Fire Safety
What should you do in case of a fire ?
Remember the acronym – RACE
Rescue – any people in danger
Alarm – activate the fire alarm
Contain – the fire by closing doors and windows
Extinguish – the fire if it is small enough
Patient Safety Monitoring in International Laboratories (SMILE) Program
10
Fire Safety
Types of Fire Extinguishers
A – Combustibles (paper, trash, cloth) B – Flammable liquids C – Electrical Equipment D – Combustible metals
(not Common)
Patient Safety Monitoring in International Laboratories (SMILE) Program
11
Fire Safety
How do you operate a fire extinguisher?
Remember PASS
Pull - the pin Aim – at the base of the Fire Squeeze - the handle Sweep - to cover the fire
Patient Safety Monitoring in International Laboratories (SMILE) Program
12
Fire Safety
Maintenance of Fire ExtinguishersFire extinguishers should be visually inspected on a monthly basis.
The inspection should assure that Fire extinguishers are: In their assigned place Not blocked or hidden Pressure gauges show adequate
pressure Pins and seals are in place No signs of damage The nozzles are free of blockages

Chemical Safety
How Do Chemicals enter the body?
Inhalation – breathing in (e.g. powders, fumes) Absorption – on skin or mucus membranes Ingestion – entry through the mouth Injection - through skin by foreign body
Patient Safety Monitoring in International Laboratories (SMILE) Program
15
Chemical Safety
Examples of Chemical Hazards Carcinogens – cancer Corrosives –burns Hepatotoxins –liver damage Mutagens-damage genetic materials in cells Nephrotoxins – Kidney damage Neurotoxins – damage to the nervous system Tertatogens – birth defects

Chemical Safety
How can you obtain information about the Chemicals you use?
Patient Safety Monitoring in International Laboratories (SMILE) Program
17
Chemical Safety
Material Safety Data Sheet (MSDS)
The following Data Can be found on MSDS sheets……….
Name of ChemicalPhysical Characteristics and hazardsHealth informationFirst Aid required if there is a spill or
exposureDate of most recent update
Patient Safety Monitoring in International Laboratories (SMILE) Program
18
Chemical Safety
MSDS Sheets Continued……….
Need to check for updates annually Highlight the name of the chemical and the first
aid section for easy access in an emergency Organize in alphabetical order Must be available to everyone all of the time The internet is also a good way to access MSDS
sheets Instrument manufacturers usually have MSDS
sheets available on their websites.

Chemical Exposures
First AIDFlush with plenty of water
For at least 15 minutes Remove contaminated clothing
Seek medical Attention

22
Chemical Safety
Liquid NitrogenWhen returning to the gaseous state:
Can displace oxygen from the air Can lead to asphyxiation
Will not support Life

Chemical Safety
Liquid Nitrogen – Precautions
Always wear safety equipmentAvoid use in a small enclosed areaAvoid prolonged breathing of vaporsAvoid rough handling of containersInstall O2 Monitors in LN work areas

SAFETY – Waste Disposal
Tips for safe disposal of laboratory waste:
Place all sharps in approved sharps containers Use goggles or full face shields to protect mucus
membranes from splashes when disposing of liquid waste or specimen tubes.
Refer to MSDS sheets for information on the safe disposal of chemicals

Bloodborne Pathogens
Bloodborne Pathogens
Patient Safety Monitoring in International Laboratories (SMILE) Program
36
Bloodborne Pathogens
What are bloodborne pathogens?Viruses, bacteria or other micro-organisms that are carried in the
bloodstream and are capable of causing disease.
Other body fluids that can spread bloodborne pathogens include: Blood products (plasma, platelets) Abdominal fluids Amniotic fluids Cerebrospinal fluids Vaginal secretions Semen

37
Bloodborne Pathogens
Most Common Bloodborne Pathogens
Hepatitis B
Hepatitis C
HIV

38
Bloodborne Pathogens
Standard Precautions
Standard Precautions replaces Universal Precautions – using Standard Precautions all
blood and body fluids are treated as infectious all of the time.
Patient Safety Monitoring in International Laboratories (SMILE) Program
39
Bloodborne Pathogens
Personal Protective Equipment (PPE)
Gloves
Safety glasses/Goggles
Lab coats (should be fluid resistant)
Face shields

PPE Continued…….
How much PPE should you use?
Wear as much or as little as you anticipate you will need to prevent blood and other infectious
materials from contact with your skin, mucus membranes and clothing.

41
Blood borne Pathogens
General Safety RulesHandle sharps with care: Do not recap needles or other sharps Do not bend or break off needles Dispose of sharps in puncture resistant containers
DO Not:
Eat, drink, smoke, apply cosmetics, take medication in areas where you are working with blood and other body fluids
Patient Safety Monitoring in International Laboratories (SMILE) Program
42
Bloodborne Pathogens
What should you do if there is a blood or body fluid exposure ?
Follow the post exposure prophylaxis (PEP) plan Wash puncture wounds with soap and water Flush affected mucus membranes with water Inform Safety Officer or administrative staff member Seek medical attention Complete an incident report form

Bloodborne Pathogens
Hand Washing
A basic but very important method of reducing your risk of infection.
