Definition: LD50
LD50 (Lethal Dose50) is the amount of a
substance that, when administered by
a defined route of entry (e.g. oral or
dermal) over a specified period of
time, is expected to cause the death of
50 per cent of a defined animalpopulation.

Definition: LC50
LC50 (Lethal Concentration50) is the
amount of a substance in air that,
when given by inhalation over a
specified period of time, is expected to
cause the death in 50 per cent of a
defined animal population.

When a Spill Strikes
1)Assess the risk
Minor Spill, handled by personnel within lab or
department. Minor spills should be cleaned-up at the
time of the spill.
Major Spill, isolate area. Major spillsmay require special treatment, equipment or
emergency assistance.

When a Spill Strikes
2) Select personal protective equipment (PPE) such as rubbergloves and goggles.
consult MSDS and other literature sources3) Confine the spill
Limit the spill area by blocking, diverting, or confining spill
Use absorbents, tiger tails, drain plugs, dikes
4) Stop the Source
5) DecontaminateDecontaminate site, personnel, & equipment by removing orneutralizing the hazardous materials
6) Complete Incident Report

MSDS Location
MSDSs are required to be accessible by you at all
times.
Dont necessarily have to be located in each lab
(although it is a good idea)
Ask your supervisor where they are located for your
area.
