or injectable 50
mg/ml ampules.
Aromatic Ammonia –
Smelling Salts
This is a respiratory stimulant used
to treat respiratory depression and
syncope (fainting). It comes in a
vaporole and you can crush it under the nose. The
harsh odor irritates the mucous membrane and
stimulates the respiratory and vasomotor centers of
the medulla. Since syncope is one of the most
common medical emergencies, you may want to
keep one in each operatory.
Oxygen Delivery System
It is important to have an E cylinder with a bag
valve mask that can deliver close to 100% oxygen to
the patient. Indicated for syncope, cardiac
problems, and respiratory difficulties (except for
hyperventalation).
Diazepam - Valium
It is commonly used to treat anxiety.

For parenteral administration:

Solution for IV/IM injection - 5 mg/ml. 2 ml ampules and
syringes; 1 ml, 2 ml, 10 ml vials; 2 ml Tel-E-Ject; also contains 40%
propylene glycol, 10% ethyl alcohol, 5% sodium benzoate and
benzoic acid as buffers, and 1.5% benzyl alcohol as a preservative.
Notice: IM injection is largely less effective as the drug is injected
into a tetanic muscle with compressed muscular veins. This does not
allow the drug to reach the circulation rapidly.

Foreign Body in the Eye
Solid particle removal
 While patient looks down, pull the upper eyelid
down over the lower lid
 If not removed, turn the lower eyelid down and
examine for irritants
 Irrigate the eye
 Refer to physician if it cannot be removed
Caustic solution
 Thorough irrigation with water and prompt
evaluation by opthalmologist
Dislocated Jaw
To return the mandible to its normal position, the
dental provider should wrap both thumbs in a cloth
to protect them and place them directly on the
occlusal surfaces of the mandibular teeth. Fingers
should be placed under the person's mandible at the
curve. Press down and back with the thumbs and
pull up and forward with the fingers; mandible
should slip into place.
Avulsed Tooth
Tooth should only be handled by the crown
 Tooth should be rinsed with milk or normal saline
solution and gently placed back in the socket while
the person is transported for emergency care
 If the tooth cannot be placed in the socket the
patient should transport the tooth in low-fat milk or
a Save-A-Tooth system.
 Person should receive immediate emergency
treatment.
