Safety in Specimen Collection
• Goal is to recognize and eliminate hazards and
provide information on safety education so
employees can have a healthy, safe environment.
• OSHA Act of 1991 mandates the provision of a safe
working environment.
• Safety in specimen handling is critical to avoid
acquisition of infection.

Laboratory Safety
• Correct handling of specimens
– Specimens should be covered at all times
– Centrifuge specimens using appropriate
precautions.
– Dispose of samples in appropriate biohazardous
containers.
– Cover needles by properly utilizing the safety
equipment which require a one-handed method of
permanently covering the end of the needle.

• Safety advisory has been issued for the use of glass
capillary tubes to reduce the risk of injury due to
breakage and include the following:
– Avoid using capillary tubes made of glass.
– Use capillary tubes wrapped in puncture-resistant film.

• The hazard identification system consists of four small,
diamond-shaped symbols grouped into a larger diamond.
– Top diamond is red and indicates a flammability hazard.
– Diamond on right is yellow and indicates a reactivity-stability hazard,
these materials are capable of explosion or violent chemical reactions.
– Diamond on the left is blue and indicates a possible health hazard.
– Diamond on the bottom is white and indicates special hazard
information such as radioactivity, special biohazard, and other
dangerous elements.
– The system indicates the severity of the hazard using numerical
designations from 0 to 4, with 0 being no hazard and 4 being

Shock Prevention
•
Six actions
1. Correct the cause of shock if possible (e.g., control
bleeding).
2. Keep the victim lying down.
3. Keep the victim’s airway open. If he or she vomits, turn
head to the side so that the neck is arched.
4. In the absence of broken bones, elevate the victim’s
legs so that the head is lower than the trunk of the
body.
5. Keep the victim warm.
6. Call for emergency assistance.
