The document discusses responsibilities and components of a safety program for laboratories, clinics, and hospitals. It outlines the responsibilities of employers to establish safety policies and procedures, as well as the responsibilities of employees to follow safety protocols and report any unsafe conditions. Additionally, the document provides guidance on key safety topics like fire safety, chemical safety, and bloodborne pathogens.

Fire Safety
Maintenance of Fire Extinguishers
Fire 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

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

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.
